Not sure of your context here, but this might be an option, or "information for medical practitioners".
Unless you know it's directed at doctors, I'd avoid the word "physician" here, as that's just one of many positions in the "gremio médico", i.e., nurses, dentists, pharmacists, etc.

A health professional, health practitioner or healthcare provider (sometimes simply "provider") is an individual who provides preventive, curative, promotional or rehabilitative health care services in a systematic way to people, families or communities.

A health professional may operate within all branches of health care, including medicine, surgery, dentistry, midwifery, pharmacy, psychology, nursing or allied health professions. A health professional may also be a public/community health expert working for the common good of the society.
