Understanding Nazex 10 Tablet: How it Works
Nazex 10 Tablet contains 10mg of loratadine, an antihistaminic medication. It belongs to the class of second-generation antihistamines, which are known for causing less drowsiness compared to their first-generation counterparts. The body releases a chemical messenger called histamine during an allergic reaction, which causes symptoms like itching, swelling, and rashes. Loratadine works by blocking the effects of this histamine, preventing it from causing these unpleasant symptoms.
Unlike older antihistamines that can cross the blood-brain barrier and cause significant sedation, second-generation options like loratadine are more targeted. They primarily work on peripheral histamine receptors, resulting in a low risk of drowsiness while effectively controlling allergy symptoms. Nazex 10 Tablet is typically taken once daily, with effects lasting up to 24 hours.
Key Uses for Nazex 10
Nazex 10 Tablet is prescribed for a range of allergic conditions, providing symptomatic relief.

- Sneezing
