Phosphodiesterase inhibitors, such as the Vidalista pills, are prescribed to treat erectile dysfunction, premature ejaculation, and impotence. Tadalafil works by blocking the activity of phosphodiesterase type 5 in the body. Flushing, nosebleeds, indigestion, headaches, nausea, vomiting, and dry mouth are common side effects of this medicine. When using this medication, limit your alcohol intake. After a substantial, high-fat meal, the effects of Vidalista tablets could take longer to become apparent. Eat a small meal if needed before taking the medication. Alcohol consumption excess can reduce its effectiveness.
