I am on my 6th day of topamax and honestly it has been workign wonders and I have no side effects.....however maybe one. 1 day before I started topamax i got a uti so i was on meds for that and it hasnt gone away yet..its been 7 days and I am on my 3rd round of antbitiocs for it. All 3 doctors have told me its not due to topamax at all that its a very rare side effect and told me to keep on taking my 25mg of toapmax (very small dose). My uti is not hurting either. I am just peeing a lot and its incomfortable and burns. Please dear god tell me that if this is a side effect of topamax that it will go away with time as my body gets used to ti??????? I drink liek liters of water, take cranberry tablets too. = ( Topamax was my only hope. Neurontin and Elavil = big weight gain.
