COCHINE

# Colchicine 0.5 mg ## Short Description **Colchicine 0.5 mg** is an anti-inflammatory medicine primarily used to prevent and treat **gout flares** and to prevent gout attacks when starting urate-lowering therapy. It may also be prescribed for **familial Mediterranean fever (FMF)** and certain other inflammatory conditions when clinically appropriate. Colchicine does **not** lower uric acid levels. Instead, it reduces the inflammatory response caused by urate crystals. > **Important:** Colchicine has a **narrow therapeutic range**, meaning the difference between an effective dose and a toxic dose can be small. Take it exactly as prescribed and never exceed the recommended dose. --- ## Key Benefits * Helps relieve inflammation associated with **acute gout flares** * Helps prevent recurrent gout attacks * May be used to prevent gout flares when starting uric-acid-lowering medicines * Can be used for **familial Mediterranean fever (FMF)** when prescribed * Reduces inflammation caused by urate crystal deposition * Available in a convenient **0.5 mg strength** for individualized dosing --- ## Uses / Indications ### **Acute Gout Flares** Colchicine may be prescribed early during an acute gout attack to reduce inflammation, pain, swelling, and tenderness caused by urate crystals. ### **Prevention of Gout Flares** Low-dose colchicine may be used to prevent recurrent attacks of gout, particularly when starting or adjusting medicines such as: * Allopurinol * Febuxostat * Other urate-lowering therapies ### **Familial Mediterranean Fever** Colchicine is an established treatment for **familial Mediterranean fever (FMF)** and can help reduce inflammatory attacks and complications associated with the condition. ### Other Uses Doctors may prescribe colchicine for certain other inflammatory conditions based on clinical judgment and local treatment guidelines. --- ## How It Works Colchicine works by interfering with **microtubules**, structures that are important for the movement and activity of inflammatory cells. During a gout attack, urate crystals can trigger an intense inflammatory response. **Urate crystals → activate inflammatory cells → inflammation and pain** Colchicine interferes with inflammatory cell activity and reduces the inflammatory response. **Colchicine → disrupts microtubule function → reduces inflammatory cell activity → decreases gout-related inflammation** Colchicine **does not dissolve uric acid crystals and does not directly lower blood uric acid levels**. --- ## Dosage & Administration > **Important:** Colchicine dosing varies considerably depending on the condition, kidney/liver function, age, other medicines, and the specific product. Follow your prescription exactly. ### For Acute Gout Colchicine is most effective when started **early after symptoms begin**. The exact acute-gout regimen depends on the formulation and local prescribing information. Do not repeatedly take additional doses simply because pain continues. ### For Prevention of Gout Flares A healthcare professional may prescribe a low daily dose, such as **0.5 mg once or twice daily**, depending on the patient's circumstances. ### Familial Mediterranean Fever The dose is individualized according to: * Age * Disease severity * Kidney function * Liver function * Response to treatment ### How to Take Colchicine * Take exactly as prescribed. * Swallow the tablet with water. * It can generally be taken with or without food. * Taking it with food may help reduce stomach irritation in some people. * Do not increase the dose without medical advice. ### Kidney or Liver Impairment Patients with kidney or liver disease may require dose reduction or increased monitoring. Some combinations of kidney/liver impairment and interacting medicines may make colchicine **unsafe**. ### Missed Dose For preventive treatment, take the missed dose when remembered unless it is nearly time for the next dose. **Do not double the dose.** If colchicine is being used for an acute gout attack, follow the specific instructions provided by your healthcare professional. --- ## Side Effects ### Common Side Effects The most common adverse effects are gastrointestinal and may include: * Diarrhea * Nausea * Vomiting * Abdominal pain * Stomach discomfort **Diarrhea can be an early warning sign of colchicine toxicity**, particularly if it is severe or persistent. ### Serious Side Effects High levels of colchicine can cause serious toxicity, including: * Severe vomiting or diarrhea * Muscle weakness * Muscle pain * Numbness or tingling * Bone marrow suppression * Unusual bruising or bleeding * Severe infection * Kidney problems * Liver problems * Nerve damage * Severe muscle injury (**rhabdomyolysis**) * Multiple-organ failure Colchicine overdose can be **life-threatening**. Seek urgent medical attention if you suspect an overdose. --- ## Precautions & Warnings ### Narrow Therapeutic Range Colchicine has a narrow safety margin. Taking more than prescribed can result in severe or fatal toxicity. **Never take extra colchicine to obtain faster relief.** ### Kidney Disease People with impaired kidney function may accumulate colchicine and have a higher risk of toxicity. Tell your doctor if you have kidney disease or are receiving dialysis. ### Liver Disease Liver impairment can increase the risk of colchicine accumulation and toxicity. ### Older Adults Older adults may have a higher risk of muscle and nerve toxicity, particularly when kidney function is reduced or interacting medicines are being taken. ### Blood Disorders Long-term or excessive colchicine exposure can suppress bone marrow and reduce blood-cell production. Tell your healthcare professional if you develop: * Unexplained bruising * Bleeding * Persistent fever * Sore throat * Unusual infections * Severe weakness ### Muscle Toxicity Colchicine can rarely cause muscle injury or weakness, especially in patients with kidney disease or those taking certain interacting medicines. Report unexplained muscle pain, tenderness, or weakness. ### Pregnancy If you are pregnant or planning pregnancy, discuss colchicine treatment with your healthcare professional. ### Breastfeeding Colchicine can pass into breast milk. Discuss its use with your healthcare professional if you are breastfeeding. ### Dehydration Severe vomiting or diarrhea can worsen dehydration and increase the risk of complications. --- ## Drug Interactions Colchicine has several clinically important drug interactions. ### Clarithromycin and Erythromycin Macrolide antibiotics such as **clarithromycin** and erythromycin can increase colchicine concentrations and significantly increase the risk of toxicity. The combination may be contraindicated in some patients, particularly those with kidney or liver impairment. ### Strong CYP3A4 Inhibitors Medicines that strongly inhibit CYP3A4 can increase colchicine levels. Examples include certain: * Antifungal medicines * Macrolide antibiotics * HIV medicines ### P-glycoprotein (P-gp) Inhibitors Medicines such as **cyclosporine** and certain other P-gp inhibitors can substantially increase colchicine exposure. ### Statins Combining colchicine with statins may increase the risk of **muscle toxicity**, including myopathy or rhabdomyolysis. Examples include: * Atorvastatin * Simvastatin * Rosuvastatin This does not mean they can never be used together, but medical monitoring may be necessary. ### Other Medicines That Affect the Liver or Kidneys Certain medicines may increase the risk of colchicine toxicity, especially in patients with impaired kidney or liver function. Always tell your doctor about **all prescription medicines, over-the-counter medicines, vitamins, and herbal supplements** you take. --- ## Storage Information * Store colchicine according to the manufacturer's recommended temperature. * Keep tablets in the original packaging. * Protect from excessive heat and moisture. * Keep away from direct sunlight. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets from damaged or tampered packaging. --- ## Prescription Status **Colchicine 0.5 mg is generally a prescription medicine**, although legal classification can vary between countries.
