Depen (Penicillamine) Dosage and Side Effects
Depen is used to remove excess copper associated with Wilson's disease. It is also used to reduce cystine in the urine and to treat severe rheumatoid arthritis.
Proper Use of this medication
Take DEPEN exactly as directed by your doctor. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.
Take each dose with a full glass of water.
DEPEN must be taken on an empty stomach, at least 1 hour before or 2 hours after a full meal, and at least 1 hour before or after any other drug, food, or milk. Taking DEPEN with anything else in the stomach greatly decreases its effectiveness.
Do not stop taking DEPEN without first talking to your doctor. Stopping therapy may cause your body to react abnormally when therapy is restarted. If you do stop taking the medication, do not restart without first talking to your doctor. You may need special monitoring.
Your doctor may want you to take a vitamin and mineral supplement during treatment with DEPEN. DEPEN may reduce vitamin B6 and iron in the body. Follow your doctor's instructions.
Store DEPEN at room temperature away from moisture and heat.
Seek emergency medical attention.
Symptoms of a DEPEN overdose are not known.
Take the missed dose on an empty stomach as soon as you remember. However, if it is almost time for your next dose, skip the dose you missed and take only your next regularly scheduled dose. Do not take a double dose of this medication unless otherwise directed by your doctor. If you have missed several doses in a row, do not take any more doses without first talking to your doctor.

Warnings and Precautions
Notify your doctor immediately if you develop fever; chills; a sore throat; unusual bruising or bleeding; blood in your urine, unexplained shortness of breath, coughing, or wheezing; muscle weakness; or double vision. These symptoms could be early signs of dangerous side effects.

Before taking DEPEN, tell your doctor if you have kidney disease or any other serious illness. You may not be able to take DEPEN, or you may require a lower dose or special monitoring during therapy.
