Medication Refills and Follow-up Appointments

Prescriptions for controlled substances need to be hand-written and cannot be called into your pharmacy. Please discuss any prescription refill needs during your follow-up appointment or call at least one week before a medication refill is needed. Appropriate and timely follow-up appointments help minimize the need for last minute medication refills. Dr. Pionk routinely schedules one-month follow-up visits with medication changes and requires regular maintenance visits every 3-4 months depending on the behavioral condition.

Appointment Changes and Cancellations

We recommend scheduling follow-up appointments consistently to ensure the most convenient availability and to help minimize last minute requests. You may schedule, change or cancel appointments by using the online appointment scheduler or by calling our office at 858-558-7337. We advise 24-hour advance notice for cancellations to avoid additional charges.
