Metronidazole for bacterial infection

About metronidazole

Metronidazole is an المضاد الحيوي used to treat a wide variety of bacterial infections caused by anaerobic bacteria and types of micro-organisms called protozoa.

These types of organisms often cause infections in areas of the body such as the gums, pelvic cavity and tummy (stomach or intestines) because they do not need oxygen to grow and multiply.

Metronidazole is commonly prescribed to treat bacterial vaginosis, and, is also prescribed before gynaecological surgery and surgery on the intestines, to prevent infection from developing.

Metronidazole is also used, alongside other medicines, to get rid of Helicobacter pylori, a bacterial infection often associated with stomach ulcers.

It can safely be taken by people who are allergic to penicillin.

Metronidazole is available as a skin preparation also. This leaflet does not give information about metronidazole when it is used for skin conditions, but there is more information available in a separate leaflet called Metronidazole skin gel and cream.

Common side effects of metronidazole are:

• الشعور بالغثيان.

• Being sick.

• Changes in how things taste.

• Furred tongue

• Sore mouth.

• Lack of appetite.

You will find a full list in the manufacturer's information leaflet supplied with your medicine.
