Ingredients in prilosec?

Prilosec’s active ingredient is omeprazole. The exact inactive ingredients (excipients) vary by formulation and country (capsule vs tablet, strength, etc.).

If you tell me:
- which Prilosec product you have (e.g., Prilosec OTC 20 mg capsule, or another version),
- and your country,

I can look up the exact ingredient list for that product. You can also check the label or package insert on the carton for the full list of inactive ingredients. If you have allergies or needs (e.g., to certain colorants, lactose, etc.), share them and I can help interpret.
