Effectiveness
How Azelastine Hydrochloride Affects PatientsAzelastine works by blocking the effects of histamine, providing relief from allergy symptoms. When taken in nasal or eye drop form, it will start working within 15 minutes and last for up to 12 hours. The peak effects usually occur 4-6 hours after taking the initial dose.
How Azelastine Hydrochloride works in the bodyAzelastine works by blocking histamine H1-receptors, which are found on nerve endings, smooth muscle cells, and glandular cells. When allergens are present in sensitized individuals, histamine is released and binds to these receptors. This contributes to allergy symptoms like itching, sneezing, and congestion. Azelastine also helps to stabilize mast cells, prevent the release of other inflammation-causing substances, and reduce substances that cause nasal itching and sneezing.

Azelastine Hydrochloride Reviews: What are patients saying about Azelastine Hydrochloride?
5Patient Review
2/18/2022 I can't believe how well this nasal spray worked for me! I'm 60 years old and have suffered from allergies my whole life, but this is the best medication I've ever used.
5Patient Review
3/5/2022 Almost immediate results if you follow the directions. To those complaining about the taste, read the label!
5Patient Review
4/8/2022 After taking the second dose, I felt a bit chilly.
4.3Patient Review
3/30/2022 I found this to work well for sinus and ocular pressure. It dried out my sinuses and helped thin the mucus so that it could pass more easily. I liked it for seasonal use in teens. It also worked well in combination with antibiotics for ear or sinus infections.The drawbacks are the foul taste and burning, but for me it works better than flonase. I don't really feel tired, at most there's a small buzz and reduced reaction time.
4.3Patient Review
5/21/2022 I've found this to be an effective treatment for post-nasal drip and inflammation. My sinuses feel lighter and I'm sleeping better at night. The only downside is that during the day I sometimes find it hard to move because of the lethargy, but overall I'm grateful for a product that actually works.
