Tadalista 20 mg is commonly prescribed as a standard effective dose for many men who need stronger support than lower doses such as 5 mg or 10 mg. A doctor may recommend it based on the severity of ED, overall health, and response to previous treatments. The medicine works by relaxing smooth muscles in blood vessel walls, improving circulation to the penile tissues during sexual arousal. It does not cause an erection automatically; sexual stimulation is required for it to be effective. https://www.genericday.com/tadalista-20-mg.html
