Sitagliptina para diabetes

About sitagliptin

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

Pessoas com diabetes need treatment to control the amount of sugar (glucose) in their blood. This is because good control of blood glucose 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 sitagliptin are given alongside the changes in diet.

Sitagliptin works in part by increasing the amount of insulin produced by your body. It also reduces the amount of a substance called glucagon being produced by your pancreas. Glucagon causes your liver to produce more sugar, so by reducing the amount of glucagon in your body, this also helps to reduce the levels of glucose 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 sitagliptin it is important that your doctor knows:

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

• Se você tiver algum problema com o funcionamento dos seus rins.

• 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 sitagliptin tablets and will provide you with a full list of the side-effects which you may experience from taking them.

• Take sitagliptin tablets exactly as your doctor tells you to. The usual dose is one 100 mg tablet a day. (You may be prescribed a lower strength of tablet if you have a problem with the way your kidneys work.) You can generally take the tablet at a time of day to suit you, but it is best to take your doses at the same time of day each day. You can take sitagliptin before or after a meal.

• If you have been prescribed a combination tablet of sitagliptin with metformin (brand Janumet®) you should take one tablet twice a day, after meals.

• If you forget to take a dose, take it as soon as you remember (unless it is nearly time for your next dose, in which case leave out the missed dose). Do not take two doses together to make up for a forgotten dose.
  

• It is important that you keep your regular doctor's and clinic appointments. This is so 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 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.

• Não consuma álcool, pois isso pode afetar o controle do seu açúcar no sangue. Pergunte ao seu médico se precisar de mais conselhos sobre isso.

• Se você é motorista, deve ter cuidado especial, pois sua capacidade de concentração pode ser afetada se o seu diabetes não estiver bem controlado. Pode ser aconselhado a verificar seus níveis de açúcar no sangue antes de viajar e a ter um lanche com você em viagens longas.

• Se você recebeu conselhos do seu médico sobre mudanças na sua dieta, parar de fumar ou fazer exercícios regularmente, é importante seguir os conselhos que lhe foram dados.

• Consulte o seu médico antes de iniciar qualquer novo exercício físico, pois isso afetará os seus níveis de açúcar no sangue e você pode precisar verificar seus níveis de sangue ou urina com mais regularidade.

• Make sure you know what it feels like if your blood sugar is low. This is known as hypoglycaemia, or a 'hypo'. Although sitagliptin is unlikely to cause low blood sugar, other medicines that you are taking for diabetes alongside it may. 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 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 sitagliptin.

• If you get unusually thirsty, pass urine more frequently, and 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.

• Treatment for diabetes is usually lifelong. Continue to take sitagliptin 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 sitagliptin. 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.

Se você sentir quaisquer outros sintomas que acha que podem ser causados pelos comprimidos, fale com seu médico ou farmacêutico para mais orientações.

• Mantenha todos os medicamentos fora do alcance e da vista das crianças.

• Armazene em local fresco e seco, longe de calor e luz diretos.
