Hi my name is Shannon. I have been having cluster headaches and have a history of eplsiey and the doctor said to take the following medications topiramate 25 mg tablet and sumatriptan 50 mg tablet Commonly known as: Imitrex. I emailed and said in a not so nice away no fucken way these medications causes too many side effects. What is your opinion on how to handle this doctor. I also emailed my pcp doctor about this issue.
