Viagra, known generically as sildenafil, is a widely recognized medication used to treat erectile dysfunction (ED) in men. By inhibiting phosphodiesterase type 5 (PDE5), sildenafil increases blood flow to the penis during sexual stimulation, which helps to achieve and maintain an erection.
Viagra is intended for use only upon a doctor’s prescription and should not be used in conjunction with certain other medications, particularly those used to treat chest pain. Always consult with a healthcare provider to ensure it is safe based on your health and other medications.
