Can Nexium Cause Gas and Diarrhea?

Serious stomach conditions may occur while using Nexium alone or together with antibiotics. Check with your doctor immediately if you experience stomach cramps, bloated feeling, watery and severe diarrhea which may also be bloody sometimes, fever, nausea or vomiting, or unusual tiredness or weakness.

How Common is Diarrhea With Nexium?

Diarrhea is experienced by about 3% of Nexium users, and nausea occurs in about 2% of people taking the medicine. If nausea is persistent or progresses to vomiting, contact your healthcare provider immediately. Persistent diarrhea could be an indicator of a serious adverse effect called colitis, and also requires immediate medical intervention.
