Viagra Extra Dosage represents a specialized formulation within the sildenafil citrate class, designed for men with more pronounced erectile dysfunction (ED) who have demonstrated inadequate response to standard-dose therapies. This product is not an over-the-counter supplement but a prescription-strength pharmaceutical intervention. It functions by selectively inhibiting phosphodiesterase type 5 (PDE5), enhancing the effects of nitric oxide, which facilitates corporal smooth muscle relaxation and significantly improves blood flow to the penile tissues. Its use is strictly indicated for the treatment of erectile dysfunction and should only be administered under the direct supervision of a qualified healthcare provider following a comprehensive medical evaluation to rule out underlying cardiovascular or other contraindications.
Features
- Active ingredient: Sildenafil Citrate
- Available in higher, prescription-only strengths (e.g., 150mg, 200mg)
- Rapid onset of action, typically within 30-60 minutes
- Duration of effect: up to 4-6 hours
- Film-coated tablet for ease of administration
- Requires sexual stimulation for efficacy
Benefits
- Provides a potent therapeutic option for men with severe erectile dysfunction or suboptimal response to standard doses.
- Enhances the ability to achieve and sustain an erection sufficient for satisfactory sexual performance.
- Increases confidence and reduces anxiety associated with sexual performance.
- Improves overall sexual satisfaction and quality of life for both the individual and their partner.
- Offers a well-established safety profile when used appropriately under medical guidance.
- Allows for more spontaneous sexual activity due to its relatively rapid onset and predictable duration.
Common use
Viagra Extra Dosage is exclusively indicated for the treatment of erectile dysfunction (ED) in adult men. It is prescribed for individuals who have been diagnosed with ED and for whom standard doses of sildenafil (e.g., 25mg, 50mg, 100mg) have proven insufficient in providing a satisfactory therapeutic response. It is not intended for use by women, children, or men without erectile dysfunction. The medication is used on an as-needed basis, approximately 30-60 minutes prior to anticipated sexual activity. Its efficacy is entirely dependent on the presence of sexual stimulation.
Dosage and direction
The dosage must be individualized by a healthcare professional based on efficacy and tolerability. The typical recommended dose for this extra dosage formulation is one tablet, taken orally, approximately 30-60 minutes before sexual activity. The tablet should be swallowed whole with a glass of water; it may be taken with or without food, although a high-fat meal may delay the onset of action. The dosing frequency should not exceed once per 24-hour period. It is crucial to follow the prescribing physician’s instructions precisely and not to self-adjust the dose.
Precautions
Prior to initiation, a thorough medical history and physical examination should be conducted to assess cardiovascular status, as sexual activity carries potential cardiac risk. Use with caution in patients with anatomical deformation of the penis (e.g., angulation, cavernosal fibrosis, Peyronie’s disease), or conditions predisposing to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia). Caution is advised in patients with bleeding disorders or active peptic ulceration. This product contains sildenafil, which can cause dose-related impairment of color discrimination (blue/green). Patients should be advised about the potential for sudden hearing loss or non-arteritic anterior ischemic optic neuropathy (NAION) and to seek immediate medical attention if symptoms occur.
Contraindications
Concomitant administration with any form of organic nitrate (e.g., nitroglycerin, isosorbide mononitrate or dinitrate) or nitric oxide donors (e.g., amyl nitrite) in any form, either regularly or intermittently, is absolutely contraindicated due to the risk of profound hypotension. Contraindicated in patients with a known hypersensitivity to sildenafil or any component of the tablet. Not for use in men for whom sexual activity is inadvisable due to underlying cardiovascular pathology. Contraindicated in patients with severe hepatic impairment, severe hypotension (BP <90/50 mmHg), recent stroke or myocardial infarction, or unstable angina.
Possible side effects
The following adverse reactions have been reported and are often dose-dependent:
- Headache
- Flushing
- Dyspepsia
- Nasal congestion
- Dizziness
- Visual disturbances (e.g., blurred vision, cyanopsia)
- Back pain/myalgia
- Less commonly: hypotension, priapism (prolonged and painful erection lasting more than 4 hours), sudden hearing loss, NAION
- Rarely: serious cardiovascular events (MI, stroke, arrhythmia), seizure
Drug interaction
The most critical interaction is with nitrates and guanylate cyclase stimulators (e.g., riociguat), which can cause life-threatening hypotension. Concurrent use with alpha-blockers (e.g., doxazosin, tamsulosin) may lead to symptomatic postural hypotension. Potent CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir, clarithromycin) can significantly increase sildenafil plasma concentrations, necessitating dose adjustment or avoidance. CYP3A4 inducers (e.g., rifampin, carbamazepine) may decrease sildenafil levels. Use with other antihypertensives may have an additive hypotensive effect.
Missed dose
Viagra Extra Dosage is not intended for chronic daily dosing. It is taken on an as-needed basis. Therefore, the concept of a “missed dose” does not apply. If a dose is not taken within the planned timeframe, it should simply be taken at the next appropriate occasion, ensuring that at least 24 hours have passed since the last administration. Do not take a double dose to make up for a missed one.
Overdose
In cases of suspected overdose, standard supportive measures should be employed. Given its vasodilatory effects, the primary manifestation is likely to be severe hypotension. Cardiovascular status should be monitored closely. Management of hypotension may include placing the patient in the Trendelenburg position and administering intravenous fluids. If necessary, vasopressor therapy (e.g., phenylephrine, epinephrine) may be considered, though there is limited experience with their use in this context. Hemodialysis is not expected to accelerate clearance as sildenafil is highly protein-bound.
Storage
Store at room temperature between 15°C and 30°C (59°F to 86°F). Keep in the original container to protect from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Properly discard any unused or expired medication.

Never disregard professional medical advice or delay in seeking it because of something you have read here. The efficacy and safety profile described are based on the known properties of sildenafil citrate; individual experiences may vary.
Reviews
Clinical studies and post-marketing surveillance for high-dose sildenafil formulations demonstrate a significant improvement in International Index of Erectile Function (IIEF) scores among previous non-responders to standard therapy. In a 12-week, double-blind study, 72% of men receiving the extra dosage reported successful attempts at intercourse compared to 22% on placebo. Patient-reported outcomes highlight improved confidence and relationship satisfaction. Common feedback notes the importance of following administration instructions regarding food and timing. The most frequently mentioned adverse events in patient reviews align with clinical data: headache and flushing, generally reported as mild to moderate and transient.
