Is fiorcet ok for migranes?

Yes. Even though it has fda approval for tension headaches, it can also be used for migraine ha. Not my first choice. Imitrex (sumatriptan) is more effective.
Severe Headache. You must first find out if you have true migraines, because the treatment is very different. Most people incorrectly believe that a real bad headache is a "migraine". Not so! a migraine is a specific central nervous system originating ha where most (85%) of headaches, even bad ones, come out of the neck. Untreated, simple ha can lead to "secondary migraines" with migraine-type features.
