Alcohol Use and Psychiatric Drugs

"Do not drink alcohol while taking this medication" is in the instructions for many of the drugs prescribed for mental disorders (along with medications for many, many other conditions). Many people think it's because the combination "may cause drowsiness."

While that's quite true, there can be a lot more to the problem. Mixing some psych meds with alcohol can have far more dangerous results, anywhere in the range from alcohol abuse to just having an occasional drink.
