Frequently Asked Questions
How is Levocetirizine different from Cetirizine?
Levocetirizine is the active isomer of Cetirizine. It binds more strongly to histamine receptors, allowing it to work effectively at half the dose (5mg vs 10mg) with potentially fewer side effects.
Can I take Levocetirizine daily?
Yes, it is commonly taken daily during allergy seasons, but it should be discontinued once symptoms resolve.
