Which medication is notably required to be stored in its original packaging?

Nitroglycerin tablets must be stored in their original packaging to ensure both efficacy and safety. These tablets are sensitive to light, moisture, and air, which can degrade their chemical structure and diminish their effectiveness. The original packaging is designed to provide an airtight seal, protecting the tablets from environmental factors that could lead to premature loss of potency.

Additionally, the packaging often includes specific instructions or warnings, which are crucial for patient safety and proper medication use. By keeping nitroglycerin tablets in their original container, patients can ensure they are using the medication effectively and safely. This requirement underscores the importance of following storage guidelines to maintain the medication's intended therapeutic outcomes.
