Best Practices for Avoiding Hidden Gluten

Tell the pharmacist that your medications must be gluten-free.

Remind them every time you have a prescription filled.

They would need to look up this information from the manufacturer.

When generic medications are available, your insurance company will probably not approve the brand-name drug.

Generic medications, however, are not required to contain the same fillers as the brand name formulation.

Just because you’ve confirmed that a brand-name medicine is gluten-free doesn’t mean the generic form is safe.

Likewise, one generic being gluten-free doesn’t mean all generics are.

Few drug companies have a policy of avoiding gluten completely.

Ask to be given a second-choice prescription in case the first-choice medicine turns out to be unsafe.
