What Is Diethylpropion? 

Researchers into weight loss supplements and medication have long asked, “what is Diethylpropion?”

Diethylpropion hydrochloride is an amphetamine-based stimulant that is employed as a suppressant to reduce appetite. The central nervous system is targeted by the drug’s mode of action and as a result, a significant loss of appetite is recorded.

Diethylpropion hydrochloride is usually used in the treatment of individuals with obesity. [1]

Diethylpropion belongs in the “sympathomimetic amines’ class of drugs. Drugs in this class are able to modify the behavioral patterns of consumers by affecting certain aspects of the brain and nervous system. This is how Diethylpropion is able to suppress appetite in users who are usually overweight.[2]

Diethylpropion is also an anorectic or anorexigenic drug, used to artificially suppress cravings or hunger.

When Did Diethylpropion Start?

Diethylpropion was introduced in 1959 as an appetite suppressant or suppressor. It is a generic product with different brands producing variants using the same active ingredient, Diethylpropion HCl.

The benefits of the drug have made it one of the most popular choices for people looking to lose weight safely and easily.

Claims Of Diethylpropion

The claims of the Diethylpropion manufacturers is that the product helps obese people lose excess weight by suppressing their appetite.

This claim is supported by extensive research into the active ingredient – diethylpropion hydrochloride. It has been shown to have a proven impact on the central nervous system of the users and reduce the urge to eat.

This decrease in appetite, along with dieting and exercising has a quantifiable effect on weight loss.

User reviews on the internet also support this assertion, with thousands of customers leaving positive reviews on the effects of Diethylpropion.

On drug.com, Diethylpropion polled a 9.1 rating from close to 100 reviewers who testified the weight loss capability of the medication.


Benefits Of Diethylpropion

Using Diethylpropion correctly will lead to a reduction in weight in the long run. The drug is prescribed to overweight and obese people who wish to burn calories and lose weight. The benefits of losing excess weight and tackling obesity includes:

  • Reduced risk of heart diseases
  • Prevention of diabetes
  • Maintaining healthy blood pressure

Extreme Weight Loss

Diethylpropion And Weight Loss

The consensus among users and reputable science publications is that Diethylproprion can be effective as a medication for weight loss in obese people.

There is no research showing the exact mechanism of how the drug causes weight loss but it has been noted amongst several users.

Diethylpropion works by suppressing the urge to eat and take in excessive calories.

Diethylpropion 25 mg or 75 mg extended-release tablets are to be used in tandem with suitable dieting plans and exercises. Lower caloric intake coupled with exercise is a proven way to lose weight. Diethylpropion hydrochloride is usually prescribed to individuals with a body mass index range (BMI) of at least 30Kg/m². [1]

A study has shown that persons administered Diethylpropion are likely to lose about 10% more body fat than those who were on a placebo in the study.

Further evidence of Diethylpropion 25 mg and 75 mg effectiveness at losing weight is the predominantly positive reviews that have been given by users. Almost 80% of responders online have given an above average rating to the weight loss benefits of Diethylpropion.

Users have also reported that after discontinuing medication there must be a sustained effort at dieting and regular exercise otherwise the drug-induced weight loss becomes reversed.

How Does Diethylpropion Work?

Diethylpropion functions as an appetite suppressant by stimulating the central nervous system into producing catecholamines.

These catecholamines are neurotransmitters that, when produced by the body in high quantities, suppress the sensation of hunger and trigger a loss of appetite.

Examples of these neurotransmitters are dopamine and norepinephrine.

Essentially Diethylpropion tricks the brain into getting into an excited state, where the body has no need for food or has the urge to binge eat.

Conditions Treated With Diethylpropion

Diethylpropion is used as an appetite suppressor in the treatment of obesity.

Obesity is the only FDA approved condition this medication treats but there is a possibility that the drug is abused for recreational purposes.

Side Effects

Side Effects Of Diethylpropion

The mode of action of Diethylproprion is to affect the central nervous system, so some of the effects might be of a cognitive and psychological nature.

Patients should ensure that they monitor their reaction to this drug as they administer it to treat obesity.

Individuals with allergies should ensure they are not at risk of a reaction with any of the active or inactive ingredients in this drug.[1]

Any signs of allergic reaction must be treated as a medical emergency (signs include; swollen tongue and throat, rashes and hives, shortness of breath and tightening of the chest).

