S.D. Codified Laws § 27A-15-48
A minor sixteen years of age or older, whether involuntarily committed or admitted by a parent, has the right to refuse psychotropic medication. Such minor also has the right to refuse convulsive or shock therapy or electric shock. If psychotropic medication or convulsive or shock therapy or electric shock is prescribed by the minor's treating psychiatrist upon that treating psychiatrist's written determination that the treatment is the least restrictive treatment alternative medically necessary for improvement of the minor's serious emotional disturbance, which opinion is concurred in by a consulting physician, the treatment may be administered with the informed consent of the minor's parent, guardian, or other legal custodian pending the judicial determination required in § 27A-15-50. Documentation of the minor's refusal, and the treating psychiatrist's written determination and the consulting physician's concurrence shall be made part of the minor's medical records.
