Filitra 10, which contains the active ingredient Vardenafil, is used to treat erectile dysfunction. While it is generally safe when taken as prescribed, there are certain situations in which you should seek immediate medical attention after using it. If you experience symptoms like swelling of the face, lips, tongue, or throat, or difficulty breathing, it could indicate a serious allergic reaction requiring urgent medical care. If you experience chest pain, irregular heartbeat, or other symptoms of a heart attack, such as nausea or sweating, you should seek emergency medical help immediately.

If you have an erection lasting more than 4 hours, it can cause permanent damage to the penis. Seek medical help immediately if this occurs. These symptoms may indicate a dangerous drop in blood pressure, especially if you have underlying heart conditions or are taking other medications for blood pressure.