The other side effects that may accompany usage of Diethylpropion include but are not restricted to the following:

  • Rashes
  • High Blood Pressure
  • Chronic headaches
  • Light-headedness
  • Anxiety
  • Fever
  • Chills
  • Fatigue

How To Take Diethylpropion

To take Diethylpropion, you have to confirm with the doctor or health care practitioner what type of medication you have got. You may be given either the immediate release form of Diethylpropion 25 mg or the extended release Diethylpropion 75 mg tablet. They have the same results, only differing in the mechanism.

The Diethylpropion 25 mg immediate release form only lasts in the bloodstream until the next dose, while the extended release, Diethylpropion 75 mg tablets, lingers for 24 hours in the bloodstream until another pill has to be taken. The immediate release form is taken three times a day, while the extended release form is administered just once a day.

To take Diethylpropion 25 mg tablets, you have to take it using water, about an hour before meals, three times daily. Be sure to consume it before it gets too late at night as the drug may cause insomnia. The Diethylpropion 75 mg tablets are to be consumed just once, usually around noon, daily.

The tablets for the extended-release form must not be tampered with or else it loses its efficacy and mechanism for slowly dispensing the medication. Do not crush, chew or blend the tablets.

While on this medication, keep regularly-updated records on your weight progress. Ideally, around 4 pounds of weight should be lost in the first month of administration. If there is no noticeable weight loss, report to your doctor so he may put you on a different Diethylpropion dosage or drug altogether.

Product Warnings

Warnings When Taking Diethylpropion

Diethylpropion is a stimulant that is taken by obese patients. Warnings about taking the drugs are available and precaution should be taken when administering the drugs to prevent triggering potentially fatal side effects.

The warnings for Diethylpropion are as follows:

Heart Diseases

Do not consume Diethylpropion if you have a pre-existing heart condition. Conditions include pulmonary hypertension, coronary heart disease, and high blood pressure. Taking this medication with these pre-existing conditions can worsen them and trigger a potentially fatal cardiac arrest.

Risk of Drug Abuse

Although compared to amphetamines, Diethylpropion has a lower risk of drug abuse, it is still important to ensure any person who has a history of abusing drugs is not prescribed this. It is a medication that suppresses the nervous system and a dependence can develop over continued use.

Other Diet Pills

Do not consume Diethylpropion with other diet pills. The risk of potentially overdosing on similar substances is too high to combine diet medication without the absolute approval of a doctor.

MAO Inhibitors

MAO inhibitors are a class of medication that are used to treat depression. If you have been prescribed them and have used any of the following inhibitors in the last 14 days, it might be dangerous to administer.

  • Diethylpropion HCl
  • Isocarboxazid
  • Linezolid
  • Methylene Blue Injection
  • Phenelzine
  • Rasagiline
  • Selegiline
  • Tranylcypromine


Ensure the drug is administered only in a calm and relaxed state. Consuming while agitated may lead to an extremely volatile response and pattern of behavior. There has been a reported case of schizophrenic-like symptoms aggravated by the consumption of this medicine. [4]

Pregnant and Nursing Mothers

Diethylpropion should not be administered to pregnant women. There is insufficient research into the effect of the medication on a developing fetus and as such the risks cannot be quantified. Nursing mothers should also avoid taking this medication while breastfeeding babies. The drug is liable to contaminate the breastmilk and as a result, lead to the baby becoming dependent.


Diethylpropion is banned for administration to anyone below the age of 16. This is to prevent permanent damage to an underdeveloped nervous system.

Addiction and Withdrawal

Diethylpropion should not be consumed for more than a few weeks at a time. Due to its nature as a stimulant, long, extended use is highly discouraged to prevent addiction.

Tolerance to diethylpropion HCl develops after use for a few weeks and users may feel the need to increase their daily consumption to feel the same effects – this devolves slowly into addiction. Regularly consult your doctor to know the duration which you can safely administer Diethylpropion.

Withdrawal is another dangerous potential risk with extended use of Diethylpropion. The drug should not be abruptly discontinued; rather a doctor puts you on slowly-reducing Diethylpropion dosages to help taper off the effects and dependence with no withdrawal symptoms.


