## Why this rule exists

Promoting prescription medication over SMS raises both regulatory and safety exposure, and carriers refuse the category. Pharmacy operations — refill reminders and pickup notices to existing patients — remain registrable, and confusing the two is the common failure.

## How to fix it

Remove promotional drug content. Reframe as operational patient messaging — refills, pickups, appointments — which is registrable under CUSTOMER_CARE or ACCOUNT_NOTIFICATION.
