for sudden onset
This is a great product - esp for kids that start coughing in the middle of the night. every 15 mins for a max of 6. We have 4 little boys and have only had to use 6 doses once. usually stops after 2nd to 3rd dose. Use along with cough med or A.G.E for sudden onset of a cold. These products aren't so effective if antibiotics have been used recently.
