I am allergic to dust, which causes me to have a runny throat all year round. Some over-the-counter antihistamines help a little (e.g. Reactin but Claritin and Aerius have no effect). Are there any other alternatives?
For the last 3 months, I have been blowing my nose and sneezing morning and night. I cough a little when lying down. Should I take any particular medication?
