Anyone ever take this to lose weight? Any side effects?
Any info is appreciated.
Thank you,

I used to use it to get high. It definitely suppresses your appetite as it is a stimulant like amphetamine. It is slow release so you can take too much and not know for a while. One time I took it I was awake for three days and started hallucinating. It also can make your stomach hurt. It's also called 'duromine'.

I have taken this drug lately. I took it since March on a fairly continual basis. I lost 30 pounds. There are tons of side effects: sleeplessness, anxiety, dry skin, and more. I liked losing the weight, but I did suffer a lot of sleeplessness. I hope I never have to take it again. Be VERY careful with this drug.

I can definatly relate, I have been taking Phentermine for about 4 or 5 months now, and I too am noticing that I have been uping my dose. I am taking about 2 and half pills daily now but that really isnt working any more. Are their any withdrawl symptoms when stopping this drug? And Im slowly gaing the weight back too!

I would be very careful with phentermine use. I took it daily, just 1 each morning for about 4 years. I suspect it was the cause of many health problems I now experience. I have no actual proof of the following statements, its just the I have a real gut feeling that phentermine caused these problems.
Problem 1> I developed HIGH BLOOD PRESSURE during the time I was on phentermine. 160/100. I was in perfect health BP wise before my use. I now have to take blood pressure medication for the rest of my life.
problem #2 During the years I spent using this med I experience 3 cracked teeth that eventually had to be pulled. Each time I went to dentist I got the same result. Cracked tooth.Since I stopped using phentermine which has been over 3 years I have had absolutly no dental problems.
There were also emotional problems which I KNOW where caused by phentermine and that is irritabily. It almost cost me my marriage.
So keep this in mind when using this diet pill. It is not as innocent as you may think.

wow, that is so weird, my teeth have been giving me trouble since I have been on the Phentermine. They are very sensitive. How did you come off the Phentermine? Was it hard, or bearable? Do you know if its safe to mix taking Phentermine and an anti-anxiety pill? I take one sometimes at night to help me sleep. Thanks

I also have been takine phentermine (blue and clear) for 2-3 years now. I quit for 3 months because I was losing my temper and going nuts when I became mad at someone. After three months I couldn't take it anymore because I was feeling depressed and tired and I knew the phentermine would give me the energy again so I bought my first 30 pills. I have been taking them every other day without the knowledge of my husband until he finally caught on and confronted me.... he has now given me an ultamatum (sp?) quit taking them or he is leaving. I don't want him to leave but I don't want to stop taking them and be depressed and tired again. I see the addition but I don't know how to break it. What do I do and how do I do it?

I've used Phentermine in 1-2 year cycles for 20 yrs. I lost weight,hair, friends, jobs etc. to my drug abuse. One of my fave sayings was Die young-stay pretty. Well I'm 45 yrs.old now and have just developed Multiple Schlerosis. My Docs say all those stimulants INCLUDING EPHEDRA (I loved that-drug tests never detected it!) causes the myelin sheath(nerve covering) to erode. I thought these things would never happen to me. I used to love the complements I got about my body. I still have a great bod- but how attractive is it when I use a walker tostrut my stuff? God Bless

I have been abusing phentermine, 37.5mg, for over 7 years now. I am up to 3 pills a day now. I finally went cold turkey 3 days ago after having an argument with a peer at work.

Life is too short. The short-term gains (productivity and weight maintenance) are just not worth the deterioration in relationships I am discovering. I know my memory goes south also when I don't sleep enough.

Being an overweight addict hooked on pills to stay functional is sad. My personality has been based on these things. The challenge for me now is to re-define a new me. I lost my identity with these things. Also, I lacked emotion. I don't sleep with my wife because I am 'always thinking' of something,lol. I read on a meth board that this is called 'geeking'. Spending coutless hours daydreaming in your head.

Please, don't take these pills or do your best to stop. I have done a lot of things I regret while taking them, saying things I shouldn't have, etc.

Posted by: kswiss December 27, 2004, 11:55 AM
are u having any withdrawl symptoms? How are you doing? I am also taking 3 a day and have only been on them 5 months! I am a little scared now. I dont know what to expect when I stop taking them. Any advice?

