To insert an acetaminophen suppository into the rectum, follow these steps:
- Remove the wrapper.
- Dip the tip of the suppository in water.
- Lie down on your left side and raise your right knee to your chest. (A left-handed person should lie on the right side and raise the left knee.)
- Using your finger, insert the suppository into the rectum, about 1/2 to 1 inch (1.25 to 2.5 centimeters) in infants and children and 1 inch (2.5 centimeters) in adults. Hold it in place for a few moments.
- Stand up after about 15 minutes. Wash your hands thoroughly and resume your normal activities.
Stop taking acetaminophen and call your doctor if your symptoms get worse, you develop new or unexpected symptoms, including redness or swelling, your pain lasts for more than 10 days, or your fever gets worse or lasts more than 3 days. Also stop giving acetaminophen to your child and call your child’s doctor if your child develops new symptoms, including redness or swelling, or your child’s pain lasts for longer than 5 days, or fever get worse or lasts longer than 3 days.
Do not give acetaminophen to a child who has a sore throat that is severe or does not go away, or that occurs along with fever, headache, rash, nausea, or vomiting. Call the child’s doctor right away, because these symptoms may be signs of a more serious condition.
