most helpful answer i don't know anything about your medical history to give you an "okay". certain types of cancer especially those that may involve the liver and certain types of chemotherapeutic drugs that can cause liver effects may not permit acetaminophen use. because your chemotherapy is soooooo important it would be wise to ask this very patient-specific question directly to your oncologist. don't take acetaminophen until you get the specific "okay" from your oncologist.
can i take tylenol when having chemo?
