Which medicines commonly contain titanium dioxide (TiO2)?
Titanium dioxide is an ingredient used mainly to give tablets or capsules a white color/opacity. That means you can find it in some brand-name and generic solid oral medicines where the coating or the tablet/capsule shell uses TiO2 for appearance.
However, the exact list of products containing TiO2 is not universal across all strengths and manufacturers. The presence of TiO2 can vary by formulation, country, and even by different lots or package forms.
How to check whether a specific drug contains titanium dioxide
If you want to confirm TiO2 for a particular product, the most reliable route is the medicine’s official labeling for “Inactive ingredients” (often listed in the package insert, patient leaflet, or product monograph). Search within the label for terms like:
- titanium dioxide
- TiO2
- E171 (the EU food additive code; sometimes appears in excipient listings)
Drugs containing TiO2 besides amoxicillin: what’s typically found
Without a specific country, ingredient list source, or the exact amoxicillin product you mean, I can’t produce a trustworthy, exact catalog of “all drugs containing TiO2.” Titanium dioxide is widely used across many types of tablets/capsules (for example, in some coatings and shells), so there are many potential candidates—but which ones depends on the specific formulation.
If you share any of the following, I can help you identify TiO2-containing alternatives more precisely:
- Your country (and whether you’re looking for OTC or prescription)
- The exact amoxicillin brand/generic name and strength you’re using to compare
- One or two drugs you’re considering (so we can check their inactive-ingredient lists)
If the concern is safety: what changes if TiO2 is removed
In markets that restrict or limit TiO2 in certain uses, manufacturers sometimes reformulate tablets/capsules to use alternative colorants/opacifiers. That can change the inactive ingredients while keeping the active drug the same, which is why checking the specific product labeling matters.
Fast next step
Tell me the country you’re in and the exact amoxicillin product you referenced (brand + strength), and list 3–10 other drug names you want to check. I’ll then pull the inactive-ingredient information to identify which alternatives contain titanium dioxide.