Do not consume alcohol while using Diethylpropion. An interaction between alcohol and this medication can lead to a higher risk of the listed side effects. Alcohol and Diethylpropion combined will further lessen your senses and lead to a slower reaction rate. Do not operate any deadly, heavy, automated or manual vehicles or machinery after consuming alcohol or Diethylpropion.

Using Diethylpropion with alcohol can increase the risk of cardiovascular side effects such as increased heart rate, chest pain, or blood pressure changes. In addition, you may also be more likely to experience nervous system side effects such as dizziness, drowsiness, depression, and difficulty concentrating.

You should avoid or limit the use of alcohol while being treated with Diethylpropion. Do not swallow this medication with alcoholic drinks or consume alcohol while on Diethylpropion in order to prevent fatal side effects, impaired judgment and potential accidents.

Ensure you also fully disclose your medical history and prior conditions to your healthcare practitioner. A list of previous and current medications should also be presented to your doctor.

Types Of Diethylpropion 

Diethylpropion comes in two forms: Diethylpropion 25 mg and Diethylpropion 75 mg tablets.

The former is an immediate release form of diethylpropion hydrochloride, dispensing the active ingredient instantly into the bloodstream. The Diethylpropion remains in the bloodstream for about eight hours before it begins to lose efficacy; this is when another Diethylpropion dosage is taken.

The Diethylpropion 75 mg tablets are extended-release tablets that are taken once, at noon, daily. The mechanism of the tablets ensures that the active ingredient, diethylpropion hydrochloride remains in the bloodstream 24/7 without any need to take more than one tablet.

The advantages of the immediate release tablets are that it works instantaneously and the chemical gets introduced into the bloodstream fast. It is also easier to adjust the Diethylpropion dosage in cases where the response is either too high or too low.

Diethylpropion 75 mg tablets, the extended-release form, are able to constantly provide the needed medication for the entire day. The ability to be able to carry out daily tasks without the need to watch the time for a dose of medication is valued.

Diethylpropion 75 mg tablets are also suitable when there is a chance the patient might not be able to have access to his or her Diethylpropion 25 mg dose at the appropriate time.

Science Behind Diethylpropion – “Lacking Clinical Research”

The clinical research surrounding Diethylpropion is mixed. While some claim it is an effective solution to obesity, others say it isn’t, and even more suggest that it is effective, but comes with extreme risks that outweigh the benefits. [6] Overall, we can’t be so sure about the medicine.

Here at DietSpotlight, we like to see supportive science before we can recommend any product.

The Bottom Line – Does Diethylpropion Work?

So, what’s the real deal with Diethylpropion? We do appreciate that the drug has been around for almost 60 years and has some clinical research backing up its ability to help obese patients lose weight.

However, we got a bit concerned when we learned more about the side effects and lack of results for some customers. We are hesitant to give a positive recommendation for this product because of this.

If you’d like to drop some pounds, we recommend selecting a supplement that is supported by published clinical research, with safe ingredients that don’t cause harsh side effects.

Among the best products we’ve seen this year is one called Burn HD. The four ingredients have been clinically tested and shown to help boost metabolism and increase fat loss. There are no reports of negative side effects and users across the web report amazing results.

Plus, the company that makes Burn HD is quite confident in the formula, so they’re offering customers a Special Trial Offer – nice touch.

A must try..

        • Your Name

          You should not break the 75 mg pills. The 75 mg pills are gradual release pills and if you break too much of the medication can be released into your system which is not safe.
          If 75 mg is too much for you. I’d suggest taking the 25 mg pills twice a day. This is what my doctor told me.

  •  Lost 8 pounds in 2 weeks, no side effects !
    George (Verified User)

    Started taking diethylpopion on 5/11/2016 and have lost about 8 pounds in two weeks. Goal is to lose 45lbs but i went down to 224lbs from 235lbs and gained back 3lbs so not sure if I’ve hit a plateau or not. Going back for my follow up visit in a few days time and will ask for a higher dosage since this is only 25mg taken twice a day. No side effects other than the need to pee often but i was already told about that by a friend who took it and lost 35lbs.

