Why is Acetaminophen prescribed?

Tylenol is a fever- and pain-reducing medication that is widely used to relieve simple headaches and muscle aches; the minor aches and pains associated with the common cold; backache; toothache; minor pain of arthritis; and menstrual cramps.

Most important fact about Acetaminophen

Do not use Tylenol to relieve pain for more than 10 days, or to reduce fever for more than 3 days unless your doctor has specifically told you to do so.

How should you take Acetaminophen?

Follow the dosing instructions on the label. Do not take more Tylenol than is recommended.

--If you miss a dose...

Take Acetaminophen only as needed.

--Storage instructions...

Store at room temperature. Protect extra strength gelcaps and geltabs from high humidity and excessive heat. Keep the extended relief caplets away from high heat.

What side effects may occur?

Tylenol is relatively free of side effects. Rarely, an allergic reaction may occur. If you develop any allergic symptoms such as rash, hives, swelling, or difficulty breathing, stop taking Tylenol immediately and notify your doctor.

Special warnings about Acetaminophen

Stop taking Tylenol and check with your doctor if you develop new symptoms, if redness or swelling are present, if pain gets worse or lasts more than 10 days, or if fever gets worse or lasts more than 3 days. Children's and Junior Strength Tylenol should not be used for more than 5 days for pain, or 3 days for fever.

If you generally drink 3 or more alcoholic beverages per day, check with your doctor about using Tylenol and other acetaminophen-containing products, and never take more than the recommended dosage. There is a possibility of damage to the liver when large amounts of alcohol and acetaminophen are combined.

Possible food and drug interactions when taking Acetaminophen

If Tylenol is taken with certain other drugs the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Tylenol with the following:

Alcohol
Cholestyramine (Questran)
Isoniazid (Nydrazid)
Nonsteroidal anti-inflammatory drugs such as Dolobid and Motrin
Oral Contraceptives
Phenytoin (Dilantin)
Warfarin (Coumadin)
Zidovudine (Retrovir)

Tylenol should not be used with other products containing acetaminophen.
