Vidalista 5 typically starts working within 30 minutes to 1 hour after ingestion, with its peak effectiveness occurring within 2 hours. Its rapid onset of action allows for relatively quick onset of erectile response after taking the medication. It's important to note that Vidalista 5, like other medications containing Tadalafil, requires sexual stimulation to be effective. It does not cause spontaneous erections and will not work without sexual arousal.
