Acetaminophen (Oral Route, Rectal Route)

Proper Use

Drug information provided by: Merative, Micromedex®

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. Liver damage can occur if large amounts of acetaminophen are taken for a long time.

If you are taking this medicine without the advice of your doctor, carefully read the package label and follow the dosing instructions. Talk to your doctor if you have any questions.

Carefully check the labels of all other medicines you are using, because they may also contain acetaminophen. It is not safe to use more than 4 grams (4,000 milligrams) of acetaminophen in one day (24 hours), as this may increase the risk for serious liver problems. For Tylenol® Extra Strength, the maximum dose is 3,000 milligrams per 24 hours.

You may take this medicine with or without food.

For patients using the oral liquid with syringe (e.g. Little Fevers®):

• Shake the bottle well before each use.
• Measure the dose with the provided dose syringe (e.g., AccuSafe™) that comes with the package. Do not use any other syringe, dropper, spoon, or dosing device when giving this medicine to your child.
• Remove the cap, attach the syringe to the flow restrictor, and invert the bottle.
• Pull back the syringe until filled with the dose prescribed by your doctor.
• Slowly give the medicine into your child's mouth (towards the inner cheek).

• Eat the acetaminophen granules along with the food.

For patients using acetaminophen oral powders (e.g., Feverall® Sprinkle Caps [Children's or Junior Strength]):

• Drink the medicine along with the liquid. You may drink more liquid after taking the medicine.

For patients using acetaminophen suppositories:

• If the suppository is too soft to insert, chill it in the refrigerator for 30 minutes or run cold water over it before removing the foil wrapper.
• To insert the suppository:
  • Remove the foil wrapper and moisten the suppository with cold water.
  • Lie down on your side and use your finger to push the suppository up into the rectum.
