Rifampicin is an antibiotic which is prescribed to treat a variety of serious infections. It is frequently prescribed to treat la tuberculose (TB). When prescribed in this way, it is usually prescribed as just one of a number of medicines to treat the infection. Alternatively, rifampicin can be prescribed to protect you from getting a serious infection (including TB, meningitis, or Haemophilus influenzae) because you have been in close contact with someone who has the infection.

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 usually need to be taken for six months. As several medicines are given together to treat TB, there are some brands of rifampicin tablets which contain the medicine in combination with one or more other medicines used to treat TB. These combination brands help to reduce the total number of tablets that need to be taken each day, and are listed in the table above.

Before taking rifampicin

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 rifampicin it is important that your doctor knows:

  • Si vous êtes enceinte ou si vous allaitez.

  • If you have any problems with how your liver works, or any problems with the way your kidneys work.

  • If you have any yellowing of your skin or of the whites of your eyes (jaundice).

  • Si vous avez un trouble sanguin héréditaire rare appelé porphyrie.

  • Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et les médecines complémentaires.

  • Si vous avez déjà eu une réaction allergique à un médicament.

How to take rifampicin

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

  • There are several ways rifampicin could be prescribed for you, depending upon the reason why you are taking it. Your doctor will tell you how much to take for each dose. It is very important that you take it exactly as your doctor tells you to. Your dose will be printed on the label of the pack to remind you about what the doctor said to you, but if you are still unsure what to do, ask your pharmacist to explain it to you again. As a guide:

    • You may be asked to take one dose a day. This is the standard treatment for TB.

    • You may be asked to take one dose three times a week while you are being supervised. This is called directly observed therapy (DOT) for TB.

    • You may be asked to take one dose several times a day. This is the treatment for serious infections such as brucellosis and Legionnaires' disease.

    • You may be asked to take two doses a day, for two days. This is to protect against meningitis.

    • You may be asked to take one dose every day for four days. This is to protect against Haemophilus influenzae.

    • You may be asked to take one dose once a month while you are being supervised. This is the standard dose for leprosy.

  • Try to take your doses at the same time of day each day, as this will help you to remember to take them regularly. You should take rifampicin 'on an empty stomach'. This means that you should take your doses about an hour before a meal, or wait until two hours afterwards. This is because your body absorbs less rifampicin if taken at the same time as food, which means it is less effective.

  • If you have been given rifampicin liquid medicine to give to your child, please read the directions carefully to make sure that you give the correct amount.

  • If you forget to take a dose, take one as soon as you remember. Try to take the correct number of doses each day but do not take two doses at the same time to make up for a missed dose.

  • You must complete the full course of treatment (unless your doctor tells you otherwise), or your infection may come back. If you are taking rifampicin for TB, a course of treatment usually lasts for around six months.

Tirer le meilleur parti de votre traitement

  • It is important that you keep your regular appointments with your doctor. This is so your doctor can check on your progress. Your doctor may want you to have some blood tests from time to time during the treatment to make sure that your blood and liver are working properly.

  • There are several different brands and strengths of tablets and capsules. Each time you collect a new supply of medicine from your pharmacy, please check to make sure it looks to be the same as you have had before. If you have any questions about what you have been given, ask your pharmacist for further advice.

  • Rifampicin can cause your urine and sweat to have an orange or reddish colour. This is completely harmless - it is nothing for you to worry about.

  • If you wear soft contact lenses, please be aware that rifampicin can cause your lenses to become discoloured or stained. You may want to discuss this with your doctor or optician. An alternative type of contact lens may be more suitable for you, or alternatively, you may be advised to wear glasses instead.

  • Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. The contraceptive effect of 'the pill', 'mini pill', contraceptive patches and vaginal rings is reduced by rifampicin and so these on their own are not suitable types of birth control while you are on rifampicin.

  • If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because rifampicin can interfere with a number of other medicines (including some painkillers) and stop them from working properly. Also, some medicines (such as antacids for indigestion) can stop rifampicin from working properly and must not be taken at the same time.

  • If for any reason you miss any doses, you should let your doctor know about this. If your treatment is interrupted for any length of time, your doctor may want to adjust your dose.

  • Rifampicin can stop the oral typhoid vaccine from working as it should. If you are due to have any vaccinations, please make sure that the person treating you knows that you are taking this medicine.

  • If you are due to have an operation or any dental treatment, please tell the person carrying out the treatment that you are taking an antibiotic called rifampicin.

Questions fréquemment posées

Why is it important to take rifampicin on an empty stomach?

Taking rifampicin on an empty stomach means you should take your doses about an hour before a meal, or two hours afterwards. This is because food can reduce the amount of rifampicin your body absorbs, making the medication less effective.

What should I do if I accidentally miss a dose of rifampicin?

If you forget to take a dose, take it as soon as you remember. Try to take the correct number of doses each day. However, it's important not to take two doses at the same time to make up for a missed dose. If you miss multiple doses or your treatment is interrupted for any length of time, you should let your doctor know, as they may need to adjust your dose.

Can rifampicin affect vaccinations?

Yes, rifampicin can stop the oral typhoid vaccine from working as it should. If you are due to have any vaccinations, it is important to inform the person treating you that you are taking this medicine.

How quickly do rifampicin side effects usually improve?

Many of the unwanted side-effects often improve as your body adjusts to the new medicine. However, if any side effects continue or become troublesome, you should speak with your doctor or pharmacist for advice.

What are the common signs of potential liver problems I should watch out for while taking rifampicin?

While your doctor will monitor you for liver problems, you should contact them as soon as possible if you notice any unexplained sickness (nausea or vomiting), yellowing of your skin or eyes (jaundice), unexpected weight loss, or if you feel extremely tired.
