All drugs have side effects, depends on the antihistamine as to what the important ones are.

First generation antihistamines are the ones that cross the blood brain barrier therefore causing the most drowsiness.

Loratadine is from the second gen, it's not supposed to cause drowsiness, but it's known to do that in some patient population.

Alright, in some people, because the pharmacist told me not to take them a lot since they can have side effects.
