Common use
Colchicine is a well-known anti-inflammatory medication primarily indicated for the treatment of acute gout flare-ups and for preventing recurrent gout attacks in individuals with chronic gout conditions. It is also commonly prescribed for managing familial Mediterranean fever (FMF), a hereditary inflammatory disorder.
The medication works by suppressing the body's immune response to uric acid crystal accumulation, which reduces inflammation, swelling, and pain during gout episodes.
Dosage and direction
Colchicine must be used exactly as prescribed by a healthcare professional. For acute gout attacks, the initial recommended dosage is typically 1.2 mg, followed by an additional 0.6 mg dose after one hour. For long-term gout prevention, 0.6 mg once or twice daily is commonly used.
It can be taken with or without food, accompanied by a full glass of water. Avoid consuming grapefruit or grapefruit juice, as it can affect how the body metabolizes colchicine and may raise the risk of side effects.
This drug has a narrow therapeutic window, so taking more than the recommended amount can be dangerous.
Precautions
Before initiating colchicine, notify your doctor if you have or have had:
Liver impairment
Kidney disease
Digestive disorders or stomach ulcers
Blood cell abnormalities
Special caution is needed for elderly patients, pregnant women, and breastfeeding mothers, as the drug's effects may be more pronounced in these groups. Colchicine should only be used during pregnancy when clearly needed and prescribed by a physician.
Contraindications
Colchicine is contraindicated in patients who:
Are hypersensitive to colchicine or its components
Have severe renal or hepatic impairment, especially when used with strong inhibitors
Are currently taking CYP3A4 inhibitors (e.g., clarithromycin) or P-glycoprotein inhibitors (e.g., cyclosporine), as these increase colchicine toxicity
Possible side effects
Like all medications, colchicine may cause side effects. Common ones include:
Nausea
Vomiting
Abdominal cramps
Diarrhea
Serious (though rare) side effects may include:
Muscle weakness or pain (signs of myopathy)
Numbness or tingling sensations
Unexplained bruising or bleeding
Fever or signs of infection
If any severe reactions occur, discontinue use and seek immediate medical assistance.
Drug interactions
Colchicine can interact with a wide range of medications. Dangerous interactions may occur with:
Macrolide antibiotics (e.g., clarithromycin, erythromycin)
Antifungals (e.g., ketoconazole, itraconazole)
Immunosuppressants (e.g., cyclosporine)
Statins (e.g., simvastatin, which increases muscle damage risk)
Always inform your doctor or pharmacist of all prescription, non-prescription, and herbal products you are currently taking.
Missed dose
If a dose is missed, take it as soon as you remember. If the next scheduled dose is near, skip the missed one and return to your regular schedule. Do not double the dose.
Overdose
Overdosing on colchicine can be life-threatening. Early symptoms may include nausea, vomiting, and diarrhea, followed by serious complications such as respiratory depression, muscle breakdown, kidney failure, or bone marrow suppression.
Emergency medical treatment is essential in suspected overdose cases.
Storage
Keep colchicine stored at room temperature (68°-77°;F or 20°-25°;C), protected from direct light and moisture. Make sure the container is sealed tightly and stored away from children and pets.
U.S. Sale and Prescription Policy
Colchicine is a prescription-only medication in the United States and is approved by the FDA for the treatment of gout and FMF. Its usage requires careful medical supervision due to its potency and interaction profile.
While federal law mandates a prescription, it's important to note that Home Care Pharmacy provides a legal and compliant option for purchasing colchicine without a prescription, where allowed by state regulations or under pharmacist-managed care protocols.
Patients may consult with a licensed pharmacist to assess eligibility and safety. This approach allows for broader access to essential medications while maintaining compliance with U.S. health standards.
