Your Comfort Is Not an Afterthought

At MyOBGYN, we believe that no woman should have to white-knuckle her way through a gynecologic procedure. Whether it is a routine Pap smear that makes you tense or an IUD insertion you have been putting off because of what you have heard about the pain, we want you to know something: you deserve better, and now we can offer it.

We are proud to introduce Pro-Nox to our practice, a patient-controlled comfort system that delivers a safe blend of nitrous oxide and oxygen to help you feel calmer, more relaxed, and more in control during your visit.

What Is Pro-Nox?

Pro-Nox is an FDA-cleared analgesic system that delivers a fixed 50/50 mixture of nitrous oxide (sometimes called “laughing gas”) and oxygen through a handheld mouthpiece. You breathe in when you want relief and stop when you do not need it. It is that simple.

This is not general anesthesia. You will not “go under.” You stay fully awake, fully aware, and fully in control of your own comfort the entire time. The effects begin within a few breaths and wear off within minutes after you stop, which means you can drive yourself home and get back to your day with no downtime.

Pro-Nox has been trusted by more than 9,000 medical practices across the United States and Canada, and the same 50/50 nitrous oxide and oxygen blend has been used safely in labor and delivery settings for over a century.

Why We Added Pro-Nox to Our Practice

We listen to our patients. We know that anxiety and discomfort are real barriers to care. Some women delay important procedures, cancel appointments, or avoid recommended treatments because they are worried about pain. That is not something we are willing to accept.

In 2024, both the CDC and the American College of Obstetricians and Gynecologists (ACOG) issued updated guidelines urging providers to take patient pain more seriously during gynecologic procedures, particularly IUD insertions. These guidelines called for a patient-centered approach to pain management, recognizing that the experience of pain is individual and influenced by factors including past trauma and anxiety.

How Pro-Nox Works During Your Visit

There is nothing complicated about using Pro-Nox. Here is what to expect:
Before your procedure begins, your provider will offer Pro-Nox as an option. If you choose to use it, you will be given a disposable mouthpiece connected to the Pro-Nox system. You hold the mouthpiece yourself and breathe in through it whenever you feel you need relief. The system only delivers the nitrous oxide and oxygen blend when you inhale, so you are always in complete control of how much you receive and when you receive it.

Within just a few breaths, you will begin to feel a sense of calm and relaxation. Many patients describe it as taking the edge off, easing both physical discomfort and the mental tension that can make procedures feel worse than they need to. You remain conscious and responsive throughout.

When the procedure is finished, or when you simply stop breathing through the mouthpiece, the effects begin to clear within minutes. There is no grogginess, no lingering sedation, and no need for a driver. You walk out the same way you walked in, just with one less thing to worry about.

Which Procedures Can Pro-Nox Help With?

Pro-Nox can be used with a wide range of in-office gynecologic and obstetric procedures, including:

IUD Insertions and Removals

IUD pain has become one of the most talked-about topics in women’s health, and for good reason. Many women experience significant discomfort during placement, and some avoid this highly effective contraceptive method entirely because of it. Pro-Nox can help take the edge off, making the process more manageable and less intimidating.

Pap Smears and Pelvic Exams

These are routine and essential, but “routine” does not mean comfortable for everyone. If you experience anxiety during pelvic exams, have a sensitive cervix, or find that past experiences have made these visits stressful, Pro-Nox can help you feel more relaxed so your provider can do their best work.

Endometrial and Cervical Biopsies

When a biopsy is recommended, it is because your provider needs answers. The last thing that should stand between you and important diagnostic information is fear of discomfort. Pro-Nox provides rapid relief during tissue sampling procedures, helping you stay calm while your provider gets the samples they need.

Colposcopy and Hysteroscopy

These diagnostic procedures allow your provider to take a closer look when something needs further evaluation. Both can cause cramping and anxiety. Pro-Nox helps ease both so you can get through the exam without unnecessary distress.

Feminine Rejuvenation and Incontinence Treatments

Treatments for vaginal dryness, laxity, or urinary incontinence can be life-changing, but the procedures themselves can cause discomfort that makes some women hesitate. Pro-Nox removes that barrier so you can access the care that improves your quality of life.

Labor and Delivery

For women who prefer a less medicated birth experience or who cannot receive an epidural, Pro-Nox is a fast-acting option that has been used in labor and delivery settings around the world for decades.

Is Pro-Nox Safe?

Yes. The 50/50 blend of nitrous oxide and oxygen used in Pro-Nox has an extensive safety record spanning more than 100 years of use in medical settings worldwide. It is non-addictive and has been shown to reduce the need for opioids and other pain medications.

Because you self-administer Pro-Nox through a demand valve that only releases the gas when you inhale, there is no risk of over-administration. If you stop breathing through the mouthpiece at any point, the delivery stops immediately.

