Why some over-the-counter medicine bottles are stuffed with cotton?
* This precaution is simply to prevent rattling and possible breakage of pills during transport. Cotton is used as the stuffing substance because of absorbency. It keeps the medicine dry. However, Druggist recommend the taking out of the cotton once the bottle is opened for use since cotton can also absorb moisture from the environment. also, if the cotton for some reason gets wet while inside the bottle - this condition will lessen the effectiveness of the medicine inside the bottle
