Acarbose for diabetes

About acarbose

Insulin is a hormone that 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, or if it does not use the insulin it makes effectively, this results in the condition called diabetes (diabetes mellitus).

People with diabetes need treatment to control the amount of sugar (glucose) 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 acarbose are given alongside the changes in diet.

Acarbose works by slowing down the digestion and absorption of carbohydrates from your digestive system. This helps to reduce the high blood sugar levels which occur after eating meals.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking acarbose it is important that your doctor knows:

• Se você está grávida, tentando ter um bebê ou amamentando.

• If you have any problems with the way your liver works or with the way your kidneys work.

• If you have a hernia or if you have recently had surgery on your tummy (abdomen).

• If you have inflammatory bowel disease.

• Se você estiver tomando outros medicamentos. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

• Se você já teve uma reação alérgica a um medicamento.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about acarbose tablets and will provide you with a full list of the side-effects which you may experience from taking them.

• Take acarbose exactly as your doctor tells you to. There are two strengths of tablet - 50 mg and 100 mg. It is usual to be started on one 50 mg tablet a day to begin with. Your dose will gradually be increased, as needed, up to a maximum dose of 200 mg three times daily. Increasing your dose gradually like this will help to minimise the risk of side-effects.

• Swallow the tablet with a drink of water at the beginning of a meal, or if you prefer, you can chew the tablet with your first mouthful of food.

• If you forget to take a dose, do not worry, just take your next dose when it is due. Do not take two doses together to make up for a forgotten dose, and do not take the tablets between meals.
  

• 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.

• Do not drink alcohol as it can affect the control of your blood sugar. Ask your doctor if you need further advice about this.

• If you are due to have an operation or dental treatment, you should tell the person carrying out the treatment that you have diabetes and that you are taking acarbose.

• If you get unusually thirsty, pass urine more frequently, and feel very tired, then let your doctor know. These are signs that there is too much sugar in your blood and your treatment may need adjusting.

• Make sure you know what it feels like if your blood sugar is too 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 a feeling that your heart is pounding (palpitations), and feeling dizzy. If these happen you should eat or drink something containing glucose straightaway. Your pharmacist will be able to recommend a suitable glucose preparation for you.

• 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. You may be advised to check your blood or urine glucose levels before you travel and to have a snack with you on long journeys.

• Treatment for diabetes is usually lifelong. Continue to take the tablets unless you are advised otherwise by your doctor.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with acarbose. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
