MEFENAMIC ACID - ORAL

(meff-en-AM-ick)

COMMON BRAND NAME(S): Ponstel

WARNING: Nonsteroidal anti-inflammatory drugs (including mefenamic acid) may rarely increase the risk for a (sometimes fatal) heart attack or stroke. This effect does not apply to low-dose aspirin. (See Drug Interactions section.) The risk may be greater in people with heart disease or increased risk for heart disease (e.g., due to high blood pressure, diabetes), or with longer use. This drug should not be taken right before or after heart bypass surgery (CABG). Also, this drug may infrequently cause serious (rarely fatal) bleeding from the stomach or intestines. This bleeding can occur without warning symptoms at any time during treatment.

Stop taking this medication and seek immediate medical attention if you notice any of the following rare but very serious side effects: chest pain, severe dizziness, trouble breathing, weakness on one side of the body, sudden vision changes, slurred speech, black stools, persistent stomach/abdominal pain, vomit that looks like coffee grounds. (See also Precautions section.)

Talk with your doctor or pharmacist about the risks and benefits of treatment with this medication.

USES: Mefenamic acid is used for the short-term treatment of mild to moderate pain from various conditions. It is also used to decrease pain and blood loss from menstrual periods.

Mefenamic acid is known as a nonsteroidal anti-inflammatory drug (NSAID).

HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using mefenamic acid and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Take this medication by mouth, usually 4 times a day with a full glass of water (8 ounces or 240 milliliters) or as directed by your doctor. Do not lie down for at least 10 minutes after taking this drug. If stomach upset occurs, take this medication with food or milk. Do not take mefenamic acid with antacids unless directed by your doctor. Certain antacids may change the amount of mefenamic acid absorbed by the body.

Dosage is based on your medical condition and response to therapy. To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time. Do not increase your dose, take it more frequently, or take it for a longer time than prescribed. This medication usually should not be taken for more than 7 days at a time.

If you are taking this drug on an "as needed" basis (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the symptoms have worsened, the medicine may not work as well.

If you are using this medication for painful periods, take your first dose as soon as your period starts or pain begins. Usually, you will only need to take it for the first 2 to 3 days of your period.

Inform your doctor if your pain persists or worsens or if you develop new symptoms.
