How to Use

Take 1 tablet by mouth every night before bed. May be taken with or without food.

Common Side Effects

Sleepiness, fatigue, nasal irritation, dry mouth, and sore throat.

Levocetirizine was designed to be less sedative than Zyrtec, but it may still cause sleepiness in some users, so we recommend taking it at night.

Transparent Manufacturing

Levocetirizine is manufactured in the USA.

Do NOT use levocetirizine while taking Allegra (fexofenadine), Claritin (loratadine), Zyrtec (cetirizine), or other oral antihistamines.

If taking one of those medications, talk to your Ro-affiliated doctor about discontinuing use prior to taking levocetirizine.

Allergy medication works best when taken every day.

Be sure to continue using your medication as directed, even after your symptoms have improved.

If you have any questions about your treatment, message your provider at any time.
