t notice any change within 3 months, or any reduction of side-effects, you may want to try another medication. But, I was on
Topamax for about 2 years, and
for me the side-effects went away in the first year but did persist longer than 3 months... so although 3 months should be a good indicator, it is not always the case either. Still, if you find the side-effects to be disruptive, disabling, or you cannot tolerate them, then you may want to try explaining that to your doctor again.
