Patient leaflet - Munuza 300 mg/5 ml nebuliser solution
1. What Munuza is and what it is used for
Munuza contains a medicine called tobramycin. This is an aminoglycoside antibiotic.
Munuza is used in patients aged six years and older who have cystic fibrosis to treat chest infections caused by a bacteria called Pseudomonas aeruginosa.
Munuza fights the infection caused by Pseudomonas bacteria in your lungs, and helps to improve your breathing.
When you inhale Munuza, the antibiotic can get directly into your lungs to fight against the bacteria causing the infection. For the best results of this medicine, use it as this leaflet instructs you.
What is Pseudomonas aeruginosa?
This is a very common bacteria that infects nearly everyone with cystic fibrosis at some time during their lives. Some people do not get this infection until later on in their lives, while others get it very young.
This is one of the most damaging bacteria for people with cystic fibrosis. If the infection is not properly controlled, it will continue to damage your lungs causing further problems to your breathing.
Munuza kills the bacteria that cause infections in the lungs. The infection can be controlled successfully if the problem is tackled early.
2. What you need to know before you take Munuza
Do not use Munuza:
if you are allergic to tobramycin, any type of aminoglycoside antibiotic or any of the other ingredients of this medicine (listed in section 6).
If any of the above apply to you, do not take this medicine and talk to your doctor. If you think you may be allergic, ask your doctor for advice.
Warnings and precautions
Talk to your doctor or pharmacist before taking Munuza if you have ever had any of the following conditions:
- Hearing problems (including ringing in your ears and dizziness)
- Kidney problems
- Unusual difficulty in breathing with wheezing or coughing, chest tightness
- Blood in your sputum (the substance you cough up)
- Muscle weakness that lasts or becomes worse in time, symptoms mostly related to conditions such as myasthenia or Parkinson’s disease
If any of these apply to you, tell your doctor before you take Munuza.
If you or your maternal family members have a mitochondrial mutation disease (a genetic condition) or loss of hearing due to antibiotic medicines, you are advised to inform your doctor or pharmacist before you take this medicine; certain mitochondrial mutations may increase your risk of hearing loss with this product. Your doctor may recommend genetic testing before administration of Munuza.
Inhaling medicines can cause chest tightness and wheezing and this can happen with Munuza. Your doctor will supervise your first dose of Munuza and check your lung function before and after dosing. If you are not already doing so, your doctor may ask you to use a bronchodilator, (e.g. salbutamol), before taking Munuza.
If you are taking Munuza, strains of Pseudomonas can become resistant to the treatment over time. This can mean the medicine may not work as well as it should over time. Talk to your doctor if you are concerned about this.
If you have it by an injection, tobramycin can sometimes cause hearing loss, dizziness and kidney damage, and can harm an unborn child.
Children and adolescents
Munuza can be taken by children and adolescents aged 6 years and older. It should not be given to children less than 6 years old.
Elderly
If you are aged 65 years and older, your doctor may perform additional tests to decide if Munuza is right for you.
Other medicines and Munuza
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
You should not take the following medicines while you are taking Munuza:
- Furosemide or ethacrynic acid, diuretics (“water tablets”)
- Urea or intravenous mannitol
- Other medicines which may harm your nervous system, kidneys or hearing.
The following medicines can increase the chances of harmful effects occurring if they are given to you while you are receiving injections of tobramycin:
- Amphotericin B, cefalotin, ciclosporin, tacrolimus, polymyxins: these medicines may harm your kidneys.
- Platinum compounds (such as carboplatin and cisplatin): these medicines may harm your kidneys or hearing.
- Anticholinesterases (such as neostigmine and pyridostigmine), or botulinum toxin: these medicines may cause muscle weakness to appear or become worse.
If you are taking one or more of the above medicines, discuss with your doctor before you take Munuza.
You should not mix or dilute Munuza with any other medicine in your nebuliser.
If you are taking several different treatments for cystic fibrosis, you should take them in the following order:
- 1. Bronchodilator therapy, such as salbutamol
- 2. Chest physiotherapy
- 3. Other inhaled medicines
- 4. Then Munuza
Please check this order with your doctor as well.

Use of Munuza with LC PLUS (PARI GmbH)
For more detailed instructions on the use and care of the nebuliser, please read the leaflet provided with the PARI LC PLUS.
- 1. Remove the nebuliser top from the nebuliser bottom by twisting the top anticlockwise and then lifting it. Place the top on the towel and stand the nebuliser bottom upright on the towel.

- 7. Place the mouthpiece between your teeth and on top of your tongue. Breathe normally, but only through your mouth (you may use a nose clip if your doctor agrees). Try not to block the airflow with your tongue.
- 8. Continue until all of the Munuza is gone and there is no longer any mist being produced. It should take about 15 minutes to take all the treatment. You may hear a spluttering sound when the nebuliser cup is empty.
- 9. Please remember to clean and disinfect your nebuliser after treatment according to the manufacturer’s instructions. You should never use a dirty or clogged nebuliser. You should not share your nebuliser with other people.
If you are interrupted, or need to cough or rest during your treatment, turn off the compressor to save your medicine.
