Hello again, Another question for you. Do any of you know if extra strength Tylenol is safe to take if you are taking Acetazolamide? I take 250mg once daily. I also have Ativan 1mg that I take on very rare occasion when an attack is coming on. I've heard somewhere that some common shelf items are not compatable with Acetazolamide!? I have a headache and would like to take a Tylenol, but am a little concerned about doing so. Blessings 2 U all, MamaBear
