Metronidazole is an antibiotic that can be used in the treatment of bacterial vaginosis. Symptoms, if any, can begin to clear within a few days.

For recurring BV that does not resolve with taking measures to prevent changes in the balance of the vagina, you may need a longer course of antibiotics.


  • How can I manage side effects?

    Side effects like diarrhoea can be reduced by using over the counter treatments such as Loperamide. Nausea can be prevented by taking Metronidazole with or just after food. There are options available for vomiting such as cyclizine, promethazine, and prochlorperazine, which can be purchased here at Pharmacy Online.

  • Can I drink alcohol while taking this medication?

    It is important that you do not drink alcohol while taking Metronidazole, during the course and up to seven days after finishing the course, as this can cause severe vomiting.

  • What should I do if I miss a dose?

    If you have forgotten to take a tablet, take one as soon as you remember if it has been less than 24 hours since you took your last tablet. You should then resume taking Metronidazole as normal.

    If more than 24 hours have passed since you took your last tablet, take your next tablet at the next scheduled time and taken as directed.

    It is important that you remember to take Metronidazole regularly as directed and to ensure you complete the course as failing to do so could prolong the infection.

  • Does Metronidazole cause thrush?

    Taking Metronidazole may cause thrush, as the antibiotic destroys the bacteria present in the body which protects you from developing thrush, leaving you at risk of developing it.
