What is the recommended starting dose of Sildenafil for erectile dysfunction?

  1. 100 mg

  2. 50 mg

  3. 25 mg

  4. 10 mg

The correct answer is: 50 mg

For the treatment of erectile dysfunction, the recommended starting dose of Sildenafil is 50 mg. This dose is generally effective for most patients and can be adjusted based on individual response and tolerability. Starting with a lower dose like 25 mg or 10 mg may not provide sufficient efficacy, while starting with a higher dose like 100 mg may increase the risk of adverse effects without additional benefit. Therefore, the starting dose of 50 mg strikes a balance between efficacy and safety for most patients.
