Tadasoft 20 mg is usually taken 30–60 minutes before sexual activity. Its effects can last up to 36 hours, giving men a long window for intimacy. It can be taken with or without food, although high-fat meals may slightly delay its onset. The 20 mg dose is generally prescribed for men who need stronger support than the lower 10 mg dose. Tadalafil works by relaxing smooth muscles in the blood vessels of the penis, allowing increased blood flow during sexual arousal. Sexual stimulation is required for it to be effective.
