The recommended instructions for using Prevalin Allergy is one to two sprays in each nostril two to three times a day. You should blow your nose thoroughly before each application. Shake well before using the spray. Only use the spray in the nose and do not swallow the spray.

The spray can also be used safely if you are pregnant or breast-feeding, but again, speak to your doctor or pharmacist before doing so.
