There are many medications associated with the treatment of CF and they are each taken for specific purposes.Medications are sometimes used as preventatives, such as bronchodilators to open airways, or mucolytics to thin the mucus, making it easier to cough it out.

Other medications are for treatment of CF symptoms; such as pancreatic enzyme supplements to aid digestion, antibiotics to treat infections, and vitamin supplements to counteract malabsorption.

Medications come in many different forms, but it is most common for lung medications to be inhaled using a piece of equipment called a nebuliser which atomises the liquid medication into a very fine mist which can then be breathed directly deep into the lungs.

During periods when a patient is unwell, they may be required to have intravenous antibiotics. This means that they will require a hospital stay, but are often allowed to complete the medication at home.
