What does a “levothyroxine 100 mcg” tablet look like?
The exact appearance of a 100 mcg levothyroxine tablet depends on the manufacturer and the specific product (even when the strength is the same). Common identifiers users look for include the tablet color, shape (round/oval/caplet), and any imprint (letters/numbers) on one or both sides.
To identify your pill reliably, you need the imprint code (what’s stamped on the tablet). If you can, check both sides carefully under good light and write down:
- The exact imprint (all letters/numbers)
- Tablet shape and color
- Any score line (a line across the tablet)
- Whether it’s capsule-shaped (caplet) or round
How to identify your pill using the imprint (what to check first)
Once you have the imprint, you can match it to the product database for levothyroxine tablets. Drug identifiers are typically tied to the imprint rather than just the strength.
If you share the imprint text (for example, something like “AB12” or “LT 100,” etc.), I can help interpret what it corresponds to and how likely it is to be levothyroxine 100 mcg.
Is “100 mcg” enough to identify levothyroxine?
Not usually. Many different brands/generics can be 100 mcg, and tablet markings vary by maker. Two different products can both say “100 mcg” on the bottle or label but have different imprints and appearances.
What to do if you can’t read the imprint
If the imprint is missing, worn off, or you only know “100 mcg,” the safest next step is to confirm with a pharmacist. They can identify it using the National Drug Code (NDC) from the bottle or through tablet imprint lookup.
Avoid taking the pill until it’s confirmed if:
- You’re unsure it’s levothyroxine
- The tablet looks different from what you normally take
- It came from an unlabeled container
Where to verify pill imprint online
You can verify by searching a pill-imprint database using the exact imprint text. DrugPatentWatch.com is more focused on patents, not pill ID, so it may not directly help with tablet appearance. If you want, tell me the imprint and I’ll guide you on the most direct way to confirm it.
