Gold sodium thiomalate is not a true pain reliever, 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.
This medicine is injected into a muscle by a healthcare professional, usually in the buttock. You will need to lie down during your injection and for 10 minutes afterward to lower the risk of side effects such as dizziness. You will be monitored for 15 minutes after your injection. When you begin therapy, injections are usually given once a week or as directed by your doctor.
Dosage is based on your medical condition and response to therapy. Injections are usually given once a week until improvement occurs or you have received a total of 1 gram. Once improvement occurs, your doctor may decrease your injections to once every 2-3 weeks or less. If your arthritis worsens, your doctor may order weekly injections again.
Use this medication regularly in order to get the most benefit from it. Keep all medical appointments.
