Who makes claritin?

Claritin (loratadine) is a brand‑name drug that is manufactured and marketed by Bayer AG, the German pharmaceutical company. In the United States the product is sold under the Bayer HealthCare brand.

If you’re looking for the generic version, it’s available from a number of manufacturers (e.g., Teva, Sandoz, Mylan, etc.), but the original Claritin you’ll find in drugstores is a Bayer product.
