What to say at the pharmacy
“Before you fill it, what would I pay for generic metformin?”
Paying cash? Ask for the cash price. With insurance, ask what your plan charges.
Good to know
- Different companies’ metformin can look different. The FDA requires each to work the same way.
- Don’t stop or change a medicine without talking to your pharmacist or prescriber.
