About isoniazid

Isoniazid is used to treat tuberculosis (TB). TB is a bacterial infection which mostly affects the lungs, but which can affect any part of your body. It is treatable with a course of medicines which usually lasts for six months in total. You will need to take several medicines to treat TB - isoniazid is just one of the medicines prescribed.

Isoniazid is usually prescribed as a tablet which contains a combination of two, three or four medicines to treat TB. The brand names of these are Rifinah®, Rifater®, Rimstar® and Voractiv®. You may be prescribed one or more of these brands at different times in your treatment. Taking combination medicines like these helps to reduce the total number of tablets you need to take each day.

Although isoniazid is a very effective medicine, it can sometimes cause damage to peripheral nerves (such as numbness and tingling sensations in the hands and feet). If you are considered to be at risk of this, your doctor will prescribe you a vitamin supplement of pyridoxine to prevent it.

Before taking isoniazid

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 isoniazid it is important that your doctor knows:

• If you are pregnant, trying for a baby or breastfeeding. Although isoniazid is not known to be harmful in pregnancy, it is important that you tell your doctor, as you may need to be given a vitamin supplement.

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

• If you have epilepsy or diabetes.

• If you have ever had a mental health problem called psychosis.

• If you drink a lot of alcohol, or if you do not eat a sufficient amount.

• If you are HIV-positive.

• If you know you have slow acetylator status. This means that your body may process isoniazid more slowly, leading to an increased risk of side-effects.

• If you have a rare inherited blood condition called porphyria.

• यदि आप कोई अन्य दवाएं ले रहे हैं। इसमें वे सभी दवाएं शामिल हैं जो आप बिना पर्ची के खरीद सकते हैं, साथ ही हर्बल और पूरक दवाएं भी शामिल हैं।.

• यदि आपको कभी किसी दवा से एलर्जी की प्रतिक्रिया हुई है।.

How to take isoniazid

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

• It is important that you take the medicines to treat TB exactly as your doctor tells you to. You will be asked to take isoniazid every day. Your doctor will explain to you how many tablets to take each day, and this information will be printed on the label of the pack of tablets to remind you. If when you collect your supply of tablets you are unclear about how to take them, ask your pharmacist to explain.

• The ideal time to take your tablets each day is half an hour before breakfast. If you forget, then take the tablets two hours after breakfast or wait until half an hour before your next meal. This is because isoniazid is absorbed better when your stomach is empty.

• It is important that you keep your regular appointments with your doctor. This is so your doctor can check on your progress. Your doctor will want you to have blood tests from time to time during treatment to make sure that your liver stays healthy.

• Continue to take the tablets regularly unless your doctor tells you to stop. This is because it is important for you to complete the treatment course so that the infection does not come back. If for any reason you stop taking the tablets (such as if you think you may be developing side-effects - see also below) then you must let your doctor know about it straightaway so that you can be given alternative treatment.

• If you buy any medicines, check with a pharmacist first that they are suitable for you to take with isoniazid. Some antacid preparations can reduce the amount of the medicine that your body absorbs.

• Some foods may interact with isoniazid. Try to avoid eating foods containing histamine or tyramine. Examples include tuna fish, fermented or pickled products, strong cheeses, cured meats and red wine.

• You should try to avoid drinking alcohol whilst taking isoniazid, as the combination could harm your liver.

• Isoniazid 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.

• If you are having an operation or any dental treatment, tell the person carrying out the treatment which medicines you are taking.

Can isoniazid cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains the most common ones associated with isoniazid. You will find a full list in the manufacturer's information leaflet supplied with your medicine. Unwanted effects often improve as your body adjusts to a new medicine, but speak with your doctor or pharmacist if any become troublesome.

Important: isoniazid on rare occasions causes liver problems. The symptoms include persistent sickness (nausea and vomiting), feeling very weak and yellowing of the skin and whites of the eyes (jaundice). If this happens to you, speak with your doctor or go to your local accident and emergency department straightaway.

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