Vilitra 40, a medication used to treat erectile dysfunction, contains vardenafil, which can affect blood flow and interact with cardiovascular health. People with certain heart conditions should avoid using Vilitra 40mg, especially those with severe heart disease, heart failure, or unstable angina. It can also be risky for individuals with low blood pressure (hypotension), as vardenafil may further lower blood pressure, potentially leading to dizziness or fainting. Additionally, those who have recently had a heart attack or stroke, or those with irregular heart rhythms, should avoid the drug. Always consult a healthcare provider before starting this medication, especially if you have a history of heart conditions.
