Before Using This Medicine

Pregnancy—Azelastine has not been studied in pregnant women. However, studies in animals have found that azelastine, given in high doses, causes harmful effects on the fetus. Before taking this medicine, make sure your doctor knows if you are pregnant or if you may become pregnant.

Mothers who are taking this medicine and who wish to breast-feed should discuss this with their doctor.

Children—Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of azelastine in children under the age of 3 years with use in other age groups.

Tell your health care professional if you are using any other prescription or nonprescription (over-the-counter [OTC]) medicine.
