4.5

Special precautions for use

Special precautions for use in animals

Due to the likely variability (time, geographical) in the occurrence of metronidazole

resistant bacteria, bacteriological sampling and susceptibility testing are

recommended.

Whenever possible, the product should only be used based on susceptibility testing.

Official, national and regional antimicrobial policies should be taken into account

when the veterinary medicinal product is used.

In very rare cases, neurological signs may occur especially after prolonged treatment

with metronidazole.

Special precautions to be taken by the person administering the veterinary medicinal

product to animals

Metronidazole has confirmed mutagenic and genotoxic properties in laboratory

animals as well as in humans. Metronidazole is a confirmed carcinogen in laboratory

animals and has possible carcinogenic effects in humans. However, there is

inadequate evidence in humans for the carcinogenicity of metronidazole.

Metronidazole may be harmful for the unborn child.

Impervious gloves should be worn during administration of the product to avoid skin

and hand-to-mouth contact with the product.

To avoid accidental ingestion, particularly by a child, unused part-tablets should be

returned to the open blister space, inserted back into the outer packaging and kept in

a safe place out of the sight and reach of children. In case of accidental ingestion,

seek medical advice immediately and show the package leaflet or the label to the

physician. Wash hands thoroughly after handling the tablets.

Metronidazole may cause hypersensitivity reactions. In case of known

hypersensitivity to metronidazole, avoid contact with the veterinary medicinal product.

4.6

Adverse reactions (frequency and seriousness)

The following adverse reactions may occur after administration of metronidazole:

vomiting, hepatotoxicity, neutropenia and neurological signs.

The frequency of adverse reactions is defined using the following convention:

-very common (more than 1 in 10 animals treated displaying adverse reaction)

-common (more than 1 but less than 10 animals in 100 animals treated)

-uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

- rare (more than 1 but less than 10 animals in 10,000 animals treated)

-very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

4.7

Use during pregnancy, lactation or lay

Studies in laboratory animals have shown inconsistent results with regard to

teratogenic/embryotoxic effects of metronidazole. Therefore, use of this product

during pregnancy is not recommended. Metronidazole is excreted in milk and use

during lactation is therefore not recommended.

4.8

Interaction with other medicinal products and other forms of interaction

Metronidazole may have an inhibitory effect on the degradation of other drugs in the

liver, such as phenytoin, cyclosporine and warfarin.

Cimetidine may decrease the hepatic metabolism of metronidazole resulting in

increased serum concentration of metronidazole.

Phenobarbital may increase hepatic metabolism of metronidazole resulting in

decreased serum concentration of metronidazole.

4.9

Amounts to be administered and administration route

For oral administration.

The recommended dose is 50 mg metronidazole per kg bodyweight per day, for

5-7 days. The daily dose may be divided equally for twice daily administration

(i.e. 25 mg/kg bodyweight twice daily).

To ensure administration of the correct dosage, bodyweight should be determined as

accurately as possible.

Tablets can be divided into 2 or 4 equal parts to ensure accurate dosing. Place the

tablet on a flat surface, with its scored side facing up and the convex (rounded) side

facing the surface.

Halves: press down with your thumbs or fingers on both sides of the tablet.

Quarters: press down with your thumb or a finger in the middle of the tablet.

The remaining portion(s) should be given at the next administration(s).

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

Adverse events are more likely to occur at doses and treatment durations in excess

of the recommended treatment regimen. If neurological signs occur, treatment should

be discontinued and the patient should be treated symptomatically.

PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: (nitro) imidazole derivatives

ATCvet code: QP51AA01

5.1

Pharmacodynamic properties

After metronidazole has penetrated the bacteria the molecule is reduced by the

sensitive bacteria (anaerobe). The metabolites that are created have a toxic effect on

the bacteria through binding to the bacterial DNA. In general metronidazole is

bactericidal for sensitive bacteria in concentrations equal to or a little higher than the

minimum inhibiting concentration (MIC).

Clinically metronidazole does not have any relevant effect on facultative anaerobes,

obligate aerobes and microaerophilic bacteria.

5.2

Pharmacokinetic particulars

Metronidazole is immediately and well absorbed after oral administration. The peak

plasma concentration, C

was reached in dogs at between 0.75 and 2 hours after

dosing and in cats at between 0.33 and 2 hours after dosing. The average terminal

half life was 6.35 hours in dogs and 6.21 hours in cats. Metronidazole penetrates well

into the tissues and bodily fluids, such as saliva, milk, vaginal secretions and semen.

Metronidazole is primarily metabolised in the liver. Within 24 hours after oral

administration, 35-65% of the administered dose (metronidazole and the metabolites

thereof) is excreted in the urine.
