Viagra Extra Dosage represents a specialized formulation of sildenafil citrate, engineered for individuals with severe erectile dysfunction (ED) who have demonstrated inadequate response to standard-dose phosphodiesterase type 5 (PDE5) inhibitors. This higher-strength medication provides a potent therapeutic option, facilitating robust nitric oxide-mediated vasodilation within the corpus cavernosum to achieve and sustain erections sufficient for sexual activity. It is strictly indicated for use under medical supervision following a comprehensive cardiovascular and urological assessment. Adherence to prescribed dosing and contraindication screening is imperative to mitigate associated risks.

Common use

Viagra Extra Dosage is prescribed for the treatment of severe erectile dysfunction in adult males. It is specifically utilized in cases where lower doses (e.g., 25 mg, 50 mg, or 100 mg) of sildenafil have proven ineffective despite correct usage. It is not indicated for use by women, adolescents, or individuals without a clinical diagnosis of ED. The medication is intended for use prior to anticipated sexual activity and should not be taken more than once per day.

Dosage and direction

The recommended dose is one tablet taken orally approximately 30–60 minutes before sexual activity. Do not exceed one dose within a 24-hour period. Dosage must be individualized based on efficacy and tolerability, typically starting at 150 mg under physician supervision. Tablets should be swallowed whole with a glass of water. Sexual stimulation is required for the medication to be effective.

Precautions

• Prior to use, undergo a thorough medical evaluation to assess cardiovascular health.
• Not recommended for use in patients with severe hepatic impairment or end-stage renal disease.
• Avoid concomitant use with other erectile dysfunction treatments.
• Use with caution in patients with anatomical deformation of the penis or conditions predisposing to priapism.
• May cause dizziness or visual changes; exercise caution when driving or operating machinery.

Contraindications

• Concomitant use of organic nitrates or nitric oxide donors in any form.
• History of hypersensitivity to sildenafil or any component of the formulation.
• Patients with severe cardiovascular disorders, including unstable angina or heart failure.
• Retinitis pigmentosa or other hereditary retinal disorders.
• Recent history of stroke or myocardial infarction.

Possible side effects

Common side effects may include headache, flushing, dyspepsia, nasal congestion, and dizziness. Less frequently, visual disturbances (such as blurred vision or cyanopsia), hearing loss, or priapism (prolonged and painful erection lasting more than 4 hours) may occur. Seek immediate medical attention if an erection persists beyond 4 hours.

Drug interaction

Sildenafil is metabolized primarily by CYP3A4. Concomitant use with strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) may increase sildenafil concentrations. Concurrent administration with alpha-blockers may lead to symptomatic hypotension. Avoid use with other PDE5 inhibitors, guanylate cyclase stimulators, or recreational drugs containing nitrates.

Missed dose

Viagra Extra Dosage is not intended for regular daily dosing. If a dose is missed, it may be taken when remembered, provided it is at least 24 hours before the next anticipated sexual activity. Do not double the dose.

Overdose

In case of suspected overdose, seek immediate medical attention. Symptoms may include severe hypotension, syncope, prolonged erection, or visual disturbances. Standard supportive measures should be applied; hemodialysis is not expected to accelerate clearance.

Storage

Store at room temperature (15–30°C) in the original container. Protect from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
