Viagra, known scientifically as Sildenafil, is a well-known oral medication produced by Dragon Pharma. It is widely recognized for its effectiveness in treating erectile dysfunction (ED) in men. This detailed guide will explore various aspects of Viagra, including its indications, contraindications, administration, medical action, precautions, side effects, overdosage, and conclusion.
Indication
Viagra is primarily indicated for:
- Erectile Dysfunction (ED): Viagra is prescribed to men who have difficulty achieving or maintaining an erection sufficient for sexual intercourse. It helps improve blood flow to the penis, enabling a firm and sustained erection when sexually aroused.
- Pulmonary Arterial Hypertension (PAH): In addition to treating ED, Sildenafil is also used to treat PAH, a condition characterized by high blood pressure in the arteries of the lungs. It helps relax the blood vessels, reducing the workload on the heart and improving exercise capacity.
Viagra’s primary role is to enhance sexual function and treat specific cardiovascular conditions, making it a valuable medication for many men.
Contra-indications
Viagra is contraindicated in the following situations:
- Nitrate Medications: Men taking nitrates for chest pain or heart problems should not use Viagra, as the combination can cause a severe drop in blood pressure.
- Severe Cardiovascular Conditions: Those with severe heart or liver problems should avoid Viagra. It can exacerbate these conditions and lead to serious complications.
- Allergic Reactions: Individuals who have had allergic reactions to Sildenafil or any other ingredients in Viagra should not use this medication.
- Retinitis Pigmentosa: Patients with this rare inherited eye condition should avoid Viagra, as it can potentially worsen vision problems.
Consulting with a healthcare provider before starting Viagra is crucial to ensure it is safe based on individual health conditions and medical history.
Administration
Viagra is administered orally in tablet form. The dosage and timing can vary depending on the individual’s needs and response to the medication.
- Standard Dosage: The typical starting dose for treating ED is 50 mg taken approximately one hour before sexual activity. Depending on efficacy and tolerability, the dose can be adjusted to 25 mg or increased to a maximum of 100 mg.
- Frequency: Viagra should not be taken more than once a day. It is important to follow the prescribed dosage and not exceed the recommended frequency to avoid adverse effects.
- Timing: For best results, take Viagra on an empty stomach. The onset of action may be delayed if taken with a high-fat meal.
- For PAH: The dosage for PAH is usually different and should be strictly followed according to a healthcare provider’s prescription.
Following the recommended dosage and administration guidelines is essential to maximize the benefits and minimize the risks associated with Viagra.
Medical Action
Sildenafil, the active ingredient in Viagra, belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Its medical action includes:
- Enhanced Blood Flow: Viagra works by inhibiting the PDE5 enzyme, which results in the relaxation of smooth muscles and increased blood flow to the penis. This helps achieve and maintain an erection when sexually stimulated.
- Improved Exercise Capacity: For PAH patients, Viagra relaxes the blood vessels in the lungs, reducing pulmonary blood pressure and improving the ability to exercise.
- Onset and Duration: Viagra typically starts working within 30 to 60 minutes after ingestion, with effects lasting up to four hours. However, this can vary based on individual factors and the presence of food in the stomach.
These actions make Viagra effective for improving erectile function and managing specific cardiovascular conditions.
Precautions
Using Viagra requires certain precautions to ensure safety and effectiveness:
- Health Monitoring: Men with underlying health conditions such as heart disease, high blood pressure, or diabetes should be closely monitored while using Viagra.
- Avoiding Nitrates: As mentioned earlier, combining Viagra with nitrate medications can cause a dangerous drop in blood pressure. Inform your healthcare provider about all medications you are taking.
- Alcohol Consumption: Limit alcohol intake while using Viagra, as excessive drinking can impair its effectiveness and increase the risk of side effects.
- Potential Interactions: Inform your healthcare provider about any other medications, supplements, or herbal products you are taking to avoid potential interactions.
- Vision Changes: If you experience sudden vision loss or changes, stop taking Viagra and seek medical attention immediately.
Adhering to these precautions helps minimize risks and ensures the safe use of Viagra.

- Indigestion: Some individuals may have stomach discomfort or indigestion.
- Nasal Congestion: Stuffy or runny nose can occur in some cases.
- Vision Changes: Temporary changes in vision, such as blue tint, blurred vision, or sensitivity to light, may occur.
Less common but more serious side effects include:

Overdosage
An overdose of Viagra can lead to severe health complications. Symptoms of overdose may include:
