Co-trimoxazole for infection

About co-trimoxazole

Co-trimoxazole is a combination of two antibacterial medicines - a sulfonamide medicine called sulfamethoxazole, and trimethoprim. Although it has been prescribed widely for a range of infections in the past, it has very occasionally been associated with some serious side-effects. As a result, other antibiotics are now preferred to treat simple infections and co-trimoxazole is usually reserved for the treatment of more serious infections. In particular, it is prescribed for infections which can occur in people who have a problem with their immune systems. It works by killing the germs (bacteria) responsible for causing the infection.

Before taking co-trimoxazole

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 co-trimoxazole it is important that your doctor knows:

• Wenn Sie schwanger sind, ein Kind erwarten oder stillen.

• Wenn Sie Probleme mit der Funktionsweise Ihrer Leber oder Ihrer Nieren haben.

• Wenn Sie Asthma haben.

• If you have a blood disorder. It is particularly important that you tell your doctor if you have a rare inherited blood disorder called porphyria.

• If you have an enzyme deficiency called G6PD deficiency.

• If you have been told you have low amounts of the vitamin folic acid.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

• If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you have ever had a bad reaction to a sulfonamide antibiotic.

How to take co-trimoxazole

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

• Take co-trimoxazole exactly as your doctor tells you to. Your dose will depend upon whether you are being treated because you have an infection, or to prevent an infection. As a guide, it is usual to take two doses of co-trimoxazole daily (12 hours apart) to treat an infection, but make sure you read the directions on the label, as your dose may be different to this. If co-trimoxazole has been prescribed for your child, it is likely that you will be supplied a liquid medicine - the dose will depend upon the age of the child. Read the directions on the label carefully and make sure you measure out the correct dose.

• Remember to take co-trimoxazole regularly so that you keep a steady level of the medicine in your body. Try to avoid missing any doses.

• Co-trimoxazole is best taken with food or a drink.

• If you forget to take a dose, take it as soon as you remember. If it is almost time to take your next dose when you remember, skip the missed dose and take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.
  

Das Beste aus Ihrer Behandlung herausholen

• Try to drink several glasses of water each day while you are on co-trimoxazole. It is important that you do not become lacking in fluid in the body (dehydrated).

• Most people improve within a few days of starting treatment. If your symptoms do not improve despite taking co-trimoxazole, go back to see your doctor, as you may need an alternative antibiotic. This is because some bacteria are resistant to some types of antibiotics.

• Even if you feel your infection has cleared up, keep taking the antibiotic until the course is finished (unless your doctor tells you otherwise). This is to prevent the infection from coming back and being more difficult to treat. A typical course of treatment will last for 5-7 days, although the treatment of some of the more serious infections can take longer than this.

• Some people develop thrush (a yeast infection which causes redness and itchiness in the mouth or vagina) after taking a course of antibiotics. If you think you have thrush speak to your doctor or pharmacist for advice.

• Wenn Sie sich einer Operation oder einer zahnärztlichen Behandlung unterziehen müssen, teilen Sie der behandelnden Person mit, welche Arzneimittel Sie einnehmen.

• If you buy any medicines, check with a pharmacist that they are suitable to take with co-trimoxazole.

• This medicine may stop the oral typhoid vaccine from working. If you are due to have any vaccinations, make sure the person treating you knows that you are taking it.

• If you still feel unwell after completing your course of the antibiotic, make another appointment to see your doctor.

Can co-trimoxazole cause problems?

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

Wenn Sie andere Symptome haben, von denen Sie glauben, dass sie auf das Arzneimittel zurückzuführen sind, sprechen Sie mit Ihrem Arzt oder Apotheker, um weiteren Rat zu erhalten.
