How you get itPrescription only

Dapagliflozin works the same way as empagliflozin — removing surplus glucose through the urine — and is used across the same three areas: type 2 diabetes, heart failure and chronic kidney disease. The same two safety points apply.

What it is used for

Type 2 diabetes, chronic heart failure and chronic kidney disease. In heart failure and kidney disease it is prescribed whether or not you have diabetes.

Modest weight loss and a small blood pressure reduction are common alongside its main effect.

How to take it

Once daily, with or without food. Morning suits most people since it increases urine output.

Keep your fluid intake up, especially in hot weather. If you also take a diuretic, be alert to dizziness on standing.

Sick day rules and DKA

Pause dapagliflozin during dehydrating illness — vomiting, diarrhoea, fever, or not eating and drinking normally — restarting after 24 to 48 hours of normal intake. It is also stopped before planned surgery and during prolonged fasting. Ask for a sick day rules card.

Diabetic ketoacidosis can occur with normal or only mildly raised blood glucose on SGLT2 inhibitors. Get urgent help for nausea and vomiting, stomach pain, excessive thirst, fast or deep breathing, confusion, unusual tiredness or sweet-smelling breath — and say that you take an SGLT2 inhibitor.

Infections and other effects

Genital thrush and urinary tract infections are considerably more common because of the sugar in the urine. Wash and dry the area daily, and come to us early rather than waiting it out.

Seek urgent help for genital or perineal pain, redness or swelling with fever or feeling unwell — a rare but serious infection needing immediate treatment.

Not used in pregnancy or breastfeeding. Tell your team if you are planning a pregnancy.

Always read the label. This page is general information, not advice for your situation. Doses, warnings and interactions differ between products and between people. Check the leaflet inside your medicine, and ask our pharmacist if anything is unclear — that conversation is free and takes two minutes.

Frequently asked questions

What is the difference between dapagliflozin and empagliflozin?
They are in the same class and work the same way. Which you are prescribed depends on the licensed indication for your condition and prescriber choice.
Should I stop dapagliflozin when I am unwell?
Yes, temporarily, during vomiting, diarrhoea or fever, restarting after 24 to 48 hours of normal eating and drinking.
Does dapagliflozin cause weight loss?
Modest weight loss is common, since glucose is passed out in the urine. It is not a weight loss medicine.
Why do I keep getting thrush on dapagliflozin?
Sugar in the urine encourages genital thrush. Daily washing and drying helps, and we can treat it — come and see us early.
