Tylenol (Acetaminophen) 500mg is an over-the-counter (OTC) medication commonly used to:

• Relieve mild to moderate pain, such as headaches, muscle aches, arthritis, backaches, toothaches, and menstrual cramps

• Reduce fever

How it Works

Acetaminophen works by blocking chemical messengers in the brain that signal pain and by affecting the area of the brain that regulates body temperature. Unlike NSAIDs (like ibuprofen or aspirin), it does not reduce inflammation.

Dosage

• Standard strength: 325 mg per tablet

• Extra Strength Tylenol: 500 mg per tablet

• Maximum adult dose:

  • 4,000 mg per day is the absolute limit

  • Many experts recommend staying under 3,000 mg/day to avoid liver damage

Dosing example (500 mg tablets):

• 1–2 tablets every 4–6 hours as needed

• Do not exceed 8 tablets (4,000 mg) in 24 hours

Warnings & Side Effects

Tylenol is generally safe when taken as directed, but overuse or high doses can cause serious liver damage. Watch out for:

• Nausea

• Loss of appetite

• Fatigue or weakness

• Yellowing of the skin or eyes (signs of liver trouble)

Avoid alcohol while taking acetaminophen, as it increases liver strain.

Safe Use Tips

• Check labels on cold/flu or pain relief products—many contain acetaminophen

• Don’t mix multiple products with acetaminophen unless approved by a doctor

• Safe for most people, including those with stomach issues or on blood thinners (but always consult your doc if unsure)
