My last therapist was very knowledgeable about medications. He had gone through a program on psychopharmacology. It was incredibly helpful because if I was noticing an issue, he was able to point me in the right direction. He knew whether something going on was a therapy thing or a med thing. He could converse and consult knowledgeably with the psychiatrist he worked with and with my own psychiatrist. It became one of the most helpful aspects of having him as my therapist.
