BV Antibiotic Treatment Tablets

Bacterial vaginosis is thought to be caused by a change in the natural balance of bacteria that live in the vagina. Because Metronidazole has antibiotic properties, it helps to kill excess bacteria and return the balance to normal, reducing the symptoms.

Metronidazole (also spelt Metronidazol) can be used to treat a number of different bacterial infections, though we only prescribe it to treat Bacterial Vaginosis (BV) in women. It is an effective BV treatment that can typically clear symptoms in two to three days and should be taken for the full course.

Metronidazole is suitable to buy online if you have previously suffered from bacterial vaginosis that has been diagnosed and successfully treated by your GP.

You may qualify for BV treatment online if you have:

• Developed vaginal symptoms such as a fishy odour and a thin discharge
• Had bacterial vaginosis diagnosed by your doctor
• Had a positive home test for bacterial vaginosis
• Had positive results using Metronidazole prescribed for bacterial vaginosis

If you have not suffered from BV before, your symptoms are not typical of BV, or you have had a negative test result, you should see your GP or visit a local sexual health clinic for further investigation.

Metronidazole tablets can also be used to treat recurrent bacterial vaginosis. It is not uncommon for BV to return within three months of first treatment. As long as the first course of Metronidazole was successful and your symptoms are the same as they were before you completed that course, you’re safe to use Metronidazole again.

If you have BV more than twice in 6 months or 4 times in 12 months, you should consult a GP or sexual health clinic.

A yeast infection is not the same as BV. Although both infections can cause similar symptoms, their causes are distinct. A yeast infection (such as thrush) is caused by a fungus overgrowth, whereas BV is caused by bacterial overgrowth. Thrush doesn’t tend to have a fishy odour like BV, but it does produce a distinct discharge that is similar to cottage cheese in appearance.

Take 1 oral tablet twice daily for 7 days. Metronidazole should be taken with or after food.
Always ensure that you complete the course, even if you think your symptoms have improved. This will help to prevent the infection from coming back.

You should avoid alcohol while taking Metronidazole and for at least 48 hours after your course has finished. Alcohol can cause a serious interaction with Metronidazole that results in nausea and vomiting.

Metronidazole can interact with alcohol - you should avoid alcohol while you are taking Metronidazole and for 24 hours after you have completed the course. You can read more about Metronidazole and alcohol here.

BV can affect women of any age, but it is more common in sexually active women during their reproductive years. It is not, however, a sexually transmitted infection (STI). Finding the right treatment, such as Metronidazole tablets, will help clear up symptoms, but there are also things you can do to prevent BV from recurring.

You can lower your risk of contracting BV by:

• Always use condoms when sleeping with multiple sexual partners
• Avoiding using fragranced products in and around your vagina as this can cause irritation. Water is enough to keep your vagina’s bacteria well-balanced.
• Always wipe front to back after using the toilet
• Wearing breathable underwear
• Including probiotics in your diet

Preventative measures can stop BV from recurring, but if your symptoms are already present then a course of medication will be most effective.

• An unpleasant taste in the mouth
• A furred tongue
• Feeling sick (nausea)
• Being sick (vomiting)
• An upset stomach
• Diarrhoea
• Appetite loss
• Fever
• Feeling depressed
• Pain in your eyes (optic neuritis)

Rare side effects:

• Anaphylactic reactions
• Abnormal laboratory test results
• Blood and bone marrow problems (these may be fatal)
• Brain and central nervous system problems (including neurological problems): seek medical advice if you have symptoms such as fever, paralysis, photosensitivity, balance or coordination problems, a stiff neck, tremors, or epileptic seizures
• Convulsions
• Double vision
• Eye or eyesight problems
• Feeling dizzy
• Feeling drowsy

• Headaches
• Itching
• Jaundice
• Joint pain

If you experience any serious side effects, you should contact your doctor for further advice.

You should not take Metronidazole tablets if any of the following apply to you:

• You have (or have ever had) a liver problem
• You are having kidney dialysis
• You have a disease of the nervous system
• You are pregnant or breastfeeding

You should not take Metronidazole tablets if you take any of the following medicines:

• Anticoagulants (blood thinning agents), such as warfarin: the dosage of warfarin may need to be reduced if you are taking Metronidazole
• Lithium: if taken at the same time as metronidazole, it can affect the kidneys
• Medicines used to treat epilepsy (e.g. phenytoin, primidone, or phenobarbitone)
• 5-fluorouracil (for cancer)
• Disulfiram (for alcohol abuse)
• Cimetidine (for indigestion and heartburn)

You should not drink alcohol. The combination of Metronidazole and alcohol can cause unwanted side effects such as nausea, vomiting, flushing, stomach pain, palpitations and headaches.

No - there is no evidence that there is any interaction with oral or other types of hormonal contraception.

Metronidazole is used for vaginal infections for which pregnant women may sometimes require treatment, just like any others. The risk of miscarriage while using Metronidazole is thought to be unlikely. There’s no scientific evidence suggesting that Metronidazole is harmful to an unborn baby, but because it has not been fully studied, it’s not possible to say for sure that it’s absolutely safe to use while pregnant. You should consult your doctor if you develop a vaginal infection during pregnancy.
