How you get itPrescription only

Linagliptin works the same way as sitagliptin, with one practical difference that matters a lot in general practice: it is cleared mainly through the gut rather than the kidneys, so it usually needs no dose adjustment in kidney impairment. That is often why it is the gliptin chosen.

How to take it

One 5mg tablet once daily, with or without food, at the same time each day. Swallow whole.

It can be taken alone or alongside metformin, a sulfonylurea, an SGLT2 inhibitor or insulin.

If you miss a dose, take it when you remember unless the next is nearly due — never double up.

Kidney function

Unlike most other diabetes tablets, linagliptin does not usually need its dose reducing when kidney function is impaired, because it is largely eliminated through the bowel. That makes it a common choice in older patients and in chronic kidney disease.

Your kidney function will still be monitored as part of routine diabetes care.

Side effects

Generally very well tolerated. Cold-like symptoms, cough, and raised pancreatic enzymes are among the reported effects.

Seek urgent medical help for severe persistent stomach pain, possibly spreading to the back — a rare sign of pancreatitis. Stop taking it and get assessed.

Also report blistering of the skin, severe joint pain, or swelling of the face, lips or throat.

Hypos are unlikely with linagliptin alone but possible when combined with a sulfonylurea or insulin.

It is not used in pregnancy — tell your diabetes team if you are planning one.

Frequently asked questions

Why was I given linagliptin rather than sitagliptin?
Linagliptin is cleared mainly through the bowel rather than the kidneys, so it usually needs no dose reduction in kidney impairment. That is often the reason.
Does linagliptin cause weight gain or hypos?
It is generally weight-neutral and rarely causes hypos alone. Hypos become possible when combined with a sulfonylurea or insulin.
When should I take linagliptin?
One tablet once daily, with or without food, at the same time each day.
What should I watch for on linagliptin?
Severe persistent stomach pain spreading to the back needs urgent assessment. Also report blistering skin or severe joint pain.
