Loratadine Dosage: What You Need to Know About Safe Use and Alternatives

When you reach for loratadine, a non-drowsy antihistamine used to treat allergies like hay fever and hives. Also known as Claritin, it's one of the most common over-the-counter meds for sneezing, runny nose, and itchy eyes. But knowing the right loratadine dosage isn’t just about following the bottle—it’s about matching it to your age, health, and symptoms.

Most adults take 10 mg once a day. That’s it. No need to split doses or double up. Kids over 6 years old usually get the same dose, but younger kids need lower amounts based on weight. If you have liver problems, your doctor might cut that dose in half. Why? Because your body can’t clear the drug as fast, and too much builds up. This isn’t theory—it’s how the FDA and major health systems actually recommend using it.

Loratadine doesn’t make most people sleepy, but it’s not magic. If you’re still itchy after a week, or your nose won’t stop running, it might not be the right fit. Other antihistamines like cetirizine or fexofenadine work similarly but can hit differently for some people. And if you’re mixing it with other meds—like antibiotics or antifungals—that can change how loratadine behaves in your body. Always check with a pharmacist before combining.

There’s no one-size-fits-all when it comes to allergy relief. Some people need more than one pill a day. Others find that switching to a nasal spray or eye drop cuts down the pill burden. What works for your neighbor might not work for you. That’s why the best advice isn’t just about dosage numbers—it’s about understanding how your body reacts, what else you’re taking, and when it’s time to try something else.

Below, you’ll find real comparisons and user-tested insights on how loratadine stacks up against other allergy treatments, what side effects actually happen (and how often), and how to adjust safely if your symptoms change. No guesswork. Just what people have learned through trial, error, and doctor visits.
