The two do not affect one another.

No. Alcohol is a poison that never did anybody any good, ever, so stay away from it. It will destroy your brain cells, damage testicular cells that make testosterone, facilitate development of cancer in many organs, cause hepatitis, cirrhosis and pancreatitis etc. There is no safe level of alcohol intake. Quit while you are ahead.

It is obvious to me that the doctor who advised you of abstention from alcohol does not drink! If you were not advised by the prescribing physician or the pharmacist or package insert against simultaneous alcohol ingestion, the answer to your question is "yes," although it is best to abstain from use of alcohol while taking any medication.
