Hello My daughter has had a cough for 3 weeks now. It started with a sinus infection. That seems to have gone away. The cough caused by tickle in the throat keeps her coughing all day and sometimes in the middle of the night. She had a prescription of antibiotics, and flonase. The antibiotics have been done for a week now. She uses and albuterol inhaler as needed and takes a claritin 24 hr allergy daily. She takes a benadryl at night. SHe won t stop coughing, 3 in a row, every other minuteā¦all day. Sometimes worse. She says tickle in her base of throat. She takes Delsum, but it doesn t seem to affect her. This happened 2 years ago, and they were looking into allergies, then antibiotics, then back to allergies before it kind of just went away. Well, here we go again, how do we stop this dry raspy constant cough. She is 11 and 100 lbs. She takes focalin xr 20 mg for adhd during the school week. Thanks!
