Alcohol Withdrawl

- Discussion: 
   -  onset- usually a few hours to 10 days after last drink (Usually 6-48 hr); 
   - early symptoms: tend to be mild; 
          - nausea, vomiting, anorexia, insomnia, diaphoresis, agitation, tachycardia, HTN, if seizures occur,
          - common abstinence syndrome, occurring at 6-8 hr, is the earliest withdrawl syndrome and is often present when the patient awakens;
          - seizures appear at 7 to 48 hr and are usually single rather than recurrent; 
          - alcoholic ketoacidosis is usually seen later at 24 to 72 hrs;
   - late symptoms: tend to be severe; worsening of above symptoms,
   - Delerium Tremens:
- acute psychosis with hallucinations, delusions, disorientation, agitation; DT's 5-15% fatal w/o treatment, <1% treated;
          - DT is usually seen at 3-5 days, but may be seen as late as 14 days; 

* Treatment:
      - provide thiamine - chlordiazepoxide has been widely marketed and used for ETOH withdrawl.
      - Diazepam, Lorazepam, Oxazepam have more rapid onset of action and greater anticonvulsant activity;
      - both Chlordiazepoxide and Diazepam are poor drugs when given IM because their absorption is slow, erratic, and incomplete;
      - when treating ETOH withdrawl, the required dosage of benzodiazepine may be quite large and should be carefully titrated to the symptoms;
      - Note that the following are NOT recomended:
              - Barbiturates (Resp Depression, Drug Interactions),
              - Antihistamines (Anticholinergic effects may worsen toxic psychotic symptoms);
              - Antipsychotics (contraindicated because of risk of orthostatic hypotension and Seizures)
