Avana 100 mg contains avanafil, a PDE-5 inhibitor used to treat erectile dysfunction (ED). It works by improving blood flow to the penis during sexual stimulation. The recommended starting dose of avanafil is 100 mg taken as needed, approximately 15 minutes before sexual activity, and it should not be taken more than once daily. Better sexual health involves more than medication. Regular physical activity, maintaining a healthy weight, eating a balanced diet, getting adequate sleep, managing stress, avoiding tobacco, and limiting excessive alcohol can support cardiovascular health and erectile function. Addressing anxiety, relationship difficulties, or other psychological factors may also improve sexual wellbeing.
