Ampicillin for infections

Penbritin

Make sure you tell your doctor if you are allergic to penicillin. Ampicillin is a type of penicillin - do inte take it if you are allergic to penicillin.

Space your doses out evenly over the day and complete the full course of the antibiotic, even if you feel your infection has cleared up. You should take ampicillin when your stomach is empty of food (so an hour before you eat, or two hours afterwards).

Om du får en allergisk reaktion (som svullnad runt munnen, andningssvårigheter eller ett rött utslag) kontakta en läkare omedelbart.

Ampicillin is given to treat a bacterial infection. It is mainly prescribed for sinus och bröstinfektioner, urine infections, and öroninfektioner. It is a penicillin antibiotic which treats infection by killing the germs (bacteria) responsible for the infection.

Before taking ampicillin

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 ampicillin it is important that your doctor knows:

  • If you suspect you may have glandular fever (the symptoms are high temperature (fever), sore throat, swollen glands).

  • If you have an allergic condition, or if you have ever had an allergic reaction to a medicine. This is especially important if you have ever had a bad reaction to any penicillin antibiotic.

  • Om du har några problem med hur dina njurar fungerar.

  • If you are pregnant or breastfeeding. Ampicillin is not known to be harmful to babies; however, it is still important that you tell your doctor if you are expecting or breastfeeding a baby.

  • Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

How to take ampicillin

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

  • Take ampicillin exactly as your doctor tells you to. It is usually taken four times a day, every six hours. Your doctor or pharmacist will tell you how you should take the medication, and this information will be printed on the label of the pack to remind you. It is important that you space out the doses evenly during the day. Swallow the capsules with a drink of water.

  • You should take ampicillin when your stomach is empty, which means taking your doses one hour before you eat any food, or waiting until two hours afterwards. This is because your body absorbs less ampicillin after a meal, which means the medicine is less effective.

  • Om du har fått flytande medicin för ett barn, läs anvisningarna noggrant för att säkerställa att du mäter upp rätt mängd medicin.

  • 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 forgotten dose.

Få ut det mesta av din behandling

  • Even if you feel your infection has cleared up, keep taking the antibiotic until the course is finished (unless a doctor tells you to stop). This is to prevent the infection from coming back.

  • Antibiotics are prescribed in short courses of treatment. Your doctor will tell you how long your course of treatment will last - this is not usually for longer than 14 days. If you still feel unwell after finishing the course, go back to see your doctor.

  • Some people develop redness and itching in the mouth or vagina (thrush) after taking a course of antibiotics. If this happens to you, speak with your doctor or pharmacist for advice.

  • If you are taking the contraceptive 'pill' at the same time as this antibiotic, the effectiveness of the 'pill' can be reduced if you have a bout of being sick (vomiting) or diarrhoea which lasts for more than 24 hours. If this should happen, ask your doctor or pharmacist for advice about what additional contraceptive precautions to use over the next few days. There is no need to use additional precautions for any bouts of sickness or diarrhoea which last for less than 24 hours.

  • Ampicillin can 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 this antibiotic.
