Does prilosec contain aluminum?

No. Prilosec (omeprazole) does not contain aluminum. The active ingredient is omeprazole, often given as a magnesium salt in the OTC form. Inactive ingredients can vary by brand/formulation, but aluminum is not an ingredient in Prilosec.

If you’re taking other antacids that contain aluminum (like aluminum hydroxide) and you’re worried about interactions, talk to your doctor or check the labels. If you want, tell me which exact product and strength you have and I can help confirm the ingredient list.
