Final answer:
Drinking alcohol while taking disulfiram can lead to unpleasant symptoms such as flushing, nausea, dizziness, sweating, headache, and low blood pressure.
Step-by-step explanation:
When drinking alcohol while taking disulfiram, one can expect to experience unpleasant symptoms due to the medication's interaction with alcohol. Disulfiram inhibits the enzyme that converts acetaldehyde (a byproduct of alcohol metabolism) to acetic acid, leading to the accumulation of acetaldehyde in the body. This can result in symptoms such as flushing, nausea, dizziness, sweating, headache, and low blood pressure.
