In general, what kind of symptoms accompany mild alcohol withdrawal?
Mild alcohol withdrawal: Symptoms similar to other depressants
What can result from severe alcohol withdrawal? What mortality rate is associated with this?
Severe alcohol withdrawal can cause autonomic hypersensitivity and DTs (5-15% mortality rate)
What is the treatment for DTs?
Treatment for DTs: Benzodiazepines.

What are 5-6 specific signs/symptoms of opioid intoxication? Which in particular is seen in opioid overdose?
(1) Euphoria (2-3) Respiratory and CNS depression (4) Decreased gag reflex (5) Pupillary constriction (pinpoint pupils) (6) Seizures (overdose)
What is the treatment for opioid overdose?
Treatment: Naloxone, Naltrexone
What are 9 specific signs/symptoms of opioid withdrawal?
(1) Sweating (2) Dilated pupils (3) Piloerection (“cold turkey”) (4) Fever (5) Rhinorrhea (6) Yawning (7) Nausea (8) Stomach cramps (9) Diarrhea (“flu-like” symptoms)
What is the treatment for opioid withdrawal?
Treatment: Long-term support, Methadone, Buprenorphine
What major sign/symptom is associated with barbiturate intoxication?
Marked respiratory depression
What kind of safety margin do Barbiturates have?
Low safety margin
What is the treatment for Barbiturate intoxication/overdose?
Treatment: Symptom management (assist respiration, increase BP)
What 2 symptoms/consequences are associated with Barbiturate withdrawal?
Delirium, life-threatening cardiovascular collapse
How do Benzodiazepines compare to Barbiturates in terms of their safety margin?
Greater safety margin (than Barbiturates)
What are 2 signs/symptoms associated with Benzodiazepine intoxication?
(1) Ataxia (2) Minor respiratory depression
What is the main treatment for Benzodiazepine intoxication/overdose? What else should be considered as a treatment option?
Treatment: Supportive care; Consider Flumazenil (competitive benzodiazepine antagonist)
What are 4 signs/symptoms of Benzodiazepine withdrawal? What is an important consideration in the case of Benzodiazepine reversal?
(1) Sleep disturbance (2) Depression (3) Rebound anxiety (4) Seizure (can be triggered by reversal with flumazenil)

Nonspecific: (1) Mood elevation (2) Psychomotor agitation (3) Insomnia (4) Cardiac arrhythmias (5) Tachycardia (6) Anxiety
What is the major consequence of Stimulant withdrawal? What 4 symptoms characterize this consequence?
Nonspecific: post-use “crash,” including depression, lethargy, weight gain, headache.
What are 9 specific signs/symptoms of (mild-moderate) amphetamine intoxication?
(1) Euphoria (2) Grandiosity (3) Pupillary dilation (4) Prolonged wakefulness and attention (5) Hypertension (6) Tachycardia (7) Anorexia (8) Paranoia (9) Fever
