Substance Use Toxicity and Management Summary
🔷 Stimulants
Examples: Amphetamines, Cocaine, MDMA (Ecstasy)
Clinical Effects:
- CNS excitation, sympathomimetic features
- Diaphoresis, flushing, mydriasis
- Hallucinations, agitation
- May precipitate:
- Acute coronary syndromes (ACS)
- Arrhythmias
- Hypertension, possible hypotension with severe toxicity
Management:
- Sedation (e.g. benzodiazepines)
- IV fluid resuscitation
- Cooling measures for hyperthermia
- Monitor ECG and cardiovascular function
🔷 Cannabis Toxicity
Clinical Features:
- Ocular: Red eyes, ↓ intraocular pressure (IOP)
- Autonomic: Dry mouth, dry skin, ↑ heart rate
- Neurological/psychiatric:
- Depersonalisation, disorientation
- ↓ inhibition, mood changes, memory impairment, poor attention
- Psychosis, agitation
- Hyperemesis syndrome
Management:
- Symptomatic treatment:
- Antiemetics
- Benzodiazepines (if severe agitation or anxiety)
- Antipsychotics (if psychotic features)
🔷 Opioid Overdose
Clinical Features:
- CNS depression: Drowsiness, coma
- Respiratory depression
- Hypothermia
- Miosis (pinpoint pupils)
- ↓ HR and BP (but may be normal)
Management:
- Airway support and ventilation
- Naloxone IV boluses:
- Start with 100 micrograms (mcg) IV, repeat every 2–3 minutes as needed
- Titrate to respiratory rate >10/min
- Consider continuous infusion if long-acting opioids involved
🔷 Opioid Withdrawal
Preferred pharmacotherapy: Buprenorphine-controlled withdrawal
Used to prevent withdrawal symptoms during detoxification (vs long-term maintenance).
Initial Buprenorphine Regimen:
- Day 1: 4–8 mg SL as a single daily dose
- Day 3: Can increase to 12 mg
- Gradually taper over 3–5 days
Adjunctive Treatments:
- Clonidine: 5–15 mcg/kg/day orally in 3 divided doses × 7–10 days, then taper
- Diazepam: 5–20 mg PO QID with caution (risk of sedation/overdose)
- Use only if supervised
- Note: Buprenorphine is preferred over clonidine or methadone in withdrawal
🔷 Opioid Maintenance Treatment (for long-term dependence)
Should be initiated with specialist input.
1. Methadone
- Initial: 20 mg PO daily
- Stabilisation: Gradual increase over 3 weeks
- Maintenance: 50–80 mg/day (max 120 mg/day)
- Caution: Doses >40 mg can cause overdose, especially in unwell patients
2. Buprenorphine
- Initial: 2–8 mg SL daily
- Maintenance: Titrate to 8–24 mg/day or alternate-day dosing
- Safer profile: Lower risk of overdose, but may precipitate withdrawal if started too soon after full opioid use
3. Naltrexone
- Requires opioid-free state: use naloxone challenge test first
- Initial: 25 mg PO on Day 1, then increase to 50 mg daily from Day 2
- Requires close supervision and comprehensive counselling
🔷 Key Notes on Opioid Dependence
Offer naloxone (Take Home Naloxone) to high-risk patients
Natural history: Many individuals outgrow dependence, with many achieving recovery by mid-30s
Psychosocial support (counselling, housing, employment, peer support) is essential
