Zidoval Vaginal Gel is not recommended for use in children (under the age of 12 years), as there have been no studies of its effects in children.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.

This medicine has been prescribed by your doctor for you only. Do not let someone else use it, as it may be harmful to them.

Taking other medicines

Some medicines and Zidoval Vaginal Gel may interfere with each other. These include:
medicine to prevent blood clotting (e.g. Warfarin)
lithium or disulfiram or cyclosporin or 5-fluorouracil
Carmustine (BCNU) or cyclophosphamide
These medicines may be affected by Zidoval Vaginal Gel or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while using this medicine.
Before using Zidoval Vaginal Gel, discuss with your doctor whether you may consume alcohol while using Zidoval. There have been reports of unpleasant reaction (flushing, headache, feeling of being sick, fast heart beat) associated with drinking alcohol whilst taking metronidazole tablets by mouth. However, when using Zidoval by vaginal application, only very small amounts of metronidazole are getting into the blood, making any reaction with alcohol unlikely, although it cannot be ruled out.

How to use Zidoval Vaginal Gel

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to use

Disposable applicators are provided to help you apply the gel into the vagina. When filled with gel, each applicator contains one single dose (5g) of Zidoval Vaginal Gel.
Insert one applicator full of Zidoval Vaginal Gel into the vagina at bed time. Repeat this procedure using a new applicator at bedtime for 5 consecutive days or as directed by your doctor

How to use it

Your tube of Zidoval Vaginal Gel is packed in a box which also contains five disposable (throw away) vaginal applicators.
To ensure maximum hygiene, always:
Wash your hands before opening the tube or touching the applicator
Use a new applicator for each dose
Immediately throw away the used applicator in the waste bin
Opening the tube
Before using Zidoval Vaginal Gel for the first time, you will need to puncture the metal seal on the tube. To do this, simply unscrew the cap from the tube and pierce the seal using the pointed tip of the cap.
Filling the applicator
Step 1: Remove an applicator from the wrapper. Unscrew the cap from the tube and screw the open end of the applicator onto the tube.
Step 2: Squeeze the tube slowly from the bottom to fill the applicator with gel; the plunger will move as the applicator fills and will stop moving when the applicator contains the correct amount of gel.
Step 3: Unscrew the applicator and replace the cap on the tube.
Inserting the applicator
Hold the filled applicator by its barrel and gently insert it into your vagina as far as it will comfortably go.
You may find it easiest to do this whilst lying on your back with your knees bent; alternately, choose any position you find comfortable.
Applying the gel
Slowly press the plunger to deposit the gel into your vagina; continue pressing until the plunger stops (this will ensure you have released the correct amount of gel). Remove the applicator from the vagina and throw it in the waste bin immediately.

When to use it

Insert one applicator full of Zidoval Vaginal Gel into the vagina at bed time.
Use your medicine at about the same time each day.
Using it at the same time each day will have the best effect. It will also help you remember when to use it.

How long to use it

Continue using your medicine for as long as your doctor tells you.
It is important to keep using your medicine as directed by your doctor.

If you forget to use it

If you miss a bed time dose of Zidoval Vaginal Gel, apply the missed dose as soon as you remember the next morning and then continue to use the next dose at bedtime until the full course, as prescribed by your doctor, has been used.
Do not double the dose at any time to make up for the missed dose. If it is almost the time to apply the next dose when you remember that you have missed a dose, skip the missed dose, apply the next dose at bedtime and continue treatment until the full course, as prescribed by your doctor, has been used
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you use too much(overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Zidoval Vaginal Gel.

You may need urgent medical attention.
It is important to keep to the dose as prescribed by your doctor. But if you accidentally apply more than one full applicator of Zidoval Vaginal Gel in one day, there is no need to worry. The use of more than one dose in a day is not expected to cause you any problems, although you may be more likely to experience side effects as described below.
