text: is it safe to take tylenol and viagra at the same time? i love viagra.  the problem is the pounding headache i get a couple hours after taking it.  would it be all right to take some tylenol to prevent the headache when i take my viagra? first, try a lower dose of viagra (you can cut the pills in half). if that doesn't help, go ahead and take a couple tylenol, but wait about 30 minutes to an hour after taking the viagra.
