Vidalista 20 mg is a PDE5 inhibitor. Your penis’ blood arteries relax as a result of its function. When sexually stimulated, this allows blood to enter the penis and cause an erection. If you do not have erectile dysfunction, do not take this medicine. It should be taken no more than once per day. According to Vidalista 20 mg, it takes 30-60 minutes to start working and can stay in your system for up to 36 hours. If you must eat, attempt to follow a light, low-fat diet. A heavy, greasy lunch will diminish the medication’s effectiveness. The medicine can be taken with or without food.