Pro-Nox is not appropriate for everyone. Your provider will review your medical history before recommending it. It is generally not recommended for patients in their first trimester of pregnancy, patients with vitamin B12 deficiency or certain types of anemia, patients with COPD or active respiratory conditions, or patients who have had recent middle ear surgery.

What Does Pro-Nox Cost?

Pro-Nox is an elective comfort service and is not covered by insurance. Ask office for pricing when scheduling. The fee covers your use of the system for the duration of your procedure. Many patients find that Pro-Nox is eligible for reimbursement through Health Savings Accounts (HSA) or Flexible Spending Accounts (FSA).

You Should Not Have to Choose Between Necessary Care and Comfort

Too many women put off procedures because they dread the experience. At MyOBGYN, we refuse to let discomfort be the reason you delay the care you need. Pro-Nox is one more way we are putting you in control of your health, your body, and your experience in our office.

Frequently Asked Questions About Pro-Nox

What does Pro-Nox feel like?

Most patients describe the sensation as a wave of calm and relaxation. Some say it feels like a light “happy buzz,” similar to having a glass of wine. Others feel slightly giggly or just noticeably less tense. You do not feel “out of it” or disconnected. You can still talk to your provider, follow instructions, and remain aware of what is happening. The feeling begins within a few breaths and fades within minutes once you stop inhaling.

Is Pro-Nox the same as laughing gas at the dentist?

Not exactly. Dental offices typically use nitrous oxide at concentrations up to 70%, and the dentist controls how much you receive. Pro-Nox uses a fixed 50/50 blend of nitrous oxide and oxygen, a lower concentration, and you control the delivery entirely yourself through a handheld mouthpiece. You breathe in when you want relief and stop when you do not. This self-administered design is a key safety feature that prevents over-administration.

Will Pro-Nox make me say or do things I would not normally do?

No. Pro-Nox is not a sedative and does not impair your judgment or lower your inhibitions the way general anesthesia or certain medications can. You remain fully conscious and in control of what you say and do. Some patients become more relaxed or talkative, but you will not lose awareness or behave in ways that feel out of character.

Can I use Pro-Nox instead of an epidural during labor?

Pro-Nox is not a replacement for an epidural. An epidural blocks pain signals from the lower body and provides significantly stronger pain relief. Pro-Nox reduces pain perception and anxiety but does not eliminate pain entirely. However, for women who want a less medicated birth experience, cannot receive an epidural due to medical reasons, or want comfort during early labor before an epidural is placed, Pro-Nox can be a helpful option. Your provider can help you decide how Pro-Nox fits into your birth plan.

What are my pain management options for IUD insertion?

In 2024, both the CDC and ACOG updated their guidelines to recommend that providers discuss pain management options with patients before IUD placement. Available options can include over-the-counter anti-inflammatory medications (though research suggests limited effectiveness), topical or injected lidocaine, and analgesic systems like Pro-Nox. At MyOBGYN, we offer Pro-Nox as one of the tools available to help manage both the pain and the anxiety associated with IUD insertions. Talk to your provider about which combination of approaches is right for you.

Is there a way to make my Pap smear or pelvic exam less stressful?

Yes. If you experience anxiety or discomfort during routine gynecologic exams, Pro-Nox can help. You can use it before and during your exam to take the edge off, which not only makes the experience more comfortable for you but also helps your provider get the best results. A relaxed patient allows for a more thorough and accurate exam.

Can I request Pro-Nox for any procedure at MyOBGYN?

Pro-Nox is available for a wide range of in-office procedures and exams, including IUD insertions and removals, Pap smears, pelvic exams, biopsies, colposcopy, hysteroscopy, feminine rejuvenation treatments, and labor and delivery. If you are unsure whether Pro-Nox is appropriate for your specific visit, ask when you schedule your appointment and your provider will advise you.

How much does Pro-Nox cost at MyOBGYN?

Pro-Nox is an elective comfort service and is not covered by insurance. Ask office for pricing when scheduling. Many patients use Health Savings Account (HSA) or Flexible Spending Account (FSA) funds to cover the cost.

Does Pro-Nox have any side effects?

Side effects are uncommon and typically mild. Some patients experience brief dizziness, light-headedness, or mild nausea, which resolve quickly once you stop inhaling. Staying well-hydrated before your appointment can help minimize these effects.

Can I use Pro-Nox if I am pregnant?

Pro-Nox has been used in labor and delivery settings for decades and is considered safe for use during active labor under provider supervision. However, it is not recommended for patients in their first trimester of pregnancy. Your provider will review your specific situation and advise you.

How is Pro-Nox different from taking a Valium or pain pill before my appointment?

Oral medications like Valium or prescription pain relievers take 30 to 60 minutes to take effect, can leave you groggy for hours, and require someone else to drive you home. Pro-Nox takes effect in seconds, you control the dose in real time based on what you are feeling, and it clears your system within minutes. There is no pre-medication wait time, no lingering sedation, and no need for a driver.
