Azelastine is used to relieve nasal symptoms such as runny/itching/stuffy nose, sneezing, and post-nasal drip caused by seasonal allergies, or other allergic or non-allergic conditions. This medication is an antihistamine. It works by blocking certain natural substances called histamines that are responsible for allergic symptoms.
Read the Patient Information Leaflet provided by your pharmacist before you start using azelastine and each time you get a refill. Follow the instructions on how to properly use this medication. If you have any questions regarding the information, consult your doctor or pharmacist.
Follow the instructions for properly priming the spray pump before using the bottle for the first time and if you have not used the medication for 3 or more days. Avoid spraying in your eyes or mouth.
Azelastine is for use in your nose and is available in different strengths. Use 1 or 2 sprays in both nostrils, usually once or twice a day as directed by your doctor. The dosage is based on your condition, the product you are using, and your response to treatment.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time(s) each day. This medicine usually begins working within 3 hours of use.
Inform your doctor if your symptoms do not improve.
A bitter taste in the mouth, drowsiness, a burning feeling inside the nose, sneezing fits, nose bleeds, runny nose, nausea, dry mouth, headache, weight gain, muscle aches, and red eyes may occur. Strange feelings on the skin (e.g., pins and needles, crawling sensation) may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
The bitter taste can be reduced by sniffing gently through your nose after each spray, rather than breathing in through your nose so deeply that the medication goes to the back of your throat and gets into your mouth.
