Generic name: Metronidazole.
Brand names: Flagyl and Metrogel.
Available as: an ovule, oral suspension, tablet or injection

How to use it?
Tablets: Swallow the tablet whole with half a glass of water. Don’t break it and don’t chew on it.
Oral suspension: shake the bottle before use and measure the correct amount with the supplied measuring spoon/cup.
Ovule: needs to be inserted deep into the vagina.

Duration of treatment?
Usually 1-10 days.
It is important that you do not interrupt the treatment and finish it completely.

When to use it?
Metronidazole is used for ”serious” infections caused by micro-organisms sensitive to Metronidazole.

What is the correct dosage?
Always use the dosage and frequency prescribed by your own doctor.

What are the side-effects?
Common: (1-10%): Increased sensitivity for additional infections.
Uncommon (0.1-1%): general body weakness.
Rare (0.01-0.1%): severe allergic reaction and convulsions.

Safety:
You should not drive while using Metronidazole and you should not combine it with alcohol.
Furthermore, the usage of Metronidazole can have interactions with some other drugs and it can be dangerous for people with liver and neurological problems. Therefore always ask your prescribing physician if metronidazole is safe for you.

Pregnancy and Lactation:
The usage of metronidazole while pregnant or while breastfeeding is usually considered to be safe, but you should always ask your doctor if Metronidazole is safe for you and your baby.
