A drug called Vilitra 20 is prescribed to males to treat erectile dysfunction (ED). Vardenafil, the key ingredient, improves blood flow to the penis, leading to longer-lasting erections and better sexual performance. As long as you swallow the tablet whole, you can take it with or without meals. Avoid chewing, crushing, or breaking it as you take it for the entire recommended amount of time. It usually takes 60 minutes after oral ingestion to start working. Consult your physician for detailed use instructions.
