Geriatric Use FULL PRESCRIBING INFORMATION 1 INDICATIONS AND USAGE TYMBION, a combination of an amide local anesthetic and an alpha- and beta-adrenergic agonist, is indicated for the induction of local anesthesia of the tympanic membrane via iontophoresis using the Tula Iontophoresis System in pediatric (aged 6 months and older) and adult patients undergoing tympanostomy tube placement using the Tula Tube Delivery System. Limitations of Use • TYMBION is for use ONLY with the Tula Iontophoresis System and cannot be used with any other iontophoresis device. • TYMBION is not for use alone (i.e., without the Tula Iontophoresis System) and is not interchangeable with other lidocaine with epinephrine formulations. 2 DOSAGE AND ADMINISTRATION 2.1 Dosing Each mL of TYMBION contains 20 mg lidocaine HCl, equivalent to 16.2 mg lidocaine, and 10 mcg of epinephrine. The typical volume of the external ear canal for children ages 6 months to 12 years is approximately 0.4 mL to 0.8 mL. The Tula Iontophoresis System tubing and reservoir accommodates approximately 0.6 mL. 2.2 General Instructions Use TYMBION only in conjunction with the Tula Iontophoresis System. Full instructions for use of the Tula Iontophoresis System are provided with the Iontophoresis System. In brief, instill TYMBION into the external ear canal via Earsets connected to fitted Earplugs. The Tula Iontophoresis System applies an electrical current to the solution, which causes lidocaine and epinephrine to penetrate the tympanic membrane. After approximately 10 minutes, iontophoresis is complete and TYMBION is drained from the external ear canal by gravity or wicking. Iontophoresis can extend beyond 10 minutes if the program is paused or current is reduced per the Tula Iontophoresis System instructions for use. Assess adequate local anesthesia by lightly tapping the tympanic membrane with a dull otologic probe or the tip of the Tube Delivery System. • Warm TYMBION to approximately body temperature prior to instilling in the external ear canal [see Warnings and Precautions (5.1)]. • Avoid touching the ear canal wall with otologic instruments [see Warnings and Precautions (5.1)] 2.3 Repeat Administration The safety of repeat iontophoretic administration of TYMBION has not been evaluated in humans, and repeat administration (to the same ear) is not recommended. [see Nonclinical Toxicology (13.2)]. A nonclinical repeat dose study showed mild residual shifts in auditory brainstem response at 28 days after the final repeated dose, likely related to external ear canal debris or inflammation in the external ear canal or tympanic membrane. There was no adverse impact of the repeat TYMBION dosing on ossicular structures, ossicular mobility, cochlear hair cells, or on microscopic inner ear findings. 3 DOSAGE FORMS AND STRENGTH Otic Solution for iontophoretic delivery using only the Tula Iontophoresis System: TYMBION is a sterile, nonpyrogenic solution of lidocaine hydrochloride 2% (20 mg/mL, equivalent to lidocaine 16.2 mg/mL) and epinephrine 1:100,000 (0.01 mg/mL) in water; provided in 20 mL single-patient-use vials for iontophoretic administration using the Tula Iontophoresis System. 4 CONTRAINDICATIONS • Iontophoretic administration of TYMBION is contraindicated in patients with tympanic membrane (TM) perforation(s), or lacerations or abrasions to the external auditory canal. • Iontophoretic administration of TYMBION is contraindicated in patients with a history of sensitivity or allergic reaction to lidocaine HCl, tetracaine, epinephrine, or any hypersensitivity to local anesthetics of the amide type, or any component of the anesthetic drug formulation. • Iontophoretic administration of TYMBION is contraindicated in patients with a familial history of insensitivity to lidocaine or other local anesthetics (e.g., history of inadequate anesthesia with dental local anesthetic agents). 5 WARNINGS AND PRECAUTIONS 5.1 Local (External Ear Canal and Tympanic Membrane) Effects Although not noted during clinical trials, local edema and erythema was noted during preclinical animal studies upon iontophoretic administration of TYMBION. These effects were temporary in nature and generally resolved within 14 days of the procedure. TYMBION should be warmed to approximately body temperature prior to instilling in the external ear canal. Cool drug placed into the ear canal may cause dizziness due to caloric stimulation. TYMBION, when administered with the Tula Iontophoresis System, provides local anesthesia of the tympanic membrane, and not the external ear canal. Avoid impacting the ear canal wall with otologic instruments. 5.2 Middle Ear Effects Iontophoretic administration of TYMBION is contraindicated in patients with perforation
