FDA Requirements for Selling CPAP Machines Online

CPAP (Continuous Positive Airway Pressure) machines are among the most commonly sold medical devices online. They treat obstructive sleep apnea, a condition affecting roughly 30 million Americans. But selling CPAP machines online comes with strict FDA requirements that every retailer must understand.

CPAP Machines as FDA-Regulated Devices

The FDA classifies CPAP machines as Class II medical devices under product code BZD. This classification means they carry moderate risk and are subject to special controls, including the requirement for a valid prescription before sale.

Under 21 CFR 801.109, CPAP machines are labeled as prescription devices. The labeling must include the statement: "Caution: Federal law restricts this device to sale by or on the order of a licensed practitioner." This restriction applies to all sales channels, including ecommerce.

What Constitutes a Valid CPAP Prescription?

A valid prescription for a CPAP machine typically includes:

• Patient's full name — must match the person placing the order
• Prescriber's name and credentials — usually an MD, DO, NP, or PA
• Prescriber's NPI number — the unique 10-digit identifier from the NPPES registry
• Date of the prescription — most states consider prescriptions valid for one to two years
• Diagnosis or indication — typically obstructive sleep apnea (ICD-10 code G47.33)
• Device specifications — pressure settings, whether auto-titrating or fixed-pressure
• Prescriber's signature

The 2024 FDA Enforcement Shift

In recent years, the FDA has increased its focus on online sales of CPAP equipment. Several enforcement actions have targeted retailers who sold CPAP machines without verifying prescriptions. Notable actions include warning letters to online marketplaces and direct-to-consumer websites.

The FDA has also clarified that CPAP supplies and accessories — such as masks, tubing, and filters — generally do not require a prescription when sold as replacement parts. However, the base CPAP unit and any device that delivers positive airway pressure always requires one.

State-Level Requirements

Beyond FDA regulations, many states have their own rules for DME retailers:

• State licensing — some states require a DME license or permit to sell CPAP equipment
• Prescription validity periods — some states set their own expiration timelines
• Pharmacist or clinician oversight — certain states require a licensed professional to verify each prescription
• Record retention — states may require keeping prescription records for 5-7 years or longer

Common Compliance Mistakes

Online CPAP retailers frequently make these mistakes:

1. Selling without any prescription gate — allowing customers to add CPAP machines to cart and check out without uploading a prescription
2. Accepting self-attestation — letting customers check a box saying they have a prescription without actually collecting and verifying it
3. Not verifying the prescriber — accepting prescriptions without checking the NPI number against the NPPES database
4. Ignoring expiration dates — not checking whether prescriptions are still within their valid period
5. Inadequate record-keeping — failing to maintain an audit trail of prescription documents and verification decisions

Consequences of Non-Compliance

Selling CPAP machines without proper prescription verification can lead to:

• FDA warning letters (publicly searchable and damaging to reputation)
• Product seizure and import alerts
• Civil monetary penalties up to $15,000 per violation
• Payment processor account suspension or termination
• Loss of supplier relationships
• State-level enforcement actions and license revocation
