DPP-4 Inhibitor (Antidiabetic)
Last reviewed June 2026
Who is this for?
Linagliptin (sold as Trajenta in Nigeria) is a diabetes medicine that works by helping your body produce more insulin after meals and reducing the amount of sugar your liver releases into your blood.
Inhibits dipeptidyl peptidase-4 (DPP-4), preventing degradation of incretin hormones (GLP-1 and GIP) and thereby increasing insulin secretion and reducing glucagon release in response to meals.
Prescription Required
You need a doctor's prescription to buy this drug.
Explore this drug
Take one 5mg tablet once a day, at any time that suits you. You can take it with or without food. Try to take it at the same time every day so you don't forget.
If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, just skip the missed one and continue as normal. Do not take two tablets at once to make up for the missed dose.
Always buy Trajenta from a licensed pharmacy — do not buy diabetes medicine from roadside sellers or unverified sources. This drug does not replace diet and exercise; continue eating well and staying active. Do not share your diabetes medication with anyone, even if they have similar symptoms.
If you are taking insulin or other diabetes medicines like glimepiride, your blood sugar may drop too low — your doctor may need to adjust the dose. Rifampicin (used for TB treatment) can reduce how well linagliptin works. Always tell your doctor about all medicines you are taking.
Check your specific combination
Is it safe to take Linagliptin with your other drugs?

Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be very hot so avoid leaving it in your car or near windows. Keep the tablets in their original pack and away from children.
