What is a common side effect of Claritin?

Claritin, which is the brand name for loratadine, is an antihistamine commonly used to relieve allergy symptoms. While it is generally known for having a favorable side effect profile, headaches can occur in some individuals. This is likely due to the way antihistamines can affect the central nervous system, leading to symptoms such as headaches in certain patients.

Other side effects that may be associated with Claritin generally include mild sedation or fatigue, but headaches specifically stand out as a relatively common occurrence among users. Understanding this side effect is important for medication aides as they monitor patients for adverse reactions to medications like Claritin. In contrast, the other choices represent less common or atypical side effects associated with the drug, making headache the most appropriate answer in this context.
