Published August 1, 2025 · 7 min read · Updated April 2026

Reviewed for accuracy by licensed clinical professionals.

Kratom withdrawal resembles mild to moderate opioid withdrawal because kratom acts on opioid receptors. Severity depends on dose, duration, and frequency of use.

Symptoms

Muscle aches and pain. Insomnia. Irritability and anxiety. Nausea, vomiting, and diarrhea. Runny nose and watery eyes. Sweating. Cravings. Depression and mood swings.

Timeline

Onset: 12-24 hours after last dose. Peak: days 2-4. Acute phase: 5-7 days. Post-acute symptoms (insomnia, mood changes) may persist 2-4 weeks.

Treatment

No FDA-approved medication for kratom withdrawal. Comfort medications include OTC pain relievers, anti-diarrheal agents, and sleep aids. Some clinicians use short courses of buprenorphine for severe cases. Tapering by gradually reducing dose over 1-2 weeks is an alternative to cold-turkey cessation.
