Ethambutol is used to treat Tuberkulose (TB). TB is a bacterial infection which is mostly found in the lungs but which can affect any part of your body. TB is treatable with a course of medicines which need to be taken for six months. You will need to take several medicines to treat TB - ethambutol is one of the medicines prescribed during the first two months of the treatment.

Ethambutol will be prescribed for you by a doctor who specialises in the treatment of TB. It is important that you take it regularly.

Before taking ethambutol

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking ethambutol, it is important that your doctor knows:

  • If you are pregnant or breastfeeding. (Although ethambutol is not known to be harmful to babies, it is still important that you tell your doctor if you are expecting or breastfeeding a baby.)

  • If you have any problems with your eyesight.

  • Wenn Sie Probleme mit der Funktionsweise Ihrer Nieren haben.

  • Wenn Sie andere Medikamente einnehmen. Dazu gehören auch Medikamente, die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

  • Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

How to take ethambutol

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

  • Ethambutol will be prescribed for you in one of two ways - you will entweder be asked to take one dose every day, oder, one dose three times a week. Your doctor will tell you which way is right for you. If you are asked to take one dose three times a week, you will be supervised while you take the doses. This is called directly observed therapy (DOT).

  • If you are taking ethambutol every day, try to take your doses at the same time of day each day, as this will help you to remember to take ethambutol regularly. Your doctor will tell you how many tablets to take for each dose, as this will be individually tailored to suit you and depends upon your weight. It is important that you take ethambutol exactly as you are told. You can take the tablets either with or without food. If you forget to take a dose at your usual time, take it as soon as you remember, but do not take two doses on the same day to make up for a missed dose.

Das Beste aus Ihrer Behandlung herausholen

  • It is important that you keep your regular clinic appointments with your doctor. This is so your doctor can check on your progress. Your doctor may want you to have blood tests from time to time during the treatment to make sure you have just the right amount of the medicine in your bloodstream.

  • Continue to take the tablets regularly - do not stop taking ethambutol unless your doctor tells you to stop. This is because it is important for you to complete the course of medicine so that the infection does not come back. Your treatment with ethambutol will last for two months (unless you develop troublesome side-effects).

  • Ethambutol can stop the oral typhoid vaccine from working properly. If you are due to have any vaccinations, make sure that the person treating you knows you are taking this medicine. Also, if you are due to have an operation or any dental treatment, you should tell the person carrying out the treatment that you are taking medicines for TB.

  • If you buy any medicines 'over the counter', check with a pharmacist that they are suitable for you to take alongside your prescribed medicines. Antacid remedies for indigestion which contain aluminium hydroxide are not suitable while you are taking ethambutol.
