About hydroxychloroquine
Art des Medikaments | Disease-modifying antirheumatic drug (DMARD) |
Verwendet für | Rheumatoid arthritis; juvenile arthritis; systemic and discoid lupus erythematosus; and skin conditions caused or aggravated by sunlight |
Auch genannt | Hydroxychloroquine sulfate; Quinoric® |
Verfügbar als | Tabletten |
Hydroxychloroquine is used to treat a number of different inflammatory conditions, including rheumatoide Arthritis, Juvenile Arthritis, and lupus erythematosus(systemischer Lupus erythematodes (SLE) and discoid erythematosus). These are all autoimmune diseases. This means that your immune system, which normally protects your body from infections, mistakenly attacks itself. This causes pain and damage to parts of your body, particularly your joints or skin. Hydroxychloroquine suppresses the immune reaction, and this helps to reduce the damage caused.
Before taking hydroxychloroquine
Zurück zum InhaltSome 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 hydroxychloroquine it is important that your doctor or pharmacist knows:
Wenn Sie schwanger sind, versuchen, schwanger zu werden oder stillen.
If you have any problems with your kidneys or liver.
If you have any problems with your heart or your blood.
Wenn Sie Epilepsie haben.
If you have problems with your eyes or eyesight, except for long- or short-sightedness.
If you have a problem with your stomach or intestines (a gastrointestinal problem).
If you have a skin disorder called psoriasis, or a condition causing muscle weakness (called myasthenia gravis), as these conditions can be made worse by hydroxychloroquine.
If you know you have glucose-6-phosphate dehydrogenase (G6PD) deficiency. This is an inherited disorder which causes problems after eating some foods, such as fava beans.
Wenn Sie eine seltene erbliche Bluterkrankung namens Porphyrie haben.
Wenn Sie andere Medikamente einnehmen. Dazu gehören alle Medikamente, die Sie einnehmen und die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Medikamente.
Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

How to take hydroxychloroquine
Zurück zum InhaltBefore you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about treatment with hydroxychloroquine and a full list of side-effects which you may experience from taking it.
It is important that you take hydroxychloroquine exactly as your doctor tells you to. You may be prescribed one or two tablets to take each day. Your doctor or pharmacist will tell you which is right for you. Your dose will also be printed on the label of the pack to remind you.
Take the tablets at a mealtime, or alternatively swallow them with a glass of milk. This will help to stop you feeling queasy afterwards, as hydroxychloroquine may irritate your stomach. Do not crush or chew the tablets.
If you take a medicine for indigestion (such as an antacid), do not take it within the four hours before you take hydroxychloroquine, or within the four hours afterwards. This is because antacids interfere with the way hydroxychloroquine is absorbed by your body, making it less effective.
If you forget to take a dose, take it as soon as you remember. However, if when you remember, it is nearly time for your next dose then leave out the forgotten dose. Do not take two doses together to make up for a missed dose.
Das Beste aus Ihrer Behandlung herausholen
Zurück zum InhaltTry to keep your regular appointments with your doctor. This is so your doctor can check on your progress. Your doctor is likely to check your vision before you start this treatment, and advise that you have an eye test once every year. This is because hydroxychloroquine can affect your eyesight when taken over a long period of time. If you notice any changes in your eyesight (such as your vision becoming blurred), you should inform your doctor as soon as possible.
If you have been prescribed hydroxychloroquine for skin problems worsened by sunlight, you will be advised to take it only during the periods when you are exposed to bright sunlight.
For conditions other than skin problems caused by sunlight, you may need to take hydroxychloroquine for several weeks before you start to notice an improvement in your condition. It can take several months before you feel the full benefit of the treatment. Continue to take the tablets regularly even when you start to feel better. If you stop before your doctor advises, your condition may worsen again. If, however, you feel no better after taking it for six months, you should discuss this with your doctor, as a different medicine may be more suitable for you.
If you buy any medicines, check with a pharmacist that they are suitable to take with hydroxychloroquine.
Hydroxychloroquine may stop the oral typhoid vaccine from working. If you are having any vaccinations, make sure the person treating you knows that you are taking this medicine.
