What is Acuflex?

Acuflex contains a combination of acetaminophen and phenyltoloxamine. Acetaminophen is a pain reliever and a fever reducer. Phenyltoloxamine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Acuflex is used to treat runny nose, sneezing, and pain or fever caused by the common cold, flu, or seasonal allergies.

How should I take Acuflex?

Take Acuflex exactly as prescribed by your doctor. Do not take it in larger amounts or for longer than recommended. Follow the directions on your prescription label.

Call your doctor if your symptoms do not improve, or if you have a fever for longer than 3 days.

This medication can cause you to have unusual results with certain medical tests. Tell any doctor who treats you that you are taking Acuflex.

Warnings

Do not use Acuflex if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days. Serious, life-threatening side effects can occur if you take Acuflex before the MAO inhibitor has cleared from your body.

Acuflex can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Do not take more of this medication than is recommended. An overdose of acetaminophen can cause damage to your liver. If you drink more than three alcoholic beverages per day, do not take acetaminophen without your doctor's advice, and never take more than 2 grams (2000 mg) of acetaminophen per day.

Do not take Acuflex without your doctor's advice if you have ever had alcoholic liver disease (cirrhosis). You may not be able to take acetaminophen.
