The name of your medicine is Medical Nitrous Oxide. Medical Nitrous Oxide is supplied as a pure gas containing only Nitrous Oxide. It does not contain any other ingredients

1. what is medical nitrous oxide and what it is used for?

Medical Nitrous Oxide is an inhalation gas (a gas that is breathed in). It is colourless and odourless. It is supplied as a pressurised gas in a gas cylinder with a valve to control the outflow of the gas.

It is used as an anaesthetic during surgery and is used to relieve pain when rapid-onset powerful short-term relief of severe pain is needed.

It has anaesthetic effects and can make you relax and send you to sleep. It can also relieve pain by acting on chemical messengers within your body which send messages to the brain when you are injured.

2. before you use medical nitrous oxide

Do not smoke or allow those near you to smoke during treatment with Medical Nitrous Oxide. Nitrous Oxide helps things burn.

Do not allow naked flames near you when you are using Medical Nitrous Oxide

If you suffer from any medical complaint where air is trapped within your body and it might be dangerous for this air to expand or if you are taking strong drugs to make you very sleepy you should not take Medical Nitrous Oxide. Please consult your doctor.

If you have received an injection of gas into your eyes (intraocular injections) within the last 3 months, please consult your doctor.

3. how to use medical nitrous oxide

Always follow the instructions given to you by your doctor. Do not stop treatment or change your treatment without consulting your doctor first.

You will normally use Medical Nitrous Oxide by breathing the gas in through a mask.

Only use the equipment supplied to you for use with your Medical Nitrous Oxide

All equipment used with the Medical Nitrous Oxide should be kept clean and dry. Do not use oil or grease on any equipment that is used with Medical Nitrous Oxide.

Your doctor or nurse will decide how much Nitrous Oxide you need.

You must always use at least 21% oxygen with nitrous oxide.

If you are at altitude, you should use at least 30% oxygen with nitrous oxide.

If you use Medical Nitrous Oxide for more than 24 hours, or if you use the gas more frequently than every four days, your doctor will take blood tests to check your red and white blood cells.

You must always use the cylinder upright with the valve at the top. Although Medical Nitrous Oxide is gas when it comes out of the cylinder, inside it is liquid. If you use the cylinder on its side this liquid may come out and it may cause burns if in contact with your skin.

Also, you must always open the valve slowly as rapid opening may cause the escaping gas to become liquid again and cause burns if in contact with your skin.

Your doctor will tell you how long your treatment with Medical Nitrous Oxide will last.
