Summary
Penicillamine is used to treat rheumatoid arthritis, which is a condition causing joint pain and swelling, Wilson's disease, which is a genetic disorder leading to copper buildup in the body, and cystinuria, which is a condition that causes kidney stones.
Penicillamine works by binding to metals like copper in the body, forming a complex that is then excreted in the urine. This helps reduce excess copper levels and manage symptoms in conditions like Wilson's disease and rheumatoid arthritis.
The usual starting dose for adults is 250 mg daily, taken on an empty stomach. The dose may be gradually increased to a maximum of 1,500 mg per day. It's important to follow your doctor's specific dosing instructions for safe and effective treatment.
Common side effects of Penicillamine include nausea, which is a feeling of sickness with an inclination to vomit, loss of appetite, and skin rash. These effects occur in a small percentage of people taking the medication.
Penicillamine can cause serious side effects like bone marrow suppression, which affects blood cell production, and kidney damage. It's not recommended for people with kidney problems or during pregnancy unless necessary. Regular monitoring and following your doctor's advice are crucial for safe use.
