Sildenafil Citrate Tablet

What is Sildenafil Citrate?

Sildenafil Citrate is the generic name for Viagra. It's primarily used to treat erectile dysfunction (ED), also known as male impotence. The medication works by increasing blood flow to the penis, helping to achieve and maintain an erection. Importantly, it's also FDA-approved for treating pulmonary arterial hypertension (PAH), a condition affecting blood vessels in the lungs.

Important Information for Your Doctor

Before starting Sildenafil Citrate, it's crucial to inform your healthcare provider about your medical history. This includes disclosing any of the following:

• Eye problems: This includes any vision issues, especially retinitis pigmentosa (a rare inherited eye disease).
• Heart conditions: A history of heart disease, angina (chest pain), high or low blood pressure, heart attack, or other heart problems should be reported.
• Kidney or liver disease: Sildenafil Citrate's metabolism can be affected by these conditions.
• Stroke: Prior strokes need to be disclosed to your doctor.
• Allergies: Any allergies to sildenafil, other medications, foods, dyes, or preservatives should be mentioned.

How to Take Sildenafil Citrate

Sildenafil Citrate is taken orally with a glass of water. The typical dose is taken approximately one hour before anticipated sexual activity. It's generally recommended to take no more than one dose per day. Strictly follow your doctor's instructions regarding dosage and frequency. In case of a suspected overdose, immediately contact a poison control center or emergency room.
