It seems from the history that you are having frequent headache because of migraine and you are on treatment with vasograin
The frequent headaches are because of recurrence of migraine and not because of vasograin. You require to use prophylactic drugs to prevent recurrent attacks of migraine headache
The commonly used drugs are flunarizine
or beta blockers like propranolol
. Hence I advice you to consult your doctor for prescription of drugs.
