    Clavulin (Amoxicillin,Clavulanate Potassium) Dosage and Side Effects

    CLAVULIN is an antibiotic which is used to treat various bacterial infections.

    Proper Use of this medication


    The usual adult dose is 1 CLAVULIN 500 mg tablet every 12 hours. For more severe infections and infections of the lower respiratory tract, your doctor may prescribe 1 CLAVULIN 875 mg tablet every 12 hours or 1 CLAVULIN 500 mg tablet every 8 hours.


    For children aged 12 weeks (3 months) and older as directed by a doctor:

    Infants and children less than 12 weeks (3 months):

    The recommended dose of CLAVULIN is 30 mg per kg per day in divided doses every 12 hours as directed by a doctor.

    The children’s dosage should not exceed that recommended for adults. Children weighing more than 38 kg should be dosed according to the adult recommendations.

    You must follow the doctor's advice and use the medicine as instructed. Your doctor will decide how much medicine you or your child need each day, and how many days you should take it for.

    It is better to take CLAVULIN at the same time as a meal, but CLAVULIN still works if it is given without food.

    If there is anything you do not understand please ask your doctor or pharmacist.


    In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

    Missed dose:

    If you or your child miss a dose of CLAVULIN, take it as soon as you remember. However, if it is almost time for the next dose, do not take the missed dose. Instead, continue with your next scheduled dose. Do not try to make up for the missed dose by taking double the dose next time.

    Side Effects

    The following are very rare side-effects that may happen in people taking CLAVULIN:

    • the tongue may change colour to yellow, brown or black, and it may have a hairy appearance.
    • teeth discolouration while using CLAVULIN. This is less likely to happen if teeth are cleaned thoroughly, and any discolouration can usually be removed by brushing. If the discolouration does not disappear, ask your doctor or dentist for advice.

    These are common side-effects that may happen in people taking CLAVULIN:

    • a yeast infection of the nails, skin, mouth, vagina, stomach, urinary tract (mucocutaneous candidiasis)
    • nausea (feeling sick) and vomiting (being sick) in adults and children
    • diarrhoea (loose, or watery bowel movements) in children

    These are uncommon side-effects that may happen in people taking CLAVULIN:

    • indigestion
    • headache

    If you experience symptoms such as severe diarrhea (bloody or watery) with or without fever, abdominal pain, or tenderness, you may have Clostridium difficile colitis (bowel inflammation). If this occurs, stop taking Clavulin and contact your healthcare professional immediately.

    Warnings and Precautions

    BEFORE you use CLAVULIN talk to your doctor or pharmacist if you or your child:

    • are allergic to amoxicillin or beta-lactam antibiotics (such as penicillins and cephalosporins) or any of the other ingredients of CLAVULIN. If you or your child have had an allergic reaction (such as a rash) when taking an antibiotic, you should talk to your doctor before taking CLAVULIN.
    • develop a skin rash while taking CLAVULIN. Stop taking CLAVULIN and immediately tell your doctor.
    • have glandular fever (mononucleosis) and are prescribed CLAVULIN. Please talk to your doctor before taking CLAVULIN.
    • have liver or kidney problems.
    • suffer from a condition called phenylketonuria (PKU). This is because CLAVULIN contains aspartame.

    • are breastfeeding or planning to breastfeed. Penicillins including amoxicillin are excreted in human breast milk. Discuss with your doctor.
