What is Dologesic?

Acetaminophen is a medicine that helps relieve pain and reduce fever.

Phenyltoloxamine is an antihistamine that helps lessen the effects of histamine in the body. Histamine can cause symptoms like sneezing, itching, watery eyes, and a runny nose.

Dologesic is a combination medicine used to treat fever, headache, menstrual pain, and other minor aches and pains. Dologesic also helps with itchy or watery eyes, and pain or fever caused by the common cold or seasonal allergies.

Dologesic may also be used for other reasons not mentioned in this medication guide.

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.

The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.

Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen, and can increase certain side effects of phenyltoloxamine.

Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking 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.

Dologesic may cause blurred vision or impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
