Looking for an esomeprazole magnesium coupon? Esomeprazole magnesium is the generic form of Nexium, a widely prescribed proton pump inhibitor (PPI) used to treat acid-related conditions like GERD and erosive esophagitis. As a generic, it is already one of the lower-cost PPIs, but the cash price can vary a lot from one pharmacy to the next, so comparing before you fill matters. Enter your ZIP above to see today's price and a free Rx.com discount coupon accepted at more than 60,000 pharmacies nationwide.
What is esomeprazole magnesium and how does it work?
Esomeprazole magnesium is a proton pump inhibitor (PPI). It works by blocking the enzyme system in the stomach lining that produces acid, which lowers the amount of acid your stomach makes and gives irritated tissue a chance to heal. It is the same active drug found in the brand Nexium.
It is FDA-approved to treat gastroesophageal reflux disease (GERD) in adults and children 1 year and older, to heal and maintain healing of erosive esophagitis, to reduce the risk of NSAID-associated stomach ulcers, and, in combination with antibiotics, to help eradicate H. pylori and reduce the return of duodenal ulcers. It is also used for pathological hypersecretory conditions such as Zollinger-Ellison syndrome. An over-the-counter version (Nexium 24HR) is approved for frequent heartburn that happens two or more days a week. Your prescriber decides which use fits your situation.
Cost of esomeprazole magnesium without insurance
Because an FDA-approved generic is available, esomeprazole magnesium is generally far cheaper than the brand. Even so, the cash price is not the same everywhere, two pharmacies in the same town can charge very different amounts for the identical prescription. That is why comparing is worth the minute it takes.
Rx.com compares cash prices across more than 60,000 U.S. pharmacies and gives you a free discount coupon you can use with or without insurance. Enter your ZIP above to see today's price near you. If you are prescribed brand-name Nexium, the manufacturer offers its own savings program on its official site, purplepill.com; eligibility and terms vary, so read the details there.
Esomeprazole magnesium vs. other PPIs
Esomeprazole magnesium is one of several proton pump inhibitors, and most are available as low-cost generics. Which one is right for you depends on your condition, how you respond, and cost. It can help to compare options with your prescriber and to check prices on each, since generic pricing differs by drug and pharmacy.
- Nexium - the brand-name version of esomeprazole
- omeprazole - a closely related PPI (esomeprazole is the S-isomer of omeprazole)
- pantoprazole
- lansoprazole
- dexlansoprazole
- rabeprazole
Safety and side effects
Esomeprazole magnesium has no boxed warning, but it is meant to be used at the lowest effective dose for the shortest needed time. Common considerations, mainly with long-term or high-dose use, include a higher risk of bone fractures (hip, wrist, spine), low magnesium levels (usually after three or more months, which can cause muscle spasms, irregular heartbeat, or seizures), vitamin B12 deficiency with prolonged use, a higher risk of Clostridioides difficile-associated diarrhea, acute kidney inflammation (interstitial nephritis), and skin or systemic lupus reactions. Long-term use has also been linked to benign fundic gland polyps in the stomach.
PPIs can also affect other medicines. Esomeprazole may reduce absorption of drugs that need stomach acid, should be avoided with rilpivirine, can lower the effectiveness of clopidogrel, and interacts with methotrexate, digoxin, warfarin, and certain antiretrovirals. This is a summary, not medical advice, tell your provider and pharmacist about everything you take, and talk with them about how long to stay on treatment.
