and just like most otc remedies, ibuprofen can KILL! and if taken in less than death amounts, it'll destroy your liver. anything with tylenol/ibuprofen should be taken with extreme caution. the damage it causes is usally not immediate but it will build up quickly and unfortunately, we only have one liver apiece. even lortab and percoSETTE (vs percoDAN, which has aspirin instead of tylenol) should be avoided in large amounts.
