CPAP Therapy

Why Can’t I Get a CPAP Machine Without a Prescription?

Updated: March 4, 2019

Did you know that a prescription is required to get started with CPAP therapy? Below we discuss what goes into a CPAP prescription, who can write a CPAP prescription, and what to think about when buying your first CPAP machine.

Why You Need a Prescription to Purchase Certain CPAP Equipment

You’ll need to have a prescription in hand when buying a CPAP machine, mask, or humidifier. These devices are classified by the FDA as Class II Medical Devices1, and it’s illegal to sell a CPAP machine, CPAP mask, or CPAP humidifier without having a valid prescription.

Be very careful when dealing with a company that tries to sell you a CPAP machine without a prescription. Not only are they breaking the law, but the machine you get may not work correctly or could be set up wrong.

Why is it Important to Get a CPAP Prescription?

Prescriptions are important because it tells you exactly what is required for successful CPAP therapy. Here are some of the things a prescription usually covers:

And that’s just the beginning. Prescriptions are also important because they make recommendations based on the results of your sleep study. A sleep study provides data about how you sleep and where the problems are. Without the results, you’re really just guessing. A prescription turns the insights from the sleep test and makes it actionable, giving you access to successful treatment.

If you already have a prescription on file somewhere, there are ways of getting it without needing to see a doctor. We’ll cover this in greater detail later in the article.

Can I Get a CPAP Without a Prescription?

It’s possible to get a used CPAP machine without a prescription from a private seller, but it’s not recommended. Sometimes you can find a recycled CPAP machine from a second-hand seller on the internet, but be careful. A used machine will come with its own problems. These are the risks:

  • breathing in the previous owner’s germs
  • getting sick
  • purchasing a machine at the end of its life expectancy
  • features not working
  • buying the wrong type of machine (you may need a BiPAP, for example)

There are many more hidden dangers to buying a second-hand CPAP machine, which we won’t list here. But it’s better to get the right equipment right off the bat because your therapy stands a stands a better chance of working for you than it does relying on a machine someone else used. If you need assistance on getting a CPAP machine, read our CPAP machine buying guide or call 1-800-356-5221.

How Long is it Valid?

Some prescriptions have a finite expiration date or can be valid for life, as judged by how many “refills” or other indicators a doctor writes on the prescription. Here are some examples of how time limits can be written:

  • “Lifetime” or “99 Months”: These are truly unlimited. You can get as many as you need.
  • “X refills”: that’s the total amount of machines you can purchase on that prescription. So if it states 5 refills, you’d get 5 machines max, and have to see your doctor again to get your 6th..
  • “Valid until MM/DD/YYYY”: Prescriptions with an expiration date can’t be used after that date

How to Get a CPAP Prescription?

Here are the steps to getting a prescription from a doctor:

  1. Schedule an appointment to discuss your sleep with your doctor.
  2. The doctor will usually order a home sleep test.
  3. You’ll setup the test, and fall asleep like you normally would.
  4. The next morning you’ll send the sleep test to the remote lab.
  5. The recommendations are sent to your doctor, who writes the prescription.

Your doctor may order your sleep study be done in a sleep lab. This usually isn’t a reason to worry. Home sleep studies can only be used to check for apnea, and if that’s not the source of your problem, you’ll need to go into a sleep lab for your sleep study.

Some companies offer home sleep test kits, which include a prescription if needed. A remote lab sends the sleep test to you. After the results are measured, the doctor from the lab will send you a prescription via email. Many of these companies typically charge around $180 for this service. This is a great option for anyone who has limited access to healthcare.

Does Someone Need a Prescription for a Sleep Study?

A person doesn’t need a prescription for a sleep study. By going to a 3rd party company online you can order it yourself, and have it delivered to you. If you go through your doctor to get the prescription, they’ll order it for you, and you won’t need to worry about it. Thanks to telemedicine, sleep studies are easier to come by and more readily available than they used to be, so you shouldn’t worry about getting a new one.

How Much Does a Sleep Study Cost?

In our interview with Dr. Amie Stringfellow she revealed the true cost of a sleep study.

  • In-home sleep studies typically cost $180
  • In-lab sleep studies can cost as much as $5,000

Insurance can cover some of the cost, but it all depends on your deductible. Medicare will cover most types of sleep studies, but you’ll need to pay 20% of the Medicare negotiated amount2.

Who Can Write a Prescription?

You may not realize this, but almost any U.S. based doctor (including your family doctor) can write a prescription for a CPAP machine. It doesn’t have to be a specialist. In a pinch, there’s a chance your doctor could give you a fresh prescription if your old one expired. Here’s a list of professionals who can get you a prescription:

  • Dentist
  • Doctor of Osteopathy
  • Nurse Practitioner
  • Physician Assistant
  • M.D. Psychiatrist
  • Family Doctors

…And that’s not even a complete list!

How Do I Track Down My Old Prescription?

Did you know? offers a free service helping anyone track down old prescriptions. We will send a message to a doctor’s office, asking them for your prescription, so you don’t have to. If your doctor needs help with writing a valid prescription for a CPAP machine, mask, or humidifier we can tell them what topics need to be covered in order for to be able to process the order.

With a little sleuthing online, you also can find your previous doctor and contact his or her office. Just search the doctor’s name or practice name online to track down the office. Give them a call and see if they still have it.

If you previously worked with another DME, there’s a chance you can get the prescription from them. They should still have it on file. They can release it to you, and you can give it to your CPAP supplier of choice.

