Sodium chloride inhalation is a sterile saline (salt water) solution that's breathed into the lungs using a nebulizer. It helps moisten the airways and loosen mucus so it's easier to cough up. The solution is often used for people with breathing conditions, such as cystic fibrosis. It's available in different strengths, including 0.9%, 3%, and 7%, and your dose depends on the product and why you're using it. Possible side effects include runny nose, cough, and restlessness.

What is Sodium chloride inhalation used for?

  • Thin and loosen thick mucus in the airways to make it easier to cough up

How Sodium chloride inhalation works

Sodium chloride inhalation is a mucolytic or mucus thinner. When inhaled through a nebulizer, it adds moisture to your airways. Higher-strength (hypertonic) saline also draws water into the airways, which helps thin and loosen thick mucus so it's easier to cough up.

Pharmacist tips for Sodium chloride inhalation

pharmacist
  • Sodium chloride inhalation can make you cough more because it loosens mucus in your airways. This is expected, especially if you're using it to clear mucus or produce a sputum sample.
  • Use each single-dose vial of sodium chloride inhalation right after you open it. Throw away any solution that's left because an opened vial can become contaminated.
  • Storage: Keep sodium chloride inhalation solution in its original vials at room temperature until you're ready to use it.

How to use sodium chloride inhalation:

  • Make sure you know how to use your nebulizer. Ask your care team or pharmacist to show you how if you're unsure.
  • Wash your hands with soap and water, then place your nebulizer on a flat surface and connect the parts.
  • Sit upright and turn on the nebulizer. Place the mouthpiece between your teeth and close your lips around it, or place the face mask securely over your face.
  • Take slow, deep breaths while inhaling the solution until no more mist comes out.
  • After treatment, clean your nebulizer as directed by the manufacturer. Let all the parts air-dry completely before storing them to help prevent germs from growing.
