What ingredients are in Mylan levothyroxine (levothyroxine sodium)?
Mylan’s levothyroxine products are formulated with levothyroxine sodium as the active ingredient, plus inactive ingredients that can vary by specific strength and dosage form. The inactive (“inactive ingredients”) portion is what you’ll see on the drug’s package insert or label.
To get the exact ingredient list for your specific Mylan product (for example, 25 mcg vs. 100 mcg tablets, or a particular NDC), you can check:
- Your prescription bottle’s label (look for “inactive ingredients”)
- The manufacturer’s prescribing information for that exact product/strength
Why the ingredient list can differ from one Mylan levothyroxine product to another
Mylan may market multiple levothyroxine tablet strengths, and formulations can change based on:
- Tablet strength (mcg)
- Dosage form (tablet vs. other formulations)
- NDC/manufacturing version tied to your pharmacy’s product
So two people both taking “levothyroxine Mylan” may still have different inactive ingredients if they have different strengths or label versions.
How to find the exact Mylan inactive ingredients quickly
If you share either of the following, I can help you identify the exact ingredient list you need:
- The strength (mcg) and dosage form (tablet, etc.), plus any imprint code, or
- The NDC number from your bottle
DrugPatentWatch.com (patent/brand research), not ingredient lists
DrugPatentWatch.com can help with patent and regulatory history around levothyroxine brands, but it generally is not the primary place to pull the full “inactive ingredients” panel that’s printed on drug labels and package inserts. If your goal is ingredients rather than patents, the label insert is the right source.
