1. What is Nodolox and what is it used for
Nodolox contains a prepared mixture of nitrous oxide (N2O) and oxygen (O2), 50% of each, and should be used by inhaling the gas mixture.
This medicine can be used in adults and children over 1 month of age. The safety and efficacy of Nodolox in children under 1 month of age have not been established.
The effects of Nodolox
Nitrous oxide makes up 50% of the gas mixture. Nitrous oxide has an analgesic effect, reduces the sensation of pain, and raises the pain threshold. Nitrous oxide also has a relaxing and slightly calming effect. These effects occur through the action of nitrous oxide on the substances that send signals in your nervous system.
The effect of this medicine is lower in children under three years of age.
The oxygen concentration of 50%, about twice that in ambient air, ensures a safe oxygen content in the inhaled gas.
What is Nodolox and what is it used for
Nodolox should be used when rapid-onset and short-duration analgesic effects are desired for pain of mild to moderate intensity and limited duration. Nodolox produces analgesic effects after a few inhalations, and the analgesic effects subside within a few minutes after stopping use.
2. What you need to know before you use Nodolox
Do not use Nodolox:
Before using this medicine, you must inform your doctor if you have any of the following signs/symptoms:
- Gas-filled cavities or gas bubbles:If, as a result of a disease, or for any other reason, it is suspected that there is air in the thorax outside the lungs, or gas bubbles in the blood, or in any other organ. For example, if you have dived with diving equipment and may have gas bubbles in the blood, or if you have been treated with a gas injection in the eye, for example, for a retinal detachment or similar. These gas bubbles can expand and cause damage.
- Heart disease:If you have heart failure or severe impairment of cardiac function, as the mild relaxing effect of nitrous oxide on the heart muscle may further impair cardiac function.
- Central nervous system injury:If you have increased pressure in the brain, for example, as a result of a tumor or cerebral hemorrhage, as nitrous oxide may increase pressure in the brain with a possible risk of damage.
- Vitamin deficiency:If you have been diagnosed with a vitamin B12 deficiency or a folic acid deficiency, but have not received treatment for it, as the use of nitrous oxide may worsen the symptoms caused by the vitamin B12 and folic acid deficiency.
- Intestinal obstruction:If you have severe abdominal discomfort: symptoms that may indicate intestinal obstruction, then Nodolox may further increase intestinal dilation.
Warnings and precautions
Consult your doctor or pharmacist before using Nodolox:
If you need to use this medicine for more than 6 hours in a row, the healthcare professional will perform routine blood tests to ensure that Nodolox has not affected your blood count or how your body uses vitamin B12.
Also, inform your doctor if you have any of the following signs/symptoms:
- Ear problems:such as inflammation in the ear, as this medicine may increase pressure in the middle ear.
- Vitamin deficiency:if you suspect you have a vitamin B12 deficiency or a folic acid deficiency, as the use of nitrous oxide may worsen the symptoms caused by the vitamin B12 and folic acid deficiency.
- If you have or have had drug addiction, as there is a high risk of dependence on nitrous oxide if it is administered repeatedly. Your doctor will decide if treatment with nitrous oxide is possible in your case.
Prolonged or repeated use of nitrous oxide may increase the risk of vitamin B12 deficiency, which can cause damage to the bone marrow or nervous system. The use of nitrous oxide should be accompanied by close clinical supervision and hematological monitoring to evaluate the consequences of a possible vitamin B12 deficiency.
Your doctor will decide if Nodolox is suitable for you.
Children
The success rate is lower in children under 3 years of age.
Nodolox can be used in children who can follow instructions on how to use the equipment. In the treatment of smaller children, or in other patients who are not able to follow instructions, administration should be carried out with the help of a healthcare professional.
This medicine should not be used in children under 1 month of age.
Other medicines and Nodolox
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
If you are taking other medicines that affect the brain or brain function, such as benzodiazepines (tranquilizers) or morphine-like medicines, you should inform your doctor. Nitrous oxide may increase the effects of these medicines. Nodolox in combination with other sedatives or other medicines that affect the central nervous system increases the risk of side effects.
