Karen,
Your platelets are already low, and NSAIDs can increase the risk
for bleeding; imho,
acetaminophen over the
ibuprofen, hands down. With low platelets from tx and a compromised liver and kidney system, any of the NSAIDs are contra-indicated for you (includes Motrin, Advil, Aleve).
Tylenol is not to be taken indiscriminately either, though. With cirrhosis, no more than 2000 mg per day max (that means no more than 4 Extra Strength Tylenol in any 24 hour period).
