If you are given Medikarb by inhalation, it will always be given with medicinal oxygen.

Medikarb is administered exclusively in hospitals or medical centers under the supervision of medical, pharmaceutical, or nursing staff. Make sure your healthcare professional is aware of any conditions you have.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before you start using Medikarb.

Be particularly careful with Medikarb

3. How to use Medikarb

Administration of Medikarb by inhalation in the form of a mixture with other medicinal gases is applied using a respiratory mask, a mouthpiece, or an endotracheal tube (which is inserted into the airways).

Special medical equipment will be used:

  • to inflate parts of your body during laparoscopic surgery or gynecological procedures,

If you use more Medikarb than you should

When this medicine is administered at concentrations above 5%, it can cause extreme difficulty breathing, increased blood pressure, nausea, vomiting, and occasionally loss of consciousness. In case of overdose, your doctor, pharmacist, or nurse will stop administration and provide appropriate care. Contact with the product can cause burns or frostbite.

If you have any questions, talk to your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Possible side effects are:

  • difficulty breathing, dry cough, increased blood pressure and heart rate, headache, tingling, alteration of taste, and nausea, if administered at a concentration below 5%;

5. Storage of Medikarb

Keep this medicine out of the sight and reach of children.

Do not use this medicine after the expiry date which is stated on the label after EXP. The expiry date is the last day of the month shown.

The gas cylinders should be stored:

  • at a temperature between -20°C and +65°C;
  • covered and protected from adverse weather conditions;
  • in a well-ventilated area, used exclusively for the storage of medicinal gases;
  • separated from gas cylinders containing other gases or different in composition;
  • protected from falls and other types of impact;
  • away from heat sources. The valves of the gas cylinders are equipped with a rupture disc to prevent the cylinder from cracking due to excessive pressure. The rupture disc may fail in case of excessive temperature. This would cause the release of the entire contents of the cylinder. In that case, do not enter the storage area and ventilate the area well until an expert certifies it is safe.

Empty gas cylinders should be stored separately. Return empty gas cylinders to the supplier.
