Cough drops may decrease some coughs but in general do not treat the underlying causes of a cough, so they won't "cure" your cough. You can try taking cough drops for a day to see if they help. If they work, then use them as needed. If they do not help, then don't waste your money. Cough drops always pose the risk of choking hazard, even in adults, and so do not go to sleep with a cough drop in your mouth or use them if you have any problems with swallowing.
