Tolchicine 600mcg Tablet 10s (strip)

Tolchicine 600mcg Tablet is a prescription medicine belonging to the alkaloid anti-inflammatory drug class, with colchicine as its active pharmaceutical ingredient — manufactured by T.O. Chemicals Sdn Bhd, a Malaysian pharmaceutical company, and registered with the National Pharmaceutical Regulatory Authority (NPRA) of Malaysia as a prescription-only medicine (POM). As with all medicines, Tolchicine 600mcg can cause side effects, and it is especially important that you are aware of these, as colchicine has a narrow therapeutic window — meaning the difference between a therapeutic dose and a toxic dose is relatively small; the most commonly reported side effects are diarrhoea, nausea, vomiting, and abdominal pain, particularly if the dose is too high or taken too frequently. It is critical that you take this medication strictly under the supervision of a registered doctor, declare all other medications you are currently taking (as some drug combinations with colchicine can be life-threatening), and never exceed the dose or frequency prescribed to you. Tolchicine 600mcg is a prescription-only medicine in Malaysia — please ensure you hold a valid prescription before purchasing, only buy from a licensed pharmacy or verified online pharmacy platform, and keep this medicine stored safely out of reach of children at all times, as even a small overdose in a child can be fatal.

How to Take Tolchicine 600mcg Tablet

Tolchicine 600mcg Tablet is taken orally — swallow the tablet whole with a full glass of water; it may be taken with or without food, though taking it with food may help reduce stomach discomfort, which is one of the most common reasons patients are unable to continue the prescribed course. The dosing schedule for Tolchicine varies considerably depending on whether it is being used for acute or preventive purposes — your doctor will prescribe a specific regimen for your condition, and it is essential that you follow this schedule precisely, including the prescribed rest period between doses, and never double-dose or self-administer beyond what has been prescribed. If you vomit shortly after taking a dose and are uncertain whether to retake it, contact your doctor or pharmacist rather than taking an additional tablet.

Dosage of Tolchicine 600mcg Tablet

The recommended adult dosage of Tolchicine 600mcg Tablet for acute treatment is typically 1 to 2 tablets (600mcg to 1200mcg) taken at the onset of symptoms, which may be repeated every 1 to 2 hours as directed by a doctor — however, the total dose must not exceed 6mg (10 tablets) over a single treatment course, and the course must not be repeated within 3 days. For preventive (prophylactic) dosing, the dosage and frequency are significantly lower and individualised by your doctor based on your renal function, age, and any concurrent medications; dose reduction is mandatory in elderly patients and those with renal or hepatic impairment, and Tolchicine 600mcg is not recommended for use in children.

Shelf Life of Tolchicine 600mcg Tablet

Tolchicine 600mcg Tablet has a manufacturer-stated shelf life clearly printed on the outer carton and the individual blister or strip packaging. Always check the expiry date before taking each tablet and never consume this medication after the stated expiration date, even if the tablets appear visually intact and unchanged, as chemical degradation over time may silently alter both the potency and safety profile of the product. Given the narrow therapeutic window of colchicine, using expired product — which may have unpredictable potency — carries particular safety risks compared to many other medicines. Properly stored unopened strip packs will retain their full pharmaceutical quality for the duration shown on the manufacturer’s packaging. Once dispensed by a pharmacy, respect any expiry or “use by” date applied by your pharmacist on the dispensing label, which may be earlier than the manufacturer’s stated date.

How to Store Tolchicine 600mcg Tablet

Store Tolchicine 600mcg Tablet below 25°C in a cool, dry location, protected from direct light and moisture. Keep the tablets in their original strip or blister packaging until you are ready to take them — the sealed aluminium-foil strip packaging protects the tablets from humidity and light degradation, both of which can accelerate chemical breakdown of the active ingredient.

In Malaysia’s characteristically warm and humid tropical climate, take particular care to avoid storing this medication in bathrooms, on windowsills, near kitchen appliances, or inside vehicles where temperatures can escalate rapidly during the day. Even short periods of exposure to excessive heat or humidity can compromise the stability of tablet formulations.

