What is Zidoval?

Zidoval is a branded gel that contains the medicine metronidazole. This is an antibacterial agent that fights the cause of infection directly.

Zidoval gel can help to get rid of bacterial vaginosis symptoms, including:

  • a thin, grey, watery vaginal discharge
  • a strong smell

Side effects and contraindications

Like with any medication, there are side effects that you may get from using Zidoval gel.

Common side effects of Zidoval gel include:

  • stomach cramps
  • headache and dizziness
  • an unpleasant taste in your mouth
  • dry skin
  • unusual feeling on your tongue
  • itching of the skin (pruritus)

Uncommon side effects of Zidoval gel include:

  • depression
  • tiredness
  • feeling sick
  • unusual feeling in your toes and fingers
  • gurgling or bloated stomach
  • metallic taste in your mouth

Although rare, there are some serious side effects that you can get from using Zidoval gel. Seek urgent medical help if you have a serious allergic reaction, or you get numbness, tingling, or burning in your feet or hands.

Let your doctor or pharmacist know if you are currently taking, have recently taken, or may take any other medicines alongside Zidoval gel. This is because the gel may affect how other medicines work, including:

  • lithium (used to treat mental illness)
  • warfarin (used to prevent blood clotting)
  • cyclosporin (used to treat rheumatoid arthritis and autoimmune diseases)
  • 5-fluorouracil (used in cancer treatment and for skin problems)

Zidoval gel contains propyl parahydroxybenzoate and methyl parahydroxybenzoate (E218) which can cause allergic reactions. There is also 30mg propylene glycol (E1520) in each gram that can cause skin irritation. Any medications purchased with or without a prescription may interact with treatment, so let your doctor know of any before using Zidoval gel.
