Can you take Dexlansoprazole while pregnant?
Last updated September 7, 2026.
Dexlansoprazole is not a first choice during pregnancy, though it can be continued or started under your clinician's guidance when simpler steps do not control your reflux. Heartburn affects a large share of pregnancies, and treatment usually starts with meal and sleep habits, then antacids, then acid-reducing medicines. Among prescription options, famotidine and omeprazole have the largest body of human pregnancy data, so many clinicians switch you to one of those rather than keep dexlansoprazole. Dexlansoprazole itself has less pregnancy-specific data, which is a reason for caution rather than a known harm. If you already take it for erosive esophagitis or severe reflux, keep taking it until you have talked with your prenatal clinician, since uncontrolled reflux has costs of its own.
What to do
- Start with habits: Eat smaller meals, stay upright for two to three hours after eating, and raise the head of your bed a few inches.
- Try an antacid first: Calcium carbonate antacids are a usual first step in pregnancy; skip baking soda remedies, which add a large sodium load.
- Ask about better studied drugs: Famotidine and omeprazole have more pregnancy safety data than dexlansoprazole and often work just as well.
- Do not stop on your own: If dexlansoprazole treats erosive esophagitis or severe reflux, keep taking it until your clinician gives you a plan.
- Use the smallest effective dose: Take the lowest dose that controls symptoms, and revisit whether you still need it each trimester.
- Get checked promptly for: Trouble swallowing, vomiting blood, black stools, weight loss, or upper right belly pain with headache or vision changes.
