Flagyl is the original brand name for metronidazole, an antibiotic and antiprotozoal medicine that works against anaerobic bacteria and certain parasites. In UK clinical practice it is widely used for acute dental infections involving anaerobic bacteria, including dental abscesses, pericoronitis around wisdom teeth and acute necrotising ulcerative gingivitis. It is also a standard treatment option for bacterial vaginosis, trichomoniasis and giardiasis, subject to clinical assessment and local antimicrobial guidance.
Online access is particularly useful when symptoms are distressing and a routine appointment is not available. Many UK patients search to get Flagyl for dental infections, bacterial vaginosis & giardia online UK no GP appointment because NHS GP surgery appointment slots can be limited, and urgent dental appointments may be difficult to obtain at short notice. A responsible online clinic does not bypass safety checks; it replaces the paper prescription pathway with a structured medical questionnaire reviewed by a qualified UK prescriber.
Flagyl 200mg tablets may be supplied in packs of 14, 21, 30 or 60 tablets, depending on the assessed condition, intended course length and prescriber judgement. For several UK regimens, the clinically recommended dose is 400mg per dose, which can be achieved using either one 400mg tablet or two 200mg tablets. Your label will state the exact dose, frequency and duration you must follow.

Ordering Flagyl online in the UK is designed to be quick, but it must still be clinically robust. A reputable online pharmacy will ask about your symptoms, how long they have been present, whether you have fever, swelling, pelvic pain, pregnancy, recent antibiotic use, allergies and any medicines such as warfarin or lithium. This helps the prescriber decide whether metronidazole is appropriate or whether you need urgent face-to-face assessment.
For dental infections, metronidazole may be suitable when anaerobic infection is suspected, particularly where there is gum swelling, dental abscess, pericoronitis or severe wisdom-tooth infection. However, antibiotics do not remove the source of a dental abscess. You should still arrange dental care for drainage, extraction, root canal treatment or local measures if needed.
For BV, metronidazole is one of the main recommended treatments in UK guidance. Online prescribing is most appropriate when symptoms are typical, such as thin grey-white discharge and fishy odour, and there are no red flags such as pelvic pain, pregnancy concerns, abnormal bleeding or possible sexually transmitted infection requiring testing. For giardiasis or persistent diarrhoea after travel, a prescriber may ask additional questions or advise stool testing depending on the clinical picture.
The online process is especially relevant for patients searching order Flagyl online UK next day delivery. If your consultation is approved before the cut-off time, the prescription can be generated internally and the medicine dispatched without you needing to collect a GP paper prescription or attend an 8am phone queue at your GP surgery.
The metronidazole 200mg tablets UK price varies depending on whether you obtain it through the NHS, a private clinic, a high-street walk-in provider or a direct online pharmacy. In England, an NHS prescription normally carries the standard NHS prescription charge of £9.90 per item, unless you are exempt. Private walk-in services may charge a consultation fee as well as the medicine cost, while online services often include the prescriber review and private prescription fee within the displayed treatment price.
Online direct supply can be cost-effective because generic metronidazole is inexpensive, and the prescription is issued electronically to the dispensing pharmacy after approval. The important safety point is that a very low price should never mean skipping clinical checks. A legitimate UK service will be operated by or connected to a GPhC-registered pharmacy and will use UK-registered prescribers.

Your dose depends on the condition being treated, your age, pregnancy status, liver function, other medicines and the prescriber’s assessment. The following reflects common UK BNF and NICE-aligned adult regimens, but your pharmacy label is the instruction you must follow.
For bacterial vaginosis or trichomoniasis, a common adult regimen is metronidazole 400mg twice daily for 5 to 7 days. If supplied as Flagyl 200mg tablets, this may mean taking two 200mg tablets per dose, twice daily, for the prescribed course. For acute dental abscess or pericoronitis, a typical adult regimen is 400mg three times daily for 3 to 5 days, again meaning two 200mg tablets per dose if the 200mg strength is supplied.
Swallow the tablets with water during or after food. Taking metronidazole with food can reduce nausea and stomach upset. Complete the full course unless a clinician tells you to stop, even if symptoms begin to improve after 24–48 hours.
| Clinical Scenario / Target Condition | Recommended Dose & Course Length | Food / Timing / Administration Rule | Key BNF Precautions & Interacting Medicines |
|---|---|---|---|
| Bacterial vaginosis (BV) | Common adult regimen: 400mg twice daily for 5 to 7 days; with 200mg tablets this is usually two tablets per dose | Swallow with water during or after food; space doses evenly | Avoid alcohol during treatment and for at least 48 hours after; check pregnancy and breastfeeding status |
| Trichomoniasis | Common adult regimen: 400mg twice daily for 5 to 7 days; partner testing and treatment may be required | Take as directed and avoid missed doses; sexual health testing may be advised | Important interactions include warfarin, lithium and 5-fluorouracil |
| Acute dental abscess / pericoronitis | Common adult regimen: 400mg three times daily for 3 to 5 days | Take after food where possible; arrange dental review to treat the source | Urgent care is needed for spreading facial swelling, difficulty swallowing, fever, or breathing problems |
| Giardiasis | Regimen varies by clinical assessment and local guidance; prescriber will specify dose and duration | Maintain fluids if diarrhoea is present; take tablets with food if nauseous | Seek advice for blood in stools, severe dehydration, persistent fever, or recent high-risk travel |
Flagyl 200mg tablets are oral tablets containing metronidazole. Generic metronidazole tablets are medically equivalent when supplied to the same UK quality standards and may be dispensed instead of the brand depending on availability and prescribing choice. Both branded and generic products supplied by a legitimate UK pharmacy should be MHRA-approved or UK-licensed where applicable.
