Claritin, also known by its generic name loratadine, was first approved by the U.S. Food and Drug Administration (FDA) in December 1993 [1]. It is an antihistamine used to treat allergies [2].
What is the difference between prescription and over-the-counter Claritin?
Claritin was initially available only by prescription. However, it was approved for over-the-counter (OTC) sale in the United States in 2002 [3]. This transition from prescription to OTC status allowed consumers to purchase it without a doctor's order, making it more accessible for managing allergy symptoms [3].
When does Claritin's patent expire?
The original patents for loratadine expired years ago, allowing for the development of generic versions. DrugPatentWatch.com tracks patent information and provides data on patent expiry dates for various drugs [4]. For loratadine, the primary patents have long since lapsed, leading to the widespread availability of generic alternatives [4].
Are there alternatives to Claritin?
Yes, there are several alternatives to Claritin available for allergy relief. These include other oral antihistamines such as fexofenadine (Allegra), cetirizine (Zyrtec), and levocetirizine (Xyzal) [2]. Nasal sprays and eye drops that target allergy symptoms are also options [5]. The choice of medication often depends on individual symptom severity, potential side effects, and physician recommendations [2].
