Tadalista Professional is a prescription medication that needs to be used under a doctor's supervision. Don't give the medication to anyone else because it might not be able to address the condition they have. Never share your medications with others, keep all medications out of the reach of children and pets, and take this one time only as directed by a prescription. Before beginning to use tadalafil and each time you receive a refill, read the Patient Information Leaflet, if it is available from your pharmacist. See your physician or pharmacist if you have any queries. Take this drug orally, as prescribed by your physician, either with or without food. Tadalafil should not be taken more than once per day.
