Uses
Diclofenac is used to reduce pain, swelling, and joint stiffness from arthritis. Diclofenac is known as a nonsteroidal anti-inflammatory drug (NSAID). Misoprostol protects the stomach from diclofenac's irritating effects. This combination medication is used to treat arthritis in people at high risk of getting stomach/intestinal ulcers and complications from the ulcers (such as bleeding).
If you are treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain. See also Warning section.

Precautions
See also Warning section.
Before taking this medication, tell your doctor or pharmacist if you are allergic to diclofenac or misoprostol; or to aspirin or other NSAIDs (such as ibuprofen, naproxen, celecoxib); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of:
- liver disease

- aspirin-sensitive asthma (a history of worsening breathing with runny/stuffy nose after taking aspirin or other NSAIDs)
- growths in the nose (nasal polyps)
Kidney problems can sometimes occur with the use of NSAID medications, including diclofenac. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.
This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Talk to your doctor if you are using marijuana (cannabis).
Diclofenac may cause stomach bleeding. Daily use of alcohol and tobacco, especially when combined with this medicine, may increase your risk for stomach bleeding. Limit alcohol and stop smoking. Ask your doctor or pharmacist about how much alcohol you may safely drink.
This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Older adults may be at greater risk for stomach/intestinal bleeding, kidney problems, heart attack, and stroke while using this drug.
This medication must not be used during pregnancy. It may harm the mother and unborn baby. Use reliable forms of birth control to prevent pregnancy while taking this medication and for at least one month or one completed menstrual cycle after stopping treatment. If you become pregnant or think you may be pregnant, tell your doctor right away.
This medication passes into breast milk but is unlikely to harm a nursing infant. Consult your doctor before breast-feeding.
Drug Interactions
See also How to Use section.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include:
- aliskiren
- ACE inhibitors (such as captopril, lisinopril)
- angiotensin II receptor blockers (such as valsartan, losartan)
- cidofovir
- corticosteroids (such as dexamethasone, prednisone)
- lithium
- methotrexate
- "water pills" (diuretics such as furosemide)
This medication may increase the risk of bleeding when taken with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.
Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as celecoxib, ibuprofen, or ketorolac). These drugs are similar to diclofenac and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually 81-162 milligrams a day), you should keep taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.
