Colchicine

(℞) Prescription Required - Colchicine is the Generic Equivalent of Colcrys

    What Is Colchicine?

    Colchicine, known commonly by its common brand name, Colcrys, is a prescription medication used to treat Gout attacks and/or gout flares. These symptoms usually manifest as hard crystals that form suddenly in the joints of the body due to increased levels of uric acid in the blood. Colchicine works by decreasing the swelling and build-up of uric acid crystals that cause pain in the affected joints - usually the big toe, knee, or ankle joints.

    Colchicine is also commonly used to prevent pain attacks in the abdomen, chest, or joints caused by the inherited disease, familial Mediterranean fever. In this regard, the drug is suspected to work by lowering the body’s production of amyloid A, a protein that builds up in people with familial Mediterranean fever. Although it’s used to assist in the prevention of pain caused by the symptoms of gout and familial Mediterranean fever, Colchicine is not a pain medication, and should not be taken to treat other causes of pain.

    Colchicine is taken orally with or without food, and its dose is prescribed by doctors and pharmacists depending on your medical condition. Taking more or less of the drug can alter the effectiveness of Colchicine, and may also increase the risk of potential side effects.

    Proper Use of this medication

    COLCRYS comes as a tablet to take by mouth in 0.5 milligrams (mg) or 0.6 mg doses. It can be taken with or without food.

    When used to prevent gout attacks or treat FMF, the drug is typically taken once or twice a day.

    When used to relieve pain from a gout attack, it's typically taken at the first sign of pain. Then, a smaller dose is usually taken about an hour later.

    If you're taking COLCRYS to treat FMF, your doctor might start you on a low dose of the drug and gradually increase it.

    You should follow the directions on your prescription label carefully. Don't take more or less of this medicine than is prescribed.

    Serious side effects or even death can result from using this drug improperly or without the advice of a doctor.

    Continue to take this medicine even if you feel well. Don't stop taking it without first talking to your doctor.
