Co-fluampicil for infection

smorse84 fionaxoxo earthandfire 103 Users are discussing this topic

Make sure you tell your doctor if you are allergic to penicillin. Co-fluampicil is a type of penicillin - do not take it if you are allergic to penicillin.

Co-fluampicil should be taken four times a day, 30-60 minutes before meals.

Space your doses out evenly over the day and complete the full course of antibiotic.

If you have an allergic reaction (such as any swelling around your mouth, any difficulties breathing or a red rash) contact a doctor straightaway.

Type of medicinePenicillin antibiotic
Used forBacterial infections (adults and children)
Available asCapsules, oral liquid medicine, and injection

Co-fluampicil contains two penicillin antibiotics in equal amounts - flucloxacillin and ampicillin. It is used to treat bacterial infections. It works by killing the bacteria causing the infection.

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-fluampicil it is important that your doctor or pharmacist knows:

  • If you are pregnant or breast-feeding. (Although co-fluampicil is not known to be harmful to babies, it is still important that you tell your doctor if you are expecting or breast-feeding a baby.)
  • If you think you have glandular fever.
  • If you have problems with the way your liver works.
  • If you have kidney problems.
  • If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
  • If you have an allergic condition, or if you have ever had an allergic reaction to a medicine. This is particularly important if you have ever had a bad reaction to any penicillin antibiotic.
  • Before you start this antibiotic, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about co-fluampicil and a full list of side-effects which you may experience from taking it.
  • Take co-fluampicil exactly as your doctor tells you to. It is taken four times daily - space the doses out evenly during the day. Your doctor or pharmacist will tell you how many capsules (or how much liquid medicine) to take for each dose, and this information will be printed on the label of the pack to remind you. If you have been given liquid medicine for a child, read the directions carefully to make sure you measure out the correct amount of medicine.
  • You should take co-fluampicil about an hour before a meal. This is because your body absorbs less of the antibiotic if there is food in your stomach, which means the medicine is less effective.
  • Swallow the capsules whole - do not chew or open them. Some people find it helps to swallow the capsules with a drink of water.
  • 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.
  • Even if you feel your infection has cleared up, keep taking the antibiotic until the course is finished, unless you are told to stop. This is to prevent the infection from coming back. Your doctor will tell you how long your course of treatment will last. If you still feel unwell after finishing the course, go back to see your doctor.
  • Some people develop thrush (redness and itching in the mouth or vagina) after taking a course of antibiotics. If you think you have thrush speak with your doctor or pharmacist for advice.
  • If you are having an operation or any other medical treatment, tell the person carrying out the treatment that you are taking an antibiotic.
  • Co-fluampicil 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 antibiotic.
  • If you are taking co-fluampicil over an extended period of time, your doctor will want to routinely check on your progress. Try to keep any regular appointments you have booked with your doctor, as you will need to have some blood tests to check that your liver and kidneys are working well.
  • 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 vomiting or diarrhoea which lasts for more than 24 hours. If this should happen to you (for whatever reason), ask your doctor or pharmacist for advice about what additional contraceptive precautions to use. There is no need to use additional precautions for any bouts of sickness or diarrhoea which last for less than 24 hours.

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-fluampicil. 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.

Common co-fluampicil side-effectsWhat can I do if I experience this?
Feeling or being sickStick to simple foods
DiarrhoeaDrink plenty of water to replace any lost fluids. If the diarrhoea continues, becomes severe, or contains blood, let your doctor know straightaway
Skin rashLet your doctor know as soon as possible, as your treatment may need to be changed

Important: if you develop an itchy rash, swollen face or mouth, or have difficulty breathing, these may be signs that you are allergic to a penicillin antibiotic. Do not take any more co-fluampicil and 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 the medicine, speak with your doctor or pharmacist.

  • Keep all medicines out of the reach and sight of children.
  • Store co-fluampicil capsules in a cool, dry place, away from direct heat and light.
  • If you have been given liquid medicine, store it in a refrigerator. It will have been made up by the pharmacy, so check the expiry date on the bottle and do not use it after this date.

Never take more than the prescribed dose. If you suspect that you or someone else might have taken an overdose of this medicine, go to the accident and emergency department of your local hospital. Take the container with you, even if it is empty.

This medicine is for you. Never give it to other people even if their condition appears to be the same as yours.

If you buy any medicines, check with a pharmacist that they are safe to take with your other medicines.

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

Do not keep out-of-date or unwanted medicines. Take them to your local pharmacy which will dispose of them for you.

If you have any questions about this medicine ask your pharmacist.
