Read the Medication Guide provided by your pharmacist before you start taking meclofenamate and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually 3 to 4 times a day or as needed. Take this medication with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this medication. If stomach upset occurs while taking this medication, take it with food, milk, or an antacid.

The dosage and length of treatment are based on your medical condition and response to treatment. 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 or use this drug more often or for longer than prescribed. For ongoing conditions such as arthritis, keep taking this medication as directed. Discuss the risks and benefits with your doctor or pharmacist.

For certain conditions (such as arthritis), it may take up to 3 weeks of taking this drug regularly until you get the full benefit.

If you are taking this drug "as needed" (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 pain has worsened, the medicine may not work as well.

Tell your doctor if your condition gets worse.
