How Claritin worksClaritin works similarly to Zyrtec, Dr. Alan says, meaning it helps block the effects of symptom-inducing histamine on the body. It’s recommended that adults and children aged six and up take a 10 milligram tablet once a day or two five-milligram tablets twice daily to relieve symptoms of allergies. But there are some differences between Claritin and Zyrtec: Claritin doesn’t cross the blood-brain barrier, so it’s unlikely to make you drowsy, she says. It also takes a bit longer to kick in, research shows: The effects of Claritin can be felt anywhere from one to three hours after you take it, reaching peak concentration in your body between eight and 12 hours after you take it. But it does work for many people. A 2018 randomized, double-blind study on loratadine found that people who took the medication two hours after being exposed to ragweed pollen had “significant and durable improvement” in their symptoms compared to those who took a placebo.
