Following ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

4.2Most important symptoms/effects, acute and delayed

SYMPTOMS: Symptoms of exposure to this chemical may include nerve or sheath structural changes, eye changes, tremors, fever, jaundice and other liver changes. It may cause convulsive seizures, numbness, nausea, vomiting, abdominal discomfort, diarrhea, sharp, unpleasant metallic taste, erythematous rash, pruritus, dizziness, syncope, ataxia, thrombophlebitis after intravenous infusion, darkened urine, anorexia, epigastric distress, constipation, glossitis, stomatitis, reversible thrombocytopenia and vertigo. Flattening of the T-wave may be seen in electrocardiographic tracings. It may also cause incoordination, irritability, depression, weakness, insomnia, nasal congestion dysuria, cystitus, polyuria, incontinence, a sense of pelvic pressure, dyspareunia, decrease of libido, proctitis and fleeting joint pains sometimes resembling serum sickness. It may cause skin rash and drowsiness. Other symptoms of exposure include malaise, transient rashes, gastrointestinal disturbances and peripheral neuropathy. It may cause coated tongue, dry mouth, urethral discomfort, temporary leukopenia, increase in chromosome aberrations, candidal vaginitis, lethargy and sore furred tongue. In conjunction with alcohol it may provoke a disulfuram-like reaction. Pregnant women expose to this compound have given birth to premature, stillborn infants. One infant has died of white asphyxia. It may cause epigastric distress, abdominal cramping, numbness or paresthesia of an extremity, urticaria, flushing, dryness of vagina or vulva, abdominal distress, headache (if ingested with alcohol), confusional and psychotic states, blood dyscrasias, temporary neutropenia which reverses after therapy, and low concentrations of lipids in plasma. ACUTE/CHRONIC HAZARDS: This compound is harmful by ingestion, inhalation or skin absorption. It may cause irritation. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and nitrogen oxides. (NTP, 1992)

4.3Indication of immediate medical attention and special treatment needed, if necessary

Maintain an open airway and assist ventilation if necessary. Treat coma, seizures, hypotension, anaphylaxis, and hemolysis if they occur. Replace fluid losses resulting from gastroenteritis with intravenous crystalloids. ... Administer activated charcoal. Gastric emptying is not necessary if activated charcoal can be given promptly. Most antibiotics are excreted unchanged in the urine, so maintenance of adequate urine flow is important. The role of forced diuresis is unclear. Hemodialysis is not usually indicated, except perhaps in patients with renal dysfunction and a high level of toxic agent. Antibacterial Agents

SECTION 10: Stability and reactivity

10.1Reactivity

no data available

10.2Chemical stability

Stable in air but darkens on exposure to light.

10.3Possibility of hazardous reactions

METRONIDAZOLE darkens on exposure to light. This chemical is incompatible with strong oxidizing agents. (NTP, 1992).

10.4Conditions to avoid

no data available

10.5Incompatible materials

Because reconstituted metronidazole hydrochloride solution has a low pH, the solution may interact with aluminum resulting in a reddish-brown discoloration of the solution. Therefore, aluminum hub needles should not be used to reconstitute the drug or to transfer the reconstituted solution to the diluting fluid. Metronidazole hydrochloride that has been reconstituted, diluted, and neutralized and metronidazole injection do not interact with aluminum when administered over the time period specified by the manufacturers; however, some discoloration of these solutions may occur when they are in contact with aluminum for periods of 6 hours or longer.

SECTION 12: Ecological information

12.1Toxicity

• Toxicity to fish: LC50 Lepomis macrochirus (Bluegill sunfish, weight 0.1g) >100 ppm/96 hr; static /99.4% AI formulated product
• Toxicity to daphnia and other aquatic invertebrates: EC50 Daphnia magna (Water flea, age <24 hr; intoxication, immobilization) >1000 ppm/48 hr; static /99% AI formulated product
• Toxicity to algae: EC50 Pseudokirchneriella subcapitata (Green algae; decreased population growth) 40.4 mg/L/72 hr (95% confidence limit: 2.17-750 mg/L); static
• Toxicity to microorganisms: no data available

12.2Persistence and degradability

AEROBIC: The biodegradation half-lives in sandy soil-manure slurry were 9.7 to 14.7 days and in clay soil-manure slurry were 13.1 to 26.9 days(1). Metronidazole was found to be non-degradable in sewage treatment conditions(2). Metronidazole did not degrade in closed bottle tests at concentrations of 5.95 ug/L and 5.95 mg/L(3).

12.3Bioaccumulative potential

An estimated BCF of 3 was calculated for metronidazole(SRC), using a log Kow of -0.02(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4Mobility in soil

The Koc of metronidazole is estimated as 23(SRC), using a log Kow of -0.02(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that metronidazole is expected to have very high mobility in soil.

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning.
