This medication is a combination of 2 drugs, diclofenac and misoprostol. Do not take this medication if you are pregnant or think that you may be pregnant. Misoprostol may cause loss of pregnancy, premature birth, or birth defects. In rare cases, serious complications (e.g., uterine rupture) have occurred when misoprostol was used to start labor or used in combination with another drug to end pregnancy after the eighth week. These complications have resulted in harm to the unborn baby and mother.
Avoid pregnancy while taking this medication and for at least one month or one complete menstrual cycle after you have stopped treatment. If you become pregnant while taking this medication, contact your doctor immediately.
If you are of a woman of childbearing age, do not use this medication unless you require a nonsteroidal anti-inflammatory drug (NSAID) such as diclofenac and you are at high risk of having an ulcer or ulcer complications from NSAID treatment.
Female patients must meet the following four requirements in order to use this drug: 1) test negative for pregnancy within 2 weeks before starting treatment; 2) use effective birth control to prevent pregnancy; 3) receive oral and written warnings on the dangers of using misoprostol while of childbearing age and the risks of possible birth control failure; 4) start taking this medication only on the second or third day of the next normal menstrual period.
This medication must not be shared with others.
Diclofenac may infrequently cause serious (rarely fatal) bleeding from the stomach or intestines. This side effect can occur without warning at any time during treatment with diclofenac. The elderly are at increased risk for serious stomach/intestinal bleeding.
Drugs related to diclofenac have rarely caused blood clots to form, resulting in serious (possibly fatal) heart attacks and strokes. This medication might also rarely cause similar problems. The risk of these serious side effects may be greater if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes), or with longer use of this medication. This drug should not be taken right before or after heart bypass surgery (CABG).
Stop taking this medication and seek immediate medical attention if you notice any of the following rare but very serious side effects: black stools, persistent stomach/abdominal pain, vomit that looks like coffee grounds, chest pain, shortness of breath, weakness on one side of the body, sudden vision changes, slurred speech.Who should not take Arthrotec 50?
Diclofenac is used to relieve pain, swelling (inflammation), and joint stiffness caused by arthritis. Reducing these symptoms helps you do more of your normal daily activities. 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 developing stomach ulcers and serious complications 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.

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 any unusual change in the amount of urine.
Before having surgery, tell your doctor or dentist that you are using this medication.

This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use a sunscreen and wear protective clothing when outdoors.
Older adults may be more sensitive to the side effects of this drug, especially stomach/intestinal bleeding, kidney problems, and worsening heart problems.

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 (e.g., prednisone), cyclosporine, desmopressin, digoxin, lithium, methotrexate, pemetrexed, probenecid, "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 at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.
