Introduction
Viagra 100 mg contains sildenafil citrate, a well-known PDE5 inhibitor used for the management of erectile dysfunction. It may help men achieve and maintain an erection suitable for sexual activity when sexual stimulation is present. Because its effects depend on blood-flow changes and individual health factors, a clinician’s assessment is important before starting treatment. Understanding how the medicine works, how to use it safely and when to seek medical advice may support effective and confident use.
How Does Viagra Work?
Viagra enhances the action of nitric oxide released during sexual stimulation. This process increases cyclic GMP, allowing smooth muscle relaxation and improved blood flow to the corpora cavernosa, which supports erectile function. The onset of effect may occur within 30 to 60 minutes for many men and aligns with sildenafil’s known vasodilatory properties. These mechanisms explain why timing and adequate stimulation are essential for the medicine to work well.
Dosage and Practical Use
A clear understanding of dose and timing may help ensure both safety and effectiveness.
- Typical dose: Viagra 100 mg is the highest commonly prescribed single dose, while many men begin at 50 mg and adjust based on response
- Timing: Take one dose 30 to 60 minutes before sexual activity, with effects that may last up to 4–5 hours for some individuals
- Frequency: Do not take more than one dose in 24 hours, and always follow your prescriber’s instructions. Discuss any side effects or the need for dose changes with your clinician
Common Side Effects and Interactions
Several common reactions may occur, but many are mild and temporary.
- Headache, flushing, nasal congestion, dyspepsia and visual changes
- Do not combine sildenafil with nitrates used for angina, as this may cause dangerous drops in blood pressure
- Individuals with significant heart disease, unstable angina or a recent stroke or heart attack should consult a cardiologist before use
When to Consult a Doctor?
Recognising warning signs early may help prevent complications.
- Persistent erection lasting more than four hours, which requires immediate emergency care
- Sudden vision loss or hearing changes, which need urgent medical review
- Erectile dysfunction that appears suddenly, is painful or occurs with other symptoms, as this may indicate underlying conditions such as cardiovascular disease or diabetes
