How to Renew Your CPAP Prescription Online (US Guide)
If you use CPAP therapy, your prescription isn't just for the machine in the US it's also required to buy complete masks and certain equipment. When that prescription expires or goes missing, resupplying can stall. The good news: in most cases you can renew your CPAP prescription online, without a new in-person clinic visit. Here's how it works.
Why you need a valid CPAP prescription
In the United States, CPAP and BiPAP machines and complete mask systems are FDA Class II medical devices. That means a valid prescription is required to purchase them. Replacement parts like cushions, filters, tubing, and headgear are generally available without a prescription — but the machine and a complete, assembled mask are not.
A prescription confirms the therapy is appropriate for you and specifies your pressure settings. Keeping it current keeps your resupply on schedule.
Who can renew a CPAP prescription online
Online renewal is designed for people who already have a diagnosis of sleep apnea and have used CPAP therapy before. If you've had a sleep study in the past and simply need your prescription updated or reissued, you're typically a good candidate for online renewal.
If you've never been diagnosed, you'll usually need a sleep study first — many of these can now be done at home — before a prescription can be issued.
How online CPAP prescription renewal works
The process is usually straightforward and takes only a short time:
- Complete a brief online health questionnaire about your therapy history and current CPAP use.
- A licensed provider reviews your information — and, where required, conducts a short telehealth consultation.
- Your renewed prescription is issued electronically, often within one to two business days.
- You use it to order your machine, mask, or complete system and get back on your resupply schedule.
How long a CPAP prescription is valid
Prescription validity can vary. Many CPAP prescriptions are written to last a set number of years, after which a renewal is needed to continue purchasing prescription-required equipment. If you're unsure whether yours is still valid, renewing online is a simple way to stay current rather than finding out at checkout.

Frequently asked questions
Can I buy a CPAP machine without a prescription in the US?
No. CPAP and BiPAP machines are prescription-required medical devices in the United States. A complete, assembled mask also requires a prescription. Individual replacement parts — cushions, filters, tubing, headgear — generally do not.
Do I need a new sleep study to renew my prescription?
If you already have a sleep apnea diagnosis and prior CPAP use, you usually do not. A new sleep study is typically only needed for first-time patients without a prior diagnosis.
How long does online renewal take?
In many cases a renewed prescription is issued within one to two business days after your information is reviewed.
Can I renew if I bought my machine somewhere else?
Yes. Online renewal is about your therapy and diagnosis history, not where you bought your equipment.
Is online prescription renewal available nationwide?
Availability can depend on your state. If you have questions about your specific situation, reach out before ordering and we'll help you understand your options.
