Quick Facts

- Common side effects include headache, flushing, and indigestion.

What It Is and How It Works
Sildenafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the enzyme PDE5, which results in the relaxation of smooth muscle and increased blood flow to specific areas of the body, such as the penis. During sexual stimulation, this enhanced blood flow facilitates the ability to achieve and maintain an erection.
While Sildenafil can help in achieving an erection when sexually stimulated, it does not increase sexual desire or cure ED permanently. It is important to note that Sildenafil’s efficacy requires sexual arousal as a part of its mechanism.
Indications / Uses
The primary approved use of Sildenafil is to treat erectile dysfunction in men. Erectile dysfunction is a common condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Sildenafil may also be prescribed for other purposes, such as treating pulmonary arterial hypertension (under a different brand name). The decision to use Sildenafil should be made in consultation with a healthcare professional to ensure it is appropriate for the individual\’s specific circumstances.
Dosage Forms and Typical Dosing Considerations
Sildenafil is commonly available in oral tablets with varying strengths, typically ranging from 25 mg to 100 mg. The appropriate dose depends on the individual\’s health status, severity of dysfunction, and responsiveness to treatment. It is typically taken as needed about one hour before sexual activity, and not more than once per day.
Factors such as age, pre-existing medical conditions (like liver or kidney impairment), and other medications can influence the dosage. It\’s critical to follow the healthcare provider’s dosing recommendations and not adjust doses without consulting them.
How to Take It Correctly Step-by-Step
Sildenafil should be taken as prescribed by your doctor. Follow these general steps:
- Take the tablet as directed, usually about an hour before planned sexual activity.
- It can be taken with or without food, though high-fat meals may delay its effect.
- If you miss a dose, take it when you remember, but do not double doses.
- Store tablets at room temperature away from moisture and heat.
- Do not mix with alcohol, as it can increase side effects.
- Avoid using with nitrates or other potent cardiovascular drugs without doctor\’s approval.
