What is Zidoval gel?

Zidoval is an antibiotic gel used to treat bacterial vaginosis infection.

It contains the antibiotic active ingredient, Metronidazole.

What is bacterial vaginosis?

Bacterial vaginosis (BV) is an infection which causes a greyish white and watery vaginal discharge.

50% of women do not experience symptoms of BV, which can make it difficult to tell if you have it. Moreover, BV does not cause itching or pain.

If you suspect you have BV, speak to your doctor.

While BV is not technically a sexually transmitted infection (STI), it can be caused by sexual intercourse with a new partner or having multiple sexual partners. BV can also be triggered by having an STI. It is believed that sex and STIs upset the careful balance of usual bacteria in the vagina, which can cause bacterial vaginosis infection.

However, women who are not sexually active can also experience BV.

While the exact cause of BV is unknown, you may be at a higher risk of BV if you:

  • use perfumed soaps to wash the genital area
  • use antiseptic bath additives
  • have a contraceptive IUD (intra-uterine device)
  • change your sexual partner
  • are sexually active

Bacterial vaginosis is not a serious condition, but you should still seek treatment. If left unchecked, BV can cause complications in pregnancy and increase your risk of pelvic inflammatory disease (PID).

How does Zidoval work for bacterial vaginosis?

Zidoval contains an antibiotic called Metronidazole.

Metronidazole kills anaerobic bacteria, such as the ones which cause bacterial vaginosis, by altering the DNA of the bacteria and preventing them from reproducing. This stops the infection from spreading and gives the immune system a better chance of fighting the infection.

How long does Zidoval gel take to work?

Zidoval gel takes up to to 5 days to work for bacterial vaginosis infection.

If your symptoms do not improve after completing the 5 days treatment course, speak to your doctor.

How do I use Zidoval gel?

Zidoval gel comes with disposable applicators, which are used to insert the gel in your vagina.

The gel is usually used once a day for 5 days.

You should apply the gel at bedtime.

It is important to use Zidoval gel at the same time each day. If you have difficulty remembering when to take medicines, set a reminder on your phone or smart speaker. You can also store your medicine in a place which will remind you when to take it.

Before you use Zidoval gel, it is important to wash your hands with soap and water.

You should use a new applicator for every dose of Zidoval gel. Do not reuse the applicators.

Used applicators can be thrown in your household waste.

  1. Open the tube by unscrewing the cap. Use the pointed end of the cap to pierce the end of the tube.
  2. Take one of the applicators and screw it onto the end of the tube.
  3. Squeeze the tube gently to fill the applicator with Zidoval. As the applicator fills up, the plunger will move. Once the plunger reaches 5g (the recommended dose), it will stop moving. At this point, the plunger is filled.
  4. Carefully remove the applicator from the end of the Zidoval tube and replace the cap of the tube.
  5. Holding the filled applicator by the barrel, gently insert it into your vagina as far as is comfortable. This may be easier to do on your back with your knees bent.
  6. Slowly depress the plunger to release the gel into your vagina. Keep pressing down the plunger until it stops to ensure all the gel has been applied.
  7. Remove the applicator from your vagina and discard the used applicator in a bin.

After applying Zidoval gel, wash your hands with soap and water.

You should repeat these steps for 5 consecutive days. If you do not feel better after completing the 5 days course, speak to your doctor.

What should I do if I forget to use Zidoval gel when I should?

If you forget to use Zidoval gel when you should, skip the missed dose and apply it at your next bedtime.

Do not use more Zidoval gel to make up for the missed dose.

What should I do if I accidentally apply more Zidoval gel than I should?

If you accidentally use more Zidoval gel than you should, seek advice from your doctor or a pharmacist.

Do not use more Zidoval gel than you should. Using more Zidoval gel will not clear your infection faster byt may increase your risk of side effects.
