Understanding Viagra and its Uses

Viagra, or sildenafil, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, enabling a firmer erection suitable for sexual activity.

Dosage varies depending on individual needs and response, typically ranging from 25mg to 100mg. Always follow your doctor’s instructions carefully. Start with the lowest dose, and adjust as needed under medical supervision.

Viagra’s effects generally last for four to five hours. The medication’s onset varies, usually between 30 minutes and one hour after ingestion. Factors like food intake and individual metabolism influence this timing.

Beyond ED, Viagra can also treat pulmonary arterial hypertension (PAH), a condition involving high blood pressure in the arteries leading to the lungs. It improves blood flow in the pulmonary arteries, easing breathing difficulties. This use is prescribed separately and requires specific medical evaluation.

While generally safe, Viagra carries potential side effects. Common ones include headache, facial flushing, and nasal congestion. Rarely, more serious side effects can occur. Consult your doctor immediately if you experience vision changes, prolonged erection (priapism), or chest pain.

Before taking Viagra, disclose all existing medical conditions, particularly heart problems, liver or kidney disease, and previous stroke. Interaction with other medications is also a key consideration; inform your doctor about all your current prescriptions and over-the-counter medications.

Viagra is a prescription medication. Obtain it only from a licensed healthcare provider. Do not purchase from unverified online sources to avoid counterfeit drugs.
