Phentermine Anyone Have Strange Side Effects? (Page 3) (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 taken them for a while now under doctors orders ,
but I have learned a few things.After i was 230 pounds now down to 167 just few months I wouldnt go hungry,

well after the pill wore off I would be lightheaded ,so right before I took it I would eat something and drink tons and tons of water
.
Then after that wait an hour and take the pill .Never take them to late though and when I say early I mean I take one at 6am then the other at 12pm so it gives it time and by night I can sleep.

Also make sure when you take them dont sit around the pill gives you energy so thats when I will clean house walk ect..

Other then that I have been fine I dont drink tea or soda to much sugar that will not help with the extra energy.

Oh and the one Im takeing is Phentermine HCL 30mg twice a day with my doctors orders

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 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..

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.

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!

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.

When I started taking the pill my dr advised me to take 1/2 a pill for the first week to 10 days, then to start taking a whole pill. She also said to take it for 4-5 days then go off it for 2-3 days. There's still days that I only take 1/2 a pill. I've been on them since April, I think, and the first couple months I had side effects but none like you're describing. I had awful sweating, and some trouble sleeping but that's about it. I could not imagine taking a whole pill from day one, I would've been crawling the walls, and I'm a caffeine junky!

I took this pill a couple of years ago before my daughter was born and lost 30 lbs in 4 months. For me, 4 months is the longest the pill would work. It starts to lose its effectiveness after that. If you are trying to drop weight quickly for an event like HS Reunion or Wedding then this is the perfect solution! You have to go to your doctor to get this pill, I would not recommend getting online as it is very expensive and there are no guarantees that what your getting is actually phentermine. All I had to pay was my copay of $25 at the doctors office then the pills were $28 for a 30 day supply at Kroger. If you order online from some random website, its like hundreds of dollars - its cheaper just to go to your doctor to get the prescription, plus then you know your actually getting the real thing. My one complaint was the dry mouth but that is the only side effect I had initially. I had a baby last year and gained all the weight back and am up to 235 lbs. So I started taking this pill again on 9/12 and have lost 7 lbs so far as of this morning. I am hoping to get down to atleast 200 or under would be wonderful! I am also Hypothyroid so its almost impossible to lose weight on your own and for me this has been a miracle pill. This time around taking it I am feeling a "weird" sensation that everyone has been talking about - jittery, lightheaded, drowsy. I do not have any extra energy that everyone is talking about - I can still take a nap in the middle of the day but I do have some insomnia which I hope goes away in a few days. If you can get past the dry mouth and jittery feeling, then you will lose weight. You will lose weight even without exercising but I recommend exercising at least 30 minutes a day which will speed up the weight loss. Once you see the pounds come off, then it will motivate you to want to exercise more and eat better. After only 1 week my stomach has shrunk and I can only eat half of what I was eating before. The first time I was on this pill, I was also doing the Atkins Diet which I highly recommend. I am doing Atkins again this time as well but its tough! Good luck everyone!

You take 2 whole ones a day? That's why you feel like you're having a heart attack! I would be willing to bet that's why you have some of the other side effects also. I took 1 1/2 once and I thought I was having a heart attack. One just wasn't working so I thought I'd try 1 1/2. Bad idea. Took a week off from taking it then went back to my normal of taking it for 3-4 days then going off it for 2-3 days and haven't had any more issues. Been on it for 6-7 months and the first 2 months were the roughest as far as side effects. Seriously though, I would not take 2 a day, that's a good way to have a heart attack! Just my opinion though.

I was instructed to take one half of the 37.5 blue speckled tab daily...along with 200 mcg of chromium piclinate each day. The M.D. said I could just take B-12 tablet every day instead of coming in for shot every two weeks or whatever. The M.D. was two hours from where I lived. My sister in law and her son in law both melted away on program. I said...I'm going where you went and am going to do what you did. That's why I had to drive two hours : ) I was instructed...no cars/loading up the first two days; after two days could re-introduce carbs...about 75% less then I had been consuming; protein was 4oz to 6oz each of three meals. I would bring those fiber/protein breakfast bars with me...and only one in between meals if I was hungry and only one fruit per day. Very very important...8 glasses of water a day. Within a couple of days I was loosing about a pound per day. I went from a snug 40" and 230 lbs down to a 33" and 175 lbs within five weeks...and without any side effects...except for having to buy a new pair of jeans about every two weeks : ) I kept the weight off...stayed around 185 ish for quite a while. I'm getting ready to start the program again...and I know I will do good again. Water water water...and only 1/2 a tab...was probably doing 1,200 to 1,500 caleries per day...and did a lot of walking. By the way...I was semi homeless at that time...I was eating all my meals at McD's and TacoBell...really...no sodas, french fries...would have an apple pie once in a while. I am also semi disables, too....but nobody can really tell I am...I also take other nutritional supplements not. I'm 63...no grey hair...and still have hair : ) am told I look like I'm in my 40's or early 50's...each day I'm doing better and better...have a business I'm launching in S. F. Don't be afraid to use this...just do it because you want to be healthier and happier...Good Health To You and Yours : )

It has been a rough start but I'm glad I'm going in the right direction!

Oh yes. Crazy libido surge! At least for me. And yes on the increased wetness. And I'm female if you weren't sure by my screen name. lol.
I also get a very dry mouth at times. Funny that I have no fluid in my mouth but apparently it all goes down below. Go figure! Lol. Sometimes I also get a a bit hot and a sheen of sweat breaks out. Not a lot, just sheen all over my forearms (is where I notice it most and sometimes forehead) and then it disappears.
