Tadalista 10 is a prescription medicine intended to treat erectile dysfunction. Tadalafil, the key active ingredient, aids in the maintenance of an erection by dilating blood vessels and increasing blood flow to the penis. It creates an erection by relaxing the muscles in the penis’ blood vessels, hence increasing blood flow. It is effective for up to 36 hours and is often given 30-60 minutes before sexual activity. The most common side effects of this medicine include flushing, headaches, lightheadedness, blurred vision, tense muscles, upset stomach, and rashes. Avoid drinking while taking this medication since it increases the risk of undesirable side effects.
