Hello. I m sorry your daughter isn t feeling well. As you may know, Lorinase contains two different medications: Loratadine, which is a non-sedating antihistamine, is designed to reduce allergic symptoms. In rare patients, loratadine could cause paradoxical drowsiness, but the drowsiness shouldn t be incapacitating. Pseudoephedrine is a decongestant. It dries and reduces swelling in the mucous membranes of the nose. Common side effects include restlessness, insomnia and tremor. In other words, pseudoephedrine should wake you up, not put you to sleep. All things considered, your daughter is reacting strangely to her medication -- if this is, indeed, a reaction to the Lorinase. If her symptoms haven t improved, I suggest you take her to her doctor.
