What Is Sildenafil for Erectile Dysfunction?

Sildenafil for erectile dysfunction refers to the use of sildenafil citrate, a prescription medication designed to improve the ability to achieve and maintain an erection suitable for sexual activity. Sildenafil is the active ingredient in Viagra but is also available as a generic medication.

It works by increasing blood flow to the penis in response to sexual stimulation. Sildenafil does not increase libido but supports the natural erectile response. It is one of the most widely studied and commonly prescribed ED medications for men of all ages.

Key Takeaways

• Sildenafil enhances blood flow to support erections but does not increase sexual desire.
• Generic sildenafil is clinically identical to Viagra, though often more affordable.
• Typical sildenafil dosage ranges from 25 mg to 100 mg depending on health status and response.
• Sildenafil side effects are usually mild and temporary but can include headache or flushing.
• Men taking nitrates for heart conditions should never use sildenafil.
• The medication should be taken 30 to 60 minutes before sexual activity.
• Buying sildenafil online should be done through licensed pharmacies only.
• Sildenafil is also used for pulmonary hypertension at different doses.
• Proper evaluation by a clinician is recommended before starting sildenafil.
• Lifestyle factors like stress, alcohol, and sleep can influence how well sildenafil works.

Quick Facts About Sildenafil

How Does Sildenafil Work?

Sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 breaks down a chemical called cyclic guanosine monophosphate (cGMP), which helps relax smooth muscle tissue in the penis. When sildenafil blocks PDE5, cGMP levels stay elevated longer.

As a result, blood vessels in the penis remain more relaxed, allowing improved blood flow during sexual arousal. Sildenafil only works alongside sexual stimulation; it does not create spontaneous erections.

Common Sildenafil Uses

• Erectile dysfunction treatment
• Improved erectile firmness and duration
• Treatment of pulmonary arterial hypertension (under brand name Revatio)
• Off-label use for performance anxiety-related ED when medically appropriate

Sildenafil Dosage

The most common sildenafil dosage options for ED include:

• 25 mg
• 50 mg (most common starting dose)

Men should only adjust dosage under medical supervision. Higher doses do not guarantee better results and may increase side effects.

Factors affecting dosage

• Age
• Cardiovascular health
• Other medications
• Severity of ED
• Frequency of use
• Liver or kidney health
