Glibenclamide for diabetes

About glibenclamide

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, 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 glibenclamide are given alongside the changes in diet.

Glibenclamide works by increasing the amount of insulin that your pancreas produces. This helps to reduce the amount of sugar in your blood.

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 glibenclamide it is important that your doctor knows:

• Om du är gravid, försöker bli gravid eller ammar.

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

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

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

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

• Take glibenclamide exactly as your doctor tells you to. The usual starting dose for an adult is 5 mg daily. It is prescribed as a single dose to be taken with, or immediately after, breakfast.

• The dose for a child will vary depending on their body weight and may be needed more than once per day; follow your doctor's instructions carefully.

• If you (or your child) have been given oral liquid medicine, take care to measure the correct amount using the oral syringe and adaptor provided. Follow the printed instructions in the manufacturer's leaflet.

• If you are giving the oral liquid medicine to a baby, it should be given around 15 minutes before a milk feed.

• If you forget to take a dose at the usual time, take it with your next meal. If you do not remember until the following day, skip the missed dose. Do not take two doses on the same day to make up for a forgotten dose.

• It is important that you keep your regular doctor's and clinic appointments. This is so that your progress can be monitored. You will 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 (glucose) in your blood 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.

• Make sure you know what it feels like if your blood sugar drops 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.

• Low blood sugar (hypoglycaemia) can occur if you miss a meal, if you exercise more than usual, if you are ill, or if you drink alcohol.

• 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 a driver you should take special care, as your ability to concentrate may be affected if your diabetes is not well controlled. You may be advised to check your blood sugar levels before you travel and to have a snack with you on long journeys.

• Drivers in the UK may need to inform the Driver and Vehicle Licensing Agency (DVLA) if they experience an episode of severe hypoglycaemia or experience a 'hypo' whilst driving. Ask your doctor for advice. Drivers in other countries should contact the relevant vehicle licensing agency.

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

• 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 levels more regularly.

• 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 give them a list of the medicines you are taking.

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

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

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 glibenclamide. 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.

Om du upplever några andra symtom som du tror kan bero på tabletterna, tala med din läkare eller apotekare för vidare råd.

• Förvara alla läkemedel utom räckhåll och synhåll för barn.

• Förvara på en sval, torr plats, borta från direkt värme och ljus.

• The oral liquid medicine should not be used for more than 30 days after first opening. It's a good idea to write on the label the date you first opened the bottle.