You should also inform your doctor if you are taking medicines that contain methotrexate (e.g., for rheumatoid arthritis), bleomycin (for cancer treatment), furadantin, or similar antibiotics (for infection treatment), or amiodarone (for heart disease treatment). Nodolox increases the adverse effects of these medicines.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Pregnancy
Some data indicate that short-term use of nitrous oxide during pregnancy does not pose a greater risk of congenital malformations. In isolated cases, nitrous oxide may cause respiratory problems in newborns
Breastfeeding
It is not known if medicinal nitrous oxide is excreted in breast milk. It is not necessary to interrupt breastfeeding after a short period of administration.
Driving and using machines
Do not drive or operate tools or machines after receiving Nodolox, as this medicine may affect your reaction ability. Your doctor will tell you how long you should wait before driving or using machines again.
3. How to use Nodolox
Nodolox will always be administered in the presence of personnel familiar with this type of medicine. The personnel will ensure that Nodolox can be used and that the equipment is installed correctly. While you are using this medicine, you will be supervised to ensure that it is administered safely. After finishing treatment with Nodolox, you will be monitored by competent personnel until you have recovered.
Always use this medicine exactly as your doctor has told you. The doctor should explain how to use Nodolox, how Nodolox works, and what effects result from its use. If you are in doubt, consult your doctor again.
Nodolox is usually inhaled through a facial mask connected to a special valve, which means you have full control over the gas flow through your own breathing. The valve is only open during inhalation. Nodolox can also be administered with a nasal mask.
Regardless of the mask you use, you should breathe normally through normal breaths with the mask.
After finishing treatment with this medicine, you should rest and recover until you feel you have mentally recovered.
Safety precautions
- It is strictly forbidden to smoke and be exposed to flames in the rooms where treatment with Nodolox is carried out.
- Nodolox is intended only for medical use.
If you use more Nodolox than you should
It is very unlikely that you will receive an excess of gas, as you regulate the gas supply and the gas mixture is fixed (contains 50% nitrous oxide and 50% oxygen).
If you breathe faster than normal and therefore receive more nitrous oxide than with normal breathing, you may feel clearly tired and notice that you have disconnected from your environment to some extent. In such a case, you should immediately inform the medical personnel and interrupt administration.
If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Common(may affect up to 1 in 10 people): Dizziness, mild dizziness, euphoria, nausea, and vomiting.
Uncommon(may affect up to 1 in 100 people): Severe fatigue. Feeling of pressure in the middle ear, if you use Nodolox for a prolonged period.
This is because Nodolox increases the pressure in the middle ear.
Abdominal swelling, due to Nodolox slowly increasing the volume of gas in the intestines.
Frequency not known(cannot be estimated from the available data): Effects on the bone marrow, which can cause anemia.
Effects on nerve function, sensations of numbness and weakness, usually in the legs.
This is because nitrous oxide affects the metabolism of vitamin B12 and folate, and thus inhibits an enzyme: methionine synthase.
Respiratory depression. You may also experience headache. Psychiatric effects, such as psychosis, confusion, anxiety, addiction.
Generalized convulsions with unknown frequency.

Safety instructions
Special precautions should be taken when working with nitrous oxide. Nitrous oxide should be administered according to local guidelines.
Repeated administration or exposure to nitrous oxide may lead to addiction. Healthcare professionals with occupational exposure to nitrous oxide should be cautious.
Nodolox should only be used in well-ventilated areas and where there is special equipment to extract excess gas. If an extraction system is used and good ventilation is ensured, high atmospheric concentrations of laughing gas in the air can be avoided. There are national guidelines for the concentration of laughing gas that should not be exceeded in the ambient air, often expressed as TWA (time-weighted average), the average value of a working day, and the STEL (short-term exposure limit) value during shorter exposure.
These values should not be exceeded to ensure that personnel are not exposed to risks.
- The valve should be opened slowly and carefully.
- Close the equipment in case of fire or if it is not in use.
- During use, the cartridge should be fixed in a suitable holder.
- Consider replacing the gas cartridge when the pressure in the cartridge has dropped to the point where the valve indicator is in the yellow field.
- When a small amount of gas remains in the cartridge, the valve should be closed.
- It is important to leave some pressure in the cartridge to avoid the entry of contaminants.
- After use, the valve of the cartridge should be manually closed until it is tight.
- Depressurize the regulator or connection.
