Meclofenamate is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat fever or mild to moderate pain in adults. Meclofenamate is also used to relieve symptoms of osteoarthritis or rheumatoid arthritis in adults, and juvenile arthritis in children who are at least 14 years old.

Meclofenamate is also used to treat menstrual pain or heavy menstrual bleeding.

Meclofenamate is sometimes used long-term to treat symptoms of ankylosing spondylitis, gouty arthritis, or shoulder pain caused by bursitis or tendinitis.

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

Meclofenamate 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).

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

You should not use meclofenamate 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;
• liver or kidney disease;
• asthma; or
• fluid retention.

If you are pregnant, you should not take meclofenamate unless your doctor tells you to. Taking an NSAID during the last 20 weeks of pregnancy can cause serious heart or kidney problems in the unborn baby and possible complications with your pregnancy.

Tell your doctor if you are breastfeeding.

Meclofenamate is not approved for use by anyone younger than 14 years old.

Use Meclomen (Oral) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Get emergency medical help if you have signs of an allergic reaction (sneezing, runny or stuffy nose, hives, wheezing or trouble 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, feeling short of breath.

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

• a skin rash, no matter how mild;
• shortness of breath (even with mild exertion);
• swelling or rapid weight gain;
• nausea, diarrhea, flu-like symptoms (fever, swollen glands, muscle aches, severe weakness);
• signs of stomach bleeding--bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;
• liver problems--loss of appetite, stomach pain (upper right side), tiredness, itching, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
• kidney problems--little or no urination, swelling in your feet or ankles, feeling tired or short of breath; o
• low red blood cells (anemia)--pale skin, unusual tiredness, feeling light-headed or short of breath, cold hands and feet.

Older adults may be more likely to have symptoms of stomach bleeding.

Common side effects may include:

• indigestion, stomach pain, nausea;
• diarrhea, constipation; or
• dizziness.

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.

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

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