Poison schedule - S
Summary:
Details:
Poison schedule - S6
Mammalian toxicity - Harmful.
Acute oral LD50 - 1500-2100 mg/kg (rats), [For comparison table salt is 3000 mg/kg] - Harmful.
Acute dermal LD50 - >5000 mg/kg (rabbit).
Skin - Non irritating.
Eye - Moderately irritating
Vapour inhalation - LC50 - > mg/L air (rat).
Chronic oral toxicity NOEL - ppm for two years.
Not carcinogenic, oncogenic, mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).
Acceptable Daily Intake (ADI) -
Repeated minor doses may have a cumulative poisoning effect.

23. TOXICITY SYMPTOMS:

Mild exposure may lead to headache, blurred vision, weakness, giddiness, sweating, mild chest pain, nausea and vomiting.
Severe exposure may lead to cyanosis, muscular twitching, spasms. miosis and respiratory paralysis.
Symptoms usually appear from 1 to 3 hours after exposure.

24. FIRST AID:

If SWALLOWED - Induce vomiting preferably with Ipecac Syrup APF and give one atropine tablet every 5 minutes until dryness of the mouth occurs. See a doctor immediately.
If in EYES - Irrigate for 15 minutes with plenty of water.
If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water. Give one atropine tablet every 5 minutes until dryness of the mouth occurs. See a doctor immediately.
If INHALED - Remove patient to fresh air.
If patient has symptoms or is concerned contact a doctor immediately.
Advice to doctor - Treat symptomatically and if necessary apply artificial respiration. Give atropine sulphate at 5-10 minute intervals until dryness of the mouth occurs. this will relieve muscarinic manifestations. Don't give atropine to cyanosed patients. In cases of severe poisoning (muscle twitching and respiratory depression) give pralidoxime preferably less than 48 hours after exposure to relieve nicotinic effects.
Contraindications - Never give patient morphine, theophylline or theophylline-ethylenediamine. Large amounts of intravenous fluids are contraindicated because of threat of pulmonary oedema.
