bacteria. It is not suitable for all types of vaginal infections. By applying Zidoval
directly into the vagina, metronidazole can kill the bacteria at the site of the infection.

How much to use
Each dose consists of one applicator filled with 5 g of Zidoval gel.
How to use it
Your box of Zidoval contains a tube of vaginal gel and five single use 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
Dispose of the used applicator in the rubbish bin.
Opening the tube
Before using Zidoval Vaginal Gel for the first time, puncture the metal seal on the
tube. To do this, unscrew the cap from the tube and pierce the seal using the pointed
tip of the cap.
Filling the applicator
Remove an applicator from its wrapper. Unscrew the cap from the tube and screw the
open end of the applicator onto the tube.
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.
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.
Otherwise 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 put it in the rubbish bin.
When to use it
Use Zidoval at bedtime.
Vaginal medicines can leak out of the vagina during treatment. Using Zidoval at bedtime
will help reduce leakage. Using Zidoval at the same time each day will also help you
remember when to use it.
Wear a panty liner or sanitary napkin during treatment to help keep the medicine from
getting on your clothing. Do not use tampons as they may soak up the medicine and
stop you getting the full dose.
How long to use it
Apply Zidoval for 5 days in a row or for as long as your doctor tells you.
To help prevent reinfection, always complete the full course of treatment even if
your symptoms start to clear up within a few days.
If you forget to use it
If you forget to have a dose of Zidoval gel, use it as soon as you remember and continue
with your treatment as before.
If, by the time you remember, it is time to have your next dose, do not double-up
on your treatment. Have your original missed dose and continue your treatment as usual.
Never have more than one dose of the gel a day to make up for missed doses.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to use your medicine, ask your pharmacist for some
