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 option provides a robust pharmacological approach to achieving and sustaining erections sufficient for sexual activity, operating through targeted inhibition of cyclic guanosine monophosphate (cGMP)-specific PDE5. Clinical evidence supports its efficacy in cases of pronounced endothelial dysfunction, diabetic ED, and post-prostatectomy erectile impairment, offering a scientifically validated solution where conventional therapies fall short. Medical supervision is imperative prior to initiation to ensure appropriate patient selection and risk mitigation.

Features

• Active ingredient: Sildenafil citrate 150 mg or 200 mg
• Pharmacological class: Phosphodiesterase type 5 (PDE5) inhibitor
• 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 (high-fat meals may delay absorption)
• Available formulations: Film-coated tablets for optimized bioavailability

Benefits

• Provides a potent therapeutic option for patients with severe erectile dysfunction unresponsive to lower sildenafil doses
• Enhances nitric oxide-mediated cavernosal smooth muscle relaxation, facilitating robust penile blood inflow
• Supports improved erectile hardness scores (EHS) and successful intercourse completion rates
• May restore sexual confidence and reduce anxiety related to performance in treatment-resistant cases
• Allows for flexible sexual spontaneity within the medication’s effective window
• Supported by extensive clinical data on sildenafil’s safety and mechanism of action

Common use

Viagra Extra Dosage is indicated for the treatment of erectile dysfunction in adult males. It is particularly suited for individuals who have previously used lower doses of sildenafil (e.g., 25 mg, 50 mg, or 100 mg) without achieving satisfactory erectile response. It is not indicated for use in women, adolescents, or men without erectile dysfunction. Sexual stimulation is required for the medication to produce an effect.

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 once daily. Do not exceed one dose in a 24-hour period. Tablets should be swallowed whole with a glass of water. Avoid consumption with grapefruit juice, as it may increase sildenafil concentrations and the risk of adverse effects.

Precautions

• Cardiovascular status should be assessed prior to prescribing; sexual activity poses potential cardiac risk
• Use with caution in patients with anatomical penile deformities, sickle cell anemia, multiple myeloma, or leukemia
• May cause hypotension; avoid in patients with hypotension or uncontrolled hypertension
• Not recommended for use with other ED treatments or recreational erectogenic agents
• Priapism (erection >4 hours) requires immediate medical intervention to avoid permanent damage
• Advise patients to avoid excessive alcohol consumption (may increase risk of orthostasis and reduce efficacy)

Contraindications

• Concomitant use of organic nitrates or nitric oxide donors in any form
• History of hypersensitivity to sildenafil or any component of the formulation
• Concurrent use of guanylate cyclase stimulators (e.g., riociguat)
• Severe hepatic impairment (Child-Pugh Class C)
• End-stage renal disease requiring dialysis
• Hereditary degenerative retinal disorders (e.g., retinitis pigmentosa)

Possible side effect

• Headache (15%–20%)
• Flushing (10%–15%)
• Dyspepsia (5%–7%)
• Nasal congestion (3%–5%)
• Dizziness (2%–4%)
• Visual disturbances (e.g., cyanopsia, blurred vision; 2%–3%)
• Back pain or myalgia (1%–2%)
• Less commonly: hypotension, hearing loss, non-arteritic anterior ischemic optic neuropathy (NAION)

Drug interaction

• Nitrates: Profound hypotension, contraindicated
• Alpha-blockers: Additive hypotensive effects; avoid concurrent use
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin): Increase sildenafil exposure; dose reduction recommended
• CYP3A4 inducers (e.g., rifampin): May reduce sildenafil efficacy
• Antihypertensives: Potential additive blood pressure-lowering effects
• Grapefruit juice: Inhibits CYP3A4, increasing sildenafil bioavailability

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 extra tablets to make up for a missed opportunity.

Overdose

Symptoms may include severe hypotension, syncope, prolonged erection, and visual disturbances. In case of suspected overdose, seek immediate medical attention. Supportive measures should be instituted, including supine positioning with legs elevated to stabilize blood pressure. Hemodialysis is not expected to significantly enhance elimination.

Storage

Store at room temperature (20°–25°C or 68°–77°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 100 mg sildenafil with limited success, my urologist recommended Viagra Extra Dosage. The 150 mg dose provided the rigidity I hadn’t experienced in years. No significant side effects beyond mild flushing.” — Verified Patient, 58

“As a cardiologist, I reserve this for select patients with severe ED and stable cardiovascular status. When used appropriately, it can significantly improve quality of life without compromising safety.” — Dr. Evans, MD

“Effective but requires careful timing. Taking it on an empty stomach made a noticeable difference in onset. Would not recommend without medical clearance.” — Verified Patient, 62