Posted by: sscott30 December 27, 2004, 9:41 PM
You will feel very tired around day 4, you may even 'crash'. I did. You may cry. This is the worst of it. Around day 6 you will feel normal, but life will feel boring and bland.

This is the real challenge. Learning to live without it.

Posted by: kim January 15, 2005, 11:27 AM
Thanks so much for the info, I am still having a hard time stopping. I was wondering if loss of hair is a symptom of using this drug? My hair seems to be falling out everytime I brush it. And my teeth dont seem to be as healthy. Or should I say my gums. I hate to think what this si doing to my body! Again, THANKS

Posted by: KAY March 26, 2005, 3:16 PM
If you have ever taken adipex please stop. It has completely ruined my life. I have been off of them for 5 months now. There is a new treatment that uses magnets to recircuit the brain. This is repetitive transcranial magnetic stimulation. This drug has screwed up my brain. It you are taking this please stop. What good is a skinny body with out a brain. Is there any body out there suffering from these symptons?

Posted by: Bordan May 30, 2015, 8:11 PM
I abuse it.

I ate, but mostly snorted, 20, 37.5 mg,

In an 18 hour window. I don't think I can overdose.

It makes me happy and motivated.

Posted by: sandra777 March 8, 2016, 3:55 PM
phentermine almost ruined my life and almost destroyed my marriage.

don't ever take it!!!

Posted by: lm2118 April 23, 2016, 8:25 PM
My husband is taking this and i know he's not using it to lose weight. He has a history of opiate addiction. I had no idea he was taking this. He says the 90's fastin was the dangerous one, not the otc fastin that's available at CVS now. Someone please enlighten me. I'm nervous.

Posted by: Saralevi June 5, 2016, 8:49 AM
Phentermine is a stimulant.. It is not recommended but if you insist on extreme diet pills, then be ready for the side effects.. I advice against it.

Posted by: Felicia June 6, 2016, 6:10 PM
Phentermineis not recommended for it's health risks and side effects.. Avoid pills and lose weight the natural way, by cutting carbs and doing more exercise and drinking more water... That is the best way to lose weight. Avoid pills.

I would just like to comment for any one who is obese and is legitly prescribed phentermine. This is my first week taking 1 capsule of 37.5 mg every morning, so far I've felt less hungry and more awake. My doctor is only writing quantities of 30 capsules per month and only giving me 3 prescriptions total- that's it. It's to help start to lose weight and get back to a healthier lifestyle. I don't judge these other people, that's not my place. But do know that weight loss is a lifestyle change and this medicine works to kick start that process as well.

Posted by: lordoftheflies1 July 3, 2016, 3:48 AM
When I was at my heaviest my doctor prescribed me Phentermine, I have never done drugs but I can only say it's probably what crack or meth would feel like. I literally thought my chest was contracting at one point.

Maybe it works for those not as heavy as me, but It's not safe. My weight is still been going up, I'm trying to eat less and exercise more. Someday I will beat this or it will kill me. I accept that but I will not use phentermine ever again to try and solve my problem.

Posted by: Williams522 July 17, 2016, 10:05 PM
BLONDEFACE how has it been going? I too am taking it for obesity and legitimately prescribed 30pills and have to take it once a day. Thats all I am being prescribed. I had the dry mouth and other side effects. I've been taking it since June 6th so a little over a month now. Reading these reviews definitely worries me...I ran out last month and couldn't get an appointment until 3-4 days later. Didn't feel any withdrawals. I did hear the prescribed phen is way different then any online phen 37.5 and totally different for FenPhen fad in the 90's.