Colchicine is an extremely toxic substance, particularly in accidental ingestion by children — fatal overdoses have been reported in children who accessed improperly stored colchicine tablets. This medicine must be stored securely and completely out of sight and reach of children and pets at all times; do not store it in open medicine trays, on bedside tables, or in locations accessible to young family members.

Dispose of any unused, damaged, or expired tablets through a licensed pharmacy medication return or take-back programme, or in accordance with local pharmaceutical waste disposal guidelines. Do not flush tablets into drains, toilets, or discard them in household waste, as pharmaceutical residues — particularly from potent agents like colchicine — can cause environmental contamination.

Active Ingredient of Tolchicine 600mcg Tablet

The active pharmaceutical ingredient (API) in each Tolchicine 600mcg Tablet is Colchicine, present at a concentration of 600 micrograms (0.6mg) per tablet. Colchicine is a naturally occurring tropolone alkaloid derived from the autumn crocus plant (Colchicum autumnale) — one of the oldest medicinal compounds still in clinical use, with documented use in traditional medicine dating back to ancient Egypt and the early Byzantine era. Despite this long history, colchicine’s precise clinical pharmacology has been extensively studied and well-characterised in modern pharmaceutical science.

Pharmacodynamically, colchicine exerts its primary anti-inflammatory and cellular effects by binding with high affinity to tubulin — specifically at the colchicine-binding site at the interface between α- and β-tubulin heterodimers — thereby inhibiting tubulin polymerisation and preventing microtubule formation. Microtubules are essential cytoskeletal structures required for multiple critical cellular processes including mitotic spindle formation (cell division), intracellular vesicle transport, neutrophil locomotion, and phagocytosis. By disrupting microtubule dynamics, colchicine inhibits neutrophil migration into affected tissues, interferes with the activation of the NLRP3 inflammasome (a key driver of acute inflammatory cascades), and reduces the release of pro-inflammatory cytokines including interleukin-1β (IL-1β). The net result is a targeted reduction in the acute inflammatory response without the broad immunosuppressant effect seen with corticosteroids.

Pharmacokinetically, colchicine is rapidly absorbed from the gastrointestinal tract following oral administration, with peak plasma concentrations (Tmax) typically occurring within 0.5 to 2 hours. The absolute oral bioavailability is approximately 45%, reflecting partial first-pass hepatic metabolism. Colchicine is a dual substrate of the P-glycoprotein (P-gp) efflux transporter and the CYP3A4 cytochrome P450 enzyme — a pharmacokinetic property of critical clinical importance, as inhibition of either or both of these pathways by interacting drugs can significantly and dangerously increase systemic colchicine concentrations. Plasma protein binding is modest at approximately 39%. The mean elimination half-life in healthy adults is 26 to 31 hours, though this may be substantially prolonged in patients with renal or hepatic impairment. Colchicine undergoes hepatic demethylation via CYP3A4 to form two primary metabolites (2-O-demethylcolchicine and 3-O-demethylcolchicine), both of which are pharmacologically less active than the parent compound. Elimination occurs principally via biliary and faecal routes, with 40 to 65% of an oral dose recovered unchanged in urine — meaning that renal impairment significantly impacts drug clearance and requires mandatory dose adjustment.

Each Tolchicine 600mcg Tablet also contains standard pharmaceutical excipients used as tablet-forming agents. Patients with any known drug or excipient sensitivities should review the complete inactive ingredient list with their pharmacist or doctor before use.

