What is colchicine used for?
Colchicine is a medicine used to treat and prevent attacks of gout and to treat some inflammatory conditions. It works by reducing inflammation related to crystal-driven immune signaling.
How does colchicine work?
Colchicine interferes with microtubule formation in cells, which affects how immune cells respond to inflammation. In gout, that means fewer inflammatory signals triggered by urate crystals during an attack.
How is colchicine taken (typical dosing patterns)?
Dosing depends on the condition being treated (acute gout flare vs. prevention) and patient factors such as kidney or liver function and drug interactions. If you’re looking for exact dosing, it’s important to follow your prescribing clinician’s instructions because colchicine dosing is adjusted for safety in people with organ impairment.
What side effects do people report most often?
The most common colchicine side effects are gastrointestinal, especially diarrhea, nausea, vomiting, and abdominal pain. More serious toxicity can occur, particularly with overdose or with interacting medicines that raise colchicine levels.
Can colchicine interact with other drugs?
Yes. Colchicine levels can rise when combined with certain inhibitors of drug transporters or metabolism pathways, increasing the risk of severe side effects. Patients are commonly warned to check all prescription and OTC medicines for interactions before starting.
What are the red flags that mean you should seek urgent care?
Seek urgent medical advice if you suspect overdose or develop severe diarrhea, weakness, numbness/tingling, muscle pain, or symptoms of significant toxicity—especially if kidney function is reduced or interacting drugs are involved.
