Wierd Side Effects?

**ricki0628** · April 28th, 2008, 04:21 PM

Hello! I just started Phen this past Friday, so I am 4 days in. I love the fact that I never feel hungry, but I am also having some wierd side effects and was wondering if anyone else experienced these in the beginning? I have had nausea, nervousness/anxiety, headache, fast heartbeat, and some shortness of breath. I called my Dr., but they haven't gotten back with me yet. I am on a pretty high dosage, (37.5 mg), so maybe that is why? Any help/suggestions/comments would be appreciated! Thanks!

They are all the side effects of the phentermine sweetie. I think you might have to cut it in half and take half in the morning, half in the afternoon. That might help lessen the effects.

try halfing your pill. only take half until you can see how it affects you. once your body is used to it, you will be able to take the whole pill. be sure to talk to your dr. he/she may even decide this isn't for you. so be sure to not miss that call

im taking the same dosage. i had the side effects also. but i was told (by the dr.) to make sure you are drinking plenty of water. that's usually your body telling you what it needs, also i found that because i wasn't hungry, i really wasn't eating. now i make myself eat 3meals and 3snacks, and drink tons of water, and im not having those problems.

I am sorry to hear that you are having such strong side effects. It can be uncomfortable and uneasy to experience those.

I have had some small side effects. I now have a dry mouth - cotton mouth! - and bad breathe! I will brush my teeth and rinse and still feel like my mouth stinks! I just keep mints on hand or gum.

One good side effect that I have noticed. Last week was PMS week for me and I always get so bloated and have mild to severe cramps. It's been like that my entire life. Well last week, first cycle while on phen - newbie here! - and I didn't have cramps or bloating. I even had a minimum of my usual mood swings. I can't say that it is because of phen, but something was different this month compared to the last 25 years!

I was on 30 mg and those r just the normal side effects. I had them too but the heart beat thing went away..then it came back and it was like an every day thing so I asked if i could go down to the 15mg and now I dont have the side effects any more..if u dont think u can handle the higher dose than go down to 30, it might be better for u

my jitters, insomnia, and racing heart all went away within 3 days. The only time it ever happens to me now is if I haven't had enough water.
I never really got the headaches everyone talks about.
Now I look back at those first few days and wish I could get that feeling again. My house was sparkling like Martha Stewart was here. I never sat down, I was like a mad woman! Now everything is back to normal. Ahhh, the good old days.

Thanks so much everyone for your help! My doctor called back and I can cut the pill in half, so I am going to try that for a while and see if it helps! It made me feel much better to know that others have experienced this too, though, and they are fine now! Thanks again! BTW-I weighed myself last night and I have already lost 6 lbs!!! Not bad for 5 days!

**WVMommyof2** · April 29th, 2008, 12:19 PM

Cutting in half should work, I'm glad your doctor got back to you. My side effects went away after a week. I still don't get hungry but I'm not racing around the house anymore, and I don't feel tired in the day anymore.

Ricki, I was reading your posts about your side effects. How long did your doctor say you should take the half pill?

**maggie953** · April 30th, 2008, 09:07 PM

I am also new, and have only been taking half a pill since I started. It controls my hunger but I am worried about the shortness of breath. I will try drinking more water, I know I have not be drinking enough......Thanks!

**ricki0628** · May 1st, 2008, 12:26 PM

Unfortinately, my Dr. told me to STOP taking Phentermine. The side effects just kept getting worse and they said that it was not safe for me to continue. I am sad because I was losing weight so fast, but taking a chance with my health wasn't worth it. Maggie, i would suggest talking to your dr. too, and seeing if you should continue.
I am going to talk to my dr. abut seeing if there is somethng else I should try. has anyone else had any luck with another drug? If so, I would be glad to hear about it!

**Cmarie123** · May 1st, 2008, 12:47 PM

Those are all normal for Phen. I agree, try taking 1/2 of the pill. That should help. The side effects will wear off in time.

**Gigalo78** · May 1st, 2008, 05:15 PM

I am BRAND SPANKIN' NEW to Phen. Today is my 2nd day and I really like the way it supresses my appetite to the point where I really don't over eat anymore. The one side effect that I noticed LAST NIGHT was the Insomnia. I usually CRASH&BURN as soon as I get home from work and working out.

But last night, I went to bed @ midnight and woke up @ 2:30am. WIDE AWAKE!!!
Couldn't go back to sleep for anything!

When I finally did, it was 5:30am. Although I had to wake up in an hour to start getting ready for work, I didn't have any trouble waking back up. Wierd. We'll see 2nite if its becoming an issue or not. Anyone else experience Insomnia?

One other side effect was constipation. I couldn't go at all yesterday. I felt so FULL and backed up..lol gross..but true. I am trying to drink ALOT more water to day to see if it will be easier.

**Loving Me** · May 1st, 2008, 07:37 PM

Yeah that's pretty normal. I started on April 18th and for the first 2-3 nights I could not sleep (thank GOODNESS that went away), now I am having the fast heartbeating, jitters every once and a while, bloated, constipation(which I hear is normal) and a HEADACHE from the time I take it the pill (7 a.m.) until 6 p.m. EVERY SINGLE DAY!!! I am assuming you take the good (rapid weight loss) with the bad and just try to mange the side effects the best way you know how. I am only on 30 mg so maybe you wanna go down some until your body becomes use to it. Good luck, the results are GREAT!

You have to make sure you drink lots of water when you are on this med. If you don't you will dehydrated very fast and it will cause headach and fast heart beat. Even though you may not feel hungry make sure you eat. I just started slim fast when i find that i can't eat and it helps a lot. take a daily vitamin also.
