🎯 Indications and Usage ▾
INDICATIONS AND USAGE Metronidazole vaginal gel is indicated in the treatment of bacterial vaginosis (formerly referred to as Haemophilus vaginitis, Gardnerella vaginitis, nonspecific vaginitis, Corynebacterium vaginitis, or anaerobic vaginosis). NOTE For purposes of this indication, a clinical diagnosis of bacterial vaginosis is usually defined by the presence of a homogeneous vaginal discharge that (a) has a pH of greater than 4.5, (b) emits a "fishy" amine odor when mixed with a 10% KOH solution, and (c) contains clue cells on microscopic examination.
Gram's stain results consistent with a diagnosis of bacterial vaginosis include (a) markedly reduced or absent Lactobacillus morphology, (b) predominance of Gardnerella morphotype, and (c) absent or few white blood cells. Other pathogens commonly associated with vulvovaginitis, e.g., Trichomonas vaginalis , Chlamydia trachomatis , N. gonorrhoeae , Candida albicans , and Herpes simplex virus should be ruled out.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION The recommended dose is one applicator full of metronidazole vaginal gel (approximately 5 grams containing approximately 37.5 mg of metronidazole) intravaginally once or twice a day for 5 days. For once-a-day dosing, metronidazole vaginal gel should be administered at bedtime.
⛔ Contraindications ▾
CONTRAINDICATIONS Metronidazole vaginal gel is contraindicated in patients with a prior history of hypersensitivity to metronidazole, parabens, other ingredients of the formulation, or other nitroimidazole derivatives.
⚠️ Warnings ▾
WARNINGS Convulsive Seizures and Peripheral Neuropathy Convulsive seizures and peripheral neuropathy, the latter characterized mainly by numbness or paresthesia of an extremity, have been reported in patients treated with oral or intravenous metronidazole. The appearance of abnormal neurologic signs demands the prompt discontinuation of metronidazole vaginal gel therapy. Metronidazole vaginal gel should be administered with caution to patients with central nervous system diseases.
Psychotic Reactions Psychotic reactions have been reported in alcoholic patients who were using oral metronidazole and disulfiram concurrently. Metronidazole vaginal gel should not be administered to patients who have taken disulfiram within the last 2 weeks.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS Clinical Trials There were no deaths or serious adverse events related to drug therapy in clinical trials involving 800 non-pregnant women who received metronidazole vaginal gel. In a randomized, single-blind clinical trial of 505 non-pregnant women who received metronidazole vaginal gel once or twice a day, 2 patients (one from each regimen) discontinued therapy early due to drug-related adverse events. One patient discontinued drug because of moderate abdominal cramping and loose stools, while the other patient discontinued drug because of mild vaginal burning.
These symptoms resolved after discontinuation of drug. Medical events judged to be related, probably related, or possibly related to administration of metronidazole vaginal gel once or twice a day were reported for 195/505 (39%) patients. The incidence of individual adverse reactions were not significantly different between the two regimens.
Unless percentages are otherwise stipulated, the incidence of individual adverse reactions listed below was less than 1%: Reproductive: Vaginal discharge (12%), Symptomatic Candida cervicitis/vaginitis (10%), Vulva/vaginal irritative symptoms (9%), Pelvic discomfort (3%). Gastrointestinal: Gastrointestinal discomfort (7%), Nausea and/or vomiting (4%), Unusual taste (2%), Diarrhea/loose stools (1%), Decreased appetite (1%), Abdominal bloating/gas; thirsty, dry mouth. Neurologic: Headache (5%), Dizziness (2%), Depression.
Dermatologic: Generalized itching or rash. Other: Unspecified cramping (1%), Fatigue, Darkened urine. In previous clinical trials submitted for approved labeling of metronidazole vaginal gel the following was also reported: Laboratory: Increased/decreased white blood cell counts (1.7%).
Other Metronidazole Formulations Other effects that have been reported in association with the use of topical (dermal) formulations of metronidazole include skin irritation, transient skin erythema, and mild skin dryness and burning. None of these adverse events exceeded an incidence of 2% of patients. Metronidazole vaginal gel affords minimal peak serum levels and systemic exposure (AUC) of metronidazole compared to 500 mg oral metronidazole dosing.
Although these lower levels of exposure are less likely to produce the common reactions seen with oral metronidazole, the possibility of these and other reactions cannot be excluded presently. The following adverse reactions and altered laboratory tests have been reported with the oral or parenteral use of metronidazole: Cardiovascular : Flattening of the T-wave may be seen in electrocardiographic tracings. Central Nervous System : (See WARNINGS .) Headache, dizziness, syncope, ataxia, confusion, convulsive seizures, peripheral neuropathy, vertigo, incoordination, irritability, depression, weakness, insomnia.
Gastrointestinal : Abdominal discomfort, nausea, vomiting, diarrhea, an unpleasant metallic taste, anorexia, epigastric distress, abdominal cramping, constipation, "furry" tongue, glossitis, stomatitis, pancreatitis, and modification of taste of alcoholic beverages. Genitourinary : Overgrowth of Candida in the vagina, dyspareunia, decreased libido, proctitis. Hematopoietic : Reversible neutropenia, reversible thrombocytopenia.
