Welcome to AN, I see you just joined today. Are you a student? LPN or RN & is this your first semester? Are you taking pharmacology currently? Analgesics can be given ORALLY which is the primary route. Aspirin is contraindicated in children due to Reye's Syndrome but is used in adults in low dose for cardiac reasons to prevent the platelet aggregation. Tylenol is a brand name, acetaminophen is generic name, but APAP is also an abbreviation for same med. There are many NSAIDS, what does your book or google list?
