Currently Available

NEXIUM is a proton pump inhibitor (PPI). There are other branded PPIs available and only some of them have generic equivalents. NEXIUM does not have a generic equivalent.

It is important to know that not all medications work the same for all patients, including the generic equivalents.

When your doctor prescribes a medication, it is because it has been determined it is the right one for you.

If your doctor prescribes NEXIUM make sure that’s what your pharmacist gives you.


Tips for making sure you get NEXIUM and not a generic

  • Ask your doctor to write “medically necessary,” “may not substitute,” or "dispense as written” on the prescription
  • Be familiar with what your medication looks like and know both the brand and generic name of that medicine
  • Request that your physician and/or pharmacist put a note in your records indicating that you take a particular medication and not to switch it
  • When you pick up your prescription at the pharmacy, check the label to make sure it reads NEXIUM® (esomeprazole magnesium)