Where Does Someone Purchase CPAP Equipment?

After getting the prescription, the hard part’s over! Now it’s time for your first or next CPAP machine, mask, or humidifier. There are usually two ways you can get your CPAP equipment:

  • Buy Online with a Company Like
  • Go Through Your Insurance Company and Its DME (or Durable Medical Equipment provider)

Each method has its own advantages and drawbacks, which we go over in greater detail in our article about CPAP machine cost and insurance.

    Why is a prescription needed for an auto-cpap: it is doing all the calibration real-time, sans doctor.

    • The requirement for a prescription is a legal requirement and not an internal policy that we decided on. It’s also better to have a doctor monitoring your progress, and make adjustments if need be.

  2. What happens when you know your partner has sleep apnea (snoring, fatigue, heart rate spikes in the night, high blood pressure, high resting heart rate) but the sleep study doesn’t support it? My husband (finally after two years of begging) had a sleep study. He said he hadn’t slept that well in years, and the study showed just 4 apnea episodes per hour so “he’s fine.” It also showed that he doesn’t snore. What?!? He sleeps on the couch so I can sleep his snoring is so bad. What do we do then? I am afraid I’m going to find him one morning. I’m so frustrated.

    I have had a machine for years and now mine has been destroyed. I can’t get an appointment with my doctor for 5 months to get. New one. What the hell am I supposed to do? No sleep till these idiots will see me? This is not right, I just need a new machine and I am willing to pay for the machine with or without insurance.

    • Hi Lee,

      I’ve notified a CPAP expert who will be reaching out to you via email. Have you tried tracking down your old prescription? There are a number of places that might still have it. Your doctor may have it on file, the place where you get supplies might have it, any number of places could have your CPAP prescription. Sometimes it can take a little sleuthing, but once you find it, you’re back in business with a CPAP machine.

  4. Even though you have had my prescription on file for years I am always asked to submit a new one. A prescription for these machines once obtained is good for a lifetime so why are you always requiring a new one? Now that I need a new machine and could die without one you are requiring me to spend an additional $300 on a new prescription (Doctor’s visit more then 1 year) because they won’t send a new one without it. Just another medical scam to extract more dollars from sick people’s pockets.

    • Hey There!

      I am going to put you in touch with one of our CPAP experts, who will be in contact with you to help resolve your issue.

  5. I did the sleep study and by the time they contacted me to get a machine months later, I had lost my insurance. They got off the phone with me when they found out there was no insurance and didn’t even ask if I could afford one without. I did find out my settings and I know it drastically changes my life. But I don’t know how to get a machine now. And it would be a stretch for me to afford one. But I definitely can’t afford another sleep study and a machine.

    •, in 2018, recently partnered with a financing company called Bread to help split the cost of the machine into monthly payments. If you have questions, you can reach out to at 1-800-356-5221.

    • Hi Richard, we know that obtaining a prescription can be really frustrating. We will be more than happy to make an attempt at obtaining the prescription on your behalf. We will need to have your doctor’s contact information such as name, phone, fax number, and the address to your doctor. Keep in mind that the prescription does not have to come from your sleep specialist. If you visit your Primary Care Physician on a regular basis, or a different medical doctor that may be willing to write a prescription for you that will work also. If you are interested in this free service, please contact our customer service department at 1-800-356-5221 and we will be happy to help you.

  7. My Dr. is ordering a new sleep study I can do at home, but I might have a prescription from a while ago. How would I go about finding out?

    • Hey Aaron, to confirm if you have an older prescription, you may want to speak with your doctor to see if they have any record of your previous prescription. also offers a free service where we can request a copy of your prescription from your doctor on your behalf.

      If you would like to take advantage of this option, please feel free to contact us, at 1-800-356-5221 and provide us with your doctor’s contact information.

      I hope this helps, have a great day!

  8. I just realized that a prescription is required to buy an auto cpap machine. I promised my dad who is living in another country. What does prescription from doctor help for using the machine? it is automatically!

    this is crazy! 🙁

    • Hi Wei, I am very sorry about any inconvenience that you may experience in obtaining a prescription for your father. In answer to your question, the prescription is required per FDA guidelines. The prescription can however, come from your father’s Primary Care Physician instead of a Sleep Center.

  9. I too have run into conflicts with my doctors office. Saw my doctor and agreed to a home sleep study. Saw the doctor and he wanted a sleep study done at the hospital so the machine would fit right. I did the hospital sleep study. I had an appointment to see the doctor for the third time. After the Cover-19 stay at home order came I called the doctors office and said I really didn’t want to come in. The office insisted I had because of medicare. I cancelled the appointment. They will not give me a prescription.

    So two doctors visits and two sleep studies and they won’t give me a prescription because medicare won’t let them according to them.

    What options do I have to get a cpap?

    This is crazy!!!!!

    • Hi John, my apologies for the delayed response. I’m so sorry to hear about the difficulties you’re having with obtaining a prescription for your machine. Usually, Medicare, has no bearing on your doctor providing you with a prescription. However, if their required process isn’t completed, they may not cover the CPAP machine.

      Since per the FDA guidelines, a prescription is required in order for you to purchase a machine, you may try speaking with the doctor once more to see if for the time being they can offer a prescription based off the hospital sleep study.

      Most offices are understanding of patients not being able to come into the office, or even ask your doctor, if there is an option for a virtual visit due to COVID-19. Also, keep in mind that you don’t have to get the prescription from a sleep specialist, your primary care physician can write a prescription for you as well.

      We wish you the best!
