Metronidazole is an antibiotic that’s commonly used to treat a sexually transmitted infection called trichomoniasis, also known as trich. The infection is caused by a parasite and is spread through unprotected sex and sharing sex toys.
Both men and women can get trichomoniasis. If you have the infection, you may have an abnormal discharge from your penis or vagina, itching or burning in your genital area, and may experience pain when you pee.
Only around 30% of people with trichomoniasis experience symptoms. This means you could have the infection – and pass it on to others – without realising.
Metronidazole is also used to treat bacterial vaginosis and a number of other bacterial infections. If you’re prescribed the antibiotic, you’ll need to take two tablets per day for seven days. If you still have symptoms after seven days, speak to a doctor or healthcare professional.
This treatment requires an online consultation for review by our medical team. The decision to supply the specific treatment and quantity requested will be based on whether our medical team are satisfied that it will be safe, appropriate, and effective.
About Metronidazole 400mg Tablets
Metronidazole 400mg tablets contain an antibiotic called Metronidazole. They are only available on prescription. This means you’ll need to have a consultation with a medical professional before you can access the medication.
Metronidazole is commonly used to treat infections such as bacterial vaginosis and trichomoniasis, a sexually transmitted disease that can be caught by both men and women.
The active ingredient in the tablets is an antibiotic called Metronidazole. It works by attacking and killing the bacteria that are causing your infection.
How Does Metronidazole Work?
Metronidazole works by entering the bacteria or parasites that are behind your infection and disrupting their DNA. This prevents them from reproducing and eventually kills them.
The antibiotic is particularly effective against the parasite that causes trichomoniasis and the bacteria that cause bacterial vaginosis. It can also be used to treat infected insect bites, bed sores, skin ulcers, infected gums, dental abscesses and pelvic inflammatory disease.
How To Take Metronidazole Tablets
If you’re prescribed Metronidazole to treat an infection, you’ll need to take one 400mg tablet twice a day for seven days. Take Metronidazole with food, or just after you’ve eaten, to reduce the chance of stomach upset.
It’s very important to take your course of Metronidazole for the full seven days, even if your symptoms improve. If you stop taking the medication early, your infection may return and you could have to start treatment all over again.
Metronidazole may interact with alcohol to cause unpleasant side effects like nausea, vomiting, flushing and a rapid heartbeat. Avoid alcohol while taking Metronidazole and for 48 hours after completing treatment to minimise these symptoms.
Ingredients
Metronidazole is the active ingredient in Metronidazole 400mg tablets. The medication also contains a number of inactive ingredients including croscarmellose sodium, cellulose, colloidal silica, lactose, magnesium stearate, maize starch and hypromellose. They also contain coating ingredients such as polyethylene glycol and titanium dioxide.
If you’ve previously had an allergic reaction to any of these ingredients, Metronidazole may not be right for you. Speak to your doctor or pharmacist about the other medications available.
Side Effects
Like all medications, Metronidazole may cause some side effects. For most people, these side effects are mild and disappear once they complete their treatment.
If you’re taking Metronidazole, you may find you have an upset stomach, nausea or a metallic taste in your mouth. You could also experience tingling in your arms and legs, headaches and dizziness, though these symptoms are less common.
If you have an allergic reaction to Metronidazole – for example, you develop blistering or peeling of the skin, a skin rash, sores, ulcers or a fever – contact your doctor straight away.
Warnings
Metronidazole isn’t suitable for everyone. If you’ve ever had liver problems, have a disease of the nervous system, or are having kidney dialysis, you may not be able to take Metronidazole.
Metronidazole could interact with lithium, epilepsy medications and anticoagulants like Warfarin. Avoid alcohol while taking Metronidazole and for two days after completing your treatment.
Metronidazole may not be suitable if you’re breastfeeding, pregnant or planning to become pregnant.
Do not drive if you experience drowsiness or blurred vision when taking Metronidazole.
It’s essential you tell your doctor about any prescription medications you take, and any pre-existing medical conditions you have, during your consultation.

Metronidazole 400mg Tablets FAQs
What Is Trichomoniasis And How Is It Treated?
Trichomoniasis, also known as trich, is a sexually transmitted disease that’s caused by a parasite called trichomonas vaginalis.
You can catch (and spread) trichomoniasis by having unprotected sex or by sharing sex toys with another person. The main symptoms of the infection are an abnormal discharge from the genitals (penis or vagina), pain in your genitals and pain when urinating.
