Viagra (sildenafil citrate) is a prescription medication clinically proven to treat erectile dysfunction (ED) in adult men. As a phosphodiesterase type 5 (PDE5) inhibitor, it works by increasing blood flow to the penis, facilitating an erection sufficient for sexual activity when combined with sexual stimulation. This oral tablet has been a trusted first-line therapy since its approval, offering a reliable solution for men seeking to regain sexual function and improve intimate relationships. It is not an aphrodisiac and does not protect against sexually transmitted diseases.
Features
- Active ingredient: Sildenafil citrate
- Available dosages: 25 mg, 50 mg, and 100 mg film-coated tablets
- Onset of action: Typically within 30–60 minutes after ingestion
- Duration of effect: Efficacy can last up to 4–5 hours
- Administration: Oral, with or without food (though high-fat meals may delay absorption)
- Manufacturer: Pfizer Inc., developed and produced under stringent quality controls
Benefits
- Achieves and sustains firmer erections suitable for satisfactory sexual intercourse
- Improves overall sexual confidence and reduces anxiety related to performance
- Enhances intimacy and relationship satisfaction for both partners
- Offers predictable and rapid onset when used as directed
- Supported by decades of clinical research and real-world use
- Provides a discrete and convenient oral treatment option
Common use
Viagra is indicated for the treatment of erectile dysfunction, the consistent or recurrent inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual performance. It is used by adult men experiencing ED due to various physiological or psychological causes, including but not limited to diabetes, hypertension, cardiovascular disease, prostate surgery, depression, or stress. It is intended for use prior to anticipated sexual activity and is not meant for continuous daily dosing unless specifically advised by a physician for off-label use cases (e.g., pulmonary arterial hypertension, under a different brand name and dosing regimen).
Dosage and direction
The recommended starting dose for most patients is 50 mg taken 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 certain populations:
- For patients aged 65 and older, or those with hepatic impairment or severe renal impairment (creatinine clearance <30 mL/min), a starting dose of 25 mg is recommended.
- The dosing frequency should not exceed once per day.
- Tablets should be swallowed whole with a glass of water; breaking, crushing, or chewing is not advised.
Precautions
- Prior to use, a thorough medical evaluation should be conducted to diagnose ED and identify underlying causes.
- Cardiovascular status should be assessed, as sexual activity carries potential cardiac risk. Viagra is not recommended for men for whom sexual activity is inadvisable due to cardiovascular status.
- Use with caution in patients with anatomical deformation of the penis (e.g., Peyronie’s disease, angulation) or conditions predisposing to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia).
- Avoid consumption of grapefruit or grapefruit juice, which may increase sildenafil concentrations.
- Not intended for use by women or children.
Contraindications
Viagra is contraindicated in:
- Patients taking any form of organic nitrates or nitric oxide donors (e.g., nitroglycerin, isosorbide mononitrate or dinitrate), due to the risk of severe hypotension.
- Individuals with a known hypersensitivity to sildenafil or any component of the tablet.
- Patients with severe hepatic impairment.
- Those with hypotension (resting systolic BP <90 mmHg) or recent history of stroke or myocardial infarction.
- Men with hereditary degenerative retinal disorders, including retinitis pigmentosa.
Possible side effects
Common side effects (usually mild to moderate and transient) include:
- Headache
- Flushing
- Dyspepsia
- Nasal congestion
- Dizziness
- Visual disturbances (e.g., altered color vision, blurred vision, increased light sensitivity)
Less common but serious side effects requiring immediate medical attention:
- Priapism (prolonged erection lasting more than 4 hours)
- Sudden hearing loss or tinnitus
- Sudden vision loss in one or both eyes
- Cardiovascular events (e.g., angina, arrhythmia)
- Allergic reactions (rash, itching, swelling)
Drug interaction
Viagra may interact with:
- Nitrates: Concomitant use can cause life-threatening hypotension.
- Alpha-blockers (e.g., doxazosin, tamsulosin): Additive blood pressure-lowering effects; co-administration is not recommended.
- CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin): May increase sildenafil levels; dose adjustment is necessary.
- CYP3A4 inducers (e.g., rifampin): May decrease sildenafil levels.
- Antihypertensives: Potential additive hypotensive effects.
- Other PDE5 inhibitors: Concurrent use is not recommended.
Missed dose
Viagra is taken on an as-needed basis prior to sexual activity. There is no scheduled dosing regimen, so a “missed dose” does not apply. Do not take more than one dose within a 24-hour period.
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. Medical supervision is required; manage hypotension with fluid administration and/or alpha-adrenergic agonists (e.g., phenylephrine) as needed. Dialysis is not expected to significantly enhance elimination due to high protein binding and extensive tissue distribution.
Storage
Store at room temperature (15–30°C or 59–86°F). Keep in the original container, tightly closed, and 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 being diagnosed with ED following prostate surgery, my urologist prescribed Viagra. The 50 mg dose has consistently allowed me to achieve erections sufficient for intercourse. Side effects were minimal—some mild flushing initially—but well worth the benefit.” — John D., 58
“I’ve tried other ED medications, but Viagra works most predictably for me. I take it about an hour before, and the effect lasts long enough for relaxed intimacy. It has greatly reduced the performance anxiety I was experiencing.” — Michael T., 52
“As a cardiologist, I carefully evaluate my patients before prescribing. For appropriately selected men without contraindications, Viagra remains a reliable and effective option. Patient education on proper use and potential interactions is key.” — Dr. Evans, MD
