Acetaminophen, also called paracetamol or Tylenol, is the go-to over-the-counter medicine for pain and fever. It eases headaches, muscle aches, toothaches, and lowers fever without upsetting your stomach like some NSAIDs. That makes it useful for people who can’t take ibuprofen or aspirin.
Adults: typical OTC doses are 325–650 mg every 4–6 hours, or 1,000 mg every 6–8 hours when needed. Don’t go over the safest daily limit—most experts now recommend staying under 3,000 mg per day to cut liver risk. Some labels still list 4,000 mg as the absolute max, but lower limits are safer, especially if you drink alcohol or take other meds.
Children: dose by weight. Use 10–15 mg per kg per dose every 4–6 hours, with a max of about 75 mg/kg per day. Always use the dosing syringe or cup that comes with the product—household spoons are unreliable.
Alcohol and liver disease raise the risk of serious liver injury with acetaminophen. If you drink regularly or have liver problems, talk to a doctor before taking it. Mixing multiple medicines that contain acetaminophen (cold & flu products, prescription combos) can push you past the safe limit without realizing it—check labels carefully.
Interactions: acetaminophen can increase bleeding risk when combined with warfarin for some people. If you’re on blood thinners, ask your prescriber how to use it safely.
Overdose signs include nausea, vomiting, loss of appetite, abdominal pain, and yellowing skin or eyes. If you suspect an overdose, seek emergency care right away—antidote treatment works best when started early.
Pregnancy and breastfeeding: acetaminophen is generally considered safer than NSAIDs during pregnancy, but use the lowest effective dose for the shortest time and check with your healthcare provider.
When to pick something else: if you need anti-inflammatory effects (swelling from injury, some arthritis pain), ibuprofen or naproxen may work better. Those options can irritate the stomach and affect blood pressure, so weigh risks and benefits.
Practical tips: always read the active ingredient, keep a log if you take multiple meds, and use the smallest effective dose for the shortest period. Store medicines out of reach of children—accidental pediatric overdose is a common emergency.