  •  Very Very happy with this medication.
    Jen (Verified User)

    I started this medication 3 weeks ago. I was nervous to start because several months ago I tried Phentermine and I had horrific side-effects with it. But I am happy to say not with Diethylpropion. I had a headache the first few days. 3 days of some insomnia, a bit jittery first two days…..but that has all passed. I have been on this 3 weeks and have lost 11.4 pounds. Very Very happy with this medication. Totally controls my hunger and no desire for binge snacking. I am sticking to a diet of approximately 900 – 1000 calories and walking almost every day for a half hour.

  •  Fantastic product

  • New to the drug. Just have a few questions and want feedback on people who have taken it.
    Heather (Verified User)

    This is my 3rd day on this medication. I can tell it helps me be not as hungry. Just worried about all the listed side effects. None so far but a mild headache my first day but I always have headaches so it probably wasn’t even the drug. Taking the 75mg ER. My hungry time is morning- mid afternoon so I take it around 7:00am. How long should the med last in your system if I take at 7:00am?

  • I started this medicine

    I started this medicine yesterday–took it at 6 AM. I didn’t get to sleep until nearly 2 AM. Can one break the 75 mg tablet in two? II think that might be better for me, but the directions clearly say not to do so.

    • Your Name

      I was told to break 75mg in half and take only half a tablet for the first 2 days then on day 3 to take a whole pill and carry on with whole 75mg pills each day afterwards

      • Laynie

        I just responded to this question to another person. I meant to put it to your question
        Do not break the 75 mg, because since it is a release pill if u break it it will release a unsafe amount into your system right away. If you are not tolerating the 75 pill, then you can get a prescription for the 25 mg pills and take it twice a day. My internal medicine doctor told me this 2 days ago, when he first prescribed it for me. So Do Not break in half the 75 mg pill, trust me.

    • Your Name

      My doctor told me to start off by breaking it in half. She said once I see how it affects me over 3-5 days, then I can try taking the whole 75 mg. I have not started taking it because I’m afraid it will keep me from sleeping, which I already have problems.

    • William

      I take sleeping pills and I have no issues, but yes the first day I felt asleep at 230am.

    I have been taking this Diethylproprion for about 2 months, while I did loose weight and it helped get started on a healthy diet and exercising, I would not recommend this diet pill or any other diet pill if you taking antidepressants and have problems with depression. While I was happy I was loosing weight I felt I had this dark cloud over me. I cried for no reason , my depression got worse. I have always been weary about taking diet pills only because my depression I gave into this one, my doctor had explained it was a diet pill with the least side affects well not true. If you suffer from depression stay away from this and all diet pills it’s just not worth it.

  •  When should I actually feel something - Anything, should I feel the first pill?
    Leo (Verified User)

    I just bought one weeks supply of diethylpropion from a very reputable chain of clinics here in the UK and took my first pill today. It has had absolutely no effect of me whatsoever. I felt hungry when I normally do, I am tired now so I’m gonna go to bed in half an hour and I don’t feel anything by way of jitters, increased energy or any of the other known side-effects. The pills I bought don’t have any markings on them either, just the score to break them in half, so I’m worrying that I’ve bought fakes and wasted my money. When should I actually feel something – anything? Should I feel the first pill? Help and advice very much needed.

      If taking 75mg like I am, take one mid morning 30 min before eating with plenty of water. My pills don’t have any writing on them either.

  • Does anybody know if losing hair side effect goes away?
    Tanya (Verified User)

    I have been talking Diethylpropion for about 2 months and have been losing a decent amount of hair. I see this can be a side effect. Does anybody know if this side effect goes away?? I’m desperate for answers!

    • quickslimuk

      I have previously used Diethylpropion for 12 weeks, noticed a lot of hair loss to start with but for me it did stop after first 6 weeks. Have started taking them again 2 days ago but have not noticed any adverse effects so far.

  •  Side effects of Diethylpropion
    Martha (Verified User)

    I started taking this rx along with HCTZ and Potassium about 3 weeks ago. So far so good. I have lost 12 pounds. I have never been able to lose weight so quick because my major problem is over eating when im bored or anxious even though I am active. I am concerned about the side effects and I have noticed getting a little more anxious than normal. Also, I found what Susan said aboce interesting… My schedule changes on the weekends so I dont take the tabs 3 times a day and I got very depressed. Not sure if its related.

