What Is Zidoval Gel?

If you are experiencing the telltale signs of bacterial vaginosis (BV) — such as unusual discharge or an unpleasant odour — Zidoval Gel may be an effective treatment option. Bacterial vaginosis is a common vaginal infection caused by an imbalance in the natural bacteria of the vagina, and it can cause significant discomfort and worry.

Zidoval Gel is a prescription-only vaginal gel containing metronidazole 0.75% — a potent nitroimidazole antibiotic. Metronidazole is effective against the anaerobic bacteria responsible for BV, and Zidoval’s unique vaginal delivery system ensures the medication works directly at the site of infection. Available through Access Doctor, Zidoval Gel offers a convenient, discreet way to treat BV without waiting for a GP appointment.

How Does Zidoval Work?

Zidoval Gel is specifically designed for vaginal application. Inserted directly into the vagina using the provided applicators, the gel delivers metronidazole precisely where it is needed. Metronidazole is a nitroimidazole antibiotic that works by entering bacterial cells and interfering with their DNA — effectively killing the anaerobic bacteria causing BV and allowing the vaginal flora to restore itself to a healthy, lactobacilli-dominant balance. This targeted action helps eliminate symptoms quickly.

See our detailed explainer: Your guide to using metronidazole — how it works and what to expect.

Benefits of Using Zidoval Gel

  • Highly effective: Metronidazole gel has a success rate of up to 91% — a first-line choice recommended by NICE and widely prescribed by UK clinicians
  • Fast relief: Many women notice improvement within 2–3 days of starting the course
  • Convenient application: Pre-measured applicators make applying Zidoval easy and mess-free
  • Targeted local treatment: Applied directly to the vagina — high local concentration where it is needed most
  • Discreet delivery: Access Doctor dispatches Zidoval in plain, unmarked packaging, ensuring complete privacy

How to Use Zidoval Gel

Zidoval Gel comes with 5 tubes of gel and 5 disposable applicators. Use one applicator each night for 5 consecutive nights — ideally just before bed.

  1. 1

    Wash hands

    Wash your hands thoroughly with soap and water before handling the gel and applicator.

  2. 2

    Fill the applicator

    Remove the cap from the Zidoval tube. Screw on a fresh disposable applicator and gently squeeze the tube to fill it until the plunger stops moving.

  3. 3

    Insert and administer

    Lie on your back with knees bent and slightly apart. Insert the applicator tip high into your vagina, then slowly push the plunger to release the gel.

  4. 4

    Dispose and repeat

    Gently remove and immediately discard the applicator. Repeat each night for 5 consecutive nights.

Do not double dose if you miss a dose — apply as soon as you remember unless it is almost time for the next dose. Complete the full 5-night course even if symptoms improve earlier.

When Will I Feel Better?

You should start to notice an improvement in BV symptoms — including vaginal odour and discharge — within a few days of starting your Zidoval course. However, it is essential to complete the entire 5-night course to ensure the infection has been fully cleared. Stopping early risks the infection returning.

If symptoms persist after completing the treatment, consult your prescriber. You may require an alternative such as Dalacin Cream (clindamycin) or tinidazole.

Important Considerations Before Using Zidoval Gel

Consideration Guidance
Alcohol Avoid all alcohol during treatment and for at least 48 hours after. Metronidazole + alcohol causes a disulfiram-like reaction.
Allergies Tell your prescriber if allergic to metronidazole, other nitroimidazole antibiotics, or any Zidoval ingredients including parabens.
Medical conditions Certain blood disorders require caution. Always disclose your full medical history during your consultation.
Pregnancy / breastfeeding Discuss with your prescriber before using Zidoval. Generally considered safe, but personalised advice is essential.
Menstruation Avoid using during your period. If your period starts during treatment, speak to your prescriber.
Tampons Do not use tampons during treatment — they absorb the gel and reduce effectiveness.
Sexual intercourse Avoid sexual intercourse during the 5-night treatment course.
Drug interactions Warfarin, lithium, 5-fluorouracil, and ciclosporin can interact with metronidazole. Inform your prescriber of all medications.

Vaginal Health Tips

  • Wash the vaginal area daily with mild, unperfumed soap and water
  • Avoid douching — it disrupts the protective bacterial balance
  • Wear breathable cotton underwear and avoid tight-fitting clothing
  • Use condoms consistently to reduce the risk of BV-associated bacterial disruption
  • Always wipe from front to back
