What It Is and How It Works
Sildenafil is a medication categorized as a phosphodiesterase type 5 (PDE5) inhibitor. Its primary mechanism involves relaxing blood vessels, which enhances blood flow to specific areas of the body. For erectile dysfunction, it helps facilitate and maintain an erection by amplifying the effects of nitric oxide, a natural chemical released during sexual stimulation.
While it effectively alleviates the symptoms of erectile dysfunction, sildenafil does not cure the underlying causes or increase sexual desire. It is also not meant to serve as a form of male contraception.
Indications / Uses
The primary approved use of sildenafil is to treat erectile dysfunction. This medication helps men achieve and maintain an erection sufficient for sexual intercourse. It is important to note that sexual stimulation is required for sildenafil to be effective.
While sildenafil is sometimes used off-label for conditions like pulmonary arterial hypertension (under a different brand and dosage), this article focuses on its use for erectile dysfunction.
Dosage Forms and Typical Dosing Considerations
Sildenafil is available in several dosages, commonly ranging from 25mg to 100mg in tablet form. The 200mg dosage is not a standard recommendation and is typically considered when no response is seen at lower doses and with guidance from a healthcare professional.
Dosing may be influenced by a patient\’s age, kidney and liver function, and current medications. It is critical to adhere to healthcare professional’s prescription instructions to minimize the risk of adverse effects.
How to Take It Correctly Step-by-Step
To maximize the effectiveness of sildenafil:
- Take the tablet about one hour before planned sexual activity.
- Swallow the tablet whole with water. It can be taken with or without food, though a high-fat meal might delay onset.
- Avoid consuming large amounts of alcohol, which can impair performance.
- If a dose is missed, take it only when planning sexual activity. Do not double doses as this can increase risk of side effects.
- Store the medication in a cool, dry place away from moisture and light.

Caution is advised in individuals with cardiovascular conditions, severe liver impairment, or retinal disorders. Pregnant and breastfeeding women, and children should avoid the use of sildenafil unless directed by a healthcare provider.
Drug, Food, and Supplement Interactions
Sildenafil can interact with certain medications, including nitrates commonly used in heart conditions, leading to potentially severe blood pressure drops.
