Nexium (esomeprazole magnesium) is a proton pump inhibitor that decreases the amount of acid produced in the stomach. Nexium is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions involving excessive stomach acid such as Zollinger-Ellison syndrome.
You should not use Nexium if you are allergic to esomeprazole or to similar medicines such as lansoprazole (Prevacid), omeprazole (Prilosec, Zegerid), pantoprazole (Protonix), or rabeprazole (AcipHex).
Heartburn can mimic early symptoms of a heart attack. Get emergency medical help if you have chest pain that spreads to your jaw or shoulder and you feel anxious or light-headed.
Tell your doctor if you have ever had:
severe liver disease;lupus; osteoporosis or low bone mineral density (osteopenia); or low levels of magnesium in your blood.
You may be more likely to have a broken bone in your hip, wrist, or spine while taking a proton pump inhibitor long-term or more than once per day. Talk with your doctor about ways to keep your bones healthy.
