@Trixie21 Thanks for your reply. As far as I can tell, the FDA controls the expiration and it is set at 9 days. There are advocates who are trying to change it (see link below) but due to current restrictions, only 1 week of supplies can be distributed by infusion companies. Our infusion company: https://optioncarehealth.com/ is no different.
