A member asked:

I have noticed that my body is immune to loratadine based antihistamines (doesn't make me tired) but any others do. does this means tolerance?

Non-sedating: Loratadine is considered a non-sedating antihistamine. It is supposed to treat allergic symptoms without making you drowsy. Other older antihistamines like benadryl (diphenhydramine) are very sedating.
