How to spot counterfeit Januvia — for South Korea
Counterfeit medication is a real and serious problem in unregulated supply chains. Januvia (Sitagliptin), particularly when bought online from unverified sources, is among the most counterfeited prescription drugs in some markets. Knowing what genuine Januvia looks like and where the red flags lie is part of self-protection at 25mg, 50mg, 100mg.
South Korea context
Counterfeit prescription medication is a real concern in unregulated channels in South Korea, particularly for high-demand brands. Genuine Januvia dispensed through licensed South Korean pharmacies under MFDS (Ministry of Food and Drug Safety) oversight carries vanishingly small counterfeit risk; suspect packaging, missing leaflets or implausibly low KRW pricing online are warning signs to verify before taking.

Visual and packaging checks
Genuine Januvia arrives in original sealed packaging from Merck (MSD), with intact tamper-evident features, an in-box patient leaflet matching the local language, and tablets or capsules with consistent shape, colour and markings as described in the prescribing information. Inconsistent typography, missing or low-quality printing, broken seals or absent leaflet are all warning signs.
Supply chain red flags
The biggest single predictor of counterfeit risk is the supplier. Licensed local pharmacies and well-known regulated online channels carry vanishingly small counterfeit risk. Unverified online sellers, parallel-import websites with no contactable pharmacist, "no prescription needed" offers at suspicious prices, and shipping from countries unrelated to the buyer's jurisdiction are major red flags. According to the prescribing information, only legitimate channels guarantee that Sitagliptin matches the labelled dose at 25mg, 50mg, 100mg.
