Filitra, a medication containing vardenafil, is commonly prescribed for the treatment of erectile dysfunction. Like other PDE5 inhibitors, it works by increasing blood flow to the penis, but it can also have effects on the cardiovascular system. For most healthy men, Filitra is generally safe when taken in the recommended dose. However, in people with existing heart problems, such as angina, recent heart attack, irregular heartbeat, or uncontrolled blood pressure, it may pose risks. The drug can lower blood pressure, interact dangerously with nitrates, and in rare cases, cause chest pain, palpitations, or dizziness. Anyone with a heart condition should consult their doctor before using Filitra to ensure it is safe for them.
