Is your Semaglyn real? Sealed-pen visible checks

If you have a Semaglyn pen at home and you're searching whether it's fake, you're doing the right thing to pause before injecting. Semaglyn is the semaglutide GLP-1 brand manufactured by Zydus Lifesciences for the Indian market. It is one of the newer Indian-origin semaglutide options available alongside Wegovy India (Novo Nordisk), Obeda (Dr Reddy's) and others.

Because semaglutide pens are expensive and demand is high, counterfeit and grey-market pens do circulate — both online and in some smaller pharmacies. This page walks you through red flags to look for on a sealed Semaglyn pen and carton, before you break the seal. We can't and won't tell you a pen is definitely real from a photo — only Zydus and CDSCO can do that — but we can help you spot patterns that many people commonly report on suspicious units.

For general cross-brand checks that apply to all GLP-1 pens in India, see our hub: /safety/how-to-spot-a-fake-glp1-pen. For Semaglyn's manufacturer details, pack sizes and current pharmacy prices, see /brands/semaglyn.

Red flags to look for

These are observational checks on a sealed Semaglyn pen and its outer carton. Do not unbox or inject anything you are unsure about.

• Brand-name misspelling. The legitimate Zydus carton prints the brand as Semaglyn — one word. Many people commonly report counterfeits with subtle misspellings like Semaglynn, Semaglin, Semaglyne, or Semaglyn-S. Compare the spelling letter-by-letter against Zydus's published pack image on /brands/semaglyn.

• Holographic seal / tamper strip. Genuine Indian pharma cartons from Zydus typically carry a tamper-evident seal or holographic element. A carton that opens without breaking any seal, or where the hologram looks like a flat printed sticker with no colour shift when tilted, is a commonly reported red flag.

• Batch number, manufacturing date, expiry format. Indian pharma labelling convention is B.No., Mfg. and Exp. in MM/YYYY or MM-YYYY format, printed (not handwritten, not stickered over). Smudged ink, a sticker covering the original batch, or a font that differs from the rest of the carton is a red flag.

• MRP printing. The MRP must be printed in ₹ with the words Maximum Retail Price (incl. of all taxes) on the carton itself. A pen sold significantly below typical Indian pharmacy prices listed on Apollo, Tata 1mg, Pharmeasy or Netmeds is a commonly reported pattern on counterfeits — see current ranges on /brands/semaglyn.

• CDSCO / Indian-import licence details. Zydus is an Indian manufacturer, so the carton should show an Indian manufacturing licence number and Zydus's registered address (Ahmedabad / Gujarat). A carton showing only a foreign address, or no licence number at all, is a serious red flag.

• Font and colour consistency. Compare the Semaglyn carton against the manufacturer's published packaging photo. Mismatched shades of the brand colour, uneven kerning, blurry logos, or a Zydus logo that looks pixelated are patterns many people commonly report on suspect units.

• Pen body vs carton mismatch. The dose-window numbering, label colour and pen length on the device should match what is shown on Zydus's official material. A pen that looks like a generic insulin pen with a Semaglyn sticker pasted on is a major red flag.

• Cold-chain and storage cues. Semaglutide pens are label-stated to be stored refrigerated (2–8°C) until first use. A pen sold at room temperature from a non-refrigerated shelf, or arriving by courier without any ice pack, is a commonly reported concern.

If any of these red flags appear, do not inject. Keep the pen, carton, the pharmacy bill and the courier packaging together — these are what CDSCO and Zydus will ask for if you report it. You can also upload a photo at /check for a non-binding visible-checks review.

What to do next

If your Semaglyn pen shows one or more red flags above, the calm path is:

1. Stop and don't inject. Keep the pen sealed and refrigerated if possible.
2. Go back to the pharmacist who sold it. A legitimate Apollo, Tata 1mg, Pharmeasy or Netmeds pharmacist will give you the purchase invoice, the batch number, and usually escalate to their supplier. Insist on a written record.
3. Report to CDSCO. The Central Drugs Standard Control Organisation runs an online complaint portal for suspected spurious or substandard drugs. Quote the brand (Semaglyn), batch number, Mfg/Exp dates, pharmacy name and bill number.
4. Contact Zydus Lifesciences through the customer-care number printed on the carton. They can confirm whether a batch number was ever released.
5. Talk to your prescriber. Share photos of the pen and carton, and consult your doctor before resuming any GLP-1 therapy — including whether a switch to a different verified semaglutide brand (Wegovy India, Obeda) is appropriate for you.