  •  I feel a lot better
    kayley (Verified User)

    I have been taking these tablets now for 2 weeks and have lost 17 lbs,I was speaking to my doctor and he told me that even when i come off the tablets the only reason that i would put any weight back on would be if i started to eat more. these tablets don’t speed up metabolism or loose the weight for you, they just trick your body into thinking that it’s full so you don’t eat as much. There working a treat for me and i was worried because of my asthma but if anything they have eased my breathing because of the weight. Overall i feel alot better than i ever have i’m currently taking the once a day tablet and i have no side-effects. I’d recommend them to anyone. Good luck

  • Didn't loose weight
    Lynn (Verified User)

    I have heard that after getting off diethylpropion or similar diet aids your body’s metabolism is effected making it so that you will easily gain back all the weight you’ve lost and then some, and then will have an extremely hard time losing the weight again. My sister lost a great deal of weight, looked fantasti, and now she weighs over two hundred and some pounds. She can’t loose weight even if she diets and exercises. Has anyone been on this drug and then off for awhile? What did you experience?

    • MekaG1973

      I lost a total of 50lbs on this medication over a year ago and have only gained about 8lbs back. I have not taken the pills since July of 2020. Everyones body is different. Maybe your sister should try something different.

    • Meccarn29

      I think there my be some truth to the pills changing your metabolism. I was on phentermine in 2010 intermittently and diethylproprion a couple of months ago for about a month or so. I didn’t even take it everyday. Now, I am literally exhausting myself at the gym almost everyday and eating about 1200 calories a day and still can’t lose the weight. While I didn’t lose the weight as fast as when I was on the appetite suppressants, I was able to lose some weight through diet and exercise. Now, I can’t lose any. I don’t know what I’m going to do now, I hope this is only temporary. I am truly sorry I took the pills in the first place. I am 38 years old, 5’9″ and 190lbs.

  •  Feel sick, jittery, or just abnormal
    Anonymous (Verified User)

    I’ve been taking diethylpropion for about 8 months (I take it every other day, or sometimes a few days in a row but then give myself a break). It works. The best part is that the side effects do go away after a few weeks. My body is actually very sensitive to medication and I always seem to get the rare and horrible side effects but this has been working beautifully and makes me feel healthier. My appetite is finally controlled and I don’t obsess about food or when I’m going to eat next. I definitely recommend it as I’ve tried many other weight loss pills but have had to discontinue use because they made me feel sick, jittery, or just abnormal in general.If you take it continuously, it will stop working but if you trick your body by not taking it for a day or two, it will continue to work for months.

  • i hope they work for me aswell

  • safe to take

    i got these pills a while ago and never used them, however in the last year i have put on a stone, can anyone tell me if they are safe to take if i am taking citalopram, they are 25mg

    • Sabrina

      They are not to be used with anti depressants or anti anxiety meds.

  • Susan

    I was prescribed Diethylpropion three years ago along with hydrochlorothiazide and potassium. I took them and lost a LOT of weight – about 25 lbs – but I was always really hyper, irritable and a had lots of heart palpitations, which the doctor said was just a coincidence that they started when I started the diethylpropion. Whenever I STOP diethyl… I get really, really, really depressed for a few days. (Scary depressed, you know what I mean?) So I stopped taking it for a year, I regained 20 lbs, although I exercise 4-5 days a week and eat fairly well. I took it last month for two weeks, lost 6 lbs, heart palpitations so strong they were scary (they never completely went away). Major depression for a week. So I’ve weighed my options. I’ve given up on just diet and exercise. In the morning, I resume this regimen. I figure if the heart palpitations kill me, at least I’ll be a good looking corpse. I’m 5’9″, 173 lbs and 46 yrs old. I look good at 155 or so, pudgy thereafter. Wish me luck!

  •  It works but it have side effects.
    Angela (Verified User)

    I just started taking Diethylpropion on Wednesday. It’s Friday, I am down 5 pounds. I have been on the elliptical for 50 minutes a day on level 2/4. I am very sensitive to pseudo-ephedrine products, so I was fearful of feeling jittery. I too felt sort of light-headed, or “different” on Wednesday, but not yesterday or today. Thank you all for sharing your experiences. This has been very encouraging for me.

