Montelukast for athletes: anti-doping and performance
Athletes in regulated competitive sport face an additional layer of medication review beyond clinical considerations: whether Montelukast (Montelukast) is permitted under anti-doping rules, requires a Therapeutic Use Exemption, or is on the prohibited list at 4mg, 5mg, 10mg. The active ingredient Montelukast determines the answer; brand or generic version is irrelevant to anti-doping classification.
Anti-doping status of Montelukast
The WADA Prohibited List and equivalent national lists are updated annually. Montelukast may be permitted at all times, prohibited in-competition only, prohibited at all times, or require a TUE depending on the agent and the sport. Some otherwise-routine medications are restricted at competition because of their pharmacological effects on cardiovascular, neuromuscular or hormonal systems. Montelukast selectively blocks the CysLT1 receptor, which mediates the action of leukotrienes C4, D4 and E4 — proinflammatory mediators released by mast cells and eosinophils in the airway.
TUE and practical guidance
According to anti-doping authorities, an athlete who needs a prohibited or restricted medication for a legitimate medical reason can apply for a Therapeutic Use Exemption before using it. The application requires medical documentation and may need to be approved before competition. Athletes should always check the most recent WADA list and their sport's federation rules before starting Montelukast at 4mg, 5mg, 10mg.

Will Montelukast affect my performance? ▾
Performance effects depend on the medication and the sport. Some medications can mildly impair physical or cognitive performance through their side effects; others are essentially neutral at 4mg, 5mg, 10mg. Athletes should expect to experiment with timing relative to training in the first weeks.
