How this medicine works
In Clinical Pharmacology, this dated historical label describes colchicine binding to tubulin and affecting microtubule polymerisation and cell activity in inflammatory processes. It helps explain a label term, not diagnose joint pain, inflammation or another symptom, and it does not determine anyone's tablet count, initiation, stopping, co-use or switching.

A medicine may use different brand names across markets. Keep the market, brand, generic name, dosage form and route together; one matching field does not prove that two packs are the same or interchangeable.

What this page can show
This is a source-traceable public record. It helps you read the product identity and its listed source documents; each market still needs its own current record check.
What to bring to the next conversation
Bring the actual pack, the label or prescription, and a complete medicine list when you speak with a pharmacist or clinician.

PRODUCT PRESENTATION IDENTITY
Strength, pack and device identity
Package strength is not an individual dose. These fields help identify the exact labelled product; they do not calculate how much, how often, a missed-use action, splitting, switching or conversion.
How to read a score line: ‘scored’ or ‘unscored’ first identifies this labelled presentation. A score line by itself does not permit self-splitting, reducing or changing the product. Only an explicit statement in the current label for this exact presentation, checked with a pharmacist against the prescription, can support any further handling.

First match the market, dosage form and labelled amount on the pack in hand. The number of tablets, sachets or devices in a pack is not a personal dose or schedule.

PUBLIC LABEL IMAGE
Appearance and package-text clues
This dated or historical public-label image is for checking the brand, generic-name, strength and dosage-form clues only. It does not authenticate a product or establish originator status, a current label, current packaging, target-market approval or sale eligibility.
Open the public label source ↗LABEL READING · NOT A PRESCRIPTION
COLCRYS historical-label reading: 0.6 mg, NDC and a 30-tablet bottle first identify a historical product
Reading level: drug-specific label reading. This record has been expanded around its dosage form or a higher-risk reading question; the current target-market label and professional review still apply.
This module reads only COLCRYS, colchicine, 0.6 mg per tablet, NDC 64764-119-07, a 30-tablet bottle and appearance text in one dated U.S. historical public label. The record lists a U.S. marketing end date of 30 Apr 2026; this page provides no individual tablet count, initiation, stopping, make-up use, splitting, co-use, switching or purchase plan.
- Check COLCRYS, colchicine, 0.6 mg, the actual NDC, the 30-tablet bottle, oral-tablet form and target market together. 0.6 mg is the labelled amount for this exact historical tablet, not an answer to how many tablets anyone should use or whether another product can be exchanged.
- Purple colour, AR 374, the oval/capsule shape and scoring are identity clues for this exact historical labelled tablet. They cannot authenticate a photo and are not permission to self-split, make up, adjust, stop or switch. If the actual pack, prescription or market differs, take the pack to a pharmacist or prescribing team.
- The historical label flags interaction risk with strong P-gp or CYP3A4 inhibitors and calls for review of every prescription medicine, OTC product, supplement and recent addition such as an antibacterial. With kidney or liver problems, older age, multiple conditions or multiple medicines, do not self-start, increase, repeat, stop or switch from a webpage; a pharmacist or clinician should review the exact product and complete medicine list.
- With severe diarrhoea or vomiting, marked weakness, muscle pain or weakness, numbness or tingling, unusual bleeding/bruising, fever, infection-like symptoms, breathing difficulty or another acute serious concern, promptly use local urgent medical care; do not use a webpage to determine the cause or adjust medicine.

PRIVATE FAMILY LIST
Bring this record into a local medicine list
Only the brand, generic name, dosage form and route are added, and they stay in this browser. Copy strength, label directions, start/stop history and any concern from the actual pack; this tool does not calculate a dose or decide combination, switching or stopping.

Six checks for this medicine pack
Use this card to organise questions about COLCRYS (colchicine). Keep the exact pack, its current label and the full medicine list together.
Identify the exact product
COLCRYS is the brand in this record and colchicine is the active-ingredient name. Check both with the dosage form (Dosage form and presentation as documented in the linked primary label) and the market on the actual pack.
Read the labelled strength in context
mg, mcg, mg/mL or a percentage describes the labelled amount in one tablet, capsule, measured volume, spray or other unit. It is not an answer to how many units a person should take.
Check before splitting or opening
Before splitting, crushing, chewing or opening anything, find an explicit instruction for this exact product in its current label and ask a pharmacist. A score line or a previous pack is not enough by itself.
Put every product on one list
Include prescriptions, over-the-counter products, eye drops, creams, vitamins, minerals, herbs and supplements. A pharmacist or prescriber needs the whole list before any combination, alternation, switch or stop is considered.
Ask a specific pharmacogenetics question
Ask which medicine, which gene and what clinical decision a result could change. A gene–drug association does not mean broad genetic testing is needed for everyone and must not be used to change treatment without professional review.
Know when to seek urgent help
For a suspected overdose, a severe allergic reaction, fainting or difficulty breathing, use the local emergency or poison-information service now. Do not wait for a website reply or alter several medicines to test what caused it.
This card does not calculate a dose, decide whether medicines can be combined, or replace a clinician or pharmacist. Market-specific current labels and the person's full context still need review.
HOW IT WORKS · NOT A TREATMENT PLAN
How colchicine is described in the label: a tubulin-binding pathway, not an individual-use rule
- “Binds to tubulin” is a mechanism description in the label; it does not mean a webpage can decide whether pain, redness, diarrhoea, muscle symptoms or a laboratory change is caused by this medicine, gout or another cause.
- Medicines that also involve inflammation, joint pain, uric acid or cell processes cannot be self-combined, alternated, substituted or milligram-converted because their names, uses or mechanism terms seem similar. Have a pharmacist or prescribing team review every actual pack, prescription and supplement item by item.
- A mechanism explanation cannot decide when to start, how long to continue, whether to make up a missed use, whether to stop or how to handle an acute symptom. Any real-use question must return to current target-market information for the exact product and a professional.

How to read this record
Read each document in its stated market, date and dosage-form context. A historical record is not a current label and does not support individual medical, substitution or purchasing conclusions.
Keep international and mainland China records separate
This page has a U.S. public history/regulatory archive but no mainland China record for this specific product. That does not establish whether the medicine exists, is approved or is available in mainland China. Verify product identity, dosage form, strength, holder and the current label item by item.
RECORD FAQ
Record questions
Do COLCRYS 0.6 mg, an NDC and a 30-tablet bottle mean a person can self-start, adjust, split or change to another colchicine product?
No. These details only identify the exact tablet and bottle in the cited U.S. historical label. A shared generic name, nearby milligram number, package photo or score does not establish self-initiation, increase, repetition, splitting, stopping, co-use, alternation or substitution; take the current pack, prescription and complete medicine list to a pharmacist or prescribing team.
