Which of the following medications should be dispensed and stored in the manufacturers original container?

Duloxetine delayed-release capsules do not require storage in the manufacturer's original container for protection against light or moisture. While it is good practice to keep medications in their original containers for identification and safety, duloxetine is stable enough to be stored in alternative, appropriate containers.

Calcium carbonate chewable tablets are generally stable and do not have specific storage requirements that necessitate the use of the original container. These tablets can be stored in a cool, dry place without significant loss of potency or effectiveness, making them less critical in terms of container preservation.

Hyoscyamine oral disintegrating tablets also do not have strict requirements for being stored in the original container. While it’s advisable to keep medications in their original packaging for safety and convenience, the stability of hyoscyamine is not as jeopardized by exposure to light or moisture compared to nitroglycerin.
