Silditop 100 On the medicine packaging: The batch number is printed on the strip/blister and the outer box label along with the manufacturing and expiry dates. This is where manufacturers mark batch/Lot details. On the label or blister foil: Often it’s printed with a code like B. No / Batch / Lot followed by a series of letters/numbers. How to check it further If you want to verify authenticity/type details beyond just reading the number Scan any QR code on the packaging (if present) — in India, many medicines now include QR codes that show product details including batch number, manufacturing date, and expiry when scanned with a smartphone camera. This is part of the government’s Track & Trace system. Check your Silditop 100 bill or invoice — licensed pharmacies sometimes print batch numbers on the bill along with the medicine name, helping you verify packaging vs receipt. Contact the manufacturer directly — if you have the batch number and are unsure about authenticity or details, reach out to the manufacturer’s customer care with the batch number for confirmation. Many companies can verify whether a batch was legitimately produced. Safety tip Batch numbers help trace production and are used in recalls or quality checks. If the batch number is missing, unreadable, or doesn’t match the code after scanning the QR, it might be a sign the product isn’t genuine — consider not using it and consult a pharmacist.
