The document provides 7 precautions for developing repeat prescriptions (Rx) habits with doctors: 1) Avoid focusing on too many products at once, 2) Talk about the priority brand first to trigger past discussions, 3) Address doctors' queries and concerns to avoid hurting egos, 4) Be aware of prescription levels to maintain enthusiasm, 5) Avoid standard details to keep doctors engaged, 6) Prevent prescriptions from bouncing to maintain habits, and 7) Establish prescription habits for priority brands before emphasizing others to maximize sales volume. Developing steady prescription habits for a single brand generates greater sales than sporadic prescriptions across multiple brands.