  •  This pill really works!
    Anonymous (Verified User)

    I have been taking this med for 2 month and have went from a size 9 to 6 and some size 6 are too big. I have notice that my hair is not grow as fast as it use too but no hair loss, lower growing but I decided to take a hair pill. This pill really works!

    • Rose

      what type of hair pill did you take

      • Laynie

        I suggest for helping with hair growth and texture taking Biotin. It’s in the vitamin.
        I just started yesterday taking Diethylpropion. I started Biotin 6 months ago wanting to grow out a short. I think it has helped with the growth. It also helps nail growth.
        I did notice with my 1st dose of Diethylpropion yesterday it decreased my appetite immediately. Do remember to eat within hour of taking regardless if you are hungry. I waited too long 2.5 hrs and I started getting jittery. I did a small amount of coffee first so that affected me too. But once I ate the jittery feeling went away.
        I read after your 1st meal within 3 hrs have at least some fruit not go with nothing till dinner.
        If I dont have fresh fruit going to keep a supply of canned fruit.
        I did weigh 2.4 lbs less than the first morning. Who knows if just water. I hope I do lose weight and have no side affects so I can stay on the medication and get my BMI below 30. 30 and up is obese. That is why my dr put me on the medicine. Plus the last few years my weight has gone up each year. I need to get weight down for numerous health reasons.

  •  Like it very much.
    MekaG1973 (Verified User)

    I took my 2st pill on 2/8/10 as of today I am down a total of 10lbs. After my 1st couple of days I started walking at least 30 min 3 or 4 days a week. I drink about a 1/2 gallon of water a day. The 1st day I took the pill I felt a little light headed, but after that it has been easy. It complete controls my appetite. I dont have the urge to snack. In fact some days I have to remember to eat. I don’t have any issues sleeping so I guess it would be safe to say so far so good. Another 20 to 25 lbs to go.

    Kira (Verified User)

    My doctor prescribed diethylpropion for my weight regimen. I must admit at first I was a little concerned about taking diet pills because would be my first experience with them. I have been taking it for two weeks and I have lost 4 pounds already! I have not experienced any of the side effects listed. It has certaintly surpressed my appetite. I don’t have the urge to even snack which was always a problem area for me. I recommend this pill to anyone.

  •  I'm 2 weeks in and down 15 lbs
    Beth (Verified User)

    I was just given a prescription for this and have to agree with Judith in that it has majorly curbed my appetite.
    Also, I have experienced none of the side effects myself.
    I was concerned with the “difficulty sleeping” part as I run from 4a-8p 5 days a week, but I have had NO trouble sleeping, in fact I think I am sleeping better.

    As for asthma, I have the occassional acute attack and my cod said not a problem.
    Ans according to her, it’s the safe Phen of Phen-Phen.

    Runs about $40/month without insurance approval (my doc had to submit PW for approval before I could use my insurance to cover it.

    I have nothing bad to say so far (I’m 2 weeks in and down 15 lbs and eat pretty close to vegetarian – before the pill)
    This was the kick I needed

    • angela

      my Doctor first gave me a Rx for phentermine.i took it one day and totally freaked out on it. I called him and let him know what had happened, he then wrote me a new Rx for diethylpropion…..im wondering if this is gonna gve me that ‘speedy’ feeling like phen did. Have you taken both?? i dont mind if the weight loss is slower…i just dont want it to trigget my anxiety again. i have not filled the script yet…want to get some feedback first. Im hoping that Diethylpropion is not as strong as phen. pleaseeeee respond! thanks~!

    My doctor has prescribed diethylpopion to assist me with my weight loss. Are there any research studies that are available to me to decide if I really want to take this medication? I took Phen-Fen in the early-mid 1990s & loved it & sucessfully lost weight & kept it off for several years after. Is this anything like Phen-Fen?

      i used this pill after giving birth to my daughter and lost 60 in less then 2 months i was excersing everyother day , but wheni went to use it with after i gave birth to my son, it didnt work for me anymore,, its realy a great pill

      • valerie evans

        sometimes you just have to give the body a “rest”. let your hormones calm down and try itagainwhen he is a few monthes older. .. I’ll bet it will work just fine.. consider if you had a C-section this time or had different anesthesia, whether you breast-fed,for how long. also, consider if you had different anesthesia for your son.. take time off, then give it another shot..I’ll bet you will not be disappointed
