What levothyroxine formulation are you asking about from Macleods?
“Levothyroxine” comes in multiple strengths and dosage forms (tablet brands can differ by strength and market), and the inactive ingredients can change across those products. To give the right inactive-ingredient list, you need the exact product name/strength (for example, 25 mcg, 50 mcg, 75 mcg) and whether it’s a tablet or another dosage form.
How to find the inactive ingredients for Macleods’ levothyroxine (most reliable sources)
The inactive (non-medicinal) ingredients are typically printed on the:
- package insert (patient leaflet/professional prescribing information), and
- the “composition” section of the carton label, which is specific to that strength.
If you share the strength and dosage form from your box (or a photo/text of the “Composition/Inactive ingredients” section), I can transcribe it accurately.
Why the inactive ingredients may not be identical across strengths
Even within the same manufacturer and product line, inactive ingredients can vary by strength to support:
- tablet size/shape,
- manufacturing process and coating,
- stability and dissolution behavior.
That’s why the correct list is usually strength-specific.
If you’re looking due to allergies or sensitivities
If your goal is to avoid a particular excipient (for example, lactose, dyes/FD&C lakes, gluten-related ingredients), the inactive-ingredient list is the key document for that specific strength. Share what ingredient you need to avoid and the strength/form, and I’ll help you check whether it’s included.