Posted by: saralevi September 11, 2016, 6:33 AM
Yes phentermine has serious side effects.. It has proven very effective for weight loss but you have to deal with the side effects

Posted by: canyazgan November 6, 2016, 5:27 AM
Phentermine has serious cardiovascular effects, might cause addition and the effects usually wear off after a few months. But it works for some people, so take at your own risk. FDA initially rejected it in 2010; but approved it in 2012 after further safety data was established. If you have cardiovascular disease, I would not touch it. If you decide to use it, do not drink alcohol as it will increase side effects.

tomorrow will be my second week on phentermine. But i had to check today because i had coffee for the second time in a week and oh boy! DO NOT DRINK CAFFEINE WITH THIS! The first week I had the normal side effects of insomnia, headaches, blurred vision, and racing around, but this week I was Just fine until I started again with the coffee. Makes my heart race, blurred my vision, and oh my goodness, try to get up and you will want to sit back down. Helps with libido, and menopause symptoms! I started at 181 and I am now 171.8 about 36.8 pounds to go. I usually walk my dogs in the AM for 30-35 min and eat right. Ok, I rarely eat because I’m not hungry. It does work!

I am 47 and have been using phemtermine off and on since I was about 31...I have found it so difficult to come off of, just talking myself back into taking it again and in the end I have struggled with my weight this entire time! The most I've ever taken has been 1 and a half a day but with also adding caffeine in my daily routine and when the effects seem to slow down as far as appetite control, I just eat a yo yo! I just want to stop it all together and be okay with that decision. I believe that it has caused problems In relationships with my family over the years and for that I am sad. Trying to come off beginning today with 1/2 pill for a week. Hoping all goes well

Has anyone taken Phentermine (37.5 mg) for weight loss and if so - what was your result? I am a 30 year old woman and would like to lose weight and get back in shape and I am thinking about asking my doctor to prescribe Phentermine 37.5 mg (I have a friend that is a nurse and recommends it) Assuming he prescribes it - I was wondering what everyone thought about it?

Posted by: PansyPuckett June 13, 2017, 7:22 AM
How well does Phentermine work?
How much weight have anyone lost and in what time frame?
Has anyone ever drank w/ it and had bad reactions.
I had a few drinks last night but it was only my first day on it and I was ok but I don't want to push it...

Posted by: Stvsbc August 1, 2017, 8:10 PM
Stay away from this stuff if you can! If you are a person with addictive tendencies, it is the worst thing you can do. Not everyone would go to the extremes I have, but the risk is real. I have taken phentermine and other amphetamines for 30 years. I recently quit and it is both the best and the hardest thing I have ever done. Right before I quit, I was taking in excess of 10 pills per day easy. Just pass on them if you can.

Posted by: Ben September 3, 2017, 4:30 PM
I've been taking phentermine for a few months and I stopped taking it for one day because of another health issue. In that time I felt like s*** until I took it today. I suspect that I've become reliant on it but it's still doing it's job. I consistently lose 3lb's a week just with the drug and weigh watchers diet. I haven't been able to do any exercise do to a knee injury. My hope is the drugs will assist me to get down to to a healthy weight and be able to maintain with weight watchers. But I'm still concerned that I'm becoming addicted.

Posted by: Throwaway January 2, 2018, 2:13 AM
Just wanted to add to this thread because i just recently had a run in with this stuff and found it affected me much differently from how other people say. I had an incident where I found these in a friends cupboard and mistook it for another medicine, leading me to accidentally take twice the recommended dose. It was fine at first, leading me to believe I had taken the correct one (I had taken it for a headache which, obviously, subsided) and went on with my night. Later I was sitting texting on my phone while my friend played some video game and I began to feel what I can only describe as a feeling of extreme relaxation and bliss, almost like a narcotic (not that I've tried those or EVER will) I must've spent the next two hours doing nothing but listening to Pearl Jam and watching them play the game. Though my mind was alert, it brought nothing but peaceful thoughts. My friend being a frequent marijuana user, we both wrote my strange behavior off as me being a lightweight and laughed it off. It wasn't until later after I began to feel "off" that I thought to check the bottle again and realized. My withdrawal symptoms were very much how people describe. I've suffered depression, but the restlessness, dizziness, and anxiety were a whole other beast. Not to mention the loss of appetite causing me to eat next to nothing. For the next days I would pace thought the night for hours on end, my brain repeating thoughts of how everyone hated me, I wasn't worthy of anything I had, and most of all that I NEEDED MORE. It was absolutely awful and I can only consider myself lucky as h--- I wasn't working that week or I can't imagine how bad it would've been. I've made a point to stay as far away from dangerous and addictive drugs so this has been a crazy experience for me. Even now though, far out of the withdrawal symptoms, I still find myself longing slightly for that wonderful feeling it gave me. It was near orgasmic and though my true depression doesn't near what withdrawal gave me, I still crave the escape. I'm far more effected by the negative withdrawal memories than I am by the craving, and I doubt I would be able to get more anyway, but I still feel strange knowing how susceptible I am to substance abuse.

