Does Claritin Make You Drowsy?

No, Claritin (loratadine) is classified as a non-drowsy antihistamine and rarely causes sedation. Unlike first-generation antihistamines such as Benadryl, Claritin doesn't easily cross the blood-brain barrier, which significantly reduces drowsiness risk. Clinical studies show that only 2-3% of patients experience mild fatigue with Claritin, compared to 25-30% with older antihistamines. The drowsiness rate is similar to placebo in most trials. However, individual responses can vary, and some people may still feel slightly tired, especially when first starting the medication or when combined with other substances that affect alertness.
