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 cornerstone of ED treatment since its approval, offering a reliable and well-studied option for men seeking to improve their sexual health and intimate relationships. It is not an aphrodisiac and does not protect against sexually transmitted diseases.
Features
- Active Pharmaceutical Ingredient: Sildenafil citrate.
- Available Dosage Strengths: 25 mg, 50 mg, and 100 mg oral tablets.
- Mechanism of Action: Selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).
- Onset of Action: Typically within 30 to 60 minutes after ingestion.
- Duration of Effect: The therapeutic window for achieving an erection can last up to 4-5 hours.
- Administration: Oral route, with or without food (though high-fat meals may delay absorption).
- Brand and Generic Status: Available under the brand name Viagra and various generic equivalents.
Benefits
- Achieves reliable erections sufficient for satisfactory sexual intercourse when sexually aroused.
- Improves overall sexual satisfaction and confidence for both the individual and their partner.
- Offers a predictable and rapid onset of action, allowing for spontaneity in sexual activity.
- Provides a well-established safety and efficacy profile backed by decades of clinical use and research.
- Enhances quality of life by addressing a significant aspect of men’s health and intimate relationships.
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 on an as-needed basis prior to anticipated sexual activity. Its use is applicable for ED of various etiologies, including vasculogenic, neurogenic, and psychogenic origins, as well as cases of mixed causality. It is not intended 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 sexual activity. Based on efficacy and tolerability, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. Dosing should be limited to a maximum of once per 24-hour period. The tablet should be swallowed whole with a glass of water. Sexual stimulation is required for the medication to be effective. For patients taking certain concomitant medications (e.g., alpha-blockers, potent CYP3A4 inhibitors) or those with significant hepatic impairment, severe renal impairment, or in older age, a starting dose of 25 mg is recommended. Consult a physician for personalized dosage instructions.
Precautions
- Prior to use, a thorough medical evaluation should be conducted to diagnose erectile dysfunction, determine potential underlying causes, and identify appropriate treatment options.
- Use with caution in patients with anatomical deformation of the penis (e.g., angulation, cavernosal fibrosis, or Peyronie’s disease), or conditions that may predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia).
- Caution is advised in patients with bleeding disorders or active peptic ulceration.
- Cardiovascular status should be assessed, as sexual activity carries a potential cardiac risk. Viagra is not recommended for men for whom sexual activity is inadvisable due to their cardiovascular status.
- Use is not recommended with other treatments for erectile dysfunction.
- Protect tablets from light and moisture.
Contraindications
- Hypersensitivity to sildenafil or any other component of the tablet.
- Concurrent administration of any form of organic nitrates (e.g., nitroglycerin, isosorbide mononitrate or dinitrate) or nitric oxide donors (e.g., amyl nitrite “poppers”) in any form, either regularly or intermittently. This combination can cause a sudden, life-threatening drop in blood pressure.
- Concurrent administration with guanylate cyclase stimulators, such as riociguat.
- Use in men for whom sexual activity is not recommended due to underlying cardiovascular status.
Possible side effect
Like all medicines, Viagra can cause side effects, although not everybody gets them. Most are mild to moderate and transient.
Very common (may affect more than 1 in 10 people):
- Headache
- Flushing
Common (may affect up to 1 in 10 people):
- Dyspepsia (indigestion)
- Nasal congestion
- Dizziness
- Visual disturbances (e.g., blurred vision, changes in color vision, increased sensitivity to light)
- Nausea
Uncommon (may affect up to 1 in 100 people):
- Hypersensitivity reactions (including skin rash)
- Back pain, myalgia (muscle pain)
- Priapism (a prolonged and painful erection lasting more than 4 hours; requires immediate medical attention to prevent permanent damage)
Rare cases of sudden decrease or loss of vision or hearing have been reported post-marketing in temporal association with the use of PDE5 inhibitors, including Viagra. It is not possible to determine if these events are related directly to the medicine or to other factors.
Drug interaction
- Nitrates: Concomitant use is contraindicated due to the risk of severe hypotension.
- Alpha-blockers: Concomitant use can lead to symptomatic hypotension in some patients. A starting dose of 25 mg for Viagra is recommended, and the alpha-blocker should be stabilized first.
- Potent CYP3A4 Inhibitors: Drugs like ketoconazole, itraconazole, ritonavir, and clarithromycin can significantly increase sildenafil plasma concentrations. A maximum dose of 25 mg of Viagra within a 48-hour period is recommended.
- Other Antihypertensives: Viagra may add to the blood-pressure-lowering effects of other antihypertensive agents.
- Guanylate Cyclase Stimulators (e.g., Riociguat): Concomitant use is contraindicated due to the risk of hypotension.
Missed dose
Viagra is not intended for scheduled daily dosing; it is taken on an as-needed basis. Therefore, the concept of a “missed dose” does not apply. Simply take one tablet when you plan to be sexually active, ensuring you adhere to the maximum frequency of once per day.
Overdose
In cases of overdose, the expected clinical findings would be an extension of the known adverse effect profile, primarily related to vasodilation. Symptoms could include severe hypotension, syncope, prolonged erection, and potentially serious cardiovascular events. Standard supportive measures should be employed, which may include keeping the patient in the supine position with the legs elevated to help restore blood pressure. As sildenafil is highly protein-bound, it is not expected to be dialyzable. Management of priapism requires immediate urological intervention.
Storage
Store Viagra tablets at room temperature between 20°C to 25°C (68°F to 77°F), with excursions permitted between 15°C and 30°C (59°F and 86°F). Keep the tablets in their original blister pack or bottle to protect them from light and moisture. Keep all medicines out of the sight and reach of children. Do not use medicine after the expiration date printed on the pack.

Reviews
- “As a urologist with over 20 years of experience, I have prescribed sildenafil to thousands of patients. It remains a first-line, highly effective option for the majority of men with erectile dysfunction. Its predictable pharmacokinetics and well-understood side effect profile make it a reliable choice in a tailored treatment plan.” – Dr. Evan R., MD, Urology
- “After a prostatectomy, I was concerned about my sexual health. My cardiologist cleared me, and my urologist started me on 50mg Viagra. The results have been transformative, not just physically but for my overall confidence and relationship with my wife. It works exactly as described when I take it about an hour beforehand.” – Mark T., 58
- “The clinical data for sildenafil is robust. It’s important for patients to understand that it is an enabling agent, not a stimulant. Proper patient education on the need for sexual stimulation and managing expectations is crucial for treatment success and satisfaction.” – Dr. Sarah L., Clinical Pharmacologist
- “I tried the 25mg dose first and experienced some flushing and a slight headache, but it was manageable. My doctor suggested taking it on an empty stomach to improve consistency, and that helped. I’ve since moved to the 50mg dose with great success and minimal side effects.” – James K., 62
- “In our clinic, we emphasize a complete health assessment before prescribing any ED medication. For appropriate candidates without contraindications, Viagra is a cornerstone therapy. We discuss all options, but its long track record is a significant benefit for many patients.” – Nurse Practitioner Amy B., Men’s Health Clinic
