About Kovanaze®

deviceNasal Spray Utilizing Needle-Free Technology

  • Indication: KOVANAZE is indicated for regional anesthesia when performing a restorative procedure on Teeth 4-13 and A-J in adults and children who weigh 40 kg or more.
  • Patients may not experience the same sensations of numbness or tingling of the lips and cheeks associated with injectable anesthetics.
  • Kovanaze provides regional anesthesia with 96% efficacy in teeth #5-12, 64% in #4 and #13*, therefore Kovanaze offers a needle-free alternative to the majority of anterior maxillary injections.

*In a Phase 3, randomized, double-blind study comparing the efficacy and safety of KOVANAZE to placebo for providing dental anesthesia sufficient to complete a dental procedure on a single maxillary tooth (#4-13) in adults, 150 patients received either KOVANAZE (n=100) or placebo (n=50) as a dose of two or three 0.2 mL intranasal sprays. Eighty-eight percent of KOVANAZE patients were able to complete the dental procedure without the need for rescue medication compared to 28% of patients who received placebo. KOVANAZE had a lower success rate (64%) for dental procedures on the 2nd pre-molar (teeth #4 and #13) compared with 96% for more anterior teeth (#5 through #12).

Important Safety Information

IMPORTANT SAFETY INFORMATION: KOVANAZE is indicated for regional anesthesia when performing a restorative procedure on Teeth 4-13 and A-J in adults and children who weigh 40 kg or more. Use in patients with uncontrolled hypertension or inadequately controlled active thyroid disease of any type is not advised. Tetracaine may cause methemoglobinemia, particularly in conjunction with methemoglobin-inducing agents. Use of KOVANAZE in patients with a history of congenital or idiopathic methemoglobinemia is not advised. Methemoglobinemia should be considered if central cyanosis unresponsive to oxygen therapy occurs, especially if methemoglobinemia-inducing agents have been used. Confirm diagnosis by measuring methemoglobin level with co-oximetry. Treat clinically significant symptoms of methemoglobinemia with a standard clinical regimen. Allergic or anaphylactic reactions can occur. If an allergic reaction occurs, seek emergency help immediately. KOVANAZE is contraindicated in patients with a history of allergy to tetracaine, benzyl alcohol, other ester local anesthetics, p-aminobenzoic acid (PABA), oxymetazoline, or any other component of the product. Some clinical trial patients experienced an increase in blood pressure so blood pressure should be monitored. In addition, patients should be carefully monitored for dysphagia. KOVANAZE is not recommended for use in patients with a history of frequent nose bleeds. Concomitant use of monoamine oxidase inhibitors, nonselective beta adrenergic antagonist, or tricyclic antidepressants may cause hypertension and is not recommended. Discontinue use of oxymetazoline-containing products 24 hours prior to KOVANAZE administration. Avoid concomitant use of intranasal products. The most common adverse reactions to KOVANAZE occurring in >10% of patients include a runny nose, nasal congestion, nasal discomfort, sore throat, and watery eyes.
