Why Organophosphates Are Hazardous
Organophosphates inhibit acetylcholinesterase, causing an overload of acetylcholine at nerve synapses. This leads to uncontrolled stimulation of muscles, glands and the heart.
The toxicity can appear within minutes after ingestion or skin contact, making prompt action essential.
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.
Signs to watch for
- Profuse drooling
- Excessive tearing
- Urination and defecation
- Vomiting and diarrhea
- Muscle tremors or weakness
- Seizures or respiratory distress
What to do right now
- Call your vet or a pet poison helpline right away
- Do NOT induce vomiting because the toxin can be absorbed rapidly
- Remove any contaminated fur and wash the skin with mild soap and water
- If the pet is conscious, give small amounts of water to help dilute the toxin
- Transport the animal to an emergency veterinary clinic for antidote therapy and monitoring
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
