Empagliflozin is used to treat type 2 diabetes and protect your kidneys and heart. Read more about type 2 diabetes. 

Empagliflozin lowers your blood glucose and blood pressure by helping your kidneys get rid of glucose, salt and fluid when you pass urine (pee/mimi). Empagliflozin has other benefits such as weight loss, helping your kidneys work better and lowering your chance of having a heart attack or stroke. It may also help you to live longer.

Empagliflozin can be used alone, or with other diabetes medicines (such as metformin), to help manage your glucose levels along with healthy eating and regular exercise. 

Note: Empagliflozin is also available as a combined tablet with metformin which is called Jardiamet. 

  • In Aotearoa New Zealand empagliflozin is available as tablets (10mg and 25mg). 
  • The usual starting dose is 1 tablet (10mg) once a day. 
  • Depending on your blood glucose levels, your doctor may increase your dose to 25mg once a day. 
  • Always take your empagliflozin exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much to take, how often to take it and any special instructions.

  • Timing: Take empagliflozin once a day, at the same time each day. Swallow your tablets with a drink of water. You can take empagliflozin with or without food. 
  • Drink enough water so you don't get thirsty: When you start taking empagliflozin, you may pee more but this gets better over a few weeks. If you’ve been told to limit how much you drink, talk to your healthcare team.
  • Avoid or limit alcohol while you are taking empagliflozin: It may affect your blood glucose control and increase your risk of side effects. Drinking alcohol very often or drinking a lot of alcohol over a short time (binge drinking) can affect your diabetes and lead to high ketone levels. This can cause a serious but rare side effect called ketoacidosis
  • Missed dose: If you forget your dose, take it as soon as you remember that day unless it is 12 hours or less until your next dose is due. If that's the case, take your next dose at the usual time and skip the forgotten dose. 
  • Don't run out of tablets: Empagliflozin works best when taken every day. See your healthcare team every 3 months for a new prescription.

Here are some things to know when you're taking empagliflozin. Other things may be important as well, so ask your healthcare provider what you should know about.

Have a sick day plan

If you're unwell, stop taking empagliflozin. Taking empagliflozin when you are unwell increases your risk of high ketone levels, which can cause a serious but rare side effect called diabetic ketoacidosis (DKA). Only restart your empagliflozin when you are well AND you're eating and drinking normally.

If you have nausea (feeling sick), vomiting (being sick) or tummy pain, you need to have a finger prick blood test immediately to check your ketone levels. This can be done at your GP clinic, after hours medical centre or hospital.

Tell your healthcare team before making any big changes to your diet

If you start eating less or go on a keto (low carbohydrate) diet or are fasting, this may increase your risk of ketoacidosis.

Keep your genitals clean

Because you will pee more and have more glucose in your urine, you have a higher risk of getting thrush or groin infections.

Regular washing helps prevent this. Women should wash their groin and vulval area twice a day and men should wash their penis, foreskin and groin area at least once a day.

Prepare before an operation or a procedure

If you are going to have an operation or a procedure where you will need to stop eating for 12 hours or more such as a colonoscopy or dental surgery, ask your healthcare team when you should stop and restart your empagliflozin. You may need to stop your empagliflozin 3 days before the operation or procedure.

Fasting during Ramadan

If you are fasting during Ramadan and are still getting enough carbohydrates, you can keep taking empagliflozin. It's important to talk to your healthcare provider about getting enough carbohydrates and drinking plenty of water while taking empagliflozin. It's not recommended to start empagliflozin as a new medicine immediately before or during Ramadan.

Are you pregnant, trying for a baby or breastfeeding?

It is important to talk to your GP or nurse as soon as possible if you are trying to get pregnant, are pregnant or breastfeeding. You may need to change to another diabetes medicine.

Tell your healthcare team if you are taking any other medicines

Empagliflozin may interact with some medicines and herbal supplements, so check with your doctor or pharmacist before starting empagliflozin and before starting any new medicines.

Exercising and diet

It's important to keep up your healthy diet and exercise while you're taking empagliflozin. Empagliflozin works best when used in combination with good nutrition and regular exercise. 

It's a good idea to cut down on foods with added sugar if you have diabetes. However, ask your healthcare provider for advice before starting a low-calorie, reduced carbohydrate or keto diet. Having too few carbohydrates in your diet while you are taking empagliflozin may increase your risk of ketoacidosis.

Note: You should avoid a low carbohydrate (ketogenic or keto) diet while you are taking empagliflozin. This may increase your risk of ketoacidosis. 

Marathon or long distance runners

Being dehydrated and not eating enough carbohydrates can lead to high ketone levels, which can cause a serious but rare side effect called ketoacidosisIf you are going to run a long distance or marathon while you are taking empagliflozin, it's important to let your healthcare provider know. You may need to stop empagliflozin the day before the marathon and restart 24 hours or so afterwards when you are well hydrated and eating normally. 

Blood glucose testing with a glucometer 

Empagliflozin won't cause low blood glucose levels (hypoglycaemia) unless you're also taking insulin and/or sulfonylureas (eg, glipizide or gliclazide tablets). So if you are also taking insulin and/or sulfonylureas, you need to check your glucose levels regularly with a glucometer to make sure they are safe.

If you're not on insulin or sulfonylureas, you may still choose to check your glucose levels to see the effects of empagliflozin. It's also important to check your HbA1c 3 months after starting empagliflozin.

You may need a blood glucose test and a ketone test if you are unwell with vomiting (being sick) or diarrhoea (runny poo). Ask your healthcare provider for advice. Read more about diabetes blood glucose testing and diabetes sick day plan.

Like all medicines, empagliflozin can cause side effects, although not everyone gets them. Please note, empagliflozin does not cause weight gain and usually helps you lose weight.
