PRESCRIPTION NEEDED (Pom-V)
Masivet tablets for dogs are prescribed for the treatment of specific mast cell tumours. These are a type of skin cancer.
Your vet will confirm whether your dog’s tumour fits the licensed use for Masivet. Blood tests, imaging and sometimes biopsy results are used before starting treatment.
Masivet tablets for dogs form part of a wider cancer care plan. This may include surgery, supportive care and regular monitoring.
When Masivet Tablets for Dogs Are Used
Vets may use Masivet tablets for dogs when:
The mast cell tumour meets the product’s criteria
Surgery alone is not enough or not possible
Ongoing medical management has been advised
Masivet is not suitable for every dog with a mast cell tumour. Careful assessment is vital. Your vet will discuss all options and decide if Masivet is appropriate.
How Masivet Tablets for Dogs Work
Masivet tablets for dogs contain masitinib. Masitinib is a tyrosine kinase inhibitor.
It works by blocking certain signals in cancer cells. These signals help mast cell tumour cells grow and survive. By blocking them, Masivet tablets for dogs can slow or reduce tumour activity in some cases.
Your vet will explain what response they hope to see and how long treatment may continue.
