Penicillamine
About Penicillamine
Penicillamine is an oral prescription medication used to manage excess copper levels in the body, prevent certain types of kidney stones, and treat severe active rheumatoid arthritis. It acts as a binding agent that helps clear heavy metals from your bloodstream and tissues. Doctors typically prescribe it when other standard treatments have not provided sufficient relief.
To ensure this medication works effectively, you must take it consistently every single day exactly as prescribed by your healthcare provider. For proper absorption, take this medicine on an empty stomach, at least one hour before or two hours after a meal. Making specific dietary adjustments, such as drinking large amounts of water or avoiding copper-rich foods, can significantly improve your treatment outcomes.
While taking Penicillamine, you may experience some common side effects such as temporary changes in your sense of taste, mild nausea, or soft stools. However, you must contact your doctor immediately if you experience more serious symptoms, such as unexplained bruising, severe skin rashes, or swelling in your face and ankles.
Before starting this treatment, tell your doctor if you have a history of kidney disease, liver damage, or blood disorders. Do not take this if you have severe kidney impairment, are breastfeeding, or have previously developed bone marrow disorders while using this medication.
This medicine can interact with iron supplements, zinc, and antacids, which block your body from absorbing it. You should also avoid drinking alcohol as it can increase stomach irritation and place extra stress on your organs. If you are pregnant, planning a pregnancy, or are an elderly patient, discuss the unique safety risks with your doctor before taking this medicine.

Patients Concern
Disease/Condition Glossary
Rheumatoid arthritis: It is an autoimmune disease (the body's immune system attacks its tissue), leading to joint pain and damage. Symptoms of rheumatoid arthritis include pain, joint inflammation, difficulty moving, and swelling.
Wilson’s disease: It is a rare genetic disorder that causes excess copper in the body. Copper plays an important role in the development of healthy nerves, bones, collagen, and the skin pigment melanin. Normally, copper is absorbed from the food; the liver filters out excess copper and releases it through urine. In People with Wilson’s disease, the liver cannot properly remove excess copper, and it then builds up in organs such as the brain, liver, and eyes.
Cystinuria: It is a condition in which the amino acid called cystine is present in the urine, leading to the formation of cystine stones in the kidneys, ureters, and bladder. Cystinuria symptoms usually include sharp pain in the lower back or side of the abdomen (renal colic), blood in the urine (hematuria), urinary tract obstruction, and urinary tract infections.
