Treatment

Medications
Antibiotics. These drugs are used to treat and prevent lung infections. They may be swallowed in pill form, inhaled in a mist or delivered intravenously.
Mucus-thinning drugs. Drugs that reduce the stickiness of your mucus make it easier to cough up the mucus, which improves lung function.
Bronchodilators. Medications such as albuterol — delivered by an inhaler or a nebulizer — help keep your airways open by relaxing the muscles around your bronchial tubes.
Therapy
People with cystic fibrosis need a way to physically remove thick mucus from their lungs. This is often done by manually clapping with cupped hands on the front and back of the chest — a procedure that's best performed with the person's head over the edge of the bed so that gravity helps clear the secretions.
