About nizatidine

Nizatidine belongs to a group of medicines that reduce the amount of acid produced by the cells in the lining of the stomach. They are called 'histamine H2-receptor antagonists', but are commonly also called Bloqueadores H2.

Nizatidine can be helpful in the treatment of conditions caused by too much acid being produced in the stomach. These conditions include stomach ulcers (gastric ulcers), ulcers of the upper part of the intestine (úlceras duodenais), and acid reflux or heartburn (gastro-oesophageal reflux disease). Nizatidine can also be prescribed to treat ulceration of the stomach which has been caused by anti-inflamatórios não esteroides (AINEs). Although nizatidine can be helpful in the treatment of these conditions, in practice other medicines are usually tried first.

Acid is produced naturally in your stomach to help to digest food. Excessive amounts of acid can irritate the lining of your stomach, causing inflammation, ulcers and other conditions. Nizatidine works by reducing the amount of acid produced by your stomach. This helps to relieve symptoms and assist the healing process where damage has already occurred.

To make sure this is the right treatment for you, before you start taking nizatidine it is important that your doctor or pharmacist knows:

• Se você está grávida ou amamentando.

• If you have any of the following symptoms: difficulty swallowing, loss of blood, weight loss, or if you are being sick.

• Se você tiver algum problema com o funcionamento do seu fígado ou com o funcionamento dos seus rins.

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

• 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.

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

• Take nizatidine exactly as your doctor tells you to. There are two different strengths of capsule available - 150 mg and 300 mg. You may be prescribed nizatidine to take twice a day, in the morning and evening, or just once a day in the evening. Your doctor will tell you what dose is right for you and the directions will be on the label of the pack to remind you about what was said to you.

• You can take nizatidine before or after meals.

• Se você esquecer de tomar uma dose no horário habitual, pode tomá-la quando se lembrar (a menos que esteja quase na hora da próxima dose, nesse caso, pule a dose esquecida). Não tome duas doses juntas para compensar uma dose esquecida.

• A course of treatment can vary in length depending upon the reason why you are taking nizatidine. You could be asked to take it for a week or two, or for several months. Keep any appointments that you have booked with your doctor so that your progress can be checked.

• Some people say that certain foods make their symptoms worse. Foods and drinks that have been suspected of this include peppermint, tomatoes, chocolate, spicy foods, hot drinks, coffee, and alcoholic drinks. If it seems that a food is aggravating your symptoms, try avoiding it for a while to see if your symptoms improve. Also, try avoiding eating large meals, as these can make your symptoms worse too.

• If you are overweight, this puts extra pressure on your stomach and encourages the symptoms of acid reflux. Losing some weight and eating a healthy balanced diet may help you.

• Fumar aumenta a quantidade de ácido produzido pelo estômago e pode piorar seus sintomas. Se você é fumante, fale com seu médico ou farmacêutico sobre como parar de fumar.

• Se você comprar qualquer medicamento 'sem receita', sempre verifique com um farmacêutico se é seguro tomá-los junto com seus outros medicamentos.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the ones associated with nizatidine, although these are generally mild and do not last long. 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.

If you experience any other symptoms which you think may be due to nizatidine, speak with your doctor or pharmacist for further advice.

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

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