Two extra strength ibuprofen are not a problem.
Just don`t do it again.
Dring a lot of water or fruit juice and take Vitamin C.
If it was Tylenol,
that is a problem.
Call your doctor,
or the pharmacist and ask.
in the mean time.
Take 1000 mg Vitamin C and a lot of orange juice every hour,
this will help your liver detoxify the tylenol.
Do this immediately.
If you can get cranberry juice,
natural without artificial sweetners or sugar,
take a lot of that too.
You find that at health food sections of stores or health stores.
Let me know how you make out.
