WHO IPPF trial standard dose did not show mortality benefit
High-dose protocols used empirically at toxicology centers
No mortality benefit proven for activated charcoal in large trials
Airway protection remains prerequisite
Patient Discharge Instructions
copy discharge instructions
Organophosphate poisoning discharge instructions
What happened
You were treated for poisoning by an organophosphate compound
These chemicals affect the nervous system and can be life-threatening
You were treated with antidotes including atropine and pralidoxime
Full recovery from mild poisoning is expected
Some weakness may persist for several weeks
Activity
Rest at home for at least 1 week
No driving until cleared by your doctor — reaction time may be impaired
No return to agricultural or pesticide work until cleared by occupational health
Warning signs — return to the emergency department immediately
Difficulty breathing or shortness of breath
Even mild breathlessness warrants return
New muscle weakness especially in arms or neck
Weakness that develops days after discharge may be intermediate syndrome
Blurred vision or severe eye pain
Excessive saliva, tearing, or sweating returning
Seizures or loss of consciousness
Confusion or unusual behavior
Chest pain or palpitations
Vomiting that prevents fluids or medications
Follow-up instructions
Return to clinic or GP within 2–3 days
Weakness assessment at follow-up visit
Repeat blood tests may be ordered
Psychiatry or counselling appointment
Intentional exposures require mental health support
Do not delay seeking help for depression or suicidal thoughts
Occupational health referral
If exposure occurred at work
Workplace safety investigation may be required
Prevention
Pesticide storage
Store all pesticides in original labeled containers
Lock away from children and vulnerable individuals
PPE use when handling pesticides
Gloves, mask, eye protection, and protective clothing
Wash thoroughly after any exposure
If you feel you may harm yourself
Call a crisis line immediately
Tell a trusted person and do not be alone
