About acarbose

Diabetes mellitus (in adults)

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.

Before taking acarbose

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:

  • Si está embarazada, esperando un bebé o en período de lactancia.

  • Si tiene algún problema con el funcionamiento del hígado o de los riñones.

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

  • If you have inflammatory bowel disease.

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como medicamentos a base de plantas y complementarios.

  • Si alguna vez ha tenido una reacción alérgica a un medicamento.

How to take acarbose

  • 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.

Aproveche al máximo su tratamiento

  • Es importante que acuda regularmente a las citas médicas y clínicas. Así podremos controlar su evolución. Es probable que necesite revisiones periódicas en una clínica oftalmológica y podológica, así como con su médico y la clínica de diabetes.

  • 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.

  • Si su médico le ha aconsejado hacer cambios en la dieta, dejar de fumar o hacer ejercicio con regularidad, es importante que siga sus consejos.

  • Consulte a su médico antes de realizar cualquier ejercicio físico nuevo, ya que tendrá un efecto sobre sus niveles de azúcar en sangre y es posible que deba comprobar sus niveles en sangre u orina con mayor regularidad.

  • 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.

  • Si compra algún medicamento, compruebe con un farmacéutico que es adecuado para usted.
