here's what i read about topamax (i'm on it too by the way; i take 50 mg twice a day, and it has worked wonders in terms of decreasing the frequency of my migraines!!!)...fortunately, i haven't had any serious or even mild side effects so far (that i can even speak of or feel)...
anyway, here it is:
"When Indicated for Migraine:
Since this is a relatively new way to use some of the newer neuronal stabilizers
(anticonvulsants) such as Topamax® (topiramate) (As well as others like Neurotin® (gabapentin), Lamictal® (lamotrigine) and Gabatril® (tiagabine)) prophylactically for Migraine disease, the dosage will be directed by your physican.
**The best results were achieved at a dosage of 100 or 200 milligrams of topiramate per day
**"The key to success with Topamax is a very slow titration up to the therapeutic dose. Patients should begin taking only 15 mg, once a day, and taper up slowly from there, being sure to take it in a split dose."
The effective dosages are lower than you might think. Many patients achieve good results at only 50 mg per day."
**Possible Side Effects:
Some side effects, such as fatigue, are more likely to surface with high doses of Topamax®. Others occur regardless of dosage. While many tend to disappear after the first 8 weeks of therapy, it's still important to report them to your doctor. Only your doctor can determine if it is safe for you to continue taking Topamax

Abdominal pain, abnormal coordination, abnormal vision, agitation, anxiety, appetite loss, back pain, breast pain, chest pain, confusion, constipation, depression, difficulty with concentration, difficulty with memory, dizziness, double vision, drowsiness, fatigue, flu-like symptoms, indigestion, involuntary eye movement, language problems, leg pain, loss of coordination, menstrual problems, mood problems, nausea, nervousness, rash, sinusitis, slowing of movements, sore throat, speech problems, tingling or burning sensations, tremors, upper respiratory infection, weakness, weight loss.

Topamax® has also been known to cause a number of very rare side effects (typically striking less than one person in a hundred). If you develop any unfamiliar problems while taking Topamax®, report them to your doctor.
Hope this helps a little...i know it's pretty long...sorry about that...but the more informed we are, the better we can advocate for ourselves!!!
Good luck and have a blessed day!
