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.
