Omeprazole excipients?

Excipients (inactive ingredients) for omeprazole vary by product and dosage form (capsule vs tablet) and by manufacturer. The exact list is in the product’s labeling.

If you can tell me the specific product (brand or generic) and the dose (e.g., 20 mg capsule, 40 mg tablet), I can pull the exact “Inactive ingredients” from the label.

In the meantime, here’s what you might commonly see, to give you an idea:

- Capsule forms (e.g., omeprazole 20 mg capsules):
- Capsule shell: gelatin (and sometimes colorants in the cap/body such as titanium dioxide and iron oxides)
- Fill/contents: may include microcrystalline cellulose, lactose or starch as fillers, magnesium stearate as a lubricant, and sometimes disintegrants (e.g., crospovidone)

- Tablet forms (enteric-coated or delayed-release):
- Fillers/binders: microcrystalline cellulose, lactose, hypromellose (HPMC), magnesium stearate
- Coating: an enteric coating such as methacrylic acid copolymer (Eudragit) or cellulose acetate phthalate to protect the drug from stomach acid
- Other possible binders/disintegrants: crospovidone, sodium starch glycolate

Common allergens or restricted ingredients to watch for:
- Lactose or other sugars in some formulations
- Gluten-containing binders are unlikely but can occur in some brands
- Colorants (e.g., certain iron oxides) in colored capsules or tablets

Where to check precisely:
- The product label or package insert (inactive ingredients section)
- DailyMed (US) or the equivalent labeling database for your country
- The manufacturer’s website or patient information leaflet

If you share the exact product name and dosage, I’ll list the exact excipients from the labeling.
