Tadalista 10 is considered an excellent drug for erectile dysfunction (impotence). Tadalafil is a very effective medicine to cure impotence. It also facilitates blood flow to the male genitalia. This gives men a long-lasting reflex during sex and allows them to enjoy sex. Take this pill 30-40 minutes before intercourse. But if you are currently suffering from any major illness, consult your doctor before taking the pill. You should take a single pill within 24 hours as you may experience side effects if you overdose.
