Viagra Extra Dosage is a high-potency formulation of sildenafil citrate, specifically engineered for men with severe erectile dysfunction (ED) who have not achieved satisfactory results with standard-dose therapies. This prescription medication provides a robust pharmacological approach by enhancing nitric oxide-mediated vasodilation in the cavernosal arteries, facilitating significant penile blood flow necessary for achieving and maintaining erections. Clinical evidence supports its efficacy in cases of pronounced vasculogenic ED, offering a tailored solution under strict medical supervision. It is imperative that this medication be used only as directed by a qualified healthcare provider following a comprehensive cardiovascular and genitourinary assessment.

Common use

Viagra Extra Dosage is indicated for the treatment of erectile dysfunction in adult males. It is specifically reserved for cases where standard doses (e.g., 50 mg or 100 mg sildenafil) have yielded suboptimal therapeutic outcomes. It is not intended for use by women, adolescents, or individuals without a clinical diagnosis of ED. The medication does not protect against sexually transmitted infections and should not be used recreationally.

Dosage and direction

The recommended starting dose is 150 mg, taken approximately one hour prior to anticipated sexual activity. Based on efficacy and tolerability, the dose may be adjusted under medical supervision 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. Sexual stimulation is required for the medication to produce an erection.

Precautions

Prior to use, patients must disclose full medical history, including:

• History of cardiovascular diseases such as angina, heart failure, or arrhythmias
• Hypotension or hypertension
• Renal or hepatic impairment
• Anatomical deformation of the penis (e.g., Peyronie’s disease)
• Conditions predisposing to priapism (e.g., sickle cell anemia, multiple myeloma)
• Retinal disorders or hereditary degenerative retinal diseases

Avoid alcohol consumption, as it may increase the risk of hypotension and reduce efficacy.

Contraindications

Viagra Extra Dosage is contraindicated in patients:

• Using any form of organic nitrates or nitric oxide donors (e.g., nitroglycerin, isosorbide mononitrate)
• With a known hypersensitivity to sildenafil or any excipients in the formulation
• With severe hepatic impairment (Child-Pugh Class C)
• With hypotension (BP < 90/50 mmHg)
• Who have experienced non-arteritic anterior ischemic optic neuropathy (NAION) in the past

Possible side effects

Common adverse reactions may include:

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

Less frequently, patients may experience:

• Back pain or myalgia
• Priapism (prolonged and painful erection exceeding 4 hours—requires immediate medical attention)
• Sudden hearing loss or tinnitus
• Cardiovascular events (e.g., palpitations, syncope)

Drug interaction

Sildenafil is primarily metabolized by CYP3A4. Concomitant use with the following may require dose adjustment or avoidance:

• Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, clarithromycin)—dose reduction advised
• Alpha-blockers (e.g., doxazosin)—risk of symptomatic hypotension
• Antihypertensive agents—additive hypotensive effects possible
• Guanylate cyclase stimulators (e.g., riociguat)—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 extra tablets to make up for a missed opportunity.

Overdose

In cases of suspected overdose (e.g., ingestion exceeding 200 mg in 24 hours), seek immediate medical attention. Symptoms may include severe hypotension, syncope, prolonged erection, or visual disturbances. Supportive measures should be implemented, including cardiovascular monitoring and positional management for hypotension.

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.
