The recommended dose for treating rheumatoid arthritis is Arthrotec 50 given 3-4 times daily. If this regimen is not tolerated, Arthrotec 50 or 75 twice a day may be used. Administering Arthrotec twice daily is less effective for preventing ulcers. Taking Arthrotec with food may reduce stomach upset. It is recommended that Arthrotec not be taken with alcohol because of the increased risk for ulcers.

DRUG INTERACTIONS: (Please also see the drug information for diclofenac.) Diclofenac is generally used with caution in patients taking blood thinning medications (anticoagulants), such as warfarin (Coumadin), because of the increased risk of bleeding.

Patients taking lithium (Eskalith, Lithobid) can develop toxic blood levels of lithium because diclofenac may inhibit the elimination of lithium from the body by the kidney.

Side effects from methotrexate (Rheumatrex, Trexall) and cyclosporine also may be increased by diclofenac.

Diclofenac may reduce the effectiveness of blood pressure-lowering drugs. Since prostaglandins are important in the control of blood pressure.
