Antibiotics are used in CF to reduce the bacteria load (the number of bacteria) that are in your lungs. This will help to improve your lung function and reduce the damage to your lungs.

There are three ways of taking antibiotics:

1) Inhaled or nebulized.

2) Intravenous (IV) or in the vein.

3) Oral or by mouth.

Allergic reactions to antibiotics are more common in individuals with CF due to higher doses and longer durations of treatment with antibiotics. If you are allergic to an antibiotic that your doctor decides is necessary for your care, then you may be able to be desensitized to the antibiotic.
