About Metronidazole Tablets

What are metronidazole tablets?

Metronidazole tablets are an antibiotic which is used to treat a variety of conditions including:

  • bacterial vaginosis (BV)
  • skin infections, rosacea and mouth infections
  • pelvic inflammatory disease
  • infected insect bites, skin ulcers, bed sores, and wounds
Metronidazole is also available in liquid, gel, cream, and a suppository (which is inserted into your bottom). It is also given by injection in the hospital. 

You need a prescription to take metronidazole. A doctor will decide how you should take metronidazole, the dose and for how long. You can buy metronidazole tablets to treat BV from at Superdrug Online Doctor.

How do metronidazole tablets work?

Metronidazole tablets stop the growth of the bacteria (or parasite) that is causing the infection which is making you ill. 

How effective are metronidazole tablets for BV?

Studies show that metronidazole is over 90% effective at treating BV. In most cases, you should feel better within a few days of taking metronidazole.

How do I take metronidazole tablets? 

You take metronidazole tablets whole with water, during or after meals. Always follow the instructions from your doctor on how to take metronidazole as these instructions are specific to your condition.

It is essential that you do not drink alcohol while taking metronidazole or for 48 hours after you have finished your course. Drinking alcohol whilst taking metronidazole can cause unpleasant side effects such as being sick, headaches, hot flushes, and stomach pains. 

What are the dosages of metronidazole?

To treat bacterial vaginosis (BV), your doctor will prescribe you either a 1 day or 7 day course.

  • 1 day course: take 5 x 400mg metronidazole tablets at once
  • 7 day course: take 1 x 400mg tablet twice a day

To treat other common conditions, the dose will vary depending on your illness and your own health condition.

  • hives or an itchy rash
  • a stiff neck
  • headache
