Sildenafil, commonly known by its brand name Viagra, is a medication primarily used to treat erectile dysfunction (ED) in men. Understanding the correct dosage and proper usage is crucial for achieving optimal results while minimizing potential risks. This comprehensive guide provides essential information about how to use sildenafil safely and effectively.
What is Sildenafil?
Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to certain areas of the body, helping men achieve and maintain erections when sexually stimulated. While best known for treating ED, sildenafil is also prescribed for pulmonary arterial hypertension under different brand names.
Standard Sildenafil Dosages
Sildenafil comes in three main strengths:
- 25 mg: Often prescribed for men who may be more sensitive to medication or have health conditions
- 50 mg: The most common starting dose for many patients
- 100 mg: The maximum recommended dose for those who don’t respond adequately to lower doses
Important Note: Your healthcare provider will determine the appropriate dosage based on your medical history, overall health, and response to treatment.
How to Take Sildenafil Correctly

- Take sildenafil approximately 30-60 minutes before sexual activity
