Antihistamines long term impact immune system?

Patient: Hi there,I take antihistamines (loratadine) all year to combat not only hayfever, but other allergies such as dust and cleaning products. Could this have a negative impact on my immune system? In the last few months I’ve had a number of infections – a gum infection, a severe ear infection and three recurring urine infections. I’ve taken antibiotics for all of these which I know creates its own problem. Could antihistamines be an underlying issue?Thanks,Becca
