What is the most important information I should know about diflunisal?

Diflunisal can increase your risk of fatal heart attack or stroke. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG). Diflunisal may also cause stomach or intestinal bleeding, which can be fatal.

What is diflunisal?

Diflunisal is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat mild to moderate pain, osteoarthritis, or rheumatoid arthritis.

Diflunisal may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking diflunisal?

Diflunisal can increase your risk of fatal heart attack or stroke, even if you don't have any risk factors. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Diflunisal may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using diflunisal, especially in older adults.

You should not use diflunisal if you are allergic to it, or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.

Tell your doctor if you have ever had:

  • heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;
  • a heart attack, stroke, or blood clot;
  • stomach ulcers or bleeding;
  • asthma;
  • fluid retention;
  • liver or kidney disease; or
  • if you take aspirin to prevent heart attack or stroke.

Taking diflunisal during the last 3 months of pregnancy may harm the unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

You should not breastfeed while using diflunisal.

Diflunisal is not approved for use by anyone younger than 12 years old. Ask a doctor before giving this medicine to a child or teenager with a fever, flu symptoms, or chicken pox.

How should I take diflunisal?

Follow all directions on your prescription label and read all medication guides. Use the lowest dose that is effective in treating your condition.

Swallow the tablet whole and do not crush, chew, or break it.

If you use this medicine long-term, you may need frequent medical tests.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using diflunisal.

Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Since diflunisal is used when needed, you may not be on a dosing schedule. Skip any missed dose if it's almost time for your next dose. Do not use two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include vomiting, diarrhea, gasping for breath, fast heart rate, sweating, confusion, extreme drowsiness, and fainting.

What should I avoid while taking diflunisal?

Ask a doctor or pharmacist before using other medicines for pain, fever, swelling, or cold/flu symptoms. They may contain ingredients similar to diflunisal (such as ibuprofen, ketoprofen, or naproxen).

Avoid taking aspirin unless your doctor tells you to.

Avoid drinking alcohol. It may increase your risk of stomach bleeding.

Ask your doctor before using an antacid, and use only the type your doctor recommends. Some antacids can make it harder for your body to absorb diflunisal.

What are the possible side effects of diflunisal?

Get emergency medical help if you have signs of an allergic reaction (hives, runny or stuffy nose, wheezing, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Get emergency medical help if you have signs of a heart attack or stroke: chest pain spreading to your jaw or shoulder, sudden numbness or weakness on one side of the body, slurred speech, swelling in your legs, feeling short of breath.

Stop using diflunisal and call your doctor at once if you have:

  • changes in your vision;
  • any skin rash, no matter how mild;
  • shortness of breath (even with mild exertion);
  • swelling or rapid weight gain;
  • signs of stomach bleeding --bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;

  • kidney problems --little or no urination, swelling in your feet or ankles, feeling tired; or
  • low red blood cells (anemia) --pale skin, unusual tiredness, feeling light-headed, cold hands and feet.

  • nausea, vomiting, stomach pain, indigestion;
  • diarrhea, constipation, gas;
  • dizziness, drowsiness, headache, tired feeling;
  • rash; or
  • ringing in your ears.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
