Have a sick day plan

If you are unwell, stop taking Jardiamet. Taking Jardiamet when you are unwell increases your risk of high ketones levels, which can cause a serious but rare side effect called diabetic ketoacidosis (DKA). Only restart your Jardiamet when you are well AND 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 at either your GP clinic, after hours medical centre or hospital to check your ketone levels.

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 diabetic 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 2 times a day and men should wash their penis, foreskin and groin area at least once per day.

Prepare before an operation or a procedure

If you are going to have an operation or a procedure such as a colonoscopy, ask your healthcare team when you should stop and restart your Jardiamet. You may need to stop your Jardiamet 2 or 3 days before the operation.

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

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