§ 801.422 Prescription hearing aid labeling. ( a ) *Scope.* This section specifies the labeling requirements for prescription hearing aids. Any hearing aid that does not satisfy the requirements of § 800.30 of this chapter shall be a prescription device. Unless otherwise specified, the requirements in this section are in addition to other applicable requirements, including but not limited to special controls found in the applicable classification regulation in part 874 of this chapter. This section does not apply to group auditory trainers.
( b ) *Definitions for the purposes of this section.* This section uses the following definitions: *Dispenser.* A dispenser is any person, as defined in section 201(e) of the Federal Food, Drug, and Cosmetic Act, engaged in the sale of hearing aids to any member of the consuming public or any employee, agent, salesperson, and/or representative of such a person.
*Hearing aid.* A hearing aid is any wearable device designed for, offered for the purpose of, or represented as aiding persons with or compensating for, impaired hearing.
*Prescription hearing aid.* A prescription hearing aid is a hearing aid that is not an over-the-counter (OTC) hearing aid as defined in § 800.30 of this chapter or a hearing aid that does not satisfy the requirements in § 800.30 of this chapter.
*Rebuilt hearing aid.* A prescription hearing aid is “rebuilt” if the manufacturer has inspected and tested the device, made any necessary modifications to ensure it meets applicable regulatory requirements, including the requirements in this section, and adequately reprocessed the device for the next user.
*Sale.* Sale includes a lease, rental, or any other purchase or exchange for value.
*Used hearing aid.* A hearing aid is “used” if a user has worn it for any period of time. However, a hearing aid shall not be “used” merely because a prospective user wore it as part of a bona fide hearing aid evaluation to determine whether to select that particular hearing aid for that prospective user. A hearing aid evaluation is “bona fide” if it was conducted in the presence of the dispenser or a hearing health professional selected by the dispenser to assist the prospective user in making a determination.
( c ) *Labeling.* A prescription hearing aid shall bear all of the following labeling: ( 1 ) *Outside package labeling.* The outside package of a prescription hearing aid shall bear all of the following: ( i ) *Warnings and other important information.* All of the following shall appear on the outside package: ( A ) *Warning against use in people younger than 18 without prior medical evaluation.*
( B ) *“Red flag” conditions.*
( C ) *Note about device trial options.*
( ii ) *Statement of build condition.* If the prescription hearing aid is used or rebuilt, the outside package shall declare that fact. A sticker under and visible through the outer wrapper will suffice to declare such fact.
( iii ) *Indication of battery information.* The outside package shall indicate the type and number of batteries and whether batteries are included in the package.
( iv ) *Indication of control platform.* That outside package shall indicate whether a mobile device or other non-included control platform is required. The indication must include the type of platform and how the platform connects to the device.
( 2 ) *Labeling, inside the package.* The manufacturer or distributor of a prescription hearing aid shall include a user instructional brochure inside the package and shall make an electronic version available for download without site or customer registration and without requiring purchase of any product or service. The user instructional brochure shall include all of the following: ( i ) The following warnings, which shall appear in the following order and prior to any content except the cover page: ( A ) *Warning against use in people younger than 18 without prior medical evaluation.*
( B ) *“Red flag” conditions, addressed to dispensers.*
( C ) *Warning to dispensers about very high-output devices.*
( D ) *Additional warnings.* Any additional warnings the manufacturer may include prior to the cautions and notices to users in paragraph (c)(2)(ii) of this section.
( ii ) The following cautions and notices for users, which shall appear prior to any content, except the cover page and the warnings under paragraph (c)(2)(i) of this section: ( A ) *Caution about hearing protection.*
( B ) *Caution about excessive sound output.*
( C ) *Caution about components lodging in ear.*
( D ) *Note about user expectations.*
( E ) *Note about reporting adverse events to FDA.*

( viii ) The technical specifications required by paragraph (c)(4) of this section unless such specifications appear in separate labeling accompanying the prescription hearing aid.
( ix ) A description of commonly occurring, avoidable events that could adversely affect or damage the prescription hearing aid, including but not limited to, as applicable, ear wax buildup, drops, immersion in water, or exposure to excessive heat.
( x ) If the hearing aid incorporates wireless technology in its programming or use, appropriate warnings, instructions, and information relating to electromagnetic compatibility and wireless technology and human exposure to non-ionizing radiation.
( xi ) Information on how and where to obtain repair service or replacements, including at least one specific address where the user can go or send the prescription hearing aid to obtain such repair service or replacements.
( xii ) If clinical or non-clinical studies were conducted by or for the manufacturer to support the performance of the prescription hearing aid, a summary of all such studies.
