2 Medicine Indications

3 Dosage for Anaerobic infections 

Metronidazole is  given three times a day.  morning, early afternoon and at bedtime.make these times at least 6 hours apart, for example 8 am, 2 pm and 8 pm.
Give the medicine at about the same time each day so that this becomes part of your child’s daily routine, which will help you to remember.

How much should I give?

please check the table below for exact dose
Tablets should be swallowed with a glass of water, milk or juice. Your child should not chew the tablet.
Liquid medicine: Shake the bottle well and measure out the right amount using an oral syringe or medicine spoon. You can get these from your pharmacist. Do not use a kitchen teaspoon as it will not give the right amount.

4 Dosage for gingivitis

When should the medicine start working?

Your child should start to get better after taking the medicine for 2–3 days. It is important that they take the whole course of the medicine that has been prescribed. Do not stop early.

What if my child is sick (vomits)?

  • If your child is sick less than 30 minutes after having a dose of metronidazole, give them the same dose again.
  • If your child is sick more than 30 minutes after having a dose of metronidazole, you do not need to give them another dose. Wait until the next normal dose.

What if I forget to give it?

Do not give the missed dose. Just give the next dose as usual.

What if I give too much?

Metronidazole is normally a safe drug. It is unlikely to cause any problems if you give an extra dose by mistake. If you are worried that you may have given your child too much metronidazole, contact your doctor or local NHS services (111 in England and Scotland; 0845 4647 in Wales). Have the medicine or packaging with you if you telephone for advice.

9 Side Effects
We use medicines to make our children better, but sometimes they have other effects that we don’t want (side-effects).
Side-effects are rare with metronidazole and do not usually last for long. They will get better after a day or two as your child’s body gets used to the medicine, and should go away when the treatment course is finished.
Side-effects you must do something about
Serious side-effects are very unlikely with metronidazole.
  • f your child gets a yellowish tinge to the skin or whites of the eyes, contact your doctor straight away, as there may be a problem with their liver.
  • If your child is very tired, or has unusual bruising or bleeding, contact your doctor as there may be a problem with their blood.
  • Other side-effects you need to know about
    • Your child may have diarrhoea, stomach pains, feel sick or be sick (vomit) when they first start to take metronidazole. The box overleaf gives advice on what to do.
    • Contact your doctor if your child has diarrhoea that goes on for more than 4 days or if it is severe and watery, or contains blood.
    • Your child’s tongue may feel furry to them. Sucking or chewing a piece of fruit or a sweet may help. Your child may also get mouth ulcers. If this occurs contact your doctor.
    • Your child may have a metallic or bitter taste in their mouth. Eating citrus fruits or taking sips of water may help.
    • Your child may feel less hungry (lose their appetite). Encourage them to eat small meals often.
    There may, sometimes, be other side-effects that are not listed above. If you notice anything unusual and are concerned, contact your doctor.
  • Can other medicines be given at the same time as metronidazole?

    • You can give your child medicines that contain paracetamol or ibuprofen, unless your doctor has told you not to.
    • Metronidazole should not be taken with some medicines that you get on prescription. Tell your doctor and pharmacist about any other medicines your child is taking before giving metronidazole.
    • Check with your doctor or pharmacist before giving any other medicines to your child. This includes herbal or complementary medicines.

    Is there anything else I need to know about this medicine?

    If your child has ever had a reaction to any antibiotic, tell your doctor or pharmacist before giving metronidazole.
    • Teenagers should be aware that they must not drink alcohol while taking metronidazole, and for 48 hours after finishing the course, as it is likely to make them unwell. They are likely to feel sick (nausea) or be sick (vomit), have stomach pains, hot flushes, headache and a fast or uneven heartbeat.
