Tadalafil, including Tadalista 40, typically starts working within 30 minutes to 1 hour after ingestion. The onset of action may vary among individuals and can be influenced by factors such as sexual stimulation and food intake. The effects of tadalafil can last for up to 36 hours after taking Tadalista 40. This extended duration of action is a characteristic feature of tadalafil and allows for flexibility in timing sexual activity within that timeframe.
