1. what co-amoxiclav is and what it is used for

Co-amoxiclav is an antibiotic and works by killing bacteria that cause infections. It contains two different medicines called amoxicillin and clavulanic acid. Amoxicillin belongs to a group of medicines called “penicillins” that can sometimes be stopped from working (made inactive). The other active component (clavulanic acid) stops this from happening.

Co-amoxiclav is used in adults and children to treat the following infections:

• severe ear, nose and throat infections
• respiratory tract infections
• urinary tract infections
• skin and soft tissue infections including dental infections
• bone and joint infections
• intra-abdominal infections
• genital organ infections in women.

Co-amoxiclav is used in adults and children to prevent infections associated with major surgical procedures.

Blood and urine tests

If you are having blood tests (such as red blood cell status tests or liver function tests) or urine tests (for glucose), let the doctor or nurse know that you are taking Co-amoxiclav. This is because Co-amoxiclav can affect the results of these types of tests.

Other medicines and Co-amoxiclav

Tell your doctor, pharmacist or nurse if you are using, have recently used or might use any other medicines. This includes medicines that can be bought without a prescription and herbal medicines.

If you are taking allopurinol (used for gout) with Co-amoxiclav, it may be more likely that you’ll have an allergic skin reaction.

If you are taking probenecid (used for gout), your doctor may decide to adjust your dose of Co-amoxiclav.

If medicines to help stop blood clots (such as warfarin) are taken with Co-amoxiclav then extra blood tests may be needed.

Co-amoxiclav can affect how methotrexate (a medicine used to treat cancer or rheumatic diseases) works.

Co-amoxiclav may affect how mycophenolate mofetil (a medicine used to prevent the rejection of transplanted organs) works.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor, pharmacist or nurse for advice before taking this medicine.

Driving and using machines

Co-amoxiclav can have side effects and the symptoms may make you unfit to drive. Do not drive or operate machinery unless you are feeling well.

500 mg/100 mg powder for injection or infusion

• Co-amoxiclav, 500 mg/100 mg contains approximately 31.4 mg (1.4 mmol) of sodium. This is equivalent to 1.57 % of the recommended maximum daily dietary intake of sodium for an adult.
• Co-amoxiclav, 500 mg/100 mg contains approximately 19.6 mg (0.5 mmol) of potassium i.e. essentially‘po­tassium-free’.

1000 mg/200 mg powder for injection or infusion

• Co-amoxiclav, 1000 mg/200 mg contains approximately 62.9 mg (2.7 mmol) of sodium. This is equivalent to 3.145 % of the recommended maximum daily dietary intake of sodium for an adult.
• Co-amoxiclav, 1000 mg/200 mg contains approximately 39.3 mg (1.0 mmol) of potassium. To be taken into consideration by patients with reduced kidney function or patients on a controlled potassium diet.

2. what you need to know before you have co-amoxiclav

Do not take Co-amoxiclav:

• if you are allergic to amoxicillin, clavulanic acid, penicillin or any of the other ingredients of this medicine (listed in section 6)
• if you have ever had a severe allergic reaction to any other antibiotic. This can include a skin rash or swelling of the face or throat
• if you have ever had liver problems or jaundice (yellowing of the skin) when taking an antibiotic.

Do not take Co-amoxiclav if any of the above apply to you. If you are not sure, talk to your doctor, pharmacist or nurse before having Co-amoxiclav.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Co-amoxiclav if you:

• have glandular fever
• are being treated for liver or kidney problems
• are not passing water regularly.

If you are not sure if any of the above apply to you, talk to your doctor, pharmacist or nurse before taking Co-amoxiclav.

In some cases, your doctor may investigate the type of bacteria that is causing your infection. Depending on the results, you may be given a different strength of Co-amoxiclav or a different medicine.

Conditions you need to look out for

Co-amoxiclav can make some existing conditions worse, or cause serious side effects. These include allergic reactions, convulsions (fits) and inflammation of the large intestine. You must look out for certain symptoms while you are taking Co-amoxiclav, to reduce the risk of any problems. See ‘Conditions you need to look out for’ in Section 4.

You will never give yourself this medicine. A qualified person, like a doctor or a nurse, will give you this medicine.

The following information is intended for medical or healthcare professionals only:

Co-amoxiclav 500 mg/100 mg Powder for Solution for Injection/Infusion

Co-amoxiclav 1000 mg/200 mg Powder for Solution for Injection/Infusion

Amoxicillin/Cla­vulanic Acid

This is an extract from the Summary of Product Characteristics (SmPC) to assist in the administration of Co-amoxiclav. When determining appropriateness of use in a particular patient, the prescriber should be familiar with the SmPC.

ADMINISTRATION

Co-amoxiclav 500 mg/100 mg, Co-amoxiclav 1000 mg/200 mg Powder for Solution for Injection/Infusion may be administered either by slow intravenous injection over a period of 3 to 4 min directly into a vein or via a drip tube or by infusion over 30 to 40 min. Amoxicillin/cla­vulanic acid is not suitable for intramuscular administration.

INCOMPATIBILITIES WITH DILUENTS AND OTHER MEDICINAL PRODUCTS

Co-amoxiclav 500 mg/100 mg or 1000 mg/200 mg Powder for Solution for Injection/Infusion must not be mixed with amino acid solutions, lipid emulsions, blood and glucose solutions.

Co-amoxiclav 500 mg/100 mg or 1000 mg/200 mg Powder for Solution for Injection/Infusion is less stable in infusions containing dextran or bicarbonate. Reconstituted solution should therefore, not be added to such infusions but may be injected into the drip tubing over a period of three to four minutes.

Because of the inactivation of aminoglycosides by amoxicillin, in-vitro mixing should be avoided.

INSTRUCTIONS FOR USE AND HANDLING

The reconstitution is to be made under aseptic conditions. The solution is to be inspected visually for particulate matter prior to administration. The solution should only be used if the solution is clear and free from particles. Any unused solution should be discarded.From a microbiological point of view, unless the method of reconstitution precludes the risk of microbial contamination, the injection and infusion solutions should be used immediately. If not used immediately, in-use storage times and conditions are the responsibility of the user.

For single use only.

Co-amoxiclav 500 mg/100 mg

Preparation of intravenous injections:

Vials of 500 mg/100 mg are diluted with 10 ml or up to 20 ml of water for injections.

Vial of	Water for injection	Volume after reconstitution*	Concentration after reconstitution*
500 mg/100 mg	10 ml	10.0 ml	50.0/10.0 mg/ml
500 mg/100 mg	20 ml	20.2 ml	24.8/5.0 mg/ml

• Make sure you drink plenty of fluids while having Co-amoxiclav.

If you have any further questions about how this medicine is given, ask your doctor, pharmacist or nurse.

The reconstitution of the ready to use solution for infusion has to take place in two steps in order to allow the reconstitution of the necessary volume for solution for infusion:

The vial of 500/100 mg is first reconstituted with one of the compatible intravenous fluids in its vial. This solution has then to be transferred into a suitable infusion bag which should contain the same compatible fluid as used for reconstitution. Controlled and validated aseptic conditions have to be observed.

Vials of 500/100 mg are diluted with 25 ml or up to 50 ml of water for injection or of the following fluids: Physiological saline, Sodium lactate 167 mmol/l, Ringer’s solution, Hartmann's so­lution.

If the product is dissolved in water for injection as specified, this solution may be mixed with the following solvents: Water for injection, Physiological saline, Sodium lactate 167 mmol/l, Ringer’s solution, Hartmann's so­lution.
