Tolbutamida

About tolbutamide

Insulin is a hormone which is made naturally in your body, in the pancreas. It helps to control the levels of sugar (glucose) 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 (diabetes mellitus).

People with diabetes need treatment to control the amount of 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 tolbutamide are given alongside the changes in diet.

Tolbutamide works by increasing the amount of insulin that your pancreas produces. It can be given on its own or alongside other antidiabetic medicines or insulin.

Before taking tolbutamide

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

• Si estás embarazada o amamantando.

• Si tienes algún problema con el funcionamiento de tu hígado, o si tienes algún problema con el funcionamiento de tus riñones.

• If you have been told you have either porphyria or glucose-6-phosphate dehydrogenase (G6PD) deficiency. These are both rare inherited disorders.

• Si está tomando otros medicamentos. Esto incluye cualquier medicamento que se pueda comprar sin receta, así como medicamentos herbales y complementarios.

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

How to take tolbutamide

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

• Take tolbutamide exactly as your doctor tells you to. It is usually prescribed as a once-daily dose of 1-3 tablets (500 mg strength) with breakfast, although some people are asked to take the tablets in divided doses over the day. Your doctor or pharmacist will tell you which is right for you, and this information will also be printed on the label of the pack of tablets to remind you about what the doctor said.

• If you are asked to take tolbutamide as a once-daily dose, take the tablets during your breakfast or immediately afterwards. If you are asked to take several doses of tolbutamide during a day, then take each of the doses during a mealtime or immediately afterwards. Swallow the tablets with a drink of water.

• If you forget to take a dose, take it at the next mealtime. Try to take the correct number of tablets each day, but do not take two doses together to make up for a missed dose.

• 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.

• Su médico puede recomendarle que se realice pruebas de azúcar (glucosa) en su sangre regularmente para verificar que su diabetes esté controlada. Su médico o enfermero de diabetes le mostrarán cómo hacerlo.

• Si tu médico te ha dado consejos sobre cambios en tu dieta, dejar de fumar o hacer ejercicio regularmente, es importante que sigas los consejos que te han dado.

• 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 this happens, eat something containing sugar, such as dextrose tablets, or sugary sweets or drinks (non-diet), and then follow this up with a snack such as a sandwich or a banana.

• Hypoglycaemia can occur in particular if you miss a meal, if you exercise more than usual, if you are ill, or if you drink a lot of alcohol.

• Si eres conductor, debes tener especial cuidado, ya que tu capacidad de concentración puede verse afectada si tu diabetes no está bien controlada. Se te puede aconsejar que verifiques tus niveles de azúcar en sangre antes de viajar y que lleves un refrigerio contigo en viajes largos.

• Los conductores en el Reino Unido pueden necesitar informar a la Agencia de Licencias de Conducir y Vehículos (DVLA) si experimentan un episodio de hipoglucemia severa o sufren una 'hipo' mientras conducen. Consulte a su médico para obtener asesoramiento. Los conductores en otros países deben ponerse en contacto con la agencia de licencias de vehículos correspondiente.

• Consulte a su médico antes de comenzar cualquier ejercicio físico nuevo, ya que esto afectará sus niveles de azúcar en la sangre y es posible que deba controlar sus niveles de sangre con más frecuencia.

• Drinking alcohol is not advisable with tolbutamide. If you do have a drink, keep well within the recommended alcohol limits, as alcohol will affect the control of your blood sugar.

• If you get unusually thirsty, pass urine more frequently, and feel very tired then let your doctor know. Your dose of tolbutamide may need adjusting.

• 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 tolbutamide.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because some medicines may interfere with tolbutamide.

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