acetaminophen (rectal) (cont.)

What should I discuss with my healthcare provider before using acetaminophen (Acephen, Feverall, Mapap, Uniserts)?

You should not use acetaminophen if you are allergic to it.

Do not use this medication without a doctor's advice if you have ever had alcoholic liver disease (cirrhosis) or if you drink more than 3 alcoholic beverages per day. You may not be able to use acetaminophen.

Ask a doctor or pharmacist if it is safe for you to use acetaminophen if you have:

  • liver disease; or
  • a history of alcoholism.

It is not known whether acetaminophen will harm an unborn baby. Before using acetaminophen, tell your doctor if you are pregnant.

Acetaminophen can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

How should I use acetaminophen (Acephen, Feverall, Mapap, Uniserts)?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Do not use more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death.

One acetaminophen suppository may contain up to 650 mg of acetaminophen. Know the amount of acetaminophen in the specific product you are using.

If you are treating a child, use a pediatric form of acetaminophen. Carefully follow the dosing directions on the medicine label. Do not give the medication to a child younger than 2 years old without the advice of a doctor.

Do not take an acetaminophen rectal suppository by mouth. It is for use only in your rectum.

Wash your hands before and after inserting the suppository.

Try to empty your bowel and bladder just before using the acetaminophen suppository.

Remove the outer wrapper from the suppository before inserting it. Avoid handling the suppository too long or it will melt in your hands.

For best results from the suppository, lie down and insert the suppository pointed tip first into the rectum. Hold in the suppository for a few minutes. It will melt quickly once inserted and you should feel little or no discomfort while holding it in. Avoid using the bathroom just after inserting the suppository.

Stop using acetaminophen and call your doctor if:

  • you still have a fever after 3 days of use;
  • you still have pain after 10 days of use (or 5 days if treating a child);
  • you have a sore throat, high fever, or nausea and vomiting;
  • you have a skin rash, ongoing headache, or any redness or swelling; or
  • if your symptoms get worse, or if you have any new symptoms.

Acetaminophen can cause false results with certain lab tests for glucose (sugar) in the urine. Talk to your doctor if you are diabetic and you notice changes in your glucose levels during treatment.

The rectal suppositories may also be stored in the refrigerator. Do not allow the medicine to freeze.

Store at room temperature away from heat and moisture.
