Cetirizine patent expiry date in us fda orange book?

See the DrugPatentWatch profile for Cetirizine

I can look up the exact FDA Orange Book “patent expiry” date for cetirizine in the US, but I need one detail first because Orange Book listings are by specific product(s) and applicant(s) (there may be multiple NDCs/label versions and different patents).

Which cetirizine product do you mean?
Please reply with one of the following:

  1. The dosage form/strength (e.g., cetirizine HCl 10 mg tablet, 5 mg/5 mL syrup, etc.), or
  2. An NDC number, or
  3. The brand name (e.g., Zyrtec or another label you’re looking at) and (if known) the applicant/holder.

Once you share that, I’ll tell you the Orange Book-listed patent numbers and the listed expiry dates for that product (and whether they’re expiration dates vs. pediatric/other exclusivities).
