Disulfiram shouldn’t be given for at least how many hrs. after the patient is abstained from alcohol
**Core Concept**
Disulfiram is a medication used in the treatment of chronic alcoholism by producing an acute sensitivity to ethanol (drinking alcohol). It works by inhibiting the enzyme aldehyde dehydrogenase, which is involved in the breakdown of acetaldehyde, a toxic byproduct of alcohol metabolism.
**Why the Correct Answer is Right**
The correct answer is based on the mechanism of action of disulfiram and its interaction with alcohol. When disulfiram is administered, it inhibits the enzyme aldehyde dehydrogenase, which normally breaks down acetaldehyde into acetate. If the patient consumes alcohol while on disulfiram, the accumulation of acetaldehyde leads to a range of unpleasant symptoms, including nausea, vomiting, and headache. To avoid these symptoms, disulfiram should not be given for at least 12 hours after the patient has abstained from alcohol.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the recommended time interval between alcohol consumption and disulfiram administration is not 2 hours.
* **Option B:** This option is incorrect because the recommended time interval between alcohol consumption and disulfiram administration is not 6 hours.
* **Option C:** This option is incorrect because the recommended time interval between alcohol consumption and disulfiram administration is not 24 hours.
**Clinical Pearl / High-Yield Fact**
It's essential to note that disulfiram should not be given to patients who are currently drinking or who have consumed alcohol in the past 12 hours, as this can lead to a severe and potentially life-threatening reaction.
**Correct Answer:** C. 12 hours
