Can my medicine make me gain weight?

I have been on accutane for a month and a half.  I have also put on 12 pounds in that month and a half.  I have read about the side affects of accutane and none of them state weight gain- it is more on the weight lose side.  The weight seems to be in my mid-section.  Could this weight gain be from my medicine? 

I honeslty don't know anything about Accutane, but I started on Prozac and BC at the same time and gained 30 pounds. My doctor told me that while medicine will not make you gain weight because weight gain is calories in vs calories out, meds can make you hungrier. I would not be surprised if there is something more to it (like water retention or something), but I definitely agree that something happened that I ate a lot. My weight gain was also mostly in my middle, which is odd because I have never had midsection problems and have always had a flat stomach. I guess you can only gain so much before the weight ends up there too though. I quit my Prozac in May because I didn't need it anymore and have lost 20 pounds (dieting of course, but that was next to impossible before). So you tell me. :)

You should probably ask your doctor. And keep a strict log of what you eat. If you notice yourself getting hungry, eat something low calorie but filling, but keep it tracked too.

Accutane shouldn't cause weight gain like that, from what I've heard. I just started on it about 2 weeks ago myself, so I've been researching it a bit. That's a lot of weight to put on that suddenly at 2 pounds per week, so I'd bring it up with a doctor regardless of whether it's the accutane or not.

You also don't say whether you're male or female, but if you're female and recently started on birth control pills just before starting the accutane, sometimes those cause some weight fluctuations, especially for the first few months, either due to actual weight gain, or to changes in body water composition.

Some people act differently from others. Some meds do the same. We are not all alike and even though the Dr. might say it shouldn't happen, you know better than that.  If you started gianing weight after starting the meds then the meds have had an effect on you.  You may taper off, you may continue to gain, keep an eye on it, if you gain some more, increase your activity to help dissipate the weight.  Some meds slow you down, lethargic etc. which I think affects the metabolism.  So, beef up your exercise, lower your salt, stay on your diet drink more water.  Nip it in the bud.

I do not believe that doctor who said meds will not make you gain weight, but will only make you hungrier.  BUNK. BUNK. BUNK. I gained 25 pounds on SSRI antidepressants.  No change in eating habits.  Lost 20 of it very swiftly about eight months after I stopped taking Lexapro (15 years on SSRI antidepressants, I might add).  No change in eating habits. Now I take Wellbutrin which operates with different chemicals. I still need to lose ten - fifteen pounds, but I don't think that's Wellbutrin's fault.

Have a friend who was on Accutane and gained.  Changed meds and lost the weight.  Doesn't effect everyone that way, but sure is a possibility.
