Viagra (sildenafil citrate) is a prescription phosphodiesterase type 5 (PDE5) inhibitor, clinically proven for the treatment of erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection when sexually stimulated. This medication has been a trusted solution for millions of men worldwide since its approval, offering a well-understood mechanism of action and a predictable safety profile under appropriate medical guidance.
Features

- Available in 25 mg, 50 mg, and 100 mg oral tablets
- Onset of action typically within 30–60 minutes
- Duration of effect up to 4–5 hours
- Requires sexual stimulation for efficacy
- FDA-approved for erectile dysfunction
Benefits

Common use
Viagra is primarily prescribed for the treatment of erectile dysfunction (ED) in adult men. Erectile dysfunction is defined as the consistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. It may be used by men with ED of various origins, including physiological causes (such as vascular disease, diabetes, or prostate surgery) and psychological factors, though organic causes typically respond best. It is not indicated for use by women, children, or men without erectile dysfunction.
Dosage and direction
The recommended starting dose for most patients is 50 mg taken approximately one hour before anticipated sexual activity. Based on efficacy and tolerability, the dose may be increased to a maximum of 100 mg or decreased to 25 mg. Do not take more than one dose in a 24-hour period. Viagra should be taken orally with or without food; however, high-fat meals may delay absorption and onset of action. Sexual stimulation is required for the medication to be effective.
Precautions
- Not for use by women or individuals under 18 years of age.
- Use with caution in patients with cardiovascular disease; sexual activity poses a potential cardiac risk.
- Avoid consumption of grapefruit or grapefruit juice, as it may increase sildenafil concentrations.
- Priapism (prolonged and painful erection lasting more than 4 hours) requires immediate medical attention to prevent permanent damage.
- Inform your healthcare provider of all medical conditions, especially heart problems, stroke, retinal disorders, kidney or liver impairment, bleeding disorders, or stomach ulcers.
Contraindications
- Concomitant use with any form of organic nitrates (e.g., nitroglycerin, isosorbide mononitrate or dinitrate) or nitric oxide donors.
- Hypersensitivity to sildenafil or any component of the formulation.
- Concurrent use with guanylate cyclase stimulators, such as riociguat.
- Patients with severe hepatic impairment, hypotension (BP <90/50 mmHg), or recent stroke or myocardial infarction.
Possible side effect
Common side effects may include headache, flushing, dyspepsia, nasal congestion, dizziness, and visual disturbances (such as altered color perception or blurred vision). Less frequently reported effects include photophobia, nausea, rash, and myalgia. Although rare, serious adverse events such as sudden hearing loss, non-arteritic anterior ischemic optic neuropathy (NAION), or cardiovascular events have been reported. Seek medical attention if you experience an erection lasting more than 4 hours, sudden vision loss, or symptoms of a heart attack.
Drug interaction
- Absolute contraindication: Nitrates (e.g., nitroglycerin, isosorbide) – may cause severe hypotension.
- Potent CYP3A4 inhibitors: Such as ketoconazole, itraconazole, ritonavir, or erythromycin – may increase sildenafil levels; dose adjustment necessary.
- Alpha-blockers: (e.g., doxazosin, tamsulosin) – may potentiate hypotensive effects; caution advised.
- Other antihypertensives: Additive blood pressure-lowering effects possible.
- GC stimulators: e.g., riociguat – contraindicated due to risk of hypotension.
Missed dose
Viagra 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 sufficient time remains before sexual activity (allowing for the drug’s onset and duration). Do not take a double dose to make up for a missed one.
Overdose
In cases of overdose, standard supportive measures should be employed. Expected effects would be an extension of the drug’s vasodilatory properties, including severe hypotension, syncope, and potentially prolonged erection. Renal dialysis is not expected to significantly accelerate clearance due to high protein binding and extensive tissue distribution. Medical attention should be sought immediately for symptomatic management.
Storage
Store at room temperature (20–25°C or 68–77°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.
