Pro-Nox for Hysterosalpingography

---

Undergoing a hysterosalpingogram (HSG) or fallopian tube recanalization (FTR) is an essential step in your fertility journey. While these procedures are typically quick and well-tolerated, we understand that some patients may feel anxious about potential discomfort. To help make your experience as comfortable as possible, we offer Pro-Nox, a patient-controlled nitrous oxide system, along with additional pain relief options such as ibuprofen and acetaminophen.

During the exam, you may feel cramping or discomfort when the catheter and contrast are inserted into your uterus and fallopian tubes. This sensation can resemble menstrual cramps and may be sharp or dull. Some women experience a brief, intense cramp as the dye is injected.

 To help minimize discomfort, we provide several pain relief options:

• Pro-Nox (Nitrous Oxide & Oxygen): A safe, fast-acting inhaled gas that lets you control your own pain and anxiety relief. The effects are felt within seconds and wear off quickly, so you can return to normal activities immediately.
• Ibuprofen or Acetaminophen: Taking an over-the-counter pain reliever about 30–60 minutes before your procedure can help reduce cramping. It is also recommended for post-procedure discomfort.
• Relaxation Techniques: Deep breathing and calming exercises can further ease any tension during the procedure. 

 Hysterosalpingography (HSG) and fallopian tube recanalization (FTR) are essential diagnostic and therapeutic procedures, but some patients may experience cramping or mild discomfort. Pro-Nox can help by

✅ Providing immediate relief – Effects are felt almost instantly.
✅ Allowing you to stay in control – You decide when and how much to use.
✅ Reducing anxiety – Helps you stay relaxed throughout the procedure.
✅ Wearing off quickly – No lingering drowsiness, so you can resume daily activities right away. 

If you choose Pro-Nox, you will have a small mouthpiece to inhale the gas as needed. You will remain awake and alert while experiencing relief from discomfort. Once the procedure is complete, the effects dissipate within 2-3 minutes, allowing you to continue your day as usual.

Most patients are good candidates for Pro-Nox and can benefit from taking ibuprofen or acetaminophen beforehand. If you have concerns about discomfort, let us know—we’re happy to discuss the best pain management approach for you. At Interventional Radiology, P.C., we are committed to providing expert, compassionate care while ensuring your experience is as smooth and comfortable as possible. 

We offer Pro-Nox (nitrous oxide) for $75 during hysterosalpingogram (HSG) exams to help reduce discomfort and anxiety. This service is not covered by insurance because it is considered an optional comfort measure rather than a medically necessary treatment. Patients appreciate Pro-Nox's quick onset, control over use, and ability to return to normal activities immediately after the procedure.
