Plan B for athletes: anti-doping and performance
Athletes in regulated competitive sport face an additional layer of medication review beyond clinical considerations: whether Plan B (Levonorgestrel) is permitted under anti-doping rules, requires a Therapeutic Use Exemption, or is on the prohibited list at 1.5mg. The active ingredient Levonorgestrel determines the answer; brand or generic version is irrelevant to anti-doping classification.
Anti-doping status of Plan B
The WADA Prohibited List and equivalent national lists are updated annually. Levonorgestrel 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. Plan B's primary mechanism is delaying or preventing ovulation when taken before the LH surge.
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 Plan B at 1.5mg.
Frequently asked questions
Is Plan B banned in sport? ▾
Whether Plan B is banned depends on Levonorgestrel and the most recent WADA Prohibited List. Some agents are permitted, some restricted in-competition, some prohibited at all times. Always check the current list and TUE requirements before competition.
Will Plan B 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 1.5mg. Athletes should expect to experiment with timing relative to training in the first weeks.
