What are acetaminophen tablets, caplets, or chewable tablets?

ACETAMINOPHEN (Tylenol®, Panadol®, Feverall® and many others) is used to relieve mild to moderate pain and reduce fever. It is the preferred treatment for patients with aspirin allergy, ulcers, or clotting (bleeding) disorders. Patients who are taking medicines to treat gout can safely take acetaminophen. There are many generic variations available for adults and children. Tablets can be plain, extended-release, or chewable. Gelcaps or geltabs are also available.

What should my health care professional know before I take acetaminophen?

They need to know if you have any of these conditions:

  • anemia
  • drink more than 3 alcohol-containing drinks per day
  • infection
  • kidney disease
  • liver disease
  • hepatitis
  • phenylketonuria
  • an unusual or allergic reaction to acetaminophen, aspirin, other medicines, foods, dyes or preservatives

How should I take this medicine?

Acetaminophen can be taken as needed for the relief of pain or fever, or may be prescribed by the prescriber or health care professional on a more regular basis. Do not take more often than directed, or more than the recommended dose. Acetaminophen tablets come in several strengths for children and adults. Make sure you are taking or giving the correct dose. Take acetaminophen tablets, caplets or gelcaps by mouth. Follow the directions on the label. Chewable tablets can be chewed before swallowing, crushed and taken with food, or mixed in a drink. Swallow extended-release tablets whole, do not crush or chew. Drink a full glass of water either with or after taking your medicine.

Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed. Do not administer adult acetaminophen preparations to children.

What if I miss a dose?

If your prescriber or health care professional has prescribed a regular schedule and you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

What drug(s) may interact with acetaminophen?

  • alcohol
  • medicines for seizures
  • antacids
  • cimetidine
  • medicines for mental problems and psychotic disturbances
  • warfarin

These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