Only 30% of people with trichomoniasis will experience symptoms. This means you could have the infection and pass it on to others without knowing it.
Metronidazole 400mg is one of the most effective treatments for trichomoniasis. If you have trich, your doctor will probably prescribe two Metronidazole 400mg tablets per day for seven days. This week-long course of Metronidazole 400mg typically clears a trich infection completely.
How Quickly Does Metronidazole Work For Trichomoniasis?
Metronidazole 400mg acts quickly against trich. You may see improvements in your symptoms just 24 to 48 hours after starting treatment with Metronidazole.
However, even if your symptoms disappear completely, it’s important that you complete the full seven-day course of antibiotics. If you stop taking Metronidazole early, your infection could return, and you may have to start treatment all over again.
Why Can't I Drink Alcohol While Taking Metronidazole?
Alcohol interacts with Metronidazole. If you drink while taking Metronidazole, you could experience a number of side effects including nausea, vomiting, flushing, headaches and a rapid heartbeat.
If you’re prescribed Metronidazole, it’s important you avoid alcohol while taking the medication and for at least 48 hours after you take your last tablet.
Can Metronidazole Treat Other Infections Besides Trichomoniasis?
Metronidazole is best-known as a treatment for trichomoniasis, however it can be used to treat a number of infections including bacterial vaginosis, dental infections and skin ulcers. It can also be used to treat stomach ulcers that are caused by a bacteria called H. pylori, and certain parasitic infections like giardiasis and amoebiasis.
You should only take Metronidazole if it’s been prescribed to you by a doctor. They’ll be able to diagnose your condition and ensure that the antibiotic is the right choice for you.
Can I Take Metronidazole During Pregnancy Or While Breastfeeding?
There’s no strong evidence to show that Metronidazole could cause harm during pregnancy or breastfeeding. However, it’s possible that small amounts of the antibiotic could pass to your baby. So, if you are pregnant or breastfeeding, it’s essential that you only take Metronidazole if it’s been prescribed to you by a doctor.
In some cases, your doctor may recommend that you temporarily stop breastfeeding while you take your course of Metronidazole.
Will Metronidazole Affect My Contraception?
Metronidazole hasn’t been shown to interfere with any type of contraception. However, in rare cases it can cause severe vomiting. This could impact how well your body absorbs an oral contraceptive (the pill) and could make it less effective.
If you experience vomiting when taking Metronidazole, it’s a good idea to use additional protection, such as a condom, when having sex.
Although Metronidazole is used to treat sexually transmitted diseases (STIs), it won’t stop you from catching them. You’ll still need to use additional protection when taking Metronidazole to avoid getting any new STIs.
Do I Need To Inform My Sexual Partners If I Have Trichomoniasis?
Yes, if you have trichomoniasis, you’ll need to get in touch with your sexual partners so they can get tested. This is important as a lot of people don’t have symptoms, so your partners may not know they’re infected and could pass the disease on to others.
It’s important that you’re treated for trichomoniasis at the same time as your current sexual partner or partners. It’s also a good idea to avoid sex until your treatment is complete and your infection is cleared. This helps to prevent reinfection and allows for a full recovery.
How Do I Prevent Getting Trichomoniasis Again?
There are a number of steps you can take to protect yourself from catching trichomoniasis and other STIs in the future. One of the most effective is to use a condom during sexual activity.
Limiting sexual partners and getting tested for STIs on a regular basis could help to prevent infection and ensure you spot any diseases that you do catch quickly.
It’s important to remember that you can catch trichomoniasis again, even if you’ve been successfully treated for the disease.
Can I Take Metronidazole With Other Medications?
Metronidazole can interact with other medications. So, it’s essential you tell your doctor about all of the medicines you take during your consultation. This includes herbal remedies and over-the-counter products.
Metronidazole is known to interact with anticoagulants like Warfarin. Metronidazole may also be unsuitable if you take lithium or certain epilepsy medications.
What Should I Do If I Miss A Dose Of Metronidazole?
If you forget to take a Metronidazole 400mg tablet, take it as soon as you remember. However, if it’s nearly time for your next dose, you should skip the missed dose and continue your course of antibiotics as normal.
Never take two tablets at the same time as this could increase the chance of side effects. If you often forget to take your dose of Metronidazole, you could try setting an alarm to remind you.