Side Effects of Tolchicine 600mcg Tablet

Colchicine has a narrow therapeutic window, meaning side effects — many of which reflect early toxicity — can occur at or near therapeutic doses, particularly in patients with renal or hepatic impairment, in elderly patients, or in those concurrently taking CYP3A4 or P-gp inhibitors. The following adverse effects have been identified with colchicine-containing products at therapeutic doses:

Very Common / Common Side Effects (Gastrointestinal — most frequently reported):

• Diarrhoea — the most commonly reported adverse effect; occurs in up to 23% of patients and may be severe; diarrhoea is often an early warning sign of colchicine accumulation
• Nausea and vomiting
• Abdominal pain, cramping, or bloating
• Flatulence (excessive gas)
• Gastrointestinal haemorrhage (GI bleeding) — less common, but reported

Uncommon to Rare Side Effects:

• Myelosuppression — suppression of bone marrow function, potentially presenting as leukopenia (low white blood cell count), granulocytopenia, thrombocytopenia (low platelet count), pancytopenia (reduction in all blood cell lines), or aplastic anaemia; this is a serious haematological toxicity requiring immediate medical attention
• Myopathy — muscle pain (myalgia), proximal muscle weakness, and elevated serum creatine kinase (CK); more common in patients with renal impairment or those taking concurrent statin or cyclosporine therapy
• Rhabdomyolysis — severe breakdown of skeletal muscle leading to release of myoglobin into the bloodstream, which can cause acute kidney injury; characterised by severe muscle pain, weakness, and dark or tea-coloured urine; requires emergency medical treatment
• Peripheral neuropathy — numbness, tingling, or burning sensation in the hands or feet; associated with long-term use or toxicity
• Neuromuscular toxicity — presenting as combined myopathy and peripheral neuropathy; more common in elderly patients and those with renal dysfunction
• Alopecia (hair loss) — typically reversible upon dose reduction or discontinuation
• Skin rash or dermatitis
• Elevated hepatic enzyme levels (ALT, AST) — indicating liver stress
• Renal impairment or acute kidney injury — particularly in the context of myoglobinuria from rhabdomyolysis
• Oligospermia or azoospermia (reduced sperm count or absence of sperm) — associated with long-term use in males; typically reversible upon discontinuation
• Amenorrhoea (absence of menstruation) — rare; reported in female patients on long-term therapy

Signs and Symptoms of Colchicine Toxicity — Seek Emergency Medical Attention Immediately:

• PHASE 1 — Early toxicity (within 24 hours): Severe diarrhoea (often profuse and watery), nausea, vomiting, abdominal pain; this early phase may initially resemble a gastrointestinal infection but is a warning sign of systemic toxicity
• PHASE 2 — Multi-organ failure (1–7 days): Cardiovascular collapse (hypotension, arrhythmias, cardiac failure), acute kidney injury (oliguria, elevated serum creatinine), hepatic dysfunction, respiratory distress, bone marrow suppression (pancytopenia), hyperpyrexia (very high fever), ascending neuromuscular paralysis, and confusion or altered mental status
• PHASE 3 — Recovery or death: Patients who survive multi-organ failure may enter a recovery phase with rebound leukocytosis (elevated white cell count); however, fatalities have been reported from colchicine overdose in adults and children — there is no specific antidote; treatment is supportive
• CRITICAL: Symptoms of colchicine toxicity may be delayed by up to 12 hours after ingestion. If overdose is suspected — even if the patient feels well — seek emergency medical care immediately. Do not wait for symptoms to appear.

Contraindications of Tolchicine 600mcg Tablet

Tolchicine 600mcg Tablet must NOT be used in the following patients and clinical circumstances:

Absolute Contraindications — Do Not Use:

• Concurrent use of both a P-glycoprotein (P-gp) inhibitor AND a strong CYP3A4 inhibitor in patients with renal or hepatic impairment — this combination has resulted in life-threatening and fatal colchicine toxicity even at therapeutic doses; if a patient with renal or hepatic impairment requires a dual P-gp/CYP3A4 inhibitor, Tolchicine must not be used and an alternative should be considered
• Patients with both renal AND hepatic impairment concurrently — the severely impaired clearance from both routes makes colchicine accumulation to toxic levels highly likely; Tolchicine is absolutely contraindicated in this group regardless of other medications
• Known hypersensitivity or allergy to colchicine or to any inactive excipient in the Tolchicine 600mcg Tablet formulation — hypersensitivity reactions are rare but have been reported
• Severe renal impairment (estimated creatinine clearance below 10 mL/min or patients on dialysis) requiring concurrent use with P-gp or strong CYP3A4 inhibitors
• Children under 12 years of age — Tolchicine 600mcg is not recommended for paediatric use; colchicine has a particularly narrow safety margin in children and fatalities from accidental paediatric ingestion have been documented globally
• Known biliary obstruction — colchicine is partially eliminated via the biliary route; obstruction significantly reduces drug clearance and increases toxicity risk

