Dentistry Today


Approved by the US Food and Drug Administration, the Kovanaze (tetracaine HCl and oxymetazoline HCl) Nasal Spray from St. Renatus is the first product that allows dental anesthesia to be delivered through a nasal spray without using a needle.

It is intended for use in dentistry as a topical anesthetic delivered in the nasal cavity to achieve regional anesthesia for the restorative treatment of teeth. Like traditional dental injections, it delivers local dental anesthetic, but without the needle.

Kovanaze is indicated for regional anesthesia when performing a restorative procedure on tooth Nos. 4 through 13 and A through J in adults and children who weigh 40 kg or more.
