Why is one pill dangerous?
ADHD medicines contain amphetamines (Adderall, Vyvanse) or methylphenidate (Ritalin, Concerta). Dogs absorb them fast and their bodies cannot handle stimulants meant for a child’s weight.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of adhd-meds poisoning
- Hyperactivity, restlessness, pacing
- Rapid heart rate and breathing
- Dilated pupils, drooling, panting
- Tremors, seizures
- Very high body temperature — life-threatening
What to do right now
- Call your vet immediately. Stimulant poisoning escalates fast.
- Bring the pill bottle — extended-release versions keep releasing for hours.
- Do not try to "run it off"; keep the dog quiet.
- Hospital treatment (sedation, cooling, IV fluids) greatly improves survival.
