Taking too much Vilitra 40mg, which contains the active ingredient Vardenafil, can lead to serious side effects. Vardenafil is used to treat erectile dysfunction by increasing blood flow to the penis, but an overdose can cause severe complications. Symptoms of an overdose include a prolonged erection (priapism), which can last for more than 4 hours and cause permanent damage if not treated promptly. Other side effects may include dizziness, lightheadedness, chest pain, rapid heartbeat, or vision disturbances. In extreme cases, an overdose can lead to heart problems or even a heart attack. It’s essential to seek immediate medical help if an overdose is suspected. Always follow prescribed dosages and consult a healthcare provider before adjusting any medication.
