What Esperal Does
Esperal doesn’t Block cravings directly. It changes how your body handles alcohol. Disulfiram blocks an enzyme (aldehyde dehydrogenase). So if you drink even a small amount acetaldehyde builds up. That leads to flushing, pounding headache, nausea, vomiting, chest discomfort, fast heartbeat, and a drop in blood pressure. Not fun, and honestly, that’s the point. The strong, quick reaction helps you avoid alcohol and stick with sobriety.
