Yes, my daughter does both, well actually they both use both of them...Jordin's HTS is just diluted a little to make 3%. They each do the HTS twice a day and Pulmozyme once. When sick they do Pulmozyme twice each day. Ashlee just recently started HTS, but it makes her cough alot (she has been sick)...so it seems it does alot of good. She has never coughed from the Pulmozyme.
I think this is very common to do.
