Nexium® (esomeprazole magnesium) is a prescription drug used for treating GERD (gastroesophageal reflux disease) and various other conditions related to the esophagus, stomach, and intestines.
As with any medication, side effects are possible with Nexium. Some of the most common side effects that have been reported in clinical studies include headache, nausea, abdominal pain, and diarrhea. In most cases, Nexium side effects are mild and either do not require treatment or can be treated quite easily.
It is important to know that serious reactions to Nexium could also occur. You should contact your healthcare provider right away if you experience difficulty swallowing, chest pain, an unexplained rash, or blurred vision.
