When it comes to keeping our beloved dogs and cats safe, most pet owners focus on food, plants, or household chemicals. However, one of the most overlooked dangers is human medications and supplements. What we consider life-saving or routine for ourselves can quickly become toxic—even fatal—for our pets.
At North Care Animal Hospital, we see many cases of accidental poisoning every year. From over-the-counter painkillers to prescription drugs left on the counter, the reality is clear: even small doses can be dangerous. In this article, we’ll explain the risks, provide practical tips, and show you how to act fast if an emergency happens.
Why Human Medications Are So Toxic to Pets
The human body metabolizes drugs differently than cats and dogs. For example:
Dogs may experience liver toxicity from drugs that humans process without issue.
Cats lack certain liver enzymes, making them especially vulnerable to even trace amounts of some medications.
Body weight differences mean a pill safe for a 70-kg adult could be deadly for a 5-kg cat.
Because of these biological differences, medications considered “harmless” for humans can trigger vomiting, seizures, organ failure, or worse in pets.
Common Medications That Poison Dogs & Cats
Here are the most frequently reported cases in veterinary hospitals across Canada, including North and West Vancouver:
| Medication / Supplement | Danger Level for Pets | Symptoms in Cats & Dogs |
|---|---|---|
| Acetaminophen (Tylenol) | Extremely toxic, especially to cats | Liver failure, difficulty breathing, swollen face/paws |
| Ibuprofen / Naproxen | Very toxic | Vomiting, stomach ulcers, kidney failure |
| Antidepressants (SSRIs, SNRIs) | Moderate to high toxicity | Lethargy, tremors, seizures, heart rhythm changes |
| Blood pressure medications (beta blockers, ACE inhibitors) | Toxic in moderate doses | Weakness, collapse, dangerously low blood pressure |
| ADHD medications (amphetamines) | Highly toxic | Hyperactivity, tremors, seizures, cardiac issues |
| Diabetes medications (insulin, sulfonylureas) | Severe hypoglycemia | Weakness, seizures, coma |
| Vitamins with iron or vitamin D | Very toxic | Vomiting, abdominal pain, organ damage |
| Herbal supplements (garlic, ginseng, tea tree oil) | Toxic depending on dose | Anemia, neurological issues, skin reactions |
Supplements: Natural Doesn’t Mean Safe
Many pet owners assume that if a supplement is “natural,” it must be safe. Unfortunately, that’s not true. Herbal remedies, protein powders, or even daily vitamins can be harmful.
Vitamin D toxicity can cause fatal kidney failure.
Iron supplements are caustic to a pet’s digestive system.
Essential oils (tea tree, peppermint, eucalyptus) can cause neurological problems in cats.
Always consult with your veterinarian before giving any supplement to your dog or cat.
Recognizing Symptoms of Medication Poisoning
Signs of poisoning can develop quickly—sometimes within 30 minutes. Common red flags include:
Sudden vomiting or diarrhea
Lethargy or hyperactivity
Shaking, tremors, or seizures
Pale gums or jaundice (yellow eyes/skin)
Difficulty breathing or collapse
If you notice any of these, do not wait. Call a veterinarian immediately.
What to Do If Your Pet Is Exposed
Stay calm – Panicking delays help.
Do not induce vomiting unless specifically instructed by a veterinarian. Some substances cause more harm coming back up.
Bring packaging or pill bottles – Knowing the exact medication and dosage helps the vet determine treatment.

Professional Treatment Options
At North Care Animal Hospital in North Vancouver and our West Vancouver Animal Hospital, we use advanced veterinary toxicology protocols:
Activated charcoal to bind toxins in the stomach.
IV fluids to protect the kidneys and flush the system.
Antidotes where applicable (e.g., Vitamin K for rodenticide).
Continuous monitoring for heart rate, blood pressure, and organ function.
We also offer Walk-In Vet Services so you don’t have to wait for an appointment when seconds matter.
Prevention Tips for Pet Owners
Store all medications in sealed cabinets, not purses, backpacks, or counters.
Never assume “pet versions” of human drugs are safe—consult a vet first.
Dispose of expired medications safely.
Educate family members, especially children, about the risks.
If you use supplements, keep bottles tightly closed and out of reach.
For extra peace of mind, our In-Home Veterinary Services provide mobile vet care across North & West Vancouver, making it easier for you to get advice and treatment right where you are.
