1. What OraVerse is and what it is used for OraVerse contains the active substance phentolamine mesilate.
OraVerse is used to reverse the numbness in the lip and tongue caused by the injection of a local anaesthetic associated with a vasoconstrictor (of catecholamine type) given for a routine dental procedure such as teeth cleaning, scaling and planning, cavity filling, crowns.
OraVerse increases blood flow in the blood vessels at the injection site. This accelerates the return of normal sensation in the lip and tongue enabling you to speak, drink liquids and avoid drooling.
OraVerse is for use in adults and in children 6 years of age and older and weighing at least 15 kg