Use with Special Caution — Medical Review and Dose Adjustment Required:

• Renal (kidney) impairment (any degree) — since 40–65% of colchicine is excreted unchanged in the urine, renal impairment significantly reduces clearance and increases the risk of toxicity; dose reduction and/or increased dosing intervals are required in proportion to severity of impairment; regular monitoring of renal function is recommended
• Hepatic (liver) impairment — colchicine undergoes significant hepatic metabolism via CYP3A4; liver disease impairs drug clearance and increases exposure to toxic concentrations; dose adjustment is necessary and close monitoring is mandatory
• Elderly patients (over 65 years) — older patients are at substantially higher risk of colchicine-induced neuromuscular toxicity and rhabdomyolysis, even when taking therapeutic doses and even in the presence of normal renal and hepatic function; dose reduction is generally recommended for elderly patients
• Concurrent use of any CYP3A4 inhibitor or P-gp inhibitor (even moderate inhibitors) in patients with otherwise normal organ function — dose adjustment of colchicine is required; the combination should be avoided wherever possible
• Haematological disorders or pre-existing bone marrow depression — colchicine can further suppress bone marrow function; use only with close haematological monitoring
• Pregnancy — colchicine crosses the human placenta; animal studies have demonstrated embryotoxicity, teratogenicity, and altered postnatal development at exposures within or above the clinical therapeutic range; available human data (mostly from familial Mediterranean fever / FMF patients) have not identified a specific pattern of birth defects, but the risk cannot be fully excluded; use only when the clinical benefit clearly outweighs the potential foetal risk, under specialist medical supervision
• Breastfeeding — colchicine is excreted in human breast milk; available data in breastfeeding women have not identified serious adverse effects in nursing infants, but due to colchicine’s toxicity potential, breastfeeding should be undertaken only after careful risk-benefit discussion with a doctor; it is generally recommended to discontinue breastfeeding while taking colchicine
• Women of childbearing age — effective contraception is strongly advised during treatment; colchicine may cause foetal harm if conception occurs during therapy
• Males with known or planned fertility goals — long-term colchicine use has been associated with reversible oligospermia or azoospermia; discuss fertility implications with your doctor before commencing long-term therapy
• Concurrent use of HMG-CoA reductase inhibitors (statins) — e.g., atorvastatin, simvastatin, pravastatin, fluvastatin, lovastatin; statins are independently associated with myotoxicity, and concurrent use with colchicine substantially increases the risk of myopathy and rhabdomyolysis
• Known or suspected bowel obstruction — avoid in patients with gastrointestinal obstruction

Drug & Food Interaction of Tolchicine 600mcg Tablet

⚠ CRITICAL SAFETY NOTICE: Certain drug combinations with colchicine have caused fatal toxicity at therapeutic doses. The interaction risk is highest in patients with renal or hepatic impairment. Always disclose ALL medications to your doctor and pharmacist before starting Tolchicine.

Life-Threatening Drug Interactions — Dual P-gp and CYP3A4 Inhibitors (CONTRAINDICATED in Renal/Hepatic Impairment):

Colchicine is a dual substrate of both the P-glycoprotein (P-gp) efflux transporter and the CYP3A4 cytochrome P450 enzyme. Drugs that inhibit both pathways simultaneously cause the greatest and most dangerous increases in colchicine plasma concentrations. Such combinations have caused fatal outcomes even at therapeutic colchicine doses.
