How much does Claritin cost?

What is the difference between Claritin and its generics?
Brand-name Claritin and its generic counterparts contain the same active ingredient, loratadine, in the same dosage [5]. The U.S. Food and Drug Administration (FDA) requires generic drugs to be bioequivalent to their brand-name counterparts, meaning they work the same way in the body and have the same effects [6]. Differences may exist in inactive ingredients, which can affect appearance or taste, but these do not impact the drug's effectiveness or safety [5].
Can Claritin be bought over-the-counter?
Yes, Claritin is available over-the-counter (OTC) in many countries, including the United States [1]. This accessibility allows consumers to purchase it without a prescription for the treatment of allergy symptoms.
What are the side effects of Claritin?
Common side effects of Claritin (loratadine) can include headache, drowsiness, fatigue, and dry mouth. Less common side effects may also occur [7].
