Viagra, scientifically known as sildenafil, is a medication commonly prescribed to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, helping to achieve and maintain an erection in response to sexual stimulation. However, understanding the appropriate dosage of Viagra is crucial for its efficacy and safety.

4. Using Viagra Safely
It is imperative to follow your healthcare provider’s instructions regarding Viagra dosage. Never exceed the recommended dosage or frequency, as this can lead to serious health issues. Always inform your doctor about any other medications you are taking to avoid potential interactions.