Typical online pack sizes include 14, 21, 30 or 60 tablets. The most appropriate pack size depends on the dose and duration required. For example, a 5–7 day BV course using 400mg twice daily may require 20–28 of the 200mg tablets if the 200mg strength is used, whereas a dental infection regimen of 400mg three times daily for 3–5 days may require 18–30 of the 200mg tablets. This is why a prescriber review is needed before supply.
Do not use leftover metronidazole from a previous episode without clinical review. Similar symptoms can be caused by different conditions, including sexually transmitted infections, thrush, inflammatory bowel disease, viral gastroenteritis or dental problems requiring urgent local treatment rather than antibiotics alone.
Discreet delivery is a major reason patients choose online pharmacy supply, particularly for BV, trichomoniasis or giardia-related symptoms. Approved orders are packed in plain unmarked packaging with no visible reference to Flagyl, metronidazole or the treatment indication on the outside of the parcel.
For orders approved before 3:00pm Monday–Friday, same-day dispatch may be available using Royal Mail Tracked 24. Express courier options may also be available to major UK locations including Bristol, Liverpool, Sheffield, Newcastle, Cardiff and Belfast. Delivery times can vary due to courier performance, local sorting delays, bank holidays and address accuracy, so urgent red-flag symptoms should not wait for postal delivery.
If you have rapidly worsening facial swelling, difficulty breathing or swallowing, high fever, severe pelvic pain, signs of dehydration, confusion, blood in stools, or symptoms in pregnancy, you should seek urgent NHS 111, GP, dental emergency or A&E advice rather than relying on next-day medication delivery.
The most important safety rule with Flagyl is the strict zero-alcohol warning. Do not drink alcohol during treatment and for at least 48 hours after finishing metronidazole. Alcohol can trigger a severe disulfiram-like reaction with flushing, vomiting, headache, abdominal cramps, palpitations and tachycardia.
Common side effects include nausea, a metallic taste, reduced appetite, abdominal discomfort, diarrhoea and headache. Less commonly, metronidazole can cause dizziness, rash, dark urine, mouth soreness or changes in liver tests. Stop and seek urgent medical advice if you develop signs of allergy such as facial swelling, wheezing, widespread rash, blistering skin, severe diarrhoea, numbness, tingling, unsteadiness, confusion or seizures.
Key BNF interactions include warfarin, where metronidazole can increase anticoagulant effect and bleeding risk; lithium, where levels may rise and toxicity can occur; and 5-fluorouracil, where toxicity may be increased. You should also tell the prescriber about epilepsy medicines, disulfiram, ciclosporin, busulfan, liver disease, blood disorders, pregnancy, breastfeeding and any recent antibiotic reactions.
Metronidazole may be used in pregnancy or breastfeeding in certain circumstances, but this must be assessed carefully. If you are pregnant, trying to conceive, breastfeeding, immunocompromised, under specialist care, or have recurrent symptoms, the online clinician may request further information or advise a face-to-face review.
Yes, you can order through a UK online clinic without already having a paper GP prescription, provided a UK-registered prescriber reviews your medical questionnaire and approves treatment. Flagyl is still a Prescription Only Medicine, so it is not truly “over the counter”; the private prescription is issued electronically to the pharmacy if it is safe and appropriate.
Online prices may start from around £0.33 per tablet, with starter packs from approximately £17.16, and the consultation and private prescription fee may be included at £0.00. By comparison, an NHS prescription in England is usually £9.90 per item unless you are exempt, while private walk-in clinics may charge both a consultation fee and the medicine cost.
For BV or trichomoniasis, a common UK adult regimen is 400mg twice daily for 5 to 7 days. For acute dental abscess or pericoronitis, a typical adult regimen is 400mg three times daily for 3 to 5 days; giardiasis dosing varies and should be confirmed by the prescriber. If using 200mg tablets, a 400mg dose usually means taking two tablets at a time.
Swallow the tablets with water during or after food to reduce stomach upset. Take doses evenly through the day and complete the full course unless a clinician advises otherwise. Do not drink alcohol during treatment or for at least 48 hours after your final dose.
Many people notice improvement within 24–72 hours, depending on the infection and whether the underlying cause has been addressed. Dental abscesses often need dental treatment as well as antibiotics, and BV or diarrhoeal symptoms should be reassessed if they do not improve or keep returning.
Approved orders placed before the weekday cut-off can usually be dispatched the same day using Royal Mail Tracked 24, with express courier options available in many UK areas. Parcels are sent in plain unmarked packaging with no treatment name visible on the outside.
The most important warning is to avoid all alcohol during treatment and for at least 48 hours afterwards because of a possible severe disulfiram-like reaction. Tell the prescriber if you take warfarin, lithium, 5-fluorouracil or other regular medicines, or if you have liver disease, blood disorders, neurological symptoms, pregnancy or breastfeeding considerations.
