What is Arthrotec?
Arthrotec contains a combination of diclofenac and misoprostol. Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing substances in the body that cause pain and inflammation.
Misoprostol reduces stomach acid and replaces protective substances in the stomach that are reduced by NSAIDs.
Arthrotec may also be used for purposes not listed in this medication guide.
Do not use Arthrotec if you are pregnant. Misoprostol can cause birth defects, miscarriage, premature labor, or rupture of the uterus. You must have a negative pregnancy test within 2 weeks before you start taking Arthrotec. You may need to start taking this medicine only on the 2nd or 3rd day of a normal menstrual period. Use effective birth control while you are using Arthrotec.
Diclofenac can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use Arthrotec just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
You should not use Arthrotec if you have active bleeding in your stomach or intestines.
Diclofenac may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using diclofenac, especially in older adults. You should not use Arthrotec if you have active bleeding in your stomach or intestines.

How should I take Arthrotec?
Take Arthrotec exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition.
Take Arthrotec with food or milk to lessen stomach upset.
Swallow the tablet whole. Do not crush, break, or chew the pill.
Do not share Arthrotec with anyone else, even if they have the same symptoms you have.
If you use Arthrotec long-term, you may need frequent medical tests at your doctor's office.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking Arthrotec?
Avoid exposure to sunlight or tanning beds. Arthrotec can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
Avoid using antacids without your doctor's advice. Use only the type of antacid your doctor recommends. Some antacids can make it harder for your body to absorb Arthrotec.
Avoid drinking alcohol. It may increase your risk of stomach bleeding caused by diclofenac.
Avoid taking aspirin or other NSAIDs.
Ask a doctor or pharmacist before using any cold, allergy, or pain medicine. Many medicines available over the counter contain aspirin or other medicines similar to diclofenac. Taking certain products together can cause you to get too much of this type of medication. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.
