Patient leaflet - Anabact 0.75% w/w gel

1. WHAT ANABACT 0.75% w/w GEL IS AND WHAT IT IS USED FOR

Anabact 0.75% w/w Gel contains metronidazole. It is effective against the bacteria which cause the bad smell in infected tumours and ulcers. Metronidazole belongs to a group of medicines called antiprotozoal and antibacterial agents and has been shown to help to control infection and inflammation in certain skin problems, such as rosacea.

2. WHAT YOU NEED TO KNOW BEFORE YOU USE ANABACT 0.75% w/w GEL

Do not use Anabact 0.75% w/w Gel if you

  • are allergic (hypersensitive) to metronidazole or any of the other ingredients of Anabact 0.75% w/w Gel (see section 6). An allergic reaction may include a rash or itching.

Warnings and precautions

Talk to your doctor or pharmacist before using Anabact Gel.

  • Do not get the gel in your eyes. If you do, rinse thoroughly with large amounts of warm water or eye wash.
  • If you suffer from any blood disorders do not use Anabact Gel unless your doctor says you can.
  • This product should not be used in children.
  • Do not go out into strong sunlight (including sun-bathing) and avoid exposure to ultra-violet light (e.g. solariums, sun-lamps) while you are using this product.

Other medicines and Anabact Gel

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

  • Using Anabact Gel could interfere with drugs used to reduce blood clotting (anticoagulants) such as warfarin and dicoumarin. Contact your doctor for advice if you are taking medicines to reduce blood clotting, or if you suffer from any other blood disorders.

Anabact Gel with alcohol

Metronidazole taken by mouth can react with alcohol, but this effect has never been reported with metronidazole applied to the skin. Such an effect is extremely unlikely as the amount of metronidazole entering the blood through the skin is very small. However, you are advised not to drink alcohol while using Anabact Gel.

Pregnancy and breast-feeding

Do not use Anabact 0.75% w/w Gel if you are pregnant, think that you may be pregnant or if you are breast-feeding. Please ask your doctor or pharmacist for advice before taking any medicine.
