Medical Weight Loss Post-Care Instructions

Follow your prescription
- Use only the prescribed amount and timing, usually earlier in the day. Follow the food directions on your prescription label.

- Check before adding weight-loss products, stimulants or supplements. Report new medicines or pregnancy. Do not drive if dizzy or impaired.
Monitor and follow up
- Keep check-ins and prescription reviews. Monitor blood pressure and pulse as directed; report persistent insomnia, jitteriness, dry mouth or other side effects.
- Seek immediate advice before another dose for reduced exercise tolerance, new ankle or leg swelling, or racing or irregular heartbeat.
