Does topamax cause weight gain?

My doctor prescribed Topamax to me, and I just started taking it. I'm a bit worried about side effects, especially weight gain. Does Topamax usually cause people to gain weight?

I was actually told it causes the opposite, but I feel like my weight is creeping up since I started it. Is anyone else experiencing weight gain on Topamax or is it just my anxiety playing tricks on me?

Usually, Topamax is known for weight loss, but body chemistry varies. Instead of spending money on expensive weight management programs right now, just track your daily food and plan a routine thyroid/hormone checkup to rule out other reasons.

Actually, clinical studies show that Topamax is much more commonly associated with weight loss due to appetite suppression. However, atypical metabolic reactions can happen. Consulting your prescribing physician is the best way to address this.

I totally get it, dealing with unexpected weight changes when you are already managing medical issues is so frustrating. While Topamax typically causes weight loss, a small percentage of people can have a different reaction. Do talk to your doctor about this.

I was just reading up on Topamax out of curiosity, and almost all medical literature lists weight loss as a very common side effect rather than weight gain. It apparently alters taste buds and reduces cravings for most users.
