What are the consequences of taking too much Viagra?

Viagra, clinically known as sildenafil citrate tablets, has side effects such as headaches, facial flushing, gastrointestinal discomfort, and vision abnormalities, which are more likely to be triggered by taking too much Viagra. Also, erections can last longer than four hours. If left untreated, abnormal erections can cause permanent damage to the penis. Viagra can cause myocardial infarction, arrhythmia, cerebral thrombosis and other cardiovascular and cerebrovascular diseases. Therefore, patients with old age, weakness and heart disease should be used with caution.
