Vidalista 20 is known for its long duration of action, which can last up to 36 hours. This extended window of effectiveness has earned it the nickname "The Weekend pill." However, the exact duration can vary from person to person, and it's important to note that sexual stimulation is still necessary to achieve an erection while the medication is active. For personalized information and guidance on its use, it's advisable to consult with a healthcare provider or pharmacist.
