Zidoval (Metronidazole) Gel

Zidoval is an antibiotic vaginal gel used for treating symptoms of bacterial vaginosis (BV) by delivering the active ingredient (metronidazole) directly into the vagina, where it acts on the bacteria causing the condition.

Zidoval is an antibiotic gel to be applied intravaginally (into the vagina) using one of the applicators provided. You should use one applicator‐full of the gel (about 5g) once daily at bedtime for five nights.

Directions for use:

1. Wash your hands before use.
2. Screw the applicator onto the tube and fill it until the plunger stops.
3. Lie on your back with knees bent (or whichever position is comfortable), insert applicator gently as far as comfortable, then depress the plunger to release gel.
4. Dispose of the applicator after use. Use a fresh one each night.

Zidoval gel is only suitable for adult women who have either suffered from BV in the past and recognise the symptoms, who have spoken to a healthcare professional for diagnosis of their BV, or who have taken a test which would indicate the presence of BV*. If this is the first time experiencing symptoms of BV without diagnosis or a self test, you may be refused this service.

This medication is not suitable for everyone, and it is important when completing our consultation forms to declare an accurate medical history in order to ensure patient safety when prescribing. You may be refused treatment if you:

• Are allergic to metronidazole (or any similar medications)
• Are menstruating
• Are pregnant or breastfeeding
• Have a history of liver problems
• Have a history of blood disorders (such as low white blood cell count)
• Have a nervous system disorder (such as epilesy or peripheral neuropathy)

*This test could be an at-home self-testing kit measuring the vaginal pH level. Available through our self-testing page.

Common side effects to this line of treatment may include vaginal irritation (itchiness, burning), abnormal vaginal discharge, headaches, or nausea. These effect are usually mild and temporary.

Serious side effects, though rare, should be reported to a doctor immediately. These can include an allergic reaction, difficulty breathing, or a severe skin reaction.

No. Though absorption is lower with a vaginal gel than with oral medications, it is still advised to avoid all alcohol intake during treatment and for at least 48hrs after your final dose.

It is not recommended to start or continue treatment during a menstrual period because effectiveness may be reduced. Sexual intercourse during treatment is also discouraged until the infection is cleared and treatment finished.
