What this means
Does this mean my pharmacy is out of stock?
Not necessarily — a national shortage doesn't mean every pharmacy has run out. Some locations may still have stock, especially of a specific strength or pack size.
What should I do?
Contact your pharmacy before your current supply runs low, and ask your pharmacist about next steps if they're out.
