Phentermine Anyone Have Strange Side Effects? (Page 12) (Top voted first)

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 :)

I have been on Phen 15mg for two weeks now and my anger is so out of hand I felt like I was possessed. Called my doctor and he told me to take it every other day. So I stopped taking it for about 3 days and I just started again today with therapy and so far,criss cross applesauce,I'm doing fine on it. I am actually much happier now than when I first started two weeks ago. I've lost about 5 pounds since taking it so far. So with my thyroid condition and not being able to lose weight one bit for the last 2 years,I'm happy with my 5 pound weight loss. I'm looking to lose 100 pounds but my doctor said that when this is done(3months)then he's switching to me a med that I can take regularly for like a year or so. So I'm pretty happy about this. I love Phen. Just not when it makes me act like the devil.

I've been taking the 37.5 for almost a week now. So far no major complaints. Shortly after I take the pill I sweat quite a bit which is ok. My mouth stays dry which helps me remember to drink. My libido has increased which is fantastic. So far I'm doing OK with this pill. Looking forward to seeing if the lbs will begin to fall off. Started this on 8-21-15 @252 lbs currently on 8-26-15 I'm at 246 lbs but I range from 244-250 lbs without the pill. My goal is to get to at least 170 and at most 140. Thats the weight I was pre baby pre depo n pre zoloft.

I was on a 3 month MD supervised weight loss program and started at 195 lbs. I was prescribed 37.5 mg once a day. By the 3rd week I had already started to build a tolerance and the weight loss was much less. A PA told me that some other patients were taking up to 4 of these per day. So I took a risk and entered a 2nd weight loss program somewhere else to get extra dosage, working my way up to 1.5' then 2, then finally 2.5 in the 3rd month. I also took brief breaks of 1 or 2 days each week.

I'm not recommending that anyone do this. I'm just telling you what i did. It is important to monitor blood pressure while doing this.

Side effects were mainly dry mouth, which also reminded me to hydrate. Constipation was reduced with miralax. There was occasional insomnia which i treated with unisom or ambien. Also I found that alcohol consumption along with phentermine increased anxiety and should be avoided. A valium or xanax will reduce whatever anxiety the pill gives you, but as I got accustomed to the pill, nothing was needed.

The final weight loss was 20 lbs. I took 1 month off and started again, but I reached tolerance quicker, by the 3rd day. If I do this again, I'll wait several months.

I know I took risks, but the upside is that the weight loss lowered my blood pressure to a healthy level and allows me to exercise more intensely.

You might want to consider taking Belviq and Phentermine together and not put yourself at such risk.

Really wanted to lose some weight but mainly to get healthy and feel good. Well taking phen did not make me feel good.
And it did not take my appetite away. Got very dizzy, blood pressure very low, started to be unable to sleep well at night and just generally did not fell well so I have decided to stop taking it and just use extreme will power. Whats the point if I'm doing this to feel good and I feel lousy on this pill. I am determined this time so I know I will loose some weight but I am disappointed.

I am on day 7 with a 37.5mg dose and I have the worst headaches right around 6pm every day. I have taken Tylenol, ibuprofen, migraine medication and nothing gets the pain away. I have a 32oz water bottle that I refill at least 4 times daily, which puts me at around 128oz water intake daily and I still get the killer headaches. How am I suppose to exercise when I'm in constant pain??? Not working so far for me. Too much pain to handle.

Lol.. Don't ever take at once? You're joking right??? Been on this for a while like 3 months and I always take all of the pill (as per the does age instructions) at 530am.

Sounds like you didn't go through a licensed pharmacy, am I right? If so, these symptoms are identical to those of Strattera, an ADHD drug that is used by foreign countries to make fake phentermine. Phentermine is an amphetamine that gives you energy and kills appetite. Strattera makes you sleepy and leak semen. Expired Strattera is used to make a lot of so-called phentermine. Fake brands include Qualis Pharmaceutical, which does not exist.

I started taking this today, An hour and a half after taking I was having shortness of breath and it felt like my throat was closing in. I went to the er and it was determined that I was having an anxiety attack. Tonight, 8 hours after taking this medicine I have a horrible headache. Just waiting to see what tonight holds if I am able to fall asleep. After speaking to my dr, he suggested my pill get's cut in 1/4's to see what that will do for the time being. Honestly after today I'm feeling kind of scare and not sure I want to continue. Has anyone ever had this happen?

Stumbled across your post, with hopes to find I wasn't the only one to share the same side effects you had on Phen. I get very dizzy as well, and feel like I could fall over, so low blood pressure, the only difference is I have absolutely zero appetite on it. I could go days without eating. I do eat enough to sustain me but once I take then pill that day, no more food. It makes my throat feel right down into my esophagus. It's disappointing to see so many results people have but the way I feel on it just as you described why take it if it makes me feel this way, I'm trying the will power too. It's not as helpful, sometimes I give in and take one. Good luck to you.

You're only supposed to take it for 3 months at a time! Then you need a break.

Hi.. Phentermine also relaxes tense muscles..this sounds like caffeine OD or withdrawal or sugar withdrawal from diet change.. Also what I found is that during your time on this go to a chiropractor and or massage therapists to reset your musculoskeletal system..sometimes when you finally relax it offsets your system and it needs to be adjusted and relengthened..the headache is usually caused by these things on top of PNS system protections.. It is temp. Lower dose until adjusted if you need to..your dr. will agree..

MizzDrieka- yes I agree on Phen giving you crazy high libido. Me too. And very intense climax. Actually, when I get turned on, which takes nothing these days, it seems any extra hydration is in my nether regions. No lubricant needed! In fact its at the point where I think its too much. Whereas I get a dry mouth late in the afternoon. Go figure! Lol

I've been taking phentermine for about 3 years on and off. I am currently taking it and I just recently started getting light headed and dizzy on almost a daily basis. I went to the eye doctor and he adjusted my prescription that was too strong and told me to come back in a week to see how I was doing. It seemed to have helped slightly. I've also been diagnosed with migraines and vertigo by my doctor. I've been an overall healthy person. However my most recent symptom is feeling like me body is tingling all over. I can only feel it when I'm sitting still. If I'm walking, running, going up steps or doing anything else I don't even feel it. My husband says I need to stop taking it asap and give my body a break. I just hope it's not a more serious medical condition like MS or brain tumor. Has anyone else experienced these conditions? I've had different symptoms pop up on and off since about January/February of this year. I'm extremely stressed out at my job as well as from constantly googling what's going on (I know my husband tells me not to do that) and seeing the results that pop up.

I've been taking these over the last few years and always found I got those symptoms when I hadn't eaten, if you eat and drink water regularly you won't get headaches and symptoms like that, the tingly head etc does pass after a week or so, I don't get anything like that anymore but I must say I have come to a standstill on the weight loss, lost a stone and 4lb in the first 3 months and now nothing for the last 2 months, I don't put on which is a good thing but I just want to lose the last 5lb!
