It's better to use the term Medicine because the word "drugs" so often refers to illegal drugs.

In the context you're using the word "medication" is probably best. For example, is the patient currently taking any medication?. The word drugs is used very commonly regardless of the illegal connotations. That is, the pharmaceutical companies are generally spoken of as producing drugs, not medicines.

Because of the popular connotations of the word 'drug ' it might be better to use medicine or medication when talking to patients, but drug would be more appropriate when talking to other professionals. I am a qualified, although no longer practising, doctor, and that is the way I tended to use words when I was practising.
