Get Hypertonic Saline Online

Hypertonic saline is a sterile saltwater solution with a higher sodium chloride concentration than normal saline. When inhaled through a nebulizer, it draws water into the surface of your airways by osmosis. This thins and loosens thick mucus, making it easier to cough out or clear with airway clearance techniques.

The two most commonly prescribed concentrations are 3% and 7% sodium chloride. The 7% concentration is approved by the FDA specifically for cystic fibrosis. Your physician will choose the appropriate concentration based on your diagnosis, lung function, and tolerance.

Many physicians recommend inhaling a short-acting bronchodilator such as albuterol about 15 to 30 minutes before using hypertonic saline. This helps open the airways and reduces the risk of bronchospasm, which is a temporary tightening of the airways that some patients experience with hypertonic saline.

Patients with asthma or reactive airway disease require careful evaluation before using hypertonic saline because it can trigger bronchospasm. A physician will review your respiratory history and lung function, and may recommend a pre-treatment bronchodilator or a lower concentration to minimize this risk.

The typical prescribed regimen for cystic fibrosis is twice daily inhalation, often in conjunction with a formal airway clearance technique such as chest physiotherapy or an oscillating positive expiratory pressure device. Your physician will tailor the frequency to your specific condition and response to treatment.

The most common side effects include cough, throat irritation, a salty taste, chest tightness, and temporary bronchospasm. These are usually mild and often improve over time or with pre-treatment bronchodilator use. You should contact your provider if you notice significant wheezing, shortness of breath, or chest pain after inhalation.
