Equanox is an inhalation gas (a gas that is breathed in). It is colourless and odourless. It is
supplied in as a pressurised gas in a gas cylinder with a valve to control the outflow of the
gas.
It relieves pain by acting on chemical messengers within your body which send messages
to the brain when you are injured.
It is used to relieve pain when rapid-onset powerful short-term relief of severe pain is
needed.

Before you use Equanox

Do not smoke or allow those near you to smoke during treatment with Equanox as it
helps things burn.
If you suffer from any medical complaint where air is trapped within your body and it
might be dangerous for this air to expand you should not take Equanox. Please consult
your doctor.
Before taking Equanox you must make sure it has been stored above 10°C for at least 24
hours.
