Penthrox for Vasectomies
Fast-Acting Relief. Greater Comfort. More Control.
At SNIP Vasectomy NZ, we’re dedicated to delivering the most comfortable and confident vasectomy experience possible. That’s why we offer Penthrox ($295) – a self-administered, fast-acting pain relief option that helps you stay relaxed and in control during your procedure.
What is Penthrox?
How Penthrox works during your vasectomy
With Penthrox, you remain awake, alert, and in charge of your comfort:
- You’ll be shown how to use the inhaler just before your procedure.
- Relief begins within 6–8 breaths – you inhale as needed.
- The effects last for the duration of the vasectomy and wear off quickly afterward.
- You remain conscious, calm, and able to communicate with your doctor.Penthrox works alongside local anaesthetic, helping reduce discomfort from both the anaesthetic injection and the procedure itself.

Is Penthrox safe?
Yes. Penthrox has an excellent safety profile when used in the low doses required for brief procedures like vasectomy.
- The inhaler contains just 3ml of methoxyflurane – far below older anaesthetic doses.
- An activated carbon chamber captures exhaled vapor to protect staff and others nearby.
- It is not suitable for people with:
- personal or family history of malignant hyperthermia
- Certain liver or kidney conditions
- Specific drug interactions (discussed with your doctor)
Frequently asked questions
Will Penthrox make me feel sick or dizzy?
Most people tolerate it very well. You may feel lightheaded or relaxed, but these effects wear off quickly once inhalation stops.
Can I drive after using Penthrox?
Yes – in most cases, you can drive 30 minutes after your procedure. Your doctor will confirm this before you leave.
Is Penthrox right for everyone?
It is suitable for most healthy adults. We’ll review your medical history to ensure it’s appropriate for you.
Will I still get a local anaesthetic?
Yes. Penthrox works alongside the anaesthetic to reduce discomfort from the injection and enhance your overall comfort.
How does it compare to other options?
Penthrox acts faster than oral meds and doesn’t cause the grogginess of sedation. It offers real-time control and effective relief — without compromising your awareness.
