Tadalafil, a drug mostly used to treat male erectile dysfunction (ED), is marketed under the name Tadarise.  It facilitates an erection by blocking the phosphodiesterase type 5 (PDE5) enzyme, which increases blood flow to the penis during sexual stimulation.  Because Tadarise comes in a range of strengths—2.5 mg, 5 mg, 10 mg, 20 mg, 40 mg, and 60 mg—dosing can be customised to meet individual needs and tolerance.

Usually, the drug is taken with or without food 30 to 60 minutes prior to having intercourse.  Because of its 36-hour half-life, it's known as "the weekend pill."  Headache, dizziness, face flushing, nasal congestion, and indigestion are typical adverse effects.  Although they are uncommon, serious side effects include chest pain, priapism (long-lasting erection), and visual abnormalities.  Tadarise shouldn't be taken by people who have serious liver or heart issues, or by those who are taking nitrates.  To guarantee safety and effectiveness, always speak with a healthcare professional before beginning treatment.
