How to take it

Take Fortaz exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

The Fortaz dose your doctor recommends will be based on the following:

  • the condition being treated
  • other medical conditions you have
  • other medications you are taking
  • how you respond to this medication
  • your kidney function
  • your weight
  • your age

The recommended dose range for Fortaz is 500 mg to 6 grams, divided into even doses and given every 8, 12, 24, or 48 hours.

Warnings

Serious side effects have been reported with Fortaz including:

  • hypersensitivity (severe allergic reaction). Signs of a hypersensitivity reaction, which include the following:
    • chest pain
    • swelling of the face, eyes, lips, tongue, arms, or legs
    • difficulty breathing or swallowing
    • fainting
    • rash
  • diarrhea. Diarrhea is a common problem caused by antibiotics, and it usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken their last dose of the antibacterial. If diarrhea is severe or lasts more than 2 or 3 days, contact your doctor, as this may be a sign of an infection of the bowels.
  • superinfection. Fortaz should not be used for extended periods. Prolonged use can lead to the growth of dangerous organisms that are resistant or unresponsive to this medication. Take Fortaz for the duration prescribed by your doctor.
  • bleeding abnormalities. Your health care provider may want to monitor lab tests that show how well your blood is able to clot or that measure your tendency to bleed. Any abnormalities or irregularities that may occur may be more common in those with kidney dysfunction.
  • nervous system disturbances. Some may experience nervous symptom abnormalities such as a seizure or disturbances of consciousness (confusion, hallucinations, stupor, coma) when the dose of Fortaz exceeds the recommended dose, especially in the presence of kidney dysfunction.

Do not take Fortaz if you are allergic to Fortaz or to any of its ingredients.
