Vitamin K Tablets for Dogs

  • 50mg » Pack of 14 Tablets £15.49

Vitamin K tablets are usually given to dogs after known, or suspected, consumption of the anti-coagulant type of rodent poison. These poisons act by causing rodents to die of internal bleeding. Vitamin K is able to counteract the effects of the poison, but needs to be given to cover the whole period of time while the poison might be active within the dog. This can be for up to three weeks. It is usual to give the dog an injection of vitamin K at the start of the treatment, then tablets daily for 21 days.

List of excipients:

Tablet core: Silica (colloidal anhydrous), calcium hydrogen phosphate dihydrate, glycerol dibehenate, magnesium stearate, lactose monohydrate, croscarmellose sodium

Film-coated tablet. Oblong tablet, slight yellow with 3 scored lines. The tablet can be divided into equal halves and quarters.

Contraindications, warnings, etc

Do not use in cases of known hypersensitivity to the active substance or to any of the excipients.

Special warnings for each target species: As the anticoagulant effects of rodenticides are known to be long lasting, it is recommended to administer vitamin K1 with an oral formulation for 3 weeks, and to evaluate the coagulation status (via one stage prothrombin times) 48 hours after the last administration. If it is prolonged, the treatment is maintained until the clotting time is normal 48 hours after cessation of treatment to avoid relapse. The duration of treatment can be extended as long as the anticoagulant persists in the body.

Special precautions for use in animals: The formation of prothrombin may be inadequate when dealing with patients with severe liver dysfunction. Therefore, careful monitoring of coagulation parameters after administration of vitamin K1 is required.

Special precautions to be taken by the person administering the veterinary medicinal product to animals: People with known hypersensitivity to phytomenadione should avoid contact with the veterinary medicinal product.

Wash hands after use.

Adverse reactions: None known.

Use only according to the benefit/risk assessment by the responsible veterinarian.

Interactions: Salicylates (NSAIDs) and cephalosporins presenting the N-methyl-thiotetrazole moiety may reduce the effect of vitamin K1, by inhibition of the vitamin K1 recycling.
