When medications aren’t stored properly, they can lose effectiveness, spoil, and cause health risks to patients. As a result, you need to understand which medications are stored in cold temperatures and vice versa. Here’s a list of the most common medications stored in freezers that you should know to ensure usefulness and safety.
Vaccines
First and foremost, vaccines must be stored in cold temperatures. That's why their proper storage and transport are so vital. Most vaccines have stringent temperature requirements. They require an unbroken cold chain, which means the temperatures can’t change. If they do, the vaccine will totally lose its effect. The yellow fever and COVID-19 vaccines require an unbroken cold chain. The Pfizer vaccine requires a cold chain of -70� C. The universal vaccine for mumps, rubella, and measles is also a cold chain drug. Vaccines need very careful handling and transportation to preserve their effects and ensure user safety.
Additional Note: Pfizer’s cold chain is exceptionally frigid, but it's the only way to preserve the vaccine's potency.
Insulin for Diabetes
Not every insulin type has to stay cold, but most have very stringent temperature requirements. If a form of insulin is sensitive to temperature, it must remain constant at all times. Even the tiniest fluctuations in temperature can cause adverse effects. For insulin, temperature change can cause it to become ineffective or even toxic. That's why properly storing and transporting insulin for diabetes is such a big deal. You can never expose insulin to heat levels over +8� C or colder than +2� C.
Eye Drops for Glaucoma
When caught early, glaucoma is highly treatable with eye drop medications. Yet, these drops have stringent temperature requirements. They're cold-chain drugs that patients must keep refrigerated at home. If these drops aren't refrigerated, they will become damaged and ineffective. That's why glaucoma patients have a hard time traveling. They must keep their eye drops refrigerated at temperatures between +2� C and +8� C.
Closing Thoughts
Those are the most common medications stored in freezers. By now, you should have a better understanding of cold-chain drugs. Vaccines, insulin, and glaucoma eye drops need to stay cold to stay effective. Failing to keep these drugs at proper temperatures can result in health hazards, so stay diligent.
A day to listen deeply, learn humbly, and honor the living wisdom of Native communities on Native Heritage Day on November 28th.
Opening Reflection
Native American Heritage Day is more than a mark on the calendar. It’s a living invitation to hear the first voices of this land, voices that carry stories of stewardship, innovation, courage, and care. As we step into this observance, we honor the people whose cultures, languages, and traditions continue to shape our shared future.
Artificial intelligence isn’t just a theory from science fiction anymore. It’s reshaping industries all over the world, and construction is right at the center of this shift. From automated machines on job sites to smart data analytics behind the scenes, AI's role in shaping the future of construction is about more than efficiency; it’s changing how people build, design, and manage structures. Instead of simple automation, we're seeing smarter, more responsive worksites that can adapt to challenges faster than ever.
Picture this: the sun dips below the horizon, casting a golden glow across your patio. Laughter fills the air as you grill steaks to perfection, a chilled drink in hand from your outdoor refrigerator.
Owning a car provides incredible freedom, but it also carries the responsibility of basic upkeep and preparation for unexpected events. You cannot predict every issue, but a curated kit turns a major headache into a minor inconvenience.
Thanksgiving on November 27th this year is more than a meal; it’s a stage for storytelling. Families are rediscovering the joy of sharing origin tales, funny mishaps, and heartfelt memories. Some hosts place a “story card” at each seat with prompts like “What tradition would you invent?” or “What are you most grateful for this year?” These sparks of conversation transform dinner into a living archive of family history. Recording or writing down these stories ensures they’ll be cherished for generations.
