Formulated with sildenafil citrate as the active pharmaceutical ingredient, these capsules function as a phosphodiesterase type 5 (PDE5) inhibitor, facilitating improved blood flow to the penile tissues. This medication is intended for use under medical supervision and requires a prescription, ensuring appropriate patient selection and dosing. The following sections provide a comprehensive overview of its features, benefits, and essential safety information.

Common use
Viagra Capsules are primarily indicated for the treatment of erectile dysfunction in adult males. Erectile dysfunction is characterized by the consistent inability to attain or sustain an erection adequate for satisfactory sexual performance. The medication is used on an as-needed basis, approximately 30–60 minutes prior to anticipated sexual activity. It is important to note that sexual stimulation is required for the drug to produce its intended effect. Viagra does not increase libido nor offer protection against sexually transmitted infections.
Dosage and direction
The recommended starting dose for most patients is 50 mg taken orally once daily, approximately one hour before sexual activity. Based on efficacy and tolerability, the dose may be increased to a maximum of 100 mg or decreased to 25 mg. Dosage adjustment is necessary in patients aged over 65, those with hepatic impairment, severe renal impairment (creatinine clearance <30 mL/min), or concurrently taking certain CYP3A4 inhibitors such as erythromycin or saquinavir. The capsule should be swallowed whole with a glass of water; it may be taken with or without food, although high-fat meals may delay absorption.
Precautions
Patients should undergo a thorough medical evaluation to diagnose erectile dysfunction, identify potential underlying causes (e.g., cardiovascular disease, diabetes, hormonal imbalances), and assess cardiovascular suitability for sexual activity. Use with caution in patients with anatomical deformation of the penis, predisposition to priapism, bleeding disorders, or active peptic ulceration. Avoid consumption of grapefruit or grapefruit juice, which may increase sildenafil concentrations. Vision changes, including non-arteritic anterior ischemic optic neuropathy (NAION), have been reported—discontinue use if sudden vision loss occurs.
Contraindications
Viagra Capsules are contraindicated in patients with a known hypersensitivity to sildenafil or any excipient. Concomitant use with organic nitrates or nitric oxide donors in any form is strictly prohibited due to the risk of profound hypotension. The medication is also contraindicated in patients using guanylate cyclase stimulators such as riociguat. Men for whom sexual activity is inadvisable due to underlying cardiovascular conditions should not use this product.
Possible side effects
Common adverse reactions include headache, flushing, dyspepsia, nasal congestion, and dizziness. Less frequently reported effects include visual disturbances (e.g., altered color perception, blurred vision), back pain, myalgia, and nausea. Serious side effects may include priapism, sudden hearing loss, severe hypotension, myocardial infarction, or stroke. Patients should seek immediate medical attention if an erection persists longer than 4 hours.
Drug interaction
Sildenafil is primarily metabolized by CYP3A4 and to a lesser extent by CYP2C9. Concomitant use with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir) may significantly increase sildenafil exposure—dose reduction is advised. Alpha-blockers may potentiate hypotensive effects; therefore, simultaneous administration should be avoided. Interactions are also possible with other antihypertensives, protease inhibitors, and erythromycin.
Missed dose
As Viagra Capsules are used on an as-needed basis, the concept of a “missed dose” does not apply. Patients should take one capsule approximately one hour before anticipated sexual activity. Do not take more than one dose in a 24-hour period.
Overdose
In cases of overdose, standard supportive measures should be employed. Expected effects may mirror those of side effects but more severe, including significant hypotension, syncope, and prolonged erection. Priapism requires urgent medical intervention to avoid long-term complications. Hemodialysis is not expected to accelerate clearance due to high protein binding and extensive tissue distribution.
Storage
Store at room temperature (15–30°C) in a dry place, protected from light and moisture. Keep the blister pack intact until immediately before use. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
