Does metoprolol contain titanium dioxide?

Does metoprolol contain titanium dioxide?

Metoprolol products can include inactive ingredients (excipients), and whether titanium dioxide is present depends on the specific metoprolol brand and formulation (for example, tablet strength, manufacturer, and whether it’s an immediate-release or extended-release version).

If you check the “Inactive ingredients” section of that exact product’s label or package insert, you’ll see whether titanium dioxide is listed. For many solid oral drugs, titanium dioxide is used as a colorant in some tablet coatings, but it is not universal across all metoprolol products.

How to confirm for your exact metoprolol

Look for these on the package insert or label:
- “Inactive ingredients” (or “Ingredients” excluding the active drug)
- Any mention of “titanium dioxide” (sometimes listed as “titanium dioxide (E171)” in some jurisdictions)

If you tell me the exact product, I can narrow it down

If you share the metoprolol:
- brand name (or manufacturer),
- strength (e.g., 25 mg, 50 mg, 100 mg),
- and whether it’s extended-release (ER) or immediate-release (IR),
I can help you determine whether that specific version commonly lists titanium dioxide in its inactive ingredients.
