Acuflex

Generic Name: acetaminophen/phenyltoloxamine (ah-seet-ah-MIN-oh-fen/fen-ill-tole-OX-a-meen)
Brand Name: Examples include Acuflex and Dologesic

Acuflex is used for:

Treating mild to moderate aches and pains associated with headache, muscle and joint soreness, backache, menstrual cramps, colds and flu, sinusitis, toothache, and minor pain from arthritis, and to reduce fever. It may also be used for other conditions as determined by your doctor.

Acuflex is an analgesic, antihistamine, and antipyretic combination. It works by blocking substances in the body that cause fever, pain, and inflammation. It also blocks histamine, which causes sneezing and itchy, watery eyes.

Do NOT use Acuflex if:

  • you are allergic to any ingredient in Acuflex
  • you are taking sodium oxybate (GHB)

Contact your doctor or health care provider right away if any of these apply to you.

Before using Acuflex:

Some medical conditions may interact with Acuflex. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have bleeding problems, blood vessel problems in the brain, a blockage of the stomach or bowel, a blockage of the bladder, or difficulty urinating
  • if you have lung problems (eg, asthma, emphysema, chronic obstructive pulmonary disease [COPD]), an enlarged prostate, glaucoma, kidney problems, or liver problems

Some MEDICINES MAY INTERACT with Acuflex. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Isoniazid, monoamine oxidase (MAO) inhibitors (eg, phenelzine), or sodium oxybate (GHB) because the risk of side effects may be increased
  • Anticoagulants (eg, warfarin) because the risk of side effects, including the risk of bruising or bleeding, may be increased

This may not be a complete list of all interactions that may occur. Ask your health care provider if Acuflex may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use Acuflex:

Use Acuflex as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Acuflex may be taken with or without food.
  • If you miss a dose of Acuflex and you are using it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Acuflex.

Important safety information:

  • Acuflex may cause drowsiness. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to Acuflex. Using Acuflex alone, with certain other medicines, or with alcohol may lessen your ability to drive or perform other potentially dangerous tasks.
  • Acuflex contains acetaminophen. Before you begin taking any new prescription or nonprescription medicine, read the ingredients to see if it also contains acetaminophen. If it does or if you are uncertain, contact your doctor or pharmacist.
  • Avoid taking medicines that cause drowsiness (eg, sedatives, tranquilizers) while taking Acuflex. Acuflex will add to the effects of alcohol and other depressants. Ask your pharmacist if you have questions about which medicines are depressants.
  • Do not exceed the recommended dosage or take Acuflex for longer than prescribed without checking with your doctor.
  • If you consume 3 or more alcohol-containing drinks every day, ask your doctor whether you should take Acuflex or other pain relievers/fever reducers. Acetaminophen may cause liver damage. Alcohol use combined with Acuflex may increase your risk for liver damage.
  • A very bad skin reaction (Stevens-Johnson syndrome/toxic epidermal necrolysis) may happen. It can cause very bad health problems that may not go away and sometimes death. Get medical help right away if you have signs like red, swollen, blistered, or peeling skin (with or without fever); red or irritated eyes; or sores in your mouth, throat, nose, or eyes.
  • If you are taking Acuflex for pain or fever and your symptoms do not improve within 10 days or if they become worse, check with your doctor.
  • Before you have any medical or dental treatments or surgery, tell the doctor or dentist that you are taking Acuflex.
  • Caution is advised when using Acuflex in CHILDREN because they may be more sensitive to its effects.
