You can take Tylenol (acetaminophen) every 4 to 6 hours as needed, but you must not exceed the maximum daily dose to avoid the risk of liver damage. For adults and teenagers:

• The typical dose is 650 to 1000 mg every 4 to 6 hours as needed

• For Tylenol Regular Strength (325 mg per tablet), the usual recommendation is 2 tablets every 4-6 hours, not exceeding 10 tablets (3250 mg) in 24 hours

• For Tylenol Extra Strength (500 mg per tablet), the dose is 2 tablets every 6 hours, with a maximum of 6 tablets (3000 mg) in 24 hours

• The absolute maximum daily dose generally should not exceed 4000 mg, but many experts recommend limiting to 3000 mg daily to be safer, especially if used regularly

• If you have liver disease, are underweight, elderly, or take other medications containing acetaminophen, you should consult your healthcare provider as your safe dose may be lower

For children:

• Dose is based on weight or age, and Tylenol can be given every 4 to 6 hours while symptoms last, but not more than 5 doses in 24 hours

• Always follow the specific dosing instructions on the product label or consult a pediatrician.

Additional precautions:

• Avoid taking multiple products containing acetaminophen simultaneously to prevent accidental overdose

• Do not use Tylenol for fever for more than 3 days or for pain for more than 10 days without medical supervision

• Avoid alcohol while taking Tylenol, as it increases risk of liver toxicity

In summary, for most adults, taking 2 tablets of Tylenol Regular Strength every 4-6 hours or 2 tablets of Extra Strength every 6 hours is standard, with a maximum daily dose of 3000-4000 mg depending on individual risk factors

. Always adhere to the product label and consult a healthcare professional if unsure.
