Penicitin Capsule belongs to the group of medicines called ‘chelating agents’ used to treat severe rheumatoid arthritis, Wilsons disease, and cystinuria. Rheumatoid arthritis is a joint disorder in which our immune system attacks our body cells. Wilson disease is a genetic problem characterized by excess copper deposited in body parts like the eye, brain, and liver leading to metal toxicity. Cystinuria is the excess build-up of an amino acid called cystine in the urinary bladder and kidney, leading to harmful effects. 

Penicitin Capsule contains Penicillamine which works by blocking the action of certain chemical messengers responsible for inflammation and slows the progress of the condition with certain joint diseases. It works in Wilson's disease by binding to the extra copper in the body and causing it to leave the body through the urine. Decreasing copper levels improves liver function, and mental, mood, and nerve problems (like confusion, and difficulty speaking or walking) caused due to Wilson's disease. Besides this, Penicitin Capsule is also used to treat cystinuria (kidney and bladder stone) and lead poisoning.

Take Penicitin Capsule exactly as prescribed by your doctor. You are advised to take Penicitin Capsule for as long as your doctor has prescribed it for you depending on your medical condition. In some cases, you may experience certain common side effects such as protein in the urine, low blood platelets, stomach upset or throwing up, diarrhoea, change in taste, loss of appetite,  mouth irritation, and mouth sores. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.

To avoid recurring symptoms, do not stop it midway. Do not take Penicitin Capsule if you are pregnant or planning for pregnancy as Penicitin Capsule causes serious congenital disabilities.

Inform your doctor about your health condition and medicines to rule out any unpleasant side effects.

Penicitin Capsule contains Penicillamine primarily used to treat Wilson's disease (copper builds up in the body and may result in serious symptoms) and cystinuria (kidney stones). It is also used in combination with other treatments to treat severe rheumatoid arthritis. The treatment of rheumatoid arthritis Penicitin Capsule reduces pain, inflammation, and slow joint damage and disease progression over time; hence Penicitin Capsule is known as a disease-modifying anti-rheumatic drug (DMARD). In Wilson's disease, Penicitin Capsule works by binding to the extra copper in the body and causing it to leave the body through the urine. Decreasing copper levels improves liver function and the mental, mood, and nerve problems (such as confusion, and difficulty speaking/walking) caused by Wilson's disease. In cystinuria, it helps decrease the amount of a certain substance (cystine) by binding to that substance which can cause kidney stones and prevent it from building up and forming stones. Besides this, Penicitin Capsule is also used to treat lead poisoning.

Do not take Penicitin Capsule if you are allergic (hypersensitive) to penicillamine or any of the other ingredients in it. Inform your doctor if you have severe kidney problems, lupus erythematosus (an auto-immune disorder), agranulocytosis (a low white cell blood count), aplastic anaemia (symptoms including feeling tired, breathless, having pale skin and more susceptible to infection) or thrombocytopenia (a blood disorder which causes bleeding into your skin, bruising and bleeding more than normal). Do not take Penicitin Capsule if you are pregnant or planning to get pregnant and breastfeeding. This medicine may cause harm to the unborn baby if you take it while you are pregnant. Caution should be required while taking Penicitin Capsule by elderly patients as they may be at greater risk of suffering side effects if you are taking Penicitin Capsule over a long time, especially if you are on a restricted diet, as this medicine increases the requirement for pyridoxine (Vitamin B6) so your doctor may also prescribe this vitamin for you. If you are taking iron tablets, antacids, or digoxin (used to treat heart failure), please maintain two hours gap between these tablets and Penicitin Capsule . Low blood cell counts have happened while taking Penicitin Capsule . If blood cell counts get very low, this can lead to bleeding problems, infections, or anaemia, and sometimes, these have been deadly.
