Does metformin contain titanium dioxide?

Does metformin tablets or pills contain titanium dioxide?

Titanium dioxide is sometimes used as a colorant or opacity agent in certain drug tablet and capsule coatings. Whether metformin contains it depends on the exact product (brand vs. generic), strength, and the manufacturer’s formulation.

How can you check if your metformin dose contains it?

Look at the “Inactive ingredients” section on your specific metformin medication label or package insert. Titanium dioxide, if present, is typically listed there as an excipient (often under names like “titanium dioxide” specifically).

If you tell me the brand name (or the exact generic manufacturer), strength (e.g., 500 mg, 850 mg, 1000 mg), and whether it’s immediate-release or extended-release, I can help you narrow down where to find the inactive-ingredient details for that exact product.
