Promixin contains the active ingredient colistimethate sodium, andis administered by inhalation to treatchronic respiratory infectionsin patients with cystic fibrosis. Promixin is used when such infections are causedby a specific type of bacteriacalledPseudomonas aeruginosa.

This is a very common type of bacteria that infects the lungs of almost all patients with cystic fibrosis at some point in their lives. If the infection is not controlled properly, it will continue to damage the lungs and cause further problems.

To administer Promixin, the powder contained in the vial must be dissolved with an appropriate dissolving solution, sterile saline solution, or sterile water, and thenaspirated (inhaled) into the lungs using an appropriate inhalation device, so that the majority of the antibiotic can target the bacteria causing the infection.

In certain circumstances, your doctor may decide not to prescribe Promixin for you.

Do not use Promixin:

• If you areallergic(hypersensitive) to colistimethate sodium,colistin, orother polymyxins;

If you are in this situation, inform your doctor before starting to take Promixin.

Warnings and precautions with Promixin and inform your doctor:

• If you have or have hadkidney problems;
• If you havemyasthenia gravis(a rare disease in which your muscles are extremely weak and tire quickly);
• If you haveporphyria(a rare metabolic disorder that some people are born with);
• If you haveasthma.

If you are in any of these situations, inform your doctor.

In premature infants and newborns, caution should be exercised when using Promixin because the kidneys are not yet fully developed.

Other medications and Promixin:

Inform your doctor or pharmacist if you are taking, have taken recently, or may take any other medication.These medications may interfere with the effects of Promixin.

• Medications that may affect how your kidneys function. Taking these medicationsat the same time asPromixin may increase the risk of kidney damage
• Medications that may affect your nervous system. Taking these medications at the same time as Promixin may increase the risk of adverse effects on your nervous system
• Medications called muscle relaxants,often used duringgeneral anesthesia.Promixin may increase the effects of these medications. If you are to receive general anesthesia, inform your anesthesiologist that you are using Promixin.

If you have myasthenia gravis and are also taking other antibiotics called macrolides (such as azithromycin, clarithromycin, or erythromycin), or antibiotics called fluoroquinolones (such as ofloxacin, norfloxacin, and ciprofloxacin), taking Promixin increases your risk of muscle weakness and respiratory difficulties even more.

Receiving colistimethate sodium as an infusion at the same time as receiving Promixin as an inhalation may increase your risk of adverse effects.

Promixin is inhaled from a device called a nebulizer. Promixin can be administered using any nebulization system that can be used to release antibiotics in the lungs in the form of a mist.In countries where the I-neb AAD system is available,Promixin is presented with a Promixin Disk that can be used with the I-neb AAD system.

How to prepare Promixin

Your doctor or nurse will show you how to prepare and use Promixin with the nebulizer.

Before placing Promixin in the nebulizer and inhaling it, you must first dissolve it withsterile water, sterile 0.9% saline solution, ora 1:1 mixture of sterile water and sterile 0.9% saline solutionas indicated below.Your doctor or nurse will indicate the correct volume of liquid to add to each vial of Promixin and how many vials of Promixin to use for each dose with your nebulizer.

1)Locate the tab on the red plastic cap near the arrow with the "FLIP UP" mark. Then, holding the vial with one hand and the plastic cap with the other,turn the cap a little counterclockwise.Place your thumb under the tab and push the cap up about 90° (see diagram 1).

2)Take the plastic cap as shown in the diagram 2 and pull it slowly, like a hinge, until almost 180°.

3)Turn the vial so that the plastic cap is facing you. Holding the cap by the center as shown,pull it down and turn it slightly to the right (diagram 3a) or to the left to break the metal seal only on one side (diagram 3b).

4)Once the seal is broken, hold the vial firmly and remove the metal seal to expose the entire rubber stopper (diagram 4).

5) Remove the rubber stopper from the Promixin vial by holding only the outer edge of the stopper and place it upside down on a clean surface. Add sterile water, sterile 0.9% saline solution, or a 1:1 mixture of sterile water and sterile 0.9% saline solution to the vial,until you reach the volume of liquid indicated by your doctor or nurse.

6)Put the rubber stopper back and turn the vial upside down carefully two times (diagram 6).

7)Roll the vial carefully between your hands to dissolve all the visible Promixin powder at the bottom and side of the vial (diagram 7). Do not shakethe vial too hard as this could cause the solution to foam.

8)When most of the powder has dissolved, leave the vial to rest for 5-10 minutes to allow any foam to disappear and for any remaining powder to dissolve.

Empty the solution into the nebulizer and inhale immediately.If it is not possible to use the solution immediately, reseal the vial and store it in the refrigerator for a maximum of 24 hours.Do not use any solution that has been prepared for more than 24 hours.See section 5 "Storage of Promixin" for instructions on how to store or dispose of any unused Promixin.
