Viagra Extra Dosage represents a high-potency formulation of sildenafil citrate, specifically engineered for men with severe erectile dysfunction (ED) who have demonstrated inadequate response to standard-dose phosphodiesterase type 5 (PDE5) inhibitors. This enhanced dosage provides a robust pharmacological approach to achieving and sustaining erections sufficient for sexual activity, leveraging well-established mechanisms of action with increased bioavailability. It is intended for use under strict medical supervision, following comprehensive cardiovascular and anatomical assessment to ensure patient suitability and mitigate associated risks.
Features
- Active ingredient: Sildenafil citrate 150 mg or 200 mg
- Pharmaceutical class: Selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5)
- Onset of action: Approximately 30–60 minutes post-administration
- Duration of effect: Up to 4–6 hours
- Administration: Oral tablet, taken with or without food (though high-fat meals may delay absorption)
- Available by prescription only
Benefits
- Provides a higher degree of penile vasodilation for patients non-responsive to standard doses
- Enhances the rigidity and sustainability of erections during sexual stimulation
- Supports improved sexual confidence and relationship satisfaction
- Reduces anxiety related to sexual performance in appropriately selected patients
- Offers a proven therapeutic alternative before considering more invasive treatments
Common use
Viagra Extra Dosage is indicated for the treatment of erectile dysfunction in adult males. It is specifically reserved for individuals who have previously tried and failed to achieve satisfactory results with lower doses of sildenafil (e.g., 25 mg, 50 mg, or 100 mg). It is not intended for use in women, children, or individuals without erectile dysfunction. Sexual stimulation is required for the medication to produce an erection.
Dosage and direction
The recommended starting dose is 150 mg, taken approximately 30–60 minutes before anticipated sexual activity. Based on efficacy and tolerability, the dose may be increased to a maximum of 200 mg per 24-hour period. Do not exceed one dose per day. Tablets should be swallowed whole with a glass of water. Avoid consuming grapefruit or grapefruit juice, as it may interfere with metabolism and increase side effects.
Precautions
- A comprehensive medical history and physical examination should be conducted prior to initiation to rule out cardiovascular instability, anatomical deformities, or conditions that would predispose the patient to priapism.
- Use with caution in patients with bleeding disorders, active peptic ulceration, or retinitis pigmentosa.
- Not recommended for use in patients with severe hepatic impairment (Child-Pugh class C) or severe renal impairment (creatinine clearance <30 mL/min).
- May cause hypotension; avoid in patients with hypotension or uncontrolled hypertension.
- Patients should be advised to avoid excessive alcohol consumption, which may increase the risk of adverse effects.
Contraindications
- Concomitant use with organic nitrates or nitric oxide donors in any form.
- History of hypersensitivity to sildenafil or any component of the formulation.
- Concurrent use with guanylate cyclase stimulators such as riociguat.
- Patients with hereditary degenerative retinal disorders.
- Men for whom sexual activity is inadvisable due to underlying cardiovascular pathology.
Possible side effects
Common side effects may include:
- Headache
- Flushing
- Dyspepsia
- Nasal congestion
- Dizziness
- Visual disturbances (e.g., changes in color perception, blurred vision)
Less common but serious side effects require immediate medical attention:
- Priapism (prolonged erection >4 hours)
- Sudden hearing loss
- Severe hypotension
- Acute visual field defects
- Symptoms of cardiovascular events (e.g., chest pain, shortness of breath)
Drug interaction
Sildenafil is primarily metabolized by CYP3A4 and CYP2C9. Concomitant use with the following may require dose adjustment or avoidance:
- Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, clarithromycin) – may significantly increase sildenafil exposure.
- Alpha-blockers (e.g., doxazosin, tamsulosin) – may potentiate hypotensive effects.
- Antihypertensive medications – additive blood pressure-lowering effects.
- Other PDE5 inhibitors – concurrent use is contraindicated.
Missed dose
Viagra Extra Dosage is taken on an as-needed basis. There is no dosing schedule; therefore, the concept of a “missed dose” does not apply. Do not take an additional tablet to make up for a missed opportunity.
Overdose
In cases of overdose, standard supportive measures should be employed. Expected effects may include severe hypotension, syncope, and prolonged erection. Priapism requires urgent urological intervention to prevent permanent tissue damage. Hemodialysis is not expected to significantly accelerate elimination due to high protein binding.
Storage
Store at room temperature (15–30°C or 59–86°F) 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.

Reviews
“After trying multiple standard doses with limited success, my physician recommended Viagra Extra Dosage. The difference was significant—finally, a reliable response. I experienced mild flushing, but it was manageable.” – Verified patient, 58
“As a urologist, I reserve this formulation for carefully selected patients with demonstrated hyporesponsiveness. In appropriate candidates, it can markedly improve outcomes without escalating to second-line therapies.” – Dr. A. Reynolds, MD
“Effective but potent. I advise my patients to start low and only increase if necessary. The risk of side effects is dose-dependent, so patient education is critical.” – Clinical Pharmacist, specialized in men’s health
