Vidalista tadalafil is an oral solution used to treat erectile dysfunction and pulmonary arterial hypertension. Vidalista tadalafil is designed to boost sexual excitement during a severe, prolonged erection while also relaxing smooth muscles, which promotes blood flow to certain regions of the penis. As directed by your doctor, take it orally for 30 to 60 minutes before making love. Always consult with a doctor before taking any medication. It is safe to take as prescribed by a physician. Some moderate side effects include dizziness, headaches, flushing, upset stomach, stuffy nose, and diarrhea. Taking Vidalista tadalafil with a high-fat meal may lead to decreased medicine absorption.
