actually, these tablets you are taking are more closely related to acetametophine. which is tylenol. and might i suggest not listening to anyone but your primary care doctor, about dosaging, or combinations of medications. its a valiant effort to help, but only your doctor knows the potential risks of other medications you might be on that would normally contraindicate usage of other meds. and these other people offering suggestions have no clue about your past medical history.and as far as doubling up on the dosage, not wise. it is given as a recommendation from the manufacture for a reason. just because it says take no more than 8 in 12 hours doesn't mean take 8 at once for a 12 hour period.
