There are some weight loss products in today’s market that claim to assist with long term weight reduction, and others like Diethylpropion that are claimed to help with short term weight loss. This particular diet drug can only be attained with a doctor’s prescription. Diethylpropion is intended to be taken in conjunction with a healthy eating plan and regular exercise. Just like so many other diet products currently sold online and in nutrition stores, this diet drug aims to suppress the user’s appetite.

    Hi I would like to know how you get the diet pill without a dr’s prescription.? Please let me know. Thank you

    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.

    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.

    Started my first pill today… Feeling a little jittery, got lunch and could not finish the other half of the sandwich. It’s 3 hours later and Im not hungry at all.

    I have been taking Diethylpropion for a week now and have been feeling very Nauseas. Would this tablet be causing this please???


  • 9

    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.

    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!



    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.


  • 11

    I have some old pills (about 3 years old). Are they still good and not toxic?

    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 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

    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?



    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.



    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.

    I just started 4/18/2011 and I have not had any side effects however I am only taking it once a day the bottle says to take 3 times a day should I increase the amount I take?



    I’d follow what MD told you


  • 16

    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.


  • 17

    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


  • 21

    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!

    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.


  • 23

    This has been a miracle for me! Down 50 lbs in four months (along with low calorie, high protein diet and exercise) I have had no side effects.


  • 24

    i need to find a doctor in the detriot area who will prescribe me this medication. i need to have surgery, they won’t do it until i lose 35 pounds. i have been trying for 1 1/2/ years on my own. tenuate is the ONLY MEDICATION that will work for me . HATE HATE HATE PHENTERMINE, all i get is a dry mouth and headache.. i know i can loose the weight in 6 weeks, get my surgery done and get on with my life


  • 27

    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.

I have never been skinney always been very thick, I just want to get my back to my weight when I was in my 20s ranging anywhere from 145 to around 160. My size anywhere from a 7/8 to a 9/10. Please everyone wish me luck.


  • 32

    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.


  • 33

    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



    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… 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~!



    did u lose the weight strictly from the lack of hunger or are u on a excercise program as well, that sounds awsome… congrats!!!!!!!!!

    I’m on celexa 20mg is it safe to take this with tenuate and other asthmatic medications?


  • 36

    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

    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
