i am taking topomax for my migraines and i was told to try the generic. it didn't help. within 2 days i had migraines. 6 months later my pharmacist told me to take the clone which is manufactured by the same company and has the same ingredients in it just marketed with a different name, topolax so it would be cheaper, half the price. it is completely different to the generic which is marketed by a different company and contains different ingredients. so i tried it. no migraines, half the price.
