<\/a><\/figure>\n\n\n\nMetronidazole is taken up by susceptible bacteria and protozoa and then chemically \u201cactivated\u201d inside those organisms. Once activated, it damages their DNA and other critical cellular components, preventing them from reproducing and ultimately killing them.<\/p>\n\n\n\n
This targeted mechanism makes metronidazole particularly effective against organisms such as Trichomonas vaginalis<\/em> (which causes trichomoniasis), Gardnerella<\/em> and other bacteria associated with bacterial vaginosis, and anaerobic bacteria in pelvic and intra-abdominal infections. <\/p>\n\n\n\n Because these infections can increase the risk of infertility, pelvic pain, pregnancy complications, and higher HIV transmission, clearing them with effective treatment is an important part of long-term sexual health.<\/p>\n\n\n\n Two of the best-known sexual and reproductive health indications for metronidazole are trichomoniasis and bacterial vaginosis (BV).<\/p>\n\n\n\n The CDC STI guidelines<\/a> recommend metronidazole 500 mg by mouth twice daily for 7 days as first-line therapy for trichomoniasis in women, noting that this regimen improves cure rates compared with a single 2 g dose. A randomized trial in women with trichomoniasis found that the 7-day regimen led to significantly fewer treatment failures and fewer positive follow-up tests than a single 2 g dose.<\/p>\n\n\n\n For BV, both 7-day oral regimens and intravaginal metronidazole<\/a> are widely used and effective. Treating these conditions reduces symptoms like abnormal discharge and odor and may lower the risk of complications such as PID, adverse pregnancy outcomes, and increased susceptibility to HIV and other STIs.<\/p>\n\n\n\n Treating infections like trichomoniasis and BV with metronidazole is an important step in protecting your sexual health, but it\u2019s not a substitute for condoms, HIV prevention strategies, or routine STI testing<\/strong>. <\/p>\n\n\n\n Clearing these infections can reduce vaginal inflammation, abnormal discharge, and odor, which may make sex more comfortable and improve confidence and intimacy with partners.<\/p>\n\n\n\n Most guidelines recommend avoiding sex or using condoms every time until you and any partners have finished treatment, symptoms are gone, and at least 7 days have passed, to cut the risk of reinfection. <\/p>\n\n\n\n Successfully treating trichomoniasis and BV can also lower the risk of pelvic inflammatory disease, pregnancy complications, and higher HIV transmission linked to genital inflammation.<\/p>\n\n\n\n There are a few key behavior points during treatment:<\/p>\n\n\n\n If you also use medications for erectile dysfunction or other sexual health treatments, make sure your prescribing clinician knows all your prescriptions so they can watch for interactions and overlapping side effects.<\/p>\n\n\n\n Metronidazole dosing depends on the infection being treated and the product formulation. <\/p>\n\n\n\n Typical adult oral regimens include:<\/p>\n\n\n\n Many clinicians recommend taking metronidazole with food to reduce stomach upset, and extended-release formulations are usually taken on an empty stomach, exactly as directed. You must complete the entire course\u2014even if symptoms improve early\u2014to reduce the risk of recurrence and antibiotic resistance.<\/p>\n\n\n\n To be sure metronidazole clears your infection, avoid alcohol completely<\/a> during treatment and for at least 48\u201372 hours after your last dose. <\/p>\n\n\n\n Mixing metronidazole with alcohol can trigger a “disulfiram-like reaction<\/a>,” which causes unpleasant symptoms such as flushing, nausea, vomiting, abdominal cramps, headache, and rapid heart rate. <\/p>\n\n\n\n Because reactions can be serious and occur with relatively small amounts of alcohol, experts advise strict avoidance of all obvious and hidden sources, including alcohol-containing medications like cough syrups.<\/p>\n\n\n\n Most people tolerate short courses of metronidazole well, but side effects are not rare. Common reactions include:<\/p>\n\n\n\n These effects are usually mild and resolve after treatment ends. More serious but less common risks include peripheral neuropathy (nerve tingling or numbness), seizures, and rare blood disorders, particularly with prolonged or repeated courses or in people with underlying conditions.<\/p>\n\n\n\n Metronidazole has a U.S. boxed warning<\/a> because high, long-term doses caused cancer in some animal studies, so it\u2019s usually reserved for clearly needed, time-limited courses rather than casual or repeated use. <\/p>\n\n\n\n People who are pregnant, trying to conceive, or breastfeeding<\/strong> should talk with a clinician about timing and dose, since recommendations can differ in early pregnancy and around delivery.<\/p>\n\n\n\n Anyone who develops severe headache, confusion, vision changes, unsteady gait, or persistent numbness or tingling<\/strong> while on metronidazole should seek medical attention promptly.<\/p>\n\n\n\n Metronidazole interacts with several other medications, so a full medication review is important before starting it. <\/p>\n\n\n\n Notable interactions include:<\/p>\n\n\n\n For a complete list of drugs that interact with metronidazole, see the Drugs.com Interaction Checker<\/a>. <\/p>\n\n\n\n Seek medical evaluation if you notice new genital discharge, itching, burning, pelvic pain, pain with sex, or urinary symptoms, especially if you have new or multiple partners. <\/p>\n\n\n\n Testing can identify conditions like trichomoniasis, BV, chlamydia, gonorrhea, or other infections. Metronidazole may be part of the treatment plan if an anaerobic or protozoal cause is found.<\/p>\n\n\n\n Because reinfection is common, many experts recommend retesting for trichomoniasis<\/a> after treatment, especially if you have ongoing risk, and follow-up for BV if symptoms return or never fully resolve. <\/p>\n\n\n\n If you have recurring BV, research shows that many people have symptoms again within 6\u201312 months, and newer studies are exploring whether treating male partners can reduce early recurrence.<\/p>\n\n\n\n Need discreet, doctor-reviewed sexual health treatments?
