Use ofNitrous Oxide Medicinalwith other medicines
Tell your doctor if you are taking, or have recently taken, any other medicines, including those obtained without a prescription.
Nitrous oxide enhances the hypnotic effects of intravenous or inhaled anesthetics (thiopental, benzodiazepines, morphinics, halogenated), so the dosage of these should be reduced.
You should also inform your doctor if you are taking medicines that contain methotrexate (e.g., for rheumatoid arthritis).
Pregnancy and Breastfeeding and Fertility
Pregnancy
During pregnancy, it is recommended not to exceed a concentration of 50% of nitrous oxide in the inhaled mixture.
Obstetric Anesthesia:
Due to the rapid passage through the fetoplacental barrier, it is recommended to interrupt the administration of nitrous oxide if the time between the induction of anesthesia and the extraction of the fetus exceeds 20 minutes.
Avoid using nitrous oxide in case of fetal distress.
Obstetric Analgesia:
The use of nitrous oxide for this indication can only be performed if a safety flowmeter is available that prevents the administration of nitrous oxide at a concentration greater than 50%.
Breastfeeding
Consult your doctor before using the medicine.
Driving and Using Machines
It is recommended not to drive vehicles and not to use machines during the 24 hours following anesthesia with nitrous oxide.

Nitrous oxide medicinal must be used exclusively in a mixture with medical oxygen, the oxygen concentration (FiO2) should never be less than 21%.
To avoid accidents, the following guidelines must be respected:
- The projection of liquid could cause severe cryogenic burns (very cold). In case of burns, rinse abundantly with water.
- Ventilate if possible the place of use.
- Check the good condition of the materials before use.
- Perform any manipulation of nitrous oxide containers wearing clean gloves adapted to this use and without grease, and protective glasses.
- Never touch the cold or frosted parts of the material.
- Handle the material with clean and grease-free hands.
- Use a specific connector for nitrous oxide.
- Use connection hoses to wall outlets provided with specific connections for nitrous oxide medicinal.
- Do not use an intermediate connector that allows connecting two devices that do not fit.
- Check beforehand the compatibility of materials in contact with nitrous oxide medicinal, in particular use connection gaskets to the manoreducer provided for this gas. Check the condition of the gaskets.
- Do not smoke, do not approach a flame, and do not grease.
IMPORTANT:
- Never introduce this gas into a device that may be suspected of containing combustible bodies, particularly fatty bodies.

- Do not use aerosol generators (lacquers, deodorants, etc.), solvents (alcohol, gasoline, etc.) on the material or in its proximity.
- When the ambient temperature is low, the flow may decrease, even interrupt, due to insufficient pressure.
- Avoid using nitrous oxide medicinal at a temperature below 0°C to avoid a drop in pressure in case of intensive use.
- Never use nitrous oxide medicinal for tightness tests, for powering pneumatic tools, and for blowing pipes.
- The average exposure limit value (for 8 hours) to nitrous oxide is set at 25 ppm for exposure of personnel.
Perform systematic ventilation of the place of use, evacuating the exhaled gases to the outside and avoiding places where they could accumulate. It is convenient, before any use, to ensure the possibility of evacuating gases in case of an accident or unexpected leak.
