When preparing for emergencies or simply ensuring your medications remain effective for as long as possible, proper storage is important. This guide covers vacuum-sealing medications, temperature control, and how to store additional medical supplies to build a reliable and efficient medical kit.


Before I dig in, a common question is:

"how do you get these medications; don't you need a prescription?"

That's correct: many of the medications I stock are NOT over the counter (meaning: you need a Rx). You can order current meds and "in-case-of" medications online, I've written about that here: Personal Prescription Medication Supplies + coupon code to save $.

This process provides you with the ability to not waste your time and money visiting a gatekeeper and a pharmacy. You can order online and it's shipped to your door. + you get Rx cards that explain each medication sent and precautions, reasons to use, and dosing.

Vacuum-Sealing Medications for Longevity

Vacuum sealing medications, especially in their original containers, can protect them from environmental factors that degrade their quality.

Medication Long Term Storage

Why Vacuum Seal?

Protection Against MoistureVacuum sealing removes air and reduces humidity exposure, a major factor in medication degradation.
Barrier to ContaminantsAirtight sealing keeps out dust, pests, and other environmental contaminants.
Extended Shelf LifeVacuum-sealing, combined with cool and dark storage conditions, can help maintain the potency of medications.

What to Watch Out For:

Bottle CompressionSlight compression is fine as long as the pills inside remain intact, and the bottle's seal isn't broken.
Label VisibilityEnsure labels remain readable for proper identification and instructions.
Additional MeasuresA desiccant packet in the bag is optional. I skip it, but it makes sense in a humid climate.

How do I vacuum seal these medications?

Vacuum-sealing medications in their original containers can be a straightforward and effective process when done properly. Using a chamber vacuum sealer ensures a secure, airtight seal for long-term storage.

Step-by-Step Guide to Vacuum-Sealing Medications

  1. Gather Your Supplies:
    • Chamber vacuum sealer machine
    • Heavy-duty vacuum-sealer bags
    • Desiccant packets (optional, for extra moisture control if you're unsure of the moisture content when vacuum sealing - live in a humid climate)
    • Prescription medications in their original containers
  2. Inspect the Medication Containers:
    • Ensure the caps are securely tightened.
    • Check that the container seals (if present) are intact to avoid moisture or air leaks during sealing.
  3. Prepare the Vacuum-Sealer Bag:
    • Use the appropriate size bag, leaving a few extra inches for sealing.
    • If using desiccant packets, place one inside the bag with the medication container for added humidity protection. Note: I did NOT use desiccants.
  4. Load the Bag into the Chamber:
    • Place the medication container inside the vacuum-sealer bag and position it flat within the chamber.
    • Ensure the bag’s opening is properly aligned with the sealing bar.
  5. Set the Machine Parameters:
    • Adjust the vacuum pressure settings to prevent excessive compression.
    • Use a moderate vacuum level to avoid damaging the pill bottle or its contents.
  6. Seal the Bag:
    • Start the chamber vacuum sealer and let it remove the air and create a strong, airtight seal.
    • Double-check the seal for uniformity and strength after the process is complete.
  7. Label the Sealed Bag:
    • Clearly label the outside of the bag with the medication name, dosage, and expiration date for easy identification.

Why Use a Chamber Vacuum Sealer?

Better Air RemovalChamber vacuum sealers remove more air compared to external sealers, ensuring a tighter and more secure seal.
Gentle CompressionThese machines allow for fine-tuned settings to prevent over-compression, which could damage the medication containers.
Professional-Level SealChamber sealers create robust seals that are ideal for long-term storage.

Tips for Optimal Sealing Results:

Use Transparent BagsThis allows you to view the contents without opening the bag.
Store in a Cool, Dark PlaceEven vacuum-sealed medications require proper temperature control to maintain their potency.
Group Related ItemsFor organization, you can vacuum-seal medications in small batches, ensuring each bag has related items or similar expiration dates.

Temperature Control: A Critical Factor

Temperature plays a significant role in preserving the efficacy of medications.

What Does Temperature Control Look Like?

