About nateglinide

Insulin is a hormone which is made naturally in your body, in the pancreas. It helps to control the levels of sugar in your blood. If your body does not make enough insulin to meet its needs, or if it does not use the insulin it makes effectively, this results in the condition called diabetes mellitus (sugar diabetes).

People with diabetes need treatment to control the amount of glucose (sugar) in their blood. This is because good control of blood sugar levels reduces the risk of complications later on. Some people can control the sugar in their blood by making changes to the food they eat but, for other people, medicines like nateglinide are given alongside the changes in diet.

Nateglinide works by encouraging your pancreas to produce more insulin which then controls your blood sugar levels. It is given alongside another antidiabetic medicine called metformin.

Before taking nateglinide

Before taking nateglinide make sure your doctor or pharmacist knows:

• If you are under 18 or over 75 years of age.
• If you are pregnant, trying for a baby or breast-feeding.
• If you have liver problems.
• If you have a severe illness or infection.
• If you have ever had an allergic reaction to this or to any other medicine.
• If you are taking any other medicines, including those available to buy without a prescription, herbal and complementary medicines.

How to take nateglinide

• Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
• Take nateglinide exactly as your doctor has told you. It is best to take it just before a main meal, but you can take it up to 30 minutes before.
• If you forget to take a dose, do not worry, just carry on as normal at the next mealtime. Do not take two doses together to make up for a forgotten dose.

Getting the most from your treatment

• It is important that you keep your regular doctor's and clinic appointments. This is so your progress can be monitored. You are likely to need regular check-ups with an eye clinic and a foot clinic as well as with your doctor and diabetes clinic.
• Your doctor may recommend that you test for sugar in your blood or urine regularly to check that your diabetes is being controlled. Your doctor or diabetes nurse will show you how to do this.
• If you have been given advice by your doctor about changes to your diet, stopping smoking or taking regular exercise, it is important for you to follow the advice you have been given.
• Check with your doctor before taking up any new physical exercise, as this will have an effect on your blood sugar levels and you may need to check your blood or urine levels more regularly.
• Drinking alcohol is not recommended with nateglinide, but, if you do have a drink, keep to the recommended alcohol limits. Taking nateglinide and alcohol will affect the control of your blood sugar.
• If you are due to have an operation or dental treatment, you should tell the person carrying out the treatment that you are diabetic and taking nateglinide.
• If you get unusually thirsty, pass urine more frequently, and feel very tired, then let your doctor know. Your dose of nateglinide may need adjusting.
• If you are a driver you should take special care as your ability to concentrate may be affected if your diabetes is not well-controlled. Make sure you know what it feels like if your blood sugar is low. This is known as hypoglycaemia or a 'hypo'. The first signs of hypoglycaemia are: feeling shaky or anxious, sweating, looking pale, feeling hungry, having palpitations (a feeling that your heart is pounding), and feeling dizzy. If these happen you should eat or drink something containing sugar or have a snack straightaway. It is advisable to check your blood or urine glucose levels before you travel on long journeys and have a snack with you.
