Uses of Zelanex: - Sneezing and runny nose due to allergies Allergic rhinitis, vasomotor rhinitis. Known hypersensitivity to Zelanex or any of its components.

Nasal Anti-histamine preparations.

Azelastine, a derivative of phthalazine, exhibits histamine H1-receptor antagonist activity in isolated tissues, animal and human models. It was used as a racemic mixture with no difference in pharmacological activity observed between enantiomers in vitro studies. The major metabolite, desmethylazelastine, also has H1-receptor antagonist activity.

How to use Azelastine Hydrochloride: Use this medicine in the dose and duration as advised by your doctor. Check the label for directions before use. Insert the bottle tip into one nostril and close the other nostril. Direct the spray towards the sides of your nostril, away from the cartilage dividing the two sides of your nose. As you spray, breath gently and keep the head upright. Repeat the same process for the other nostrils. Administration: Prime with 4 sprays before initial use; if idle for 3 days, reprime with 2 sprays Adult Dose: Allergic Rhinitis: Adults: 2 sprays per nostril twice daily. Child Dose: Allergic Rhinitis: Children 5 years to 11 years of age: 1 spray into each nostril twice daily. Children >12 years: 2 sprays per nostril twice daily.

Use during pregnancy: The effects of azelastine during pregnancy have not been fully studied. If the potential benefit justifies the potential risk to the fetus, azelastine should be used during pregnancy. Use in nursing mothers: It is unknown whether azelastine is excreted in human milk. However, caution should be exercised when administering azelastine to nursing mothers.

Precaution: In clinical trials, the occurrence of somnolence has been reported in some patients taking Azelastine Hydrochloride Nasal Spray; due caution should therefore be exercised when driving a car or operating potentially dangerous machinery. Concurrent use of Azelastine Hydrochloride Nasal Spray with Alcohol or other CNS depressants should be avoided because additional reductions in alertness and additional impairment of CNS performance may occur. Lactation: Not known if excreted in breast milk; use caution

Keep out of reach of children. Store in a cool and dry place protected from light. Do not freeze.

Azelastine blocks histamine H1-receptor activity and inhibits release of inflammatory mediators from mast cells.

Pregnancy Limited data from postmarketing experience over decades of use in pregnant women have not identified any drug associated risks of miscarriage, birth defects, or other adverse maternal or fetal outcomes Animal data In animal reproduction studies, there was no evidence of fetal harm at oral doses approximately 5 times the clinical daily dose; oral administration to pregnant mice, rats, and rabbits, during the period of organogenesis, produced developmental toxicity that included structural abnormalities, decreased embryo-fetal survival, and decreased fetal body weights at doses 270 times and higher than maximum recommended human daily intranasal dose of 1.096 mg; relevance of these findings in animals to pregnant women considered questionable based upon high animal to human dose multiple Lactation There are no data on presence in human milk, effects on breastfed infant, or on milk production; breastfed infants should be monitored for signs of milk rejection during use by lactating women; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from underlying maternal condition
