There are multiple drugs to help with alcohol dependency.

The following is from Mayo's webpage:

Oral medications:
A drug called disulfiram (Antabuse) may help prevent you from drinking, although it won't cure alcohol use disorder or remove the compulsion to drink. If you drink alcohol, the drug produces a physical reaction that may include flushing, nausea, vomiting and headaches.

Naltrexone, a drug that blocks the good feelings alcohol causes, may prevent heavy drinking and reduce the urge to drink.

Acamprosate may help you combat alcohol cravings once you stop drinking.
