- Acetaminophen: Tylenol - Causes liver damage, red blood cell damage in cats
- Antidepressants: Can cause serotonin syndrome
- ADHD medications: Stimulants cause tremors, seizures, hyperthermia
Symptoms of Medication Poisoning
- Vomiting, diarrhea (often with blood)

Prevention Tip
Store all medications in secure cabinets, not on nightstands or countertops. Never give human medication to pets without explicit veterinary instruction. Use child-proof containers, but remember they're not pet-proof.
