Colchicineside effects

Gastrointestinal disorders are the most common adverse reactions with colchicine. They are often the first signs of toxicity and may indicate that the colchicine dosage needs to be reduced or therapy stopped. These include diarrhea, nausea, vomiting, and abdominal pain. Colchicine has been reported to cause neuromuscular toxicity, which may present as muscle pain or weakness. Toxic manifestations associated with colchicine include myelosuppression, disseminated intravascular coagulation, and injury to cells in the renal, hepatic, circulatory, and central nervous system. These most often occur with excessive accumulation or overdosage. The following reactions have been reported with colchicine. These have been generally reversible by interrupting treatment or lowering the dose of colchicine: Digestive: abdominal cramping, abdominal pain, diarrhea, lactose intolerance, nausea, vomiting Neurological: sensory motor neuropathy Dermatological: alopecia, maculopapular rash, purpura, rash Hematological: leukopenia, granulocytopenia, thrombocytopenia, pancytopenia, aplastic anemia Hepatobiliary: elevated AST, elevated ALT Musculoskeletal: myopathy, elevated CPK, myotonia, muscle weakness, muscle pain, rhabdomyolysis Reproductive: azoospermia, oligospermia The most commonly reported adverse reactions with colchicine are gastrointestinal symptoms, including diarrhea, nausea, vomiting, and abdominal pain.
