Sildenafil

Product Overview

Sildenafil is a prescription medication primarily used to treat erectile dysfunction (ED) in men. It belongs to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors.

Sildenafil works by improving blood flow to specific areas of the body, particularly the penis, when sexually stimulated.

At Angel Pharmacy, Sildenafil Tablets are supplied as commercially manufactured products in accordance with your doctor’s prescription.

What Sildenafil Is Used For

Erectile Dysfunction (ED)

Sildenafil is commonly prescribed to:

• Improve the ability to achieve an erection
• Maintain an erection sufficient for sexual activity
• Enhance sexual confidence in men with ED

It does not increase sexual desire and requires sexual stimulation to be effective.

Pulmonary Arterial Hypertension (Specialist Use)

In certain cases, Sildenafil may also be prescribed at specific doses for pulmonary arterial hypertension (PAH). This use is managed by a specialist.

How Sildenafil Works

During sexual stimulation, nitric oxide is released in the body, which helps relax blood vessels in the penis.

Sildenafil enhances this process by:

• Inhibiting the PDE5 enzyme
• Increasing blood flow to the penis
• Supporting a natural erectile response

It does not cause an automatic erection and only works with sexual arousal.

Directions for Use

Take exactly as prescribed by your doctor.

General guidance for erectile dysfunction:

• Usually taken 30–60 minutes before sexual activity
• Effects may last up to 4–6 hours
• Swallow tablet whole with water
• May be taken with or without food

Avoid heavy or high-fat meals before taking, as they may delay absorption.

Do not take more than one dose in a 24-hour period unless directed by your doctor.

Important Safety Information

• Heart disease
• Low or uncontrolled high blood pressure
• History of stroke or heart attack
• Liver or kidney disease
• Vision disorders
• Bleeding disorders

Sildenafil must not be taken with nitrate medications (commonly used for chest pain), as this can cause a dangerous drop in blood pressure.
