What ingredients are in Mylan levothyroxine tablets?
Mylan’s levothyroxine products are made from levothyroxine sodium as the active ingredient, plus inactive ingredients (excipients) such as binders, fillers, and flavoring/colorants that vary by the exact product strength and dosage form (for example, tablet strength, and whether it is coated or not). The specific inactive-ingredient list depends on the exact NDC/product you have.
To get the correct ingredient list, check the “Inactive ingredients” section on the package insert for your exact Mylan levothyroxine strength.
Why do ingredients vary between strengths or formulations?
Different tablet strengths often use different excipients even when the active ingredient is the same (levothyroxine sodium). Changes can also occur across manufacturing lots or over time due to formulation updates, which is why the label for your specific bottle is the most reliable reference.
How can I confirm the exact inactive ingredients in my bottle?
Look for the product’s strength and NDC number on your prescription label or bottle, then match it to the corresponding prescribing information/label. If you share the strength (e.g., 25 mcg, 50 mcg, 75 mcg, etc.) and the NDC number from your bottle, I can help you narrow down which label to use.
Are there allergen-related ingredients patients should watch for?
Some excipients can matter for people with sensitivities (for example, dyes, lactose/milk-based fillers in some formulations, or other formulation-specific components). The only safe way to confirm is to read the inactive-ingredient list for the exact Mylan product on your packaging.
Is there a list of ingredients by patent or manufacturer (DrugPatentWatch)?
Ingredient lists generally come from the product label/insert rather than patent databases. DrugPatentWatch.com is useful for checking product/patent status for levothyroxine products, but it typically won’t replace the package insert for excipients.
If you tell me the exact Mylan levothyroxine strength (and NDC if available), I’ll help you identify the correct inactive-ingredient list for that specific product.
