What is Zidoval 0.75% Gel?

Zidoval 0.75% gel contains Metronidazole, which is a antibacterial that works by killing many kinds of bacteria that cause infections. Zidoval gel is an effective treatment for certain infections of the vagina (called bacterial vaginosis or BV for short) in adults. BV is a mild bacterial infection of the vagina, characterised by grey-white discharge with a fishy smell.

Zidoval gel is applied inside the vagina where it destroys the bacteria at the site of the infection. It is important that bacterial vaginosis is treated and cleared completely otherwise the infection can come back. You must take the full course of this medicine as prescribed by your doctor to prevent this from happening.

Zidoval gel can help to clear up BV infections usually within 7 days.

How do you use it?

Bacterial vaginosis

Bacterial vaginosis (BV) is a common cause of unusual vaginal discharge. BV isn’t a sexually transmitted infection (STI), but it can increase your risk of getting an STI such as chlamydia.

Check if you have bacterial vaginosis

The most common symptom of bacterial vaginosis is unusual vaginal discharge that has a strong fishy smell, particularly after sex.

You may notice a change to the colour and consistency of your discharge, such as becoming greyish-white and thin and watery.

But 50% of women with bacterial vaginosis don’t have any symptoms.

Bacterial vaginosis doesn’t usually cause any soreness or itching.

If you’re unsure it’s BV, check for other causes of unusual vaginal discharge.

See a GP or go to a sexual health clinic if you think you have BV The condition isn’t usually serious, but you’ll need to be treated with antibiotics if you do have BV.

It’s also important to seek treatment if you’re pregnant as there’s a small chance that BV can cause complications with pregnancy.

Treatment for bacterial vaginosis

Bacterial vaginosis is usually treated with antibiotic tablets or gels or creams.

Recurring bacterial vaginosis

It’s common for BV to come back, usually within 3 months.
You’ll need to take treatment for longer (up to 6 months) if you keep getting BV (you get it more than twice in 6 months).

To help relieve symptoms and prevent bacterial vaginosis returning:


use water and plain soap to wash your genital area have showers instead of baths


do not use perfumed soaps, bubble bath, shampoo or shower gel in the bath do not use vaginal deodorants, washes or douches do not put antiseptic liquids in the bath do not use strong detergents to wash your underwear do not smoke

What causes bacterial vaginosis

Bacterial vaginosis is caused by a change in the natural balance of bacteria in your vagina.

What causes this to happen isn’t fully known, but you’re more likely to get it if:

you’re sexually active (but women who haven’t had sex can also get BV) you have had a change of partner you have an IUD (contraception device) you use perfumed products in or around your vagina BV isn’t an STI, even though it can be triggered by sex.

You’re more likely to get an STI if you have BV. This may be because BV makes your vagina less acidic and reduces your natural defences against infection.
