The appropriate Tylenol (acetaminophen) dosage depends on age, weight, and product strength.

For Adults:

• The typical dose is 2 tablets (usually 325 mg or 500 mg per tablet) every 4 to 6 hours as needed.
• Do not exceed 10 regular strength tablets (325 mg each) or the equivalent in other strengths within 24 hours.
• The maximum daily dose should not exceed 4,000 mg to avoid risk of severe liver damage.
• Some healthcare providers may recommend a lower maximum dose (e.g., 2,000 mg) for people with liver problems.
• Always take only one product containing acetaminophen at a time to avoid accidental overdose

For Children:

• Dosage is based on the child's weight and age.
• For example, children weighing 24–35 lbs might receive 5 mL of 160 mg/5 mL suspension every 4 hours as needed, not exceeding 5 doses in 24 hours.
• Use the dosing device provided with the product for accuracy.
• Do not use acetaminophen in infants under 12 weeks old without medical supervision.
• Follow specific pediatric dosing charts and consult a healthcare provider if unsure

Key Safety Points:

• Never exceed 4,000 mg per day in adults.
• Use only one acetaminophen-containing product at a time.
• Follow label directions carefully.
• Consult a healthcare professional if you have liver disease or other health concerns before taking Tylenol

In summary, adults can safely take up to 4,000 mg of Tylenol per day, usually 2 tablets every 4-6 hours, without exceeding 10 tablets in 24 hours. Children's doses vary by weight and should follow pediatric dosing guidelines closely.
