Not banned by WADA: Sildenafil is not on the World Anti-Doping Agency (WADA) prohibited list, though its use in sport has been studied. Possible side effects during training or competition: Headache Flushing Dizziness Nasal congestion Indigestion Temporary vision changes These effects could interfere with athletic performance or increase the risk of accidents during intense exercise. Heart and blood pressure considerations: Sildenafil can lower blood pressure.