I'm not sure what can be gained from this besides seeing the story of a person's first real addiction, but I guess I can also say that the one thing I found to help my withdrawals were ibuprofen. A bit ironic how the one thing that helped is the thing I should've taken in the first place

So I am a 20 year old female and my dietician prescribed me this pill to supress my hunger. I am 156 pounds and 5'5, goal weight is 130 and I loose weight very slowly for some reason so he gave me this pill. Taking 37.5 mg once a day. He only prescribed me the pill for 15 days and said that after seeing how I react to it he would prescribe it for one more month and no longer than that. My 15 days are almost up. I have experienced no negative side effects whatsoever. I feel energized, I feel happy and talkative (more than usual), in fact, I suffer from chronic pain and although the pain is there it just doesn't really seem to bother me. I basically feel tipsy during the daya fter taking it and its quite an enjoyable feeling. Also have been loosin 1 pound every two days because I rarely feel hungry now. I feel great and really am not looking forward to whenever I may need to stop taking these. They make me feel so nice... I am afraid these may be signs of the development of an addiction or dependency. Any thoughts? thank you!

I've been taking duromine 30 for 4 months now as a kickstart to my metabolism after loosing 30kg and wanting to loose another 10kg. Every time I stop taking them I can't function all I want to do is sleep after a week I was becoming normal again after 2 weeks I was fine. Then a bit later I decided to take them again because wanting to loose more weight. I didn't loose I just found my body needing them. So I can see these drugs are very addictive. My advice for giving them up is to just ride through the tiredness after a week you will start to feel normal again.

Posted by: Sean April 21, 2018, 8:34 PM
I'm someone with a history of addiction but let me nust state my opinion: as long as you take it as prescribed, this prescription, i.e. Phentermine is nearly NOT addictive as people believe, in terms of causing cravings or inducing withdrawal aka producing dependence. I've been on the same dose of 37.5mg once a day in the morning for over a year now, and had to abruptly discontinue it during 2-3 seperate inpatient hospitalizations that averaged about a week each, but other than those 2-3 weeks, I've taken it consistently as prescribed. The only noticeable side effects of long term uae have been decreaced effectiveness (tolerance), but I didn't compensate by increasing the dose or anything, and the other side effect is (increased) muscular tension, which sometimes causes tension headaches or muscle spasms. But it's manageable and worth the benefits attained. On the other side of the coin,,, When abruptly stopping this medication after long periods of use, I noticed two main things: Extreme Lethargy/Fatigue and Significantly Increased Hunger - both peaking in intensity within the first 2-4 days. But other than that, I would say there was no Withdrawals. Especially no Amphetamine like withdrawals of: extreme hostility/aggression, irritibility, sleeplessness, restlessness, cobfusion,depresion, anxiety, etc.

This does not sound any different than Methamphetamine's. Or other amphetamines for that matter. Just because it is a prescription does not make it different. Maybe more pure, but not less harmful. Anyone interested in continuing to take these diet pulls should check out the Judy Gardland story. She became addicted to these due to the pressure to be thin and work very long hours and she had lots of issue with depression throughout her life. Finally committed suicide by taking an overdose at a very young age. A tragic story. Many good support groups to help people overcome addictions and free too.

I was very much into stimulants, anything to kill my appetite and gives me extraordinary energy or concentration. My DOC was Ritalin. I'm in a 6 month recovery and struggling to lose weight. I dream of it from time to time and sometimes I really miss it. But it caused me so much bad choices and s***ty moods made me spend time with people I pray I never meet again.
