Migraine
"I first started using Frova 4 1/2 years ago. It was wonderful and a great replacement for the Imitrex that no longer worked and had some side effects. Now I am having rebound headaches. I can guarantee I will have another migraine at almost exactly the 24 hour mark from the time I last took Frova. Have switched back to Imitrex and it is doing the job."
