Flunarizine by AA Pharma
How does this medication work? What will it do for me?
Flunarizine is used to prevent migraine headaches with or without aura (warning signs that occur before the headache begins). This medication should not be used for treatment of acute migraine headaches (headaches that have already started).
Flunarizine helps to reduce the frequency of migraine attacks and, to a lesser extent, the severity of the attacks. Flunarizine does not appear to have an effect on how long attacks last. The effect of flunarizine may not be seen for several weeks. Do not stop taking the medication due to lack of effect within the first six to eight weeks.
This medication may be available under multiple brand names and/or in several different forms.
