Phentermine Anyone Have Strange Side Effects? (Page 17)
(Newest replies first)

Updated

I just started taking this medicine for weight loss. I am having hot flashes and cold chills, terrible headache and a tingly head. I feel awful. Has anybody taken this and had the same reaction? If so did it pass after a few days? Gotta say this...I am not ever hungry! Like to hear from anyone that has taken this med. Thanks :)

Yea.... Since the medication acts like dieuretic, I expect that's one of the things you can count on. I have a glass of water all the time and I still have that problem as well.

Has anyone had any bowel problems while on this pill?
This is my second time taking phentermine and I have been having bad contipation. I drink Lots of water and probiotics but nothing works unless I take a stool softener.

I took it for 6 months about a year ago and I lost 25 lbs. my anxiety got worse and I got the shakes. The energy was awesome but it's definitly hard to sleep. I started back up Friday and I'm still feeling like I'm speeding. Hopefully it stops after the first week like the last time. Any tips to help with the side effects?

I started phentermine time release 6 days ago and having horrible side effects, hot, feel flu like, lethargic.no increased energy at all. increase in bp and pulse. Dr started me on topamax as well but i can't handle side effects. Seriously thinkihng of stopping phentermine.. insomnia, crying spells, irritability. i took the tablet form 3 years ago and broke it in half, so maybe this time release is too much.. calling dr tomorrow... no fun.. i wanted it to work so bad.. appetite decreased drastically.. it's just the other side effects. 3 am and can't sleep..

So here's an update on the erectile dysfunction I experienced with Phentermine.

I decided it was time to know the truth. So on October 23rd I stopped taking the Phentermine. That was a Tuesday; on Saturday morning, to my delight, I had morning "wood". Hadn't seen that in some time. However, that was a lone event, as it hasn't happened again. There was still hyper-sensitivity, but for the most part the condition was unchanged. I was unable to get an erection by any means other than some direct, and continued, manual stimulation. When I quit, so did it. My fears were gaining on me. But on Monday things seemed different. Very difficult to qualify that statement, but some of the old methods, reading, movies, etc. were having an effect. On Tuesday, the 8th day after stopping the Phentermine, things seemed fully recovered. Without making this an entry that may belong on a different site, let's just say the "Ops Check" later that evening proved successful.

I hope this gives the next guy a little relief from the terror of thinking you may never get that back. I did find one site that stated once you have ED as a result of Phentermine, it's permanent. At least in my case, that statement is false.

I started taking Phentermine (37.5mg) on Aug 7th. By August 17th I felt so horrible I quit taking it. My heart was racing and I just felt generally bad all over. Talked with my doctor about it and he asked me to resume the medication and we'd touch base in two weeks. So, reluctantly, I started taking them again on Oct 3rd and haven't missed a pill yet. To date, I've lost 24 pounds. I am pleased that the ill feelings never came back. The dry mouth is constant. I always have a glass of water with me while I'm home. I work from home, so that's pretty much all the time. I've experienced any headaches, but I do keep hydrated. I also get these smells and tastes, seemingly phantom. Very strange smell too. Nothing I've smelt before. It's annoying, but easy enough to cope with.

The problem I'm MOST concerned with is erectile dysfunction that seems to have joined the party. I've heard it happens, and that "your body will adapt and function will return". I read in earlier comments about seaman leakage, I haven't seen that, hope it's not in my future. Also saw a mention of impotence, but no clue as to how long before I can start to hope to get past this. Because this will be a deal breaker. So, anyone?

I just started Phen yesterday, I took it ten years ago with good results but came down with thyroid issues three years ago and gained weight due to that. Trying Phen again and this is day two. Hot and cold flashes, cold hands and feet as well as headache and insomnia. Restless energy with anxiety but waiting a few days to see if I adjust which most people do. How is everyone doing that started it this month?

I started taking the 37.5 dose of Phentermine a week ago. I went to see a weight loss specialist and he wrote the prescription. He said for the first few days or as long as you have to, to get used to the drug, take half a pill once a day on an empty stomach. He say to take it exactly 2 hours after eating breakfast. Well initially for the first 3 or 4 days I was fine. I'm not entirely sure how many pound I've lost because my scale at home would say one thing and the scale the gym another. But I always weigh first thing in the morning after using the bathroom. Well on 5th and 6th day, I noticed that my heart would beat really fast and I would be out of breath doing simple things like walking around, and I never had this problem before, even when I wasn't taking the drug. I was in the shower one night and I was soo weak that I almost passed out. I thought I was getting sick, because I heard myself wheezing and I couldn't stop coughing but its a side effects. In my personal opinion this drug is dangerous. And I'm not going to continue to ignore all the effects the drug has because I like the results I get while I'm on it. I have completely stopped taking since, I almost had to go to the hospital. I don't ever want to feel like that again.

I had a headache the first night I am on 30mg capsules and yes I am never hungry either but make sure u eat something and drink water i have cut out things that I used to eat. I don't go to gym or anything but I am up and active now I am not sleeping half the day . The headache is gone I did have a tingle sensation thru my whole body almost felt like I was drunk the first day. I think after my first 20 lbs are gone I will go to
Lower dose so I don't build a tolerance then loose 10 lbs that way and then get my additional 20
Lbs with the higher dose again . I will continue eatin right and hopefully keep te weight off . I don't have major side effects I took advil for my headache

That could be my problem...I was instructed to take it on an empty stomach, and while I do not consume caffeine, I do drink red wine pretty frequently. I will talk to my doctor, thanks for the advice!

@makalak, talk to your dr, but it sounds like it's either too high of a dose for your system, or it's not a delayed release pill. make sure you don't drink alcohol with it, do take food with it, and try to reduce caffeine or other energy boosting supplements, as that may be causing the effect you're experiencing.

My wife, for instance, is very sensitive to sugar, caffeine, phentermine, etc, so she always has to reduce her intake to 1/2 or even 1/4 of what I can handle. Sounds like a similar situation with yourself.

Additionally, make sure you're seeing a good physician to oversee your dosage. I recommend an "internist" (also labelled as a "doctor of internal medicine", often called a "doctor's doctor"). Internists are pretty much all-around specialists, and are better qualified for dealing with drugs such as phentermine than most doctors that have a limited specialization.

Good luck!

I started 15mg Phen for a week, and couldn't handle it. First few days were OK, but after day 5 I felt like I was on speed, my mood was uncontrollable, I was having panic attacks, and terrible insomnia. Not to mention weird sensations like chills, jitters, and really high heart rates when exercising. Do these side effects go away, should I just wait it out?

Thanks!
