The primary indication for Vidalista pills in males is erectile dysfunction. If you have mild, moderate, or even severe erectile dysfunction, you can use this drug. Vidalista, however, is a prescription medication that needs to be used under a doctor's supervision exclusively. Typically, Vidalista 40 mg is taken orally half an hour before engaging in sexual activity. It is crucial to remember that taking it infrequently may cause it to take longer to start working. It can also be used as needed. Vidalista's effects can linger for up to 36 hours.
