In my latest blog post, I discussed the impact of azelastine on the gastrointestinal system. Azelastine is an antihistamine commonly used to treat allergies, but it may also affect our digestive health. Some users have reported side effects like nausea, vomiting, and diarrhea. While these symptoms are generally mild and temporary, it's essential to consult with a healthcare professional if they persist. Overall, azelastine is a helpful medication for allergy sufferers, but it's crucial to be aware of its potential gastrointestinal side effects.
