In a controlled clinical trial, 557 patients used metronidazole gel, one% and 189 patients used the gel vehicle in one case daily for upwards to 10 weeks. The post-obit table summarizes selected adverse reactions that occurred at a rate of ≥ 1%:

The following boosted adverse experiences have been reported with the topical use of metronidazole: pare irritation, transient redness, metal taste, tingling or numbness of extremities, and nausea.
Post Marketing Feel
The following adverse reaction has been identified during post approval employ of topical metronidazole: peripheral neuropathy. Considering this reaction is reported voluntarily from a population of uncertain size, it is non always possible to reliably guess the frequency or establish a causal relationship to drug exposure.
DRUG INTERACTIONS
Oral metronidazole has been reported to potentiate the anticoagulant effect of coumarin and warfarin, resulting in a prolongation of prothrombin fourth dimension. Drug interactions should be kept in listen when METROGEL (metronidazole) is prescribed for patients who are receiving anticoagulant handling, although they are less likely to occur with topical metronidazole assistants because of depression absorption.
WARNINGS
Included as part of the PRECAUTIONS section.
PRECAUTIONS
Neurologic Disease
Peripheral neuropathy, characterized past numbness or paresthesia of an extremity has been reported in patients treated with systemic metronidazole. Although not evident in clinical trials for topical metronidazole, peripheral neuropathy has been reported with the post approval use. The appearance of abnormal neurologic signs should prompt immediate reevaluation of METROGEL therapy. Metronidazole should be administered with caution to patients with central nervous organisation diseases.
Blood Dyscrasias
Metronidazole is a nitroimidazole; utilize with care in patients with show of, or history of, blood dyscrasia.
Contact Dermatitis
Irritant and allergic contact dermatitis have been reported. If dermatitis occurs, patients may need to discontinue utilise.
Eye Irritation
Topical metronidazole has been reported to crusade tearing of the eyes. Avoid contact with the eyes.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment of Fertility
Metronidazole has shown testify of carcinogenic action in a number of studies involving chronic, oral administration in mice and rats, but non in studies involving hamsters.
In several long-term studies in mice, oral doses of approximately 225 mg/grand²/solar day or greater (approximately 37 times the human topical dose on a mg/m² ground) were associated with an increase in pulmonary tumors and lymphomas. Several long-term oral studies in the rat accept shown statistically significant increases in mammary and hepatic tumors at doses > 885 mg/thou²/solar day (144 times the man dose).
Metronidazole has shown evidence of mutagenic activity in several in vitro bacterial analysis systems. In addition, a dose-related increment in the frequency of micronuclei was observed in mice after intraperitoneal injections. An increase in chromosomal aberrations in peripheral claret lymphocytes was reported in patients with Crohn'south disease who were treated with 200 to 1200 mg/day of metronidazole for 1 to 24 months. However, in another study, no increase in chromosomal aberrations in circulating lymphocytes was observed in patients with Crohn's disease treated with the drug for 8 months.
In ane published written report, using albino hairless mice, intraperitoneal assistants of metronidazole at a dose of 45 mg/1000²/day (approximately 7 times the human topical dose on a mg/m² basis) was associated with an increase in ultraviolet radiations-induced peel carcinogenesis. Neither dermal carcinogenicity nor photocarcinogenicity studies have been performed with METROGEL or any marketed metronidazole formulations.
Use In Specific Populations
Pregnancy
Teratogenic Effects - Pregnancy Category B
There are no adequate and well-controlled studies with the use of METROGEL in meaning women. Metronidazole crosses the placental barrier and enters the fetal circulation rapidly. No fetotoxicity was observed after oral assistants of metronidazole in rats or mice at 200 and 20 times, respectively, the expected clinical dose. Nevertheless, oral metronidazole has shown carcinogenic activity in rodents. Because brute reproduction studies are not always predictive of human response, METROGEL (metronidazole) should exist used during pregnancy only if clearly needed.
Nursing Mothers
Afterwards oral administration, metronidazole is secreted in breast milk in concentrations similar to those found in the plasma. Even though blood levels taken after topical metronidazole application are significantly lower than those achieved after oral metronidazole a decision should exist made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother and the chance to the baby.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established.
Geriatric Apply
Threescore-six subjects aged 65 years and older were treated with metronidazole gel, 1% in the clinical study. No overall differences in rubber or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has non identified differences in responses between the elderly and younger patients, just greater sensitivity of some older individuals cannot be ruled out.
Overdosage & Contraindications
OVERDOSE
At that place are no reported human experiences with overdosage of METROGEL. Topically applied metronidazole can be absorbed in sufficient amount to produce systemic furnishings.
CONTRAINDICATIONS
METROGEL (metronidazole) is contraindicated in patients with a history of hypersensitivity to metronidazole or to any other ingredient in the conception.
CLINICAL PHARMACOLOGY
Mechanism of Action
The mechanism of activeness of metronidazole in the treatment of rosacea is unknown.
Pharmacodynamics
The pharmacodynamics of metronidazole in association with the handling of rosacea are unknown.
Pharmacokinetics
Topical assistants of a one gram dose of METROGEL (metronidazole) to the face of thirteen patients with moderate to severe rosacea in one case daily for 7 days resulted in a mean ± SD Cmax of metronidazole of 32 ± ix ng/mL. The hateful ± SD AUC(0-24) was 595 ± 154 ng*hour/mL. The mean Cmax and AUC(0-24) are less than i% of the value reported for a single 250 mg oral dose of metronidazole. The fourth dimension to maximum plasma concentration (Tmax) was 6-10 hours after topical application.
Clinical Studies
In a randomized, vehicle-controlled trial, 746 subjects with rosacea were treated with metronidazole gel, 1% or gel vehicle in one case daily for 10 weeks. Almost subjects had "moderate" rosacea at baseline. Efficacy was determined by recording reduction in inflammatory lesion counts and success rate in the Investigator Global Assessment (per centum of subjects "clear" and "almost clear" of rosacea at the end of the study). The scale is based on the following definitions:
Table 3: Investigator Global Assessment Scale
| Score | Grade | Definition |
| 0 | Articulate | No signs or symptoms present; at most, mild erythema |
| 1 | Almost Clear | Very mild erythema nowadays. Very few small-scale papules/pustules |
| 2 | Balmy | Mild erythema. Several small papules/pustules |
| three | Moderate | Moderate erythema. Several modest or large papules/pustules, and up to 2 nodules |
| 4 | Astringent | Severe erythema. Numerous small and/or large papules/pustules, up to several nodules |
The results are shown in the following table:
Table four: Inflammatory Lesion Counts and Global Scores in a Clinical Trial of Rosacea
| Metronidazole Gel, i% | Vehicle | |||
| N | Results N (%) | N | Results Due north (%) | |
| Inflammatory lesions | 557 | 189 | ||
| Baseline, mean count | 18.3 | 18.4 | ||
| Week-ten, hateful count | 8.ix | 12.8 | ||
| Reduction | 9.4 (50.seven) | 5.half-dozen (32.six) | ||
| Investigator Global Assessment | 557 | 189 | ||
| Field of study clear or almost clear | 214 (38.42) | 52 (27.51) | ||
| Subject with no change | 159 (28.5) | 77 (forty.seven) | ||
Subjects treated with metronidazole gel, 1% experienced a mean reduction of 9.4 inflammatory lesions in the Calendar week-10 LOCF group, compared to a reduction of 5.6 for those treated with vehicle, or a difference in means of 3.8 lesions.
The contribution to efficacy of individual components of the vehicle has non been established.
