Bacterial Vaginosis Treatment

As bacterial vaginosis (BV) is caused by an overgrowth of bad bacteria, the treatment is a course of antibiotics. Usually, the antibiotic metronidazole is given, but clindamycin can also be used.

BV antibiotics can be taken as tablets or as a cream or gel that’s inserted into the vagina using an applicator. No matter what form you use, antibiotics help clear up symptoms in a few days, but they may not stop your symptoms from coming back.

If your BV symptoms return, speak to your doctor for advice on other treatments you could try.

To get the full effect of your treatment, you should complete the full course and avoid missing any doses, even if you feel better. If you forget your dose, take the next one as soon as you remember, unless it’s almost time for your next dose, then skip it and take the next one as normal.

If you are pregnant, it’s important to discuss treatment with a doctor, as not all BV treatments will be suitable for you.

BV tablets

Metronidazole is the most common antibiotic tablet used to treat BV. It’s usually taken at a strength of 400mg, twice a day, for 5 to 7 days. In some cases, a single large dose of 2g of metronidazole may be given.

Metronidazole works by damaging the DNA of the bacteria that cause bacterial vaginosis, causing the bacteria to die and BV symptoms to improve.

Metronidazole tablets are an effective BV treatment. One study shows that BV symptoms resolved in 70% of women taking metronidazole tablets. Another study found that BV was treated effectively in 85.1% of women taking metronidazole.

Do not drink while taking metronidazole and for 48 hours after stopping, as alcohol can interact with metronidazole and cause sickness and vomiting.

If metronidazole is not effective or you’re unable to take it, you may be offered another antibiotic tablet called clindamycin instead. Asda Online Doctor does not offer clindamycin tablets for BV, so this should be discussed with your GP or a sexual health clinic.

BV creams

Bacterial vaginosis creams and gels can be inserted into the vagina to treat symptoms at the source. Some of these creams contain antibiotics to kill the bacteria causing BV while others contain lactic acid to support the good bacteria in the vagina.

You can request Zidoval metronidazole vaginal gel and Dalacin clindamycin vaginal cream from Asda Online Doctor. Both contain antibiotics.

Zidoval

Zidoval gel contains 7.5mg of metronidazole in every gram of gel. One application of gel is 5g. You’ll use it every night for 5 nights in a row.

To use Zidoval, fill the applicator and insert it into the vagina while laying on your back. Release the gel into the vagina by pushing down, remove the applicator, and throw it away.

Dalacin

Dalacin cream contains 20mg of clindamycin in every gram of cream, and one dose of cream is 5g. This antibiotic cream is also inserted into the vagina using an applicator and should be used every night for 7 days.

Although many people take BV treatment without a problem, some people can experience side effects. These are usually mild and can be managed at home, but more serious side effects should be discussed with a doctor.

Side effects of vaginal gels and creams

Common side effects include:

• inflammation or infection of the vulva and vagina
• vaginal discharge

Side effects of metronidazole tablets

For metronidazole tablets, the most common side effects are gastrointestinal symptoms, such as feeling or being sick. One study found more than 50% of people taking metronidazole tablets had these side effects.

This can typically be managed by eating smaller amounts of plain food and staying hydrated. They should get better after finishing the course of antibiotics.

Other, much rarer side effects include:

• low blood cell count
• psychotic disorders, including confusion or hallucinations
• swelling of the brain
• vision disorders

If you experience any of these rare side effects, speak to a doctor straight away, and call 999 in an emergency, such as if you’re struggling to breathe or are confused.

A full list of side effects for each treatment can be found in the patient information leaflet inside the packaging.

It’s important to tell your doctor about any medical conditions you have or medications that you’re taking before taking BV treatment. This will help your doctor make sure it’s safe for you to take the medication.

Bacterial vaginosis can lead to uncomfortable symptoms, increased vaginal discharge, and an unpleasant odour. Although mild symptoms do not necessarily need treatment, they can cause discomfort, and you may feel self-conscious.

Getting treatment helps to restore the natural balance of bacteria in the vagina, giving the good bacteria a chance to flourish. It should improve any symptoms that are bothering you.

Having BV can also increase your risk of catching STIs, as the normal bacteria that protect your vagina are depleted. This means it’s often a good idea to seek treatment if you are sexually active. In some cases, your sexual partner may also need treatment.

If you are terminating a pregnancy or about to undergo a gynaecological procedure, you’ll likely need treatment for BV even if you’re not experiencing symptoms. This is because there’s a risk that the bacteria causing BV could be spread to the womb.

Women who are pregnant are usually also treated for BV, as it can increase the risk of early labour and miscarriage.

You can get BV treatment from your GP, a sexual health clinic, or you can request it online from a reputable service like Asda Online Doctor.

Is BV treatment available over the counter?

No, antibiotics for BV require a prescription, so they are not available to buy over the counter. Other treatments for BV, like lactic acid, can be bought over the counter, but there’s limited evidence as to how effective these treatments are.

Bacterial vaginosis is an infection of the vagina that’s caused by an overgrowth of bad bacteria.

It’s normal for there to be bacteria inside your vagina, but BV happens when there’s too many of the “bad” bacteria and not enough of the “good” bacteria.

This imbalance can cause the pH of the vagina to become less acidic than normal which in turn makes more of the bad bacteria grow.

Although BV does not always cause symptoms, it can cause the normal vaginal discharge to change and become:

• white or grey and more watery
• fishy smelling
• heavier and more fishy after sex or after a period

It’s possible to experience some itching or soreness, but this is not common.

BV is more common if you’re sexually active, especially after a recent change in partner or if you have sex with different partners quite often. You can still get BV even if you’re not sexually active, though.

Other factors that can trigger BV include:

• smoking
• having a copper coil (intrauterine device)
• using bubble bath
• having long or heavy periods
• hormonal changes, like pregnancy or menopause
• taking antibiotics
• too much washing around the vagina
• using scented products around the vagina
• douching or washing inside the vagina

There’s not always a clear trigger for BV, and you may not be able to prevent it all the time. But you can try to avoid doing things that are known to trigger BV as much as you can.

This means:

• showering rather than taking baths
• avoiding scented products near your vagina
• stopping smoking
• changing period products often

If your BV does not clear up after treatment or you get symptoms again soon after, it’s best to get it checked out by a doctor in case there’s another cause for your symptoms. You may need to take antibiotic treatment for longer to stop BV from coming back, usually if you get it more than 4 times in a year.
