Uses for meclofenamate

Meclofenamate is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce fever, relieve mild to moderate pain or symptoms of arthritis (eg, juvenile arthritis, osteoarthritis, rheumatoid arthritis), or treat menstrual pain or bleeding. It is also used to relieve the symptoms of ankylosing spondylitis, painful shoulder (eg, acute subacromial bursitis, supraspinatus tendinitis), or gouty arthritis.

Meclofenamate is available only with your doctor's prescription.

Before using meclofenamate

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For meclofenamate, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to meclofenamate or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of meclofenamate in children younger than 14 years of age. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of meclofenamate in the elderly. However, elderly patients are more likely to have age-related kidney, stomach, or bowel problems, which may require caution and an adjustment in the dose for patients receiving meclofenamate.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking meclofenamate, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Precautions while using meclofenamate

Using meclofenamate during the later part of pregnancy can harm your unborn baby. If you think you have become pregnant while using the medicine, tell your doctor right away.

Meclofenamate may increase your risk of having blood clots, heart attack, or stroke. This is more likely in people who already have heart or blood vessel disease. People who use meclofenamate for a long time might also have a higher risk. Check with your doctor right away if you have swelling and pain in your arms, legs, or stomach, chest pain, trouble breathing, loss of sensation, confusion, or problems with muscle control or speech.

Meclofenamate may cause bleeding, perforation, or ulcers in your stomach or bowels.

Check with your doctor right away if you have bloody urine, a decrease in frequency or amount of urine, an increase in blood pressure, increased thirst, loss of appetite, lower back or side pain, nausea, swelling of the face, fingers, or lower legs, trouble breathing, unusual tiredness or weakness, vomiting, or weight gain. These could be symptoms of a serious kidney problem.

Meclofenamate may cause a serious type of allergic reaction called anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing or swallowing, or any swelling of your hands, face, or mouth while you are using meclofenamate.

Serious skin reactions, including Stevens-Johnson syndrome, exfoliative dermatitis, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS) can occur during treatment with meclofenamate. Check with your doctor right away if you have blistering, peeling, or loosening of the skin, chest pain, chills, cough, diarrhea, fever, itching, joint or muscle pain, painful or difficult urination, red skin lesions, sore throat, sores ulcers, white spots in the mouth or on the lips, swollen glands, unusual bleeding or bruising, or unusual tiredness or weakness.

Meclofenamate can cause worsening of your heart failure. Check with your doctor right away if you have chest pain, decreased urine output, dilated neck veins, extreme fatigue, irregular breathing, irregular heartbeat, swelling of the face, fingers, feet, or lower legs, tightness in the chest, trouble breathing, or weight gain.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
