1. What Amoxicillin/Clavulanic Acid Sandoz is and what it is used for

Amoxicillin/clavulanic acid is an antibiotic that kills bacteria causing infections. It contains two different medicines called amoxicillin and clavulanic acid. Amoxicillin belongs to a group of medicines known as "penicillins", which can sometimes become ineffective (inactivated). The other component (clavulanic acid) prevents this from happening.

Antibiotics are used to treat bacterial infections and are not effective against viral infections such as flu or the common cold.

It is important that you follow your doctor's instructions regarding dosage, administration, and duration of treatment.

Do not store or reuse this medicine. If you have any antibiotic left over after completing your treatment, return it to the pharmacy for proper disposal. Do not dispose of medicines via wastewater or household waste.

Amoxicillin/clavulanic acid is used in adults and children to treat the following infections:

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

Amoxicillin/clavulanic acid is used in adults to prevent infections associated with major surgical procedures.

2. What you need to know before you start using Amoxicillin/Clavulanic Acid Sandoz

Do not use Amoxicillin/Clavulanic Acid Sandoz:

• if you are allergic to the active substances or to any of the other ingredients of this medicine (listed in section 6)
• if you have ever had a severe allergic reaction (hypersensitivity) to any other antibiotic. This could include skin rash or swelling of the face or neck,
• if you have ever had liver problems or jaundice (yellowing of the skin) while taking an antibiotic.

?Do not receive Amoxicillin/Clavulanic Acid Sandoz if any of the above apply to you. If you are unsure, consult your doctor, pharmacist, or nurse.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before starting to use amoxicillin/clavulanic acid if:

• you have infectious mononucleosis,
• you are receiving treatment for liver or kidney problems,
• you do not urinate regularly.

If you are unsure whether any of the above conditions apply to you, inform your doctor, pharmacist, or nurse before receiving Amoxicillin/Clavulanic Acid.

In some cases, your doctor may investigate the type of bacteria causing your infection. Depending on the results, you may be prescribed a different formulation of amoxicillin/clavulanic acid or another medicine.

Symptoms to watch for

Amoxicillin/clavulanic acid may worsen certain existing conditions or cause serious adverse effects. These include allergic reactions, seizures, and inflammation of the large intestine. You should be aware of certain symptoms while being treated with amoxicillin/clavulanic acid to reduce the risk of complications. See “Symptoms to watch for” in section 4.

Blood and urine tests

If you are undergoing blood tests (such as studies of red blood cell status or liver function tests) or urine tests (to monitor glucose levels), inform your doctor or nurse that you are receiving amoxicillin/clavulanic acid. This is because amoxicillin/clavulanic acid may alter the results of these types of tests.

Use of Amoxicillin/Clavulanic Acid Sandoz with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription and herbal medicines.

If you are taking allopurinol (used for gout) with amoxicillin/clavulanic acid, you may be more likely to experience a skin allergic reaction.

Probenecid (used to treat gout): concomitant use of probenecid may reduce the excretion of amoxicillin and is not recommended.

If anticoagulants (such as warfarin) are taken with amoxicillin/clavulanic acid, more blood tests will be needed.

Methotrexate (a medicine used to treat cancer and severe psoriasis): penicillins may reduce the excretion of methotrexate and potentially increase its adverse effects.

Amoxicillin/clavulanic acid may affect how mycophenolate mofetil (a medicine used to prevent organ rejection in transplant patients) works.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor, pharmacist, or nurse before using this medicine.

Amoxicillin/Clavulanic Acid Sandoz contains sodium and potassium

This medicine contains 29.6 mg of sodium per vial, equivalent to 1.48% of the maximum daily intake of 2 g of sodium recommended by the WHO for an adult.

This medicine contains less than 39 mg (1 mmol) of potassium per vial and is therefore considered essentially “potassium-free”.

3. How to use Amoxicillin/Clavulanic Acid Sandoz

Never administer this medicine to yourself. A qualified person, such as a doctor or nurse, will give it to you.

The usual doses are:

Adults and children weighing 40 kg or more

Children weighing less than 40 kg

• All doses are calculated based on the child's body weight in kilograms.

Patients with kidney and liver problems

• if you have kidney problems, your dose may be adjusted. Your doctor may choose a different formulation or another medicine,
• if you have liver problems, you will have blood tests more frequently to monitor how your liver is functioning.

How Amoxicillin/Clavulanic Acid Sandoz will be administered to you

• amoxicillin/clavulanic acid will be given to you as an injection into a vein or by intravenous infusion,
• make sure you drink plenty of fluids while receiving amoxicillin/clavulanic acid,
• amoxicillin/clavulanic acid will not be administered for longer than two weeks without your doctor reviewing your treatment.

If you are given more Amoxicillin/Clavulanic Acid Sandoz than you should

It is very unlikely that you will be given too much amoxicillin/clavulanic acid, but if you think an overdose has occurred, tell your doctor, pharmacist, or nurse immediately. Symptoms may include stomach upset (nausea, vomiting, or diarrhea) or seizures.

If you have any further questions about how this medicine is administered, please consult your doctor, pharmacist, or nurse.
