Special precautions for use

i.

Special precautions for use in animals

Wash and dry udders and teats thoroughly preferably with an individual paper towel just before milking.

Do not mix with any other product.

Do not return any used product to the original container.

Although Blu-Gard Teat Spray contains emollients it is not sold as cure for

badly chapped or inflamed teats. If this condition exists a veterinarian should be consulted.

ii.

Special precautions for the person administering the veterinary medicinal product to animals

Avoid contact with skin and eyes.

In case of accidental exposure, wash the affected area with plenty of clean running water and seek medical attention if irritation persists.

People who are allergic to ingredients in the product should handle the product with great care (e.g. by wearing rubber gloves).

Avoid working in spray mist.

Wash hands after use.

Do not eat, drink or smoke whilst using this product.

Keep away from food, drink and animal feedstuffs.

iii.

Other precautions

None.

4.6

Adverse reactions (frequency and seriousness)

None.

4.7

Use during pregnancy, lactation or lay

The product is indicated specifically for use during lactation. No residues have been detected in milk. As no absorption has been detected from skin no effects on reproduction or on the foetus would be expected nor have they been observed.

4.8

Interaction with other medicinal products and other forms of interaction

None known.

4.9

Amount(s) to be administered and administration route

Immediately after milking spray each teat with full strength, undiluted Blu-Gard Teat Spray. Approximately 16ml of Blu-Gard Teat Spray per cow per milking should be used. Allow teats to air dry. Do not wipe. Just prior to next milking wash entire udder and teats thoroughly preferably with an individual paper towel.

4.10

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

Not applicable.

Visual identification of sprayed teats is facilitated by the inclusion of dyes in the product.

No adverse effects of repeated spraying would be expected as absorption through skin is negligible.

The product does not require dilution therefore application of Blu-Gard Teat Spray at excessive concentrations is not possible.

4.11

Withdrawal period(s)

Cattle: Meat – zero days

Milk – zero hours

PHARMACOLOGICAL PROPERTIES

ATCvet Code: QG52A

5.1

Pharmacodynamic properties

The active ingredient of Blu-Gard Teat Spray, sodium dodecylbenzene sulphonate, is an anionic surfactant, bactericidal against Gram-positive and Gram-negative organisms with maximum activity in acid solution. The exact mechanism of its antibacterial action is not fully elucidated but dissolution of the cell wall and lysis of the phospholipid material of the protoplasmic membrane with disorganisation of the permeability barrier of the cell is involved. This results in cytological damage and leakage of metabolites.

Sodium hydroxide and citric acid are included as a citric acid/citrate buffer to maintain the pH in the acid range of 2.8 to 3.2 (optimum pH 3).

Glycerine and Sorbitol act as emollients. They soothe, smooth and hydrate the skin. They form an occlusive film on the stratum corneum and prevent drying from evaporation of water which has diffused from the underlying layers of skin. Glycerol is extensively used as a vehicle for drugs applied to the skin.

Patent Blue V (E131) and Amaranth (E123), food grade dyestuffs, are included to colour the product and identify its presence on teats.

Carmellose is included as a thickener to increase persistence of the product on the surface of the teat and prolong the availability there of the antibacterial action of the product.

5.2

Pharmacokinetic properties

Penetration of anionic surfactants through skin is poor. No penetration of rat skin or of human skin up to 24 hours after application has been detected.

Alkyl benzene sulphonates (including dodecyl benzene sulphonate) are readily absorbed from the intestinal tract of mammals, metabolised to sulphophenyl carboxylic acids and excreted in bile and urine.

5.3

Environmental properties

None.
