This medication can cause serious (sometimes fatal) side effects, including diarrhea that doesn't go away, blood cell problems (such as anemia, low white blood cells/platelets), kidney problems, rash, itching, or mouth sores/irritation (stomatitis). Low white blood cells can increase your risk of infection. See Side Effects section for more details. Tell your doctor right away if you develop any of these side effects.
Your doctor will be closely monitoring certain lab tests (such as white blood cells, platelets) before you start taking this medication and while you are taking it. It is important that you keep all medical/lab appointments.
This medication is used as part of a complete treatment program including non-drug therapies (such as rest, physical therapy) to treat active rheumatoid arthritis. It is used to treat patients with severe rheumatoid arthritis who have not responded to or cannot take other medications. Auranofin is a gold compound.
Auranofin is not a true pain reliever (such as like aspirin) but it is thought to decrease pain that occurs with arthritis by decreasing inflammation. It is known as a disease-modifying antirheumatic drug (DMARD). It decreases morning stiffness and pain/swelling in joints and can increase grip strength.
Read the Patient Information Leaflet if available from your pharmacist before you start taking auranofin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually once or twice a day. Dosage is based on your medical condition and response to therapy. To decrease side effects such as upset stomach, your doctor may start you at a low dose (once a day) and slowly increase to twice a day. Do not increase your dose or take this medication more often without your doctor's approval. Your condition will not improve any faster, and the risk of serious side effects may be increased. The usual maximum adult dose is 9 milligrams each day.
Almost half of all patients have diarrhea or more frequent/loose stools while taking this medication. If this lasts or becomes a problem, your doctor may lower the dose or have you temporarily stop the medication. Do not stop or change the dose of your medicine without talking with your doctor.
