5. Slowly squeeze about 4 ounces of solution into your right nostril. As you're doing that, try to breathe normally through your mouth. After a few seconds, you'll start to feel the solution flowing out through your left nostril.

6. Repeat these steps with your left nostril, but tilt your head down and rotate it to the right.

You may need to adjust your head position slightly to keep the solution from running down the back of your throat or into your ears. Also, blowing your nose gently will keep the solution from going into your ear.

Are There Any Side Effects or Precautions?

Saline is found naturally in the body, so this is considered a fairly harmless therapy. However, it should not be used if you have a sinus infection. Infections require treatment by a physician.

Also, it would be rare, but if notice any bleeding or pain, you should stop the saline rinse and call your doctor for advice.

Finally, don't stop taking your allergy medication unless you are sure that the saline irrigation is completely controlling your symptoms.
