What should I know about Nexium before taking it?

Be sure to talk to your doctor about allergies to medication as well as any medications or herbal supplements you are currently taking. If you have a history of liver disease or other problems with your liver, you should mention this to your doctor as well. Women who are pregnant or may become pregnant or are breastfeeding should weigh the pros and cons of taking Nexium, as the medication's long-term effects on fetal development are not fully understood at this time.
