Storing Pet Medications Safely at Home

Whether your pet takes a daily tablet, a flavoured chew, or a compounded liquid, safe storage is part of their care. A good storage routine helps protect the medication and prevents curious pets or children from getting into it.

Here are a few simple habits to follow at home.

Follow the Storage Instructions on the Label

Different medications have different storage requirements. Always follow the instructions on the dispensing label rather than assuming every product belongs in the same cupboard—or in the refrigerator.

For medications labelled for room-temperature storage, choose a dry location away from direct sunlight and heat. Avoid humid bathrooms, windowsills, and parked cars, where conditions can change quickly.

If the instructions are unclear, ask your pharmacist before choosing a storage spot.

Refrigerate Only When Directed

Some medications require refrigeration; others do not. Putting a medication in the refrigerator does not automatically make it last longer.

For refrigerated products, follow the temperature range on the label and protect the medication from freezing. Ask your pharmacist where to place it and how to transport it safely.

If a medication has been left out, frozen, or exposed to excessive heat, contact the dispensing pharmacy before using it again. Have the medication name, approximate temperature, and length of exposure ready. Its appearance alone cannot confirm whether it is still suitable to use.

Keep Medications in Their Original Containers

Keep each medication in the container supplied by your pharmacy, with the label readable. This keeps your pet’s name, directions, and medication details together.

Avoid combining leftover tablets with a new supply or transferring liquids into another bottle without checking with your pharmacist. The supplied packaging may help protect the preparation and support accurate use.

Keep Flavoured Medication Secure

A medication that tastes appealing can make dosing easier—but it may also tempt your pet to eat the entire supply.

Store all medications in a secure cupboard or locked storage area that children and pets cannot access. A high countertop may not be enough for a climbing cat or determined dog, and child-resistant packaging is not necessarily pet-proof.

Keep human medications separate from pet medications. If several pets receive treatment, organize each pet’s supplies separately to reduce mix-ups.

Pay Attention to Expiry and Beyond-Use Dates

Check the label regularly, especially for products used only occasionally.

Compounded medications have a beyond-use date, which tells you when the preparation should no longer be used. Some products also have a shorter discard period after opening or mixing.

Follow the applicable date and storage instructions supplied by your pharmacy. Refrigeration does not extend that date unless your pharmacist specifically advises otherwise.

If the colour, smell, texture, or consistency changes unexpectedly, contact the pharmacy before giving another dose.

Dispose of Unused Medication Safely

Keep expired or unwanted medication secure until you can return it to a participating medication collection location. In Ontario, the medication return program accepts unused or expired medications for companion animals.

Avoid putting medication down the sink or toilet, or leaving it in household garbage where pets could find it. Ask your pharmacy how to prepare products for return.

Used needles and syringes with needles belong in an approved sharps container, separate from medication returns.

What If Your Pet Gets Into Medication?

If your pet may have swallowed extra medication, another pet’s prescription, or a human medicine, contact your veterinarian or an emergency animal hospital immediately. Do not wait for symptoms.

Keep the packaging available and be ready to explain what your pet may have taken, how much, and when.
