This increases blood flow to the penis when a man is aroused, which improves sexual performance for men with erectile dysfunction (ED). For most men, the effects of Sildenafil can last for up to 4-5 hours, although it can range from 2-6 hours depending on the individual. Sildenafil can safely be used daily, if you’re intending to have sex daily, however, the effects of Sildenafil don’t accumulate if you take more in advance. Use it only when you need it.
