Quinine for malaria

About quinine for malaria

Malária is a very serious infection which you can develop from a bite from an infected mosquito. The most common symptom is high temperature (fever) and a flu-like illness. Malaria can occur even up to a year after travelling in an area in which there is malaria. Prompt treatment for malaria is essential. If you feel unwell and have recently visited an area in which there is malaria, you should seek imediato aconselhamento médico, mesmo que você tenha tomado sua medicação antimalárica corretamente.

Malaria is caused by a parasite called plasmodium. The parasite lives inside the stomach of an infected female mosquito and is passed to humans from a mosquito bite. There are four types of plasmodium that cause malaria. Of the four, Plasmodium falciparum is usually the most serious, so this type of malaria is likely to be treated in hospital.

Quinine is also used to treat night-time leg cramps. For information about this please see the medicine leaflet Quinine for leg cramps.

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 quinine it is important that your doctor knows:

• Se você está grávida ou amamentando.

• If you have any problems with your eyes, or with your hearing.

• If you have a heart condition, such as an irregular heart rhythm.

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

• If you have blood in your urine.

• If you have been told you have an imbalance of salt levels in your blood.

• Se você tem uma condição que causa fraqueza muscular, chamada miastenia gravis.

• If you have glucose 6-phosphate dehydrogenase deficiency. This is a genetic disorder where there is a lack of an enzyme often known as G6PD. People with this disorder have problems after eating foods such as fava beans.

• 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.

• If you have ever had an allergic reaction to a medicine, or if you have had a bad reaction to quinine in tonic water or any other soft drink.
  

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

• Take quinine exactly as your doctor tells you to. If you are being treated in hospital, your nurse will tell you when your tablets are due. If you are being treated at home, your doctor or pharmacist will tell you how many tablets to take for each dose, and when the doses should be taken. Your dose will also be printed on the label of the pack to remind you about what the doctor said to you. Space the doses evenly throughout the day and continue to take the tablets until the course is finished, unless your doctor tells you to stop sooner. It is important you do this even if you feel better. It is to make sure that all of the parasite has been removed from your body.

• Swallow your doses with a drink of water. You can take quinine tablets either before or after meals.

• Se você esquecer de tomar uma dose, tome-a assim que se lembrar. Tente tomar o número correto de doses a cada dia, mas não tome duas doses ao mesmo tempo para compensar uma dose esquecida.

• If you are being treated from home, make sure you keep your regular appointments with your doctor. This is so your doctor can check on your progress.

• Your doctor will discuss with you the possibility of unwanted side-effects of the treatment. It is important that you let your doctor know, antes you take your next dose, if you experience any of the following: impaired hearing, ringing noises in your ear, headaches, feeling sick (nausea), or any problems with your eyesight.

• Quinine is present in drinks such as tonic water and bitter lemon. It is probably best to avoid these drinks while you are taking quinine tablets.

• Never take more than the prescribed dose. Taking too much quinine can cause serious problems. Also, quinine is dangerous if it is taken by a child, so keep the tablets away from children. If you suspect that someone has taken an overdose of quinine or has swallowed some by accident, you must contact a doctor imediatamente. Alternatively, go to the accident and emergency department of a local hospital. Do not delay. Take the container with you, even if it is empty. This is so the doctor knows what has been taken.

• If you buy any medicines, always check with a pharmacist that they are suitable to take with your other medicines. This is because some medicines (such as cimetidine which is taken for heartburn) can interfere with quinine and increase the risk of serious side-effects.

• If you are being treated for diabetes, quinine can lower the level of sugar in your blood. Your doctor will be able to advise you about this.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the side-effects associated with quinine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. Although unwanted effects often improve as your body adjusts to a new medicine, serious side-effects do still sometimes occur. Contact your doctor for advice as soon as possible if you experience any of the following:

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

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

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