What is Viagra?
Viagra, known generically as sildenafil, is a well-known medication used to treat erectile dysfunction (ED), a common condition where a man has difficulty achieving or maintaining an erection suitable for sexual intercourse. Developed by Pfizer Pharmaceuticals, Viagra has helped millions of men regain confidence and improve their quality of life since it was first introduced to the market in 1998.
How Viagra Works
Viagra belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. When a man is sexually stimulated, the body releases nitric oxide into the penis, which activates an enzyme that produces cyclic guanosine monophosphate (cGMP). This chemical relaxes smooth muscle cells, increasing blood flow to the penis, and thereby causing an erection. Viagra works by blocking PDE5, an enzyme that breaks down cGMP, allowing cGMP to accumulate and persist longer, enhancing the natural erection process.
Indications for Use
Viagra is primarily prescribed for the treatment of erectile dysfunction in men. It is important to note that Viagra does not cure ED or increase sexual desire; it merely facilitates an erection in response to sexual stimulation. Viagra is also sometimes used to treat pulmonary arterial hypertension (high blood pressure in the lungs).
Recommended Dosages and Usage
The typical starting dose of Viagra for most men is 50 mg, taken as needed approximately one hour before sexual activity. Depending on effectiveness and tolerance, the dosage may be increased to a maximum of 100 mg or decreased to 25 mg. It is crucial to follow a doctor’s instructions and not exceed the prescribed dose or frequency, as this could increase the risk of side effects.
- Start with 50 mg as needed, about one hour before sexual activity.
- Adjust dosage based on efficacy and tolerance, with a maximum of 100 mg.
- Avoid taking more than one dose in a 24-hour period.
- Take on an empty stomach for quicker absorption.
Possible Side Effects
While Viagra is generally well-tolerated, some men may experience side effects. Common side effects include headaches, flushing, indigestion, nasal congestion, dizziness, and visual changes. Rare but serious side effects may include sudden vision loss or an erection lasting more than four hours (priapism), which requires immediate medical attention.
Expert Opinions
Dr. Emily Harper, a renowned urologist, states, “Viagra has revolutionized the treatment of erectile dysfunction. It’s important to consult with a healthcare provider to determine the correct dosage and ensure it’s safe based on individual health conditions.”

Viagra Alternatives and Comparisons
There are other PDE5 inhibitors available, such as Cialis (tadalafil) and Levitra (vardenafil), which offer similar effects with different durations and onset times. Some may prefer these alternatives based on their lifestyle and frequency of sexual activity.
Precautions and Interactions
Before taking Viagra, inform your healthcare provider about any medical conditions, particularly heart problems, recent strokes or heart attacks, liver or kidney disease, and any allergies. Viagra may interact with certain medications, including nitrates (often prescribed for chest pain), and could lead to dangerous drops in blood pressure.
