Nasal Spray
Nasal Saline Instructions

The function of the nose is to warm, filter, and humidify the air that is inhaled. Nasal saline helps to improve these functions, maximize the effect of other sprays, and to cleanse the nose. Improvement of nasal function helps to treat allergies, chronic sinus disease, and nosebleeds. Saline has no side effects, but can be distasteful to some people. It is best used in a preventive fashion, similar to tooth brushing.

Where do I get saline?

Saline can be made at home by adding ½ teaspoon of non-iodized salt to a cup of warm tap water. Non-iodized salt may be preferred because it burns less than regular salt. Tap water is usually acceptable, but after surgery, sterile saline may be recommended initially. This can be purchased at the pharmacy. If the water supply is questionable, the water may be boiled first and then allowed to cool prior to use.

Saline solutions can be purchased in prepackaged bottles at the pharmacy. Some of these preparations contain preservatives (e.g. benzyl alcohol), which can cause a burning sensation. Other solutions such as "Ayr" may be used in these cases.

How do I use saline?

Saline can be used as many times a day as needed, but usually 3 times a day is initially sufficient. Saline must often be used for at least 2-3 weeks every day to notice a difference in symptoms.

With premade solutions, a generous squirt in each nostril with a "sniff" is adequate. Homemade solutions can be placed in an empty squeeze bottle or into a "bulb" syringe that can be found at the pharmacy. When more vigorous cleansing is needed, a Water Pic type machine may be needed. An extension tip can be purchased to direct the water into the nose. The intensity can be adjusted so the saline flows out about three inches beyond the tip. The tip is placed just inside the nostril with the stream directed upwards and backwards.

Saline may be used prior to the use of steroid nose sprays (Flonase, Nasonex, Rhinocort) to help counteract the dryness that these medications often cause. Also, saline is helpful to keep the nose moist to help prevent nosebleeds.

Remember, these are general guidelines. If the nurse or physician gives you specific instructions those should be followed. Call (972) 402-8404 if you have questions.
