Flextra

Generic Name: acetaminophen/caffeine/phenyltoloxamine (ah-seet-ah-MIN-oh-fen/ka-FEEN/fen-ill-tole-OX-a-meen)
Brand Name: Flextra

Flextra 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. It may also be used for other conditions as determined by your doctor.

Flextra 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 Flextra if:

  • you are allergic to any ingredient in Flextra
  • you have lung problems (eg, asthma, emphysema, chronic obstructive pulmonary disease [COPD]), difficulty urinating due to an enlarged prostate, glaucoma, or blood clotting problems
  • you are taking medicine for blood clotting or sodium oxybate (GHB)

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

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.
  • Flextra 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.
  • Do not exceed the recommended dosage or take Flextra for longer than prescribed without checking with your doctor.
