Acyclovir for athletes: anti-doping and performance
Athletes in regulated competitive sport face an additional layer of medication review beyond clinical considerations: whether Acyclovir (Acyclovir) is permitted under anti-doping rules, requires a Therapeutic Use Exemption, or is on the prohibited list at 200mg, 400mg, 800mg. The active ingredient Acyclovir determines the answer; brand or generic version is irrelevant to anti-doping classification.
Anti-doping status of Acyclovir
The WADA Prohibited List and equivalent national lists are updated annually. Acyclovir 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. Acyclovir is a guanosine analogue selectively phosphorylated by viral thymidine kinase to its monophosphate form, then by cellular kinases to acyclovir triphosphate.
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 Acyclovir at 200mg, 400mg, 800mg.

Will Acyclovir 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 200mg, 400mg, 800mg.
