Viagra Extra Dosage is a prescription medication specifically formulated for men experiencing severe erectile dysfunction (ED) who have not achieved satisfactory results with standard-dose therapies. This higher-strength formulation contains sildenafil citrate, a potent phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis to facilitate and maintain an erection sufficient for sexual activity. It is intended for use only under strict medical supervision, following a comprehensive evaluation of cardiovascular health and individual response to prior treatments. Patients must adhere to prescribed dosing guidelines to maximize efficacy while minimizing potential risks.

Common use

Viagra Extra Dosage is prescribed for the treatment of erectile dysfunction in adult men. It is specifically indicated for patients who have demonstrated inadequate response to maximum standard doses of sildenafil (e.g., 100 mg) or equivalent PDE5 inhibitors, as assessed by a healthcare provider. It is not intended for use by women, children, or individuals without a diagnosis of ED. Sexual stimulation is required for the medication to produce an erection.

Dosage and direction

The recommended dose is one tablet taken approximately 30–60 minutes before anticipated sexual activity. Do not exceed one dose within a 24-hour period. Swallow the tablet whole with a glass of water; breaking, crushing, or chewing is not advised. Dosage must be individualized based on efficacy and tolerability—always follow the exact prescription provided by your physician. Avoid consuming grapefruit or grapefruit juice, as it may increase sildenafil levels and the risk of adverse effects.

Precautions

• Prior to use, disclose full medical history, especially concerning cardiovascular conditions, stroke, heart attack, irregular heartbeats, or angina.
• Notify your doctor of any history of vision or hearing problems, bleeding disorders, stomach ulcers, or liver/kidney disease.
• Use caution when rising quickly from a sitting or lying position due to potential blood pressure changes.
• Avoid alcohol consumption, as it may increase side effects such as dizziness or lowered blood pressure.
• This medication does not protect against sexually transmitted infections.

Contraindications

Viagra Extra Dosage is contraindicated in patients:

• Using any form of organic nitrates (e.g., nitroglycerin, isosorbide mononitrate/dinitrate) or nitric oxide donors.
• With a known hypersensitivity to sildenafil or any component of the formulation.
• Who have been advised against sexual activity due to cardiovascular risk.
• With severe hepatic impairment, hypotension, or recent stroke or myocardial infarction.
• Taking riociguat, a guanylate cyclase stimulator.

Possible side effects

Common side effects may include:

• Headache
• Flushing
• Dyspepsia
• Nasal congestion
• Dizziness
• Visual disturbances (e.g., blurred vision, color tinge)

Less common but serious side effects require immediate medical attention:

• Prolonged erection (priapism) lasting more than 4 hours
• Sudden vision or hearing loss
• Chest pain, irregular heartbeat, or shortness of breath
• Severe dizziness or fainting
• Allergic reactions (rash, itching, swelling)

Drug interaction

Sildenafil may interact with:

• Nitrates and nitric oxide donors: Risk of severe hypotension.
• Alpha-blockers: Additive blood pressure-lowering effects.
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin): May increase sildenafil concentrations.
• Antihypertensives: Potential enhanced hypotensive effect.
• Grapefruit juice: Can elevate sildenafil levels.

Always inform your healthcare provider of all medications, including over-the-counter drugs and supplements.

Missed dose

This medication is taken on an as-needed basis; there is no daily dosing schedule. If you miss a planned dose, it may be taken later if adequate time remains before sexual activity, but never exceed one dose in 24 hours.

Overdose

In case of suspected overdose, seek immediate medical attention or contact a poison control center. Symptoms may include severe headache, visual disturbances, dizziness, fainting, or prolonged erection. Supportive measures and symptomatic treatment are standard; hemodialysis is not expected to significantly enhance elimination.

Storage

Store at room temperature (15–30°C or 59–86°F) in the original container, away from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
