Claritin: What It Is, How It Works, and What You Need to Know
When you’re sneezing, itchy, or fighting runny eyes from pollen or dust, Claritin, a non-drowsy antihistamine used to treat allergy symptoms like runny nose, itchy eyes, and hives. Also known as loratadine, it works by blocking histamine—the chemical your body releases during an allergic reaction. Unlike older antihistamines like Benadryl, Claritin doesn’t usually make you sleepy, which is why so many people reach for it during allergy season or when dealing with year-round triggers.
Claritin is part of a larger group called antihistamines, medications that block histamine receptors to reduce allergy symptoms. But not all antihistamines are the same. Some, like Zyrtec or Allegra, work similarly but may have different side effect profiles. Claritin stands out because it’s available over-the-counter, lasts up to 24 hours, and is safe for most adults and kids over two. But here’s something many don’t realize: even though Claritin is labeled "non-drowsy," it can still cause drowsiness in some people—especially when mixed with alcohol, a central nervous system depressant that multiplies sedative effects. Studies show combining the two increases dizziness, slowed reaction time, and even risk of accidents. That’s why doctors warn against drinking while taking Claritin, even if you feel fine.
Claritin doesn’t cure allergies—it just manages symptoms. It won’t help with asthma flare-ups or severe reactions like anaphylaxis. For those, you need epinephrine or other emergency treatments. But for everyday stuff like hay fever, pet dander, or mold, Claritin is one of the most reliable tools you can use. And because it’s generic and widely available, it’s often the first choice for families looking for affordable, daily allergy control. Still, people often wonder: is it safe long-term? Can kids take it? What if you have liver problems? The posts below answer these questions with real-world advice, from how to handle missed doses to why some people still feel tired even on Claritin.
What you’ll find here isn’t just marketing hype. These are real stories and science-backed tips from people who’ve lived with allergies, doctors who’ve seen the side effects, and pharmacists who’ve tracked what works—and what doesn’t. Whether you’re new to Claritin or have been using it for years, there’s something here that’ll make your next allergy season easier.
