Co-amoxiclav for infections

About co-amoxiclav

Co-amoxiclav is a type of penicillin given to treat bacterial infections. It is prescribed for sinus infections, urine infections, skin infections, joint infections and some dental infections. It is also given before some surgical operations, to prevent an infection from developing.

Co-amoxiclav contains two ingredients, amoxicillin and clavulanic acid. The first ingredient, amoxicillin, is a penicillin antibiotic which treats infection by killing the bacteria responsible for the infection. Some bacteria are able to produce a chemical which makes amoxicillin less effective. The second ingredient, clavulanic acid, stops this from happening. Clavulanic acid stops the chemical produced by the bacteria from working, and this allows the amoxicillin to kill the bacteria.

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-amoxiclav it is important that your doctor knows:

• If you suspect you may have glandular fever.

• 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.

• If you are pregnant or breastfeeding. Co-amoxiclav 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.

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

• Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

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

• Take co-amoxiclav exactly as your doctor tells you to. It is usually taken three times daily, every eight hours. It is important that you space out the doses evenly during the day. Your doctor or pharmacist will tell you how many tablets (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.

• Try to drink plenty of water while you are taking co-amoxiclav, to help keep your kidneys working well. You can take your doses before or after food.

• 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.

• If you (or your child) have been prescribed the oral liquid medicine, you may find that it causes some staining of the teeth. This will disappear soon after the course of antibiotics is finished.

• 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 - 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.

• Co-amoxiclav 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.

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-amoxiclav.
