Flucloxacillin for infection

About flucloxacillin

Flucloxacillin is a type of penicillin antibiotic used to treat bacterial infections such as ear infections, skin infections, bone infections, and heart and chest infections. It works by killing the bacteria causing the infection.

Flucloxacillin is also used before some surgical operations to prevent an infection from developing.

Flucloxacillin is available in combination with another antibiotic in a medicine called co-fluampicil. For information on this medicine read our leaflet Co-fluampicil for infection.

The most common side effects of flucloxacillin are:

• Feeling sick (nausea).

• הקאה.

• שלשול.

• Skin rash.

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.

Some medicines are not suitable for people with certain conditions. Before starting flucloxacillin it is important that your doctor or pharmacist knows:

• If you are pregnant or breastfeeding. (Although flucloxacillin is not known to be harmful to babies, it is still important that you tell your doctor if you are expecting or breastfeeding a baby.)

• If you have problems with the way your liver works.

• If you have kidney problems.

• אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• 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 flucloxacillin and a full list of side effects which you may experience from taking it.

• Take your dose of flucloxacillin exactly as your doctor tells you to. It is taken four times a 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 flucloxacillin 'on an empty stomach', which means you should take it about an hour before a meal, for example midday before lunch or in the morning before breakfast, or wait until two hours afterwards.

  • This is because your body absorbs less flucloxacillin after a meal, which means the medicine is less effective. Space the doses out evenly during the day.

• 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 using oral combined hormonal contraception (the 'pill'), additional contraceptive precautions such as condoms are recommended for a time if you have sickness (vomiting) or diarrhoea which lasts for more than 24 hours. If you need further advice about this, speak with your doctor or pharmacist.

• If you need pain relief whilst taking flucloxacillin it is best to speak to your doctor or a pharmacist first. The painkiller paracetamol is not always recommended during treatment with flucloxacillin, especially if you also have problems with the way your kidneys work.

• If you are having an operation or any other medical treatment, tell the person carrying out the treatment that you are taking an antibiotic.

• Flucloxacillin 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 flucloxacillin 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.

• שמור את כל התרופות מחוץ להישג ידם וראייתם של ילדים.

• Store flucloxacillin 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 and lasts for seven days, so check the expiry date on the bottle and do not use it after this date.

Is flucloxacillin good for ear infections?

Flucloxacillin is not usually the first choice for most ear infections. It mainly targets bacteria that cause skin and soft tissue infections, rather than the more common bacteria linked to middle ear infections.

Is flucloxacillin stronger than penicillin?

Flucloxacillin and penicillin are not stronger or weaker versions of each other, but different antibiotics used for different types of infections.

Will flucloxacillin affect my contraception?

Flucloxacillin does not affect most forms of contraception, including the combined pill and the progestogen-only pill. However, if the antibiotic causes vomiting or diarrhoea for more than 24 hours, your pill may not be absorbed properly. In that case, follow your pill’s guidance for missed pills and consider using extra protection until you’re well again.

Can I drive on flucloxacillin?

Yes, most people can drive while taking flucloxacillin, as it does not usually cause drowsiness. However, if you feel unwell, dizzy or light-headed from either the medicine or the infection itself, it is safer to avoid driving until you feel better.

Can I drink alcohol on flucloxacillin?

Yes, you can drink alcohol while taking flucloxacillin, as alcohol does not usually interfere with how the medicine works. However, it is best to drink in moderation, as alcohol can make you feel more tired or unwell when you are recovering from an infection

Is there any food or drink I need to avoid when taking flucloxacillin?

No, there are no specific foods or drinks you need to avoid while taking flucloxacillin. However, it is best to take the medicine on an empty stomach, either one hour before or two hours after eating, as food can reduce how well it is absorbed. Drinking plenty of fluids can also help your recovery.
