Phentermine Anyone Have Strange Side Effects? (Page 3)

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 :)

This is day one for me, I am very pleased as I don't have the urge to munch on snack although I do still need to eat a meal. My strange side effect is very cold (ice cold) hands and feet.

WOW, that dose 3X a day is EXCESSIVELY HIGH. My Dr. started me on the 37.5mg 1 X a day and that is good for me. I take it at about 9:00 a.m. and it gives me energy all day, and I do not crave food at all. I have taken it for about 3 weeks and I know I have lost at least 15 pounds, I drink lots of water and am using the pills to help get in the habbit of eating less and healthier. I have been getting heart palpitations in the evening and my face feels hot, but during the day I feel great. I am surprised that I have those symptoms at night when the pill should be wearing off....BUT overall I am VERY happy w/ this drug b/c it's the first time that I am NOT fighting food cravings. I am very excited to lose the weight.

I have been taking phentermine 37.5 since October 20, 2012. I'm female, 5'4" and weighed 189 pounds. I was determined not to cross into 200. I am at 161 pounds now. A loss of 28 pounds in four months. I lost 17 in the first month. its been harder since then. I eat smart and exercise. I try to stay at 1200 calories or less. I didnt realize plain water was so important. ALL I ever drink is unsweet tea. I love this pill. But it is a lifestyle change, not a miracle pill. My worst side effects have been icy cold hands and constipation. Until now. I have become easily irritated and able to cry in a second. I truly am easygoing and havent cried 2 times in the last 5 years, until now. I have cried every day. I plan on taking it one more month. But to me, the weight loss is worth having to cry through the next 11 pounds I lose! Nothing else has ever worked. I even skipped the month of December taking it because I had a little cold. i am being monitored by a doctor in 30 day supplies.

I think you have to go to a diet clinic where they check your BMI (Body Mass Index) and determine if you are overweight enough for a prescription

If you keep eating the same things that made you heavy before the pills then YES you will gain the weight right back.

If you are not ready to make better food choices during and after pill usage then that means that unfortunately you are just wasting your $$ and your weight loss will only be temporary.

It comes back on even if u eat right after u stop taking it? Because I changed my whole diet.

This medication is horrible, after six days I am quitting it. This is METH. Period. No wonder Meth is out of control in America. Not worth risking your health.

Hi everyone, my name is Destiny.
I lost 96lbs on 37.5mg phentermine, once a day.
After the year mark and it seems like now.. if I take it, I experience extreme side effects.

EXTREME anxiety. Ill get dizzy, light headed and my resting heartbeat (while setting still) is 115-130bpm.
More than that its hard to breathe (I think bcs my heart is racing) but its like im HUNGRY for air!! I will struggle to get a deep breath. scary stuff.

I want to get bck on phentermine and have tried (under dr care). but the side effects are just to much, scary.

I didnt have these side effects the entire year that I was on phen, it started after my 1yr check up. Idk if my body just hates the med now or what?. thoughts....

I took Phentermine many years ago and was able to lose a little over 40 pounds in 2 months. But then I had my youngest two children and I gained that weight back. I just started back on 37.5 about 2 months ago.I have lost 15 pounds and have no side effects. But the weight loss is not coming off as quickly as before. When I spoke to my doctor about it he suggested that I take it twice a day now. I just began that today. I will continue to take it until the doctor either stops it or I reach my goal. To me this is the answer to weight loss. I sincerely hope all of you having side effects will find they subside after awhile.

This is my second month of taking the 37.5's. I only have 2 complaints and neither are a big deal. My first is the sweating. OMG the sweating lol it's worse than hot flashes! Second is the lack of sleep. I'm up between 7:30-8 everyday and every night I'm awake in bed till 4am the earliest, but I'm never tired! My dr told me to take one a day for 4-5 days then go off it for 2-3 days. This seems to be working good for me. No headaches, no chills, bothers other than the two mentioned reasons. Does anyone else have an issue with the excessive sweating? I change shirts 2-3 times a day if not more. The sweat runs down my scalp, my back, legs , face. All over. It's so gross!

Yes sweating is a common side effect. My husband got that but luckily I dont. He stopped taking it because he would sweat and smell AWFUL right after a shower. Literally he would shower just before work on his lunch break and when he got home and he still smelled bad from sweat.

Me personally have not had this happen but im stopping it today from the other awful things its doing to me like racing heart dizzy/fainting spells and blurred vision. I was prescribed 37.5mg/day but only take half that every other day and cant handle it. Im going with straight up diet and exercise now.. im losing weight to be healthy and this is NOT healthy.

Good luck to you all

I was on my third week of this stuff last week and I have to say it really did help stop my appetite and I lost 9 pounds in THREE weeks!! HOWEVER... I could not stand up fast without feeling like I was going to pass out plus my vision would go black for a few seconds as soon as I stood up. I was super dehydrated! It was like I couldn't get enough water. I couldn't stop getting chills out of the blue for no reason. I was very constipated to the point where my stomach hurt so bad I wasn't sure if it was from not eating much b/c I never felt the urge to eat or b/c I hadn't went to the bathroom in a week?!?! I only have 14 more pounds to go. I really wish I could stay on it to help but it scares me and isn't worth feeling like I'm going to pass out...

My husband had same problem and the phentermine was he only medication he was on and only change he had made. He also had a lot of pain inhis testicles. It started around his 3Rd month. He quit taking them and within 48 hrs after symptoms subsided.

I just started taking this medication today. And I can say I have not been hungry at all. I really had to force myself to eat a sandwich bc I know going all day without food isn't good for you. I used to snack all the time. But I don't even feel the urge to eat anymore. But on the down side. I can't stop these hot flashes. I'm sweating like crazy. And constantly hot. But if that's the worst for weight loss then I guess it's worth it.