Hypersensitivity Reactions : Urticaria; erythematous rash; flushing; nasal congestion; dryness of the mouth, vagina, or vulva; fever; pruritus; fleeting joint pains. Renal : Dysuria, cystitis, polyuria, incontinence, a sense of pelvic pressure, darkened urine.

🔄 Drug Interactions ▾
Drug Interactions Oral metronidazole has been reported to potentiate the anticoagulant effect of warfarin and other coumarin anticoagulants, resulting in a prolongation of prothrombin time. This possible drug interaction should be considered when metronidazole vaginal gel is prescribed for patients on this type of anticoagulant therapy. In patients stabilized on relatively high doses of lithium, short-term oral metronidazole therapy has been associated with elevation of serum lithium levels and, in a few cases, signs of lithium toxicity.
Use of cimetidine with oral metronidazole may prolong the half-life and decrease plasma clearance of metronidazole.
🔄 Drug / Laboratory Test Interactions ▾
Drug/Laboratory Test Interactions Metronidazole may interfere with certain types of determinations of serum chemistry values, such as aspartate aminotransferase (AST, SGOT), alanine aminotransferase (ALT, SGPT), lactate dehydrogenase (LDH), triglycerides, and glucose hexokinase. Values of zero may be observed. All of the assays in which interference has been reported involve enzymatic coupling of the assay to oxidation-reduction of nicotinamide-adenine dinucleotides (NAD + NADH).
Interference is due to the similarity in absorbance peaks of NADH (340 nm) and metronidazole (322 nm) at pH 7.
🤰 Pregnancy ▾
Pregnancy Teratogenic Effects There has been no experience to date with the use of metronidazole vaginal gel in pregnant patients. Metronidazole crosses the placental barrier and enters the fetal circulation rapidly. No fetotoxicity or teratogenicity was observed when metronidazole was administered orally to pregnant mice at six times the recommended human dose (based on mg/m 2 ); however, in a single small study where the drug was administered intraperitoneally, some intrauterine deaths were observed.
The relationship of these findings to the drug is unknown. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, and because metronidazole is a carcinogen in rodents, this drug should be used during pregnancy only if clearly needed.
🧒 Pediatric Use ▾
Pediatric Use Safety and effectiveness in children have not been established.
🆘 Overdosage ▾
OVERDOSAGE There is no human experience with overdosage of metronidazole vaginal gel. Vaginally applied metronidazole gel, 0.75% could be absorbed in sufficient amounts to produce systemic effects. (See WARNINGS .)
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Normal Subjects Following a single, intravaginal 5 g dose of metronidazole vaginal gel (equivalent to 37.5 mg of metronidazole) to 12 normal subjects, a mean maximum serum metronidazole concentration of 237 ng/mL was reported (range: 152 ng/mL to 368 ng/mL). This is approximately 2% of the mean maximum serum metronidazole concentration reported in the same subjects administered a single, oral 500 mg dose of metronidazole (mean C max = 12,785 ng/mL, range: 10,013 ng/mL to 17,400 ng/mL). These peak concentrations were obtained in 6 hours to 12 hours after dosing with metronidazole vaginal gel and 1 hour to 3 hours after dosing with oral metronidazole.
The extent of exposure [area under the curve (AUC)] of metronidazole, when administered as a single intravaginal 5 g dose of metronidazole vaginal gel (equivalent to 37.5 mg of metronidazole), was approximately 4% of the AUC of a single oral 500 mg dose of metronidazole (4,977 ng-hr/mL and approximately 125,000 ng-hr/mL, respectively). Dose-adjusted comparisons of AUCs demonstrated that, on a mg to mg comparison basis, the absorption of metronidazole, when administered vaginally, was approximately half that of an equivalent oral dosage.
Patients with Bacterial Vaginosis Following single and multiple 5 g doses of metronidazole vaginal gel to 4 patients with bacterial vaginosis, a mean maximum serum metronidazole concentration of 214 ng/mL on day 1 and 294 ng/mL (range: 228 ng/mL to 349 ng/mL) on day five were reported. Steady-state metronidazole serum concentrations following oral dosages of 400 mg to 500 mg BID have been reported to range from 6,000 ng/mL to 20,000 ng/mL. Microbiology The intracellular targets of action of metronidazole on anaerobes are largely unknown.
The 5-nitro group of metronidazole is reduced by metabolically active anaerobes, and studies have demonstrated that the reduced form of the drug interacts with bacterial DNA. However, it is not clear whether interaction with DNA alone is an important component in the bactericidal action of metronidazole on anaerobic organisms. Culture and sensitivity testing of bacteria are not routinely performed to establish the diagnosis of bacterial vaginosis.
(See INDICATIONS AND USAGE .) Standard methodology for the susceptibility testing of the potential bacterial vaginosis pathogens, Gardnerella vaginalis , Mobiluncus spp . , and Mycoplasma hominis , has not been defined. Nonetheless, metronidazole is an antimicrobial agent active in vitro against most strains of the following organisms that have been reported to be associated with bacterial vaginosis: Bacteroides spp . Gardnerella vaginalis Mobiluncus spp .
Peptostreptococcus spp .
