Colchicine for Gout Treatment: Uses, Dosage & Side Effects
Colchicine is a fast-acting medication that helps reduce inflammation during acute gout attacks and can help prevent flare-ups when used as part of a comprehensive treatment plan.
Colchicine is a fast-acting medication that helps reduce inflammation during acute gout attacks and can help prevent flare-ups when used as part of a comprehensive treatment plan.
Colchicine works by interfering with the inflammatory response that occurs when uric acid crystals are present in a joint. It specifically prevents white blood cells from migrating to the inflamed area and releasing inflammatory chemicals.
Unlike medications that lower uric acid levels, colchicine treats the pain and inflammation of an active gout attack but does not affect the underlying cause.
Colchicine is typically used in two different ways for gout:
The current recommended dosing for an acute gout attack is 1.2 mg (two 0.6 mg tablets) at the first sign of a flare, followed by 0.6 mg one hour later.
This lower-dose regimen has been shown to be as effective as previous higher-dose protocols while causing fewer side effects.
For preventing gout flares, especially during the first months of uric acid-lowering therapy, a lower dose of 0.6 mg once or twice daily is often prescribed.
This preventative approach may continue for 3-6 months or longer while uric acid levels stabilize.
While effective, colchicine can cause significant side effects, particularly gastrointestinal issues:
Important Warning:
Colchicine has a narrow therapeutic window—the difference between an effective dose and a toxic dose is small. Never take more than prescribed, and be aware of potential drug interactions that can increase toxicity.
Colchicine is highly effective when used appropriately:
Colchicine is a flare-stopper. It's not about lowering uric acid—that's a different job. Colchicine helps reduce the inflammation caused when uric acid crystals suddenly jab into your joints, often in the middle of the night. It's most effective if taken at the first sign of a flare.
Colchicine calms the chaos. When urate crystals trigger an immune reaction, white blood cells rush in, inflaming the joint. Colchicine steps in and tells those cells to stand down—reducing swelling, redness, and pain. It doesn't dissolve the crystals, but it quiets the body's overreaction.
If you catch a flare early—within the first 12–24 hours—colchicine can start to reduce pain in a few hours. That said, it's not an instant fix. It may take a day or two to feel back to normal. Think of it more like slowing a runaway train than flipping a switch.
Most adults take 1.2 mg (that's two tablets) at the first sign of a flare, then 0.6 mg one hour later. That's it—then stop. Taking more doesn't help and may cause unpleasant side effects. Always follow your doctor's instructions because dosing can change based on kidney function and other factors.
The most common side effect is diarrhea—and not the subtle kind. Nausea, vomiting, and stomach cramps can also happen, especially at higher doses. Rarely, colchicine can affect your blood counts or muscles if taken long-term or at high doses. It's powerful, so use it carefully.
Yes—but only as part of a bigger plan. While not a long-term fix, low-dose colchicine (like 0.6 mg once or twice daily) is often prescribed during the first few months of starting a uric acid–lowering medication like allopurinol. It helps prevent flares during that bumpy transition period.
Usually, yes. Colchicine is often used alongside uric acid–lowering drugs (like allopurinol or febuxostat) and sometimes NSAIDs. But drug interactions do exist—especially with medications that affect liver enzymes or kidney function. Always keep your care team in the loop.
Avoid grapefruit juice (seriously—it can mess with how your body handles colchicine), and watch for certain antibiotics or antifungals that can raise colchicine levels dangerously high. Also avoid taking more than prescribed—more is not better here.
If you have severe kidney or liver disease—or are taking certain interacting drugs—colchicine may not be safe. And if you've already taken your dose for a flare, don't redose for at least 3 days, even if the pain persists. In some cases, alternatives like NSAIDs or steroids are better.
Not in the U.S. Colchicine requires a prescription because it's potent and can be dangerous if misused. If you're flaring and don't yet have a prescription, talk to a provider—fast. Timing matters with this drug.
