GERD Home > Nexium Drug Information

Nexium® (esomeprazole magnesium) is a medication used to treat a number of conditions affecting the esophagus, stomach, and intestines (such as gastroesophageal reflux disease, erosive esophagitis, and heartburn). Nexium is also known as "the purple pill" because it is a purple capsule with two or three gold rings, depending on the strength. This medicine works by reducing the amount of acid in your stomach by blocking the acid production sites.
Although most people tolerate this medication well, it is not suitable for everyone. Before starting treatment, make sure to talk to your healthcare provider about any other medical conditions you may have or any other medications you are taking (including vitamins and herbal supplements).
The medication comes in the form of capsules or a powder (used to make Nexium oral suspension). Normally, it should be taken once a day, at least one hour before a meal. Nexium comes in a number of strengths, including:
  • Nexium 20 mg capsules
  • Nexium 40 mg capsules
  • Nexium for oral suspension 10 mg packets
  • Nexium for oral suspension 20 mg packets
  • Nexium for oral suspension 40 mg packets.
For more drug information on Nexium, talk to your pharmacist or healthcare provider.
