- if your symptoms get worse, or if you have any new symptoms.
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.
What happens if I miss a dose?
Since acetaminophen is used as needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of acetaminophen can be fatal.

What should I avoid while using acetaminophen?
Ask a doctor or pharmacist before using any other cold, allergy, pain, sleep medication, or a blood thinner ( warfarin, Coumadin, Jantoven). Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Using certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.
Avoid drinking alcohol. It may increase your risk of liver damage while using acetaminophen.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
