Headache/Facial pain. Were you taking Claritin (loratadine) specifically for the headache symptoms you are describing? Claritin (loratadine) is not indicated for headaches. If you have a history of environmental allergies that you are taking Claritin (loratadine) for, do continue to take it. Try an NSAID like advil, ibuprofen, Excedrin for headache. If it does help or you think this is different from your typical headache, go see you doctor asap.
Clarify? Are you taking Claritin (loratadine) for the headache? It can cause high blood pressure and therefore headaches. What is your question exactly?
