Zidoval gel is a gel-based antibacterial medication which is used to treat the infection of the vagina called bacterial vaginosis (BV).

The Zidoval gel contains the active ingredient metronidazole, an antibiotic which kills the vaginal bacteria at the site of the infection.

The medicine is applied for 5 days in a row to accomplish effective treatment.

The gel is an effective treatment option for symptomatic bacterial vaginosis. This is a common infection where there is an overgrowth of bacteria inside the vagina. One usually experiences a vaginal discharge with a fishy odour.

Instructions of how to use the gel will be mentioned in the leaflet that comes along with the gel. Make sure that you use the gel as per your doctor’s instructions. The gel must be used consecutively for five daays. Each day, one disposable applicatorful (approximately 5 grams) should be applied.

The gel is best applied at bedtime. Because there are chances of the medicine leaking from the vagina, and this gets minimized during night time. Also, it is useful to apply the gel at the same time every day to maintain a cycle and prevent forgetting the dose.

If you forget to use the dose, use it as soon as you remember. If it is already time for the next dose, then continue as usual. Do not take a double dosage. In case you have skipped a day, take the medicine dosage for the correct number of total days as recommended.

If you take an overdose, you will need emergency medical help. Visit the Accident and Emergency Centre at your nearest local hospital.
