There are no adequate or well-controlled studies in pregnant women. Following intranasal administration of the maximal recommended clinical dose to patients, mometasone plasma concentrations are not measurable, thus fetal exposure is expected to be negligible and the potential for reproductive toxicity, very low. As with other nasal corticosteroid preparations, Axcel Mometasone 0.05% w/w Nasal Spray should be used in pregnant women, nursing mother or women of childbearing age only if the potential benefit justifies the potential risk to the mother, fetus or infant. Infants born of mothers who received corticosteroids during pregnancy should be observed carefully for hypoadrenalism.
