How do I take/use this medicine?

Take Metronidazole exactly as directed by your doctor. Do not take more or less than instructed by your doctor.

Take Metronidazole at regular intervals as instructed. Do not skip any doses. Continue to take it even when you feel better. You must complete the entire course of antibiotic. If you don't, the infection will not clear completely.

If you have been given the tablet or capsule, take it with food or immediately after a meal.

If you have been given the oral liquid (also known as a syrup), take it on an empty stomach, at least 1 hour before meals. Shake it well before use to ensure that the liquid is evenly mixed.

What should I take note of while using/taking this medicine?

Alert your doctor if you have heart, liver, kidney or blood diseases, epilepsy, oral or vaginal yeast infections.

Alert your doctor if you are pregnant or breastfeeding.

If you are being treated with Metronidazole for STD, you should follow your doctor's advice on ways to prevent passing the disease to others. You should also avoid sexual contact until the doctor certifies that you are cleared of the infection.

When should I not use this medicine?

Alert your doctor if you ever had an allergic reaction (breathlessness, rashes, swollen eyes) to a similar antibiotic called tinidazole.

Are there any restrictions on the type of food I can take?

Avoid alcohol while being treated with Metronidazole and for 24 or 72 hours (if you are taking the extended-release tablets or capsules) after the last dose; otherwise you may experience severe flushing, headache, nausea, vomiting and stomach cramps.

Why do I need this medicine?

Metronidazole is an antibiotic. It is used to treat dental, lung, skin, vagina, bone and joint infections, infection of the digestive tract and certain sexually transmitted diseases (STD).

It is also used together with other medicines for gastric ulcers caused by a type of bacteria known as Helicobacter pylori.

What side effects could I experience?

Metronidazole may cause dizziness. If you feel dizzy, do not drive or take part in any activity in which you need to be alert.

Metronidazole may cause diarrhoea, nausea, loss of appetite, metallic taste in the mouth, constipation and dark or tea-coloured urine. These side effects are usually temporary. If you have diarrhoea, drink lots of water to replace the fluids lost. However, if you have severe diarrhoea or diarrhoea with severe stomach cramps or bloody stools, alert your doctor.

If you develop rashes, breathlessness, swollen mouth or eyes, stop the medicine and inform your doctor quickly. These could be signs of an allergic reaction.

Metronidazole may cause other side effects. Consult your doctor if you have unusual problems while taking this medicine.

How should I store this medicine?

Store in a cool, dry place away from the reach of children. Protect from light.

The oral liquid can be stored at room temperature of up to 25°C. If the suspension has been diluted (ask your doctor or pharmacist if you are not sure), do not use it after 14 days.

Medicines must not be used past the expiry date.

Can I take/use this with other medicines?

Alert your doctor if you are taking any of these medicines:

- warfarin (a blood-thinning medicine)
- lithium (a mood medicine)
- phenytoin, phenobarbitone (epilepsy medicines)
- ciclosporin (a medicine for organ transplant)
- fluorouracil (a cancer medicine)
- disulfiram (a medicine used to treat alcoholism)
