Sildenafil 200mg – Erectile Dysfunction (ED)

Sildenafil, widely known by the brand name Viagra, is a PDE5 inhibitor used to treat erectile dysfunction (ED) in adult men. It works by increasing blood flow to the penis during sexual stimulation, helping support the ability to achieve and maintain an erection.

Sildenafil does not automatically produce an erection or increase sexual desire. Sexual stimulation is required for the medication to work.

HOW DOES SILDENAFIL WORK?

Sildenafil inhibits an enzyme known as phosphodiesterase type 5 (PDE5). This enhances the nitric oxide signaling involved in relaxing blood vessels and increasing blood flow to the penis during sexual stimulation.

Effects generally begin within 30–60 minutes, although response times can vary depending on the individual, food intake, medications, and other factors.

KEY CHARACTERISTICS

Established ED Medication

Sildenafil is a widely used prescription treatment for erectile dysfunction and has an established clinical history.

Supports Erectile Function

By improving penile blood flow during sexual stimulation, sildenafil can help men with ED achieve and maintain an erection.

Convenient Oral Administration

Sildenafil is taken orally, making it a convenient treatment option when prescribed appropriately.

Duration of Action

Its effects commonly remain clinically useful for approximately 4 hours, although this does not mean an erection will persist for that entire period.

IMPORTANT DOSAGE INFORMATION

200mg is higher than the FDA-labeled maximum recommended dose of sildenafil for erectile dysfunction, which is 100mg taken no more than once per day.

Higher doses can increase the likelihood of adverse effects and should not be taken unless specifically directed by a qualified healthcare professional.

Sildenafil must not be combined with nitrate medications because this can cause a dangerous decrease in blood pressure.

POSSIBLE SIDE EFFECTS

Common side effects may include:

• Headache
• Flushing
• Indigestion
• Nasal congestion
• Dizziness
• Temporary visual disturbances

Seek urgent medical attention for chest pain, sudden loss of vision or hearing, or an erection lasting longer than four hours.

CONCLUSION

Sildenafil is an established PDE5 inhibitor for treating erectile dysfunction. It supports erectile function by increasing penile blood flow in response to sexual stimulation.

Because a 200mg strength exceeds the standard maximum recommended ED dose, medical supervision is particularly important. Always follow the dosage prescribed by a qualified healthcare professional and review possible medication interactions and health risks before use.