Ideal RangeMost medications should be stored between 68°F and 77°F (20°C to 25°C). Some can tolerate cooler temperatures but avoid freezing unless specified by the manufacturer.
Consistent EnvironmentStore medications in areas with stable temperatures, away from direct sunlight or fluctuating heat sources.
Emergency OptionsIf refrigeration is required and power is unreliable, consider investing in a portable battery-powered cooler.

Comprehensive Storage in a Milwaukee Packout Box

For organization and protection, I prefer the Milwaukee Packout box as it's a durable and practical solution. Here's what you can store in it:

1Prescription MedicationsVacuum-sealed in their original containers.
2Medical DevicesPulse oximeter, battery-powered blood pressure device, nebulizer, and stethoscope.
3Instruction GuidesInclude printed instructions for all medications and devices.
4Topical OintmentsStore separately in sealed bags to prevent leaks.
5Other SuppliesExtra batteries, a thermometer, alcohol wipes, and spare parts for devices.

Common Questions About Medication Storage

Can vacuum-sealing medication damage the pills?

Vacuum-sealing won’t damage pills as long as they’re stored in their original container. Avoid excessive compression that might crush fragile pills or blister packs.

How can I ensure labels remain readable?

Place the bottle inside a clear vacuum-sealed bag and include a note on the exact name on the outside of the bag at the top (easy to see when you're sorting through).

What happens if medications get too hot?

Excessive heat can degrade active ingredients, rendering the medication less effective or even harmful. Store in a cool, dark place.

Can topical ointments be vacuum-sealed?

Yes, but ensure they are in leak-proof containers to avoid messes. Use separate bags for ointments to prevent cross-contamination.

How often should I check stored medications?

Inspect your stored medications every 6-12 months for expiration dates, label integrity, and container condition.

How long do medications last past their expiration date?

The military's Shelf Life Extension Program found that 88% of 122 drugs stored under ideal conditions had their expiration dates extended, by an average of 66 months. Here's some information on medications past their expiration date:

Practical Steps for Storing Medications

1Organize SuppliesUse compartments in your Milwaukee Packout box for easy access and transport.
2Add Moisture ProtectionUse desiccant packets or silica gel inside vacuum-sealed bags if you live in a humid climate.
3Check TemperatureUse a thermometer to monitor storage conditions.
4Label ClearlyEnsure all items are properly labeled with expiration dates and usage instructions.
5Include InstructionsPlace printed guides for medications and devices.

Properly storing medications and medical supplies is essential for preparedness and emergencies. By vacuum-sealing pills, controlling temperature, and organizing items in a durable storage system, you can ensure your supplies are ready when you need them. A well-thought-out system, such as using a Milwaukee Packout box that's easy to grab and go, can make all the difference in safeguarding your health in uncertain times.

Questions this answers

Tap a question for the short answer.

Can I vacuum seal medications?

Yes. Vacuum seal medications in their original containers using a chamber vacuum sealer set to a moderate vacuum level. Sealing cuts exposure to moisture, dust, and pests, and combined with cool, dark storage it helps the medication hold its potency. Label each bag with the name, dosage, and expiration date.

How do I store medications long term?

Vacuum seal them in their original containers with caps tight and seals intact, then keep them in a cool, dark place between 68°F and 77°F with stable temperatures. Inspect them every 6 to 12 months. I organize mine with devices, instructions, and supplies in a Milwaukee Packout box.

Will vacuum sealing crush or damage pills?

Vacuum sealing does not damage pills as long as they stay in their original container. Use a moderate vacuum level and avoid excessive compression that could crush fragile pills or blister packs. Slight compression of the bottle is fine if the pills stay intact and the bottle seal is unbroken.

What temperature should medications be stored at?

Most medications should be stored between 68°F and 77°F, in a spot with stable temperatures away from direct sunlight and heat sources. Avoid freezing unless the manufacturer specifies it. Excess heat degrades active ingredients, and a portable battery-powered cooler is an option if refrigeration is required and power is unreliable.

How often should I check stored medications?

Inspect stored medications every 6 to 12 months. At each check, look at the expiration dates, confirm the labels are still readable, and examine the condition of the containers.

Should I put a desiccant in with vacuum sealed medication?

A desiccant packet is optional. It adds moisture control and makes the most sense if you live in a humid climate or are unsure of the moisture level when sealing. If you use one, place it in the bag beside the medication container. I did not use desiccants in mine.
