Vidalista 5 mg (tadalafil 5 mg) does not work instantly. It usually needs time to be absorbed and does not create an erection automatically. On-demand effect: Tadalafil may start working in about 30–60 minutes after taking it, but some people need longer. Duration: Its effects can last up to about 36 hours, though this does not mean you will have an erection for that long. Daily use: Vidalista 5 mg is often used as a once-daily dose for some men with ED. With daily use, tadalafil levels build up over several days, and improvement may become more consistent after regular use. Remember: ***** stimulation is still required. A heavy meal, especially a large fatty meal, may delay the onset for some people. Avoid taking extra doses if it seems slow to work. If Vidalista 5 mg is not giving enough effect, tell me whether you take it daily or only before sex, your age, and how long you have been using it. I can help you understand whether the timing or dose may be the issue.
