E56 pill imprint seroquel 300 mg manufacturer?

E56 imprint on a 300 mg Seroquel tablet

• What it means
  The “E56” imprint you’re seeing is the identifier that the manufacturer places on the tablet surface. For quetiapine 300 mg tablets, the “E56” imprint is the one that the brand‑name product Seroquel® (manufactured by Eli Lilly & Co.) uses in the United States.

• Why it matters
  Imprint codes are a quick way for pharmacists and prescribers to check that a pill is the right strength and dosage form. However, they don’t always give you the full picture of who actually makes the medication—especially for generics, which can use the same imprint code.

• Generic quetiapine 300 mg tablets
  Many generic manufacturers (e.g., Mylan, Teva, Pfizer, Sandoz) also produce quetiapine 300 mg tablets. Some of these generics may use the same “E56” imprint as the brand‑name product; others may use a different code such as “E5” or a brand‑specific imprint. Because the imprint can be shared, you can’t rely on it alone to determine the manufacturer.

• How to confirm the actual manufacturer

  1. Look at the packaging – the box or blister pack will list the manufacturer’s name and address.
  2. Check the label – the drug’s label (on the tablet itself or the pack) will also have the manufacturer’s name.
  3. Use online databases – sites like Drugs.com, RxList, or the FDA’s “Drugs@FDA” database allow you to look up a product by its imprint code or by generic name and see the list of approved manufacturers.

• Bottom line
  The “E56” imprint you’ve seen on a 300 mg Seroquel tablet almost always points to the Eli Lilly brand product. If you’re looking at a generic and want to be sure who’s making it, check the box, the label, or a reputable drug‑information database instead of relying solely on the imprint code.

If you have the box or label handy and want help interpreting it, feel free to share the details (manufacturer name, logo, etc.) and I can confirm for you.
