The active ingredient of Vidalista pills, a medication used to treat erectile dysfunction, is tadalafil. This medicine enhances blood flow to the penis during sexual stimulation, leading to an erection. Nevertheless, utilizing it could have several side effects, ranging from small to severe. Common moderate side effects include flushing, indigestion, headache, back pain, and muscle aches. Tadalafil should be taken at least 30 to 60 minutes before sexual activity and no more than once per 24 hours, while it can occasionally be taken as needed. See your physician to find out when it's best to take tadalafil before having sex. Take tadalafil exactly as prescribed. Never take it in excess or insufficiently, or more often than prescribed by your physician.
