Sildenafil is primarily used to treat erectile dysfunction and pulmonary arterial hypertension. The medication works by improving blood flow through relaxing blood vessels and reducing pressure in the pulmonary arteries. Your doctor may also prescribe sildenafil for other circulation-related conditions based on your specific medical needs.

Common side effects of sildenafil include headache, flushing, upset stomach, and nasal congestion. Some patients may also experience dizziness, back pain, or changes in vision. Most side effects are mild and temporary, but you should contact your healthcare provider if symptoms persist or worsen.

The typical dosage of sildenafil varies depending on the condition being treated and individual patient factors. For erectile dysfunction, doses usually range from 25mg to 100mg taken as needed, while pulmonary arterial hypertension typically requires 20mg three times daily. Your physician will determine the appropriate dosage based on your medical history and response to treatment.

Alcohol can increase the risk of side effects when taken with sildenafil, particularly dizziness and low blood pressure. It's recommended to limit alcohol consumption while using this medication to avoid potentially dangerous interactions. Your healthcare provider can give you specific guidance about alcohol use based on your individual circumstances.

Sildenafil typically begins working within 30 to 60 minutes after taking the medication. The effects can last for up to 4 hours, though this varies between individuals based on factors like age, health status, and dosage. For best results, it's usually recommended to take sildenafil on an empty stomach.

Yes, sildenafil requires a prescription from a licensed physician in the United States. This medication needs medical supervision due to potential interactions with other drugs and underlying health conditions. Through Doctronic, our licensed doctors can evaluate your health and provide a prescription if medically appropriate.

If you miss a dose of sildenafil for pulmonary arterial hypertension, take it as soon as you remember unless it's almost time for your next dose. For erectile dysfunction, sildenafil is typically taken as needed, so missing a dose is not usually a concern. Never take a double dose to make up for a missed one, as this can increase the risk of side effects.

Store sildenafil at room temperature between 68°F and 77°F (20°C to 25°C) in a dry place away from moisture and heat. Keep the medication in its original container and away from children and pets. Do not store sildenafil in the bathroom or kitchen where humidity and temperature changes can affect the medication's effectiveness.
