Viagra, known generically as sildenafil, is a medication commonly prescribed for the treatment of erectile dysfunction (ED). It helps increase blood flow to the penis, enabling a man to achieve and maintain an erection during sexual activity. However, knowing the correct dosage is essential for its effectiveness and safety.
