Diclofenac and misoprostol combination is used for patients with arthritis who may develop stomach ulcers from taking nonsteroidal anti-inflammatory drugs (NSAIDs) alone.

Misoprostol is used in this combination medicine to prevent stomach ulcers.

This medicine is available only with your doctor's prescription.

Before Using Arthrotec

If you will be taking this medicine for a long time, your doctor should check your progress at regular visits. Your doctor may want to do certain tests to find out if unwanted effects are occurring. The tests are very important because serious side effects, including ulcers, bleeding, blood, or liver problems, can occur without any warning.

Also, taking acetaminophen, aspirin or other salicylates, or ketorolac (e.g.,Toradol) regularly while you are taking a diclofenac and misoprostol combination may increase the chance of unwanted effects. The risk will depend on how much of each medicine you take every day, and on how long you take the medicine together. If your health care professional directs you to take these medicines together on a regular basis, follow his or her directions carefully. However, do not take acetaminophen or aspirin or other salicylates together with this medicine for more than a few days, and do not take any ketorolac (e.g., Toradol) while you are taking this medicine, unless your doctor has directed you to do so and is following your progress.
