You should seek the advice of your veterinarian if your pet is ill as only he or she can correctly advise on the diagnosis and recommend the treatment that is most appropriate for your pet.

Phenylbutazone is widely used in veterinary practice. This drug can significantly affect laboratory results making interpretation difficult

Phenylbutazone is widely used in veterinary medicine but it can interfere with laboratory tests resulting in abnormal results which are difficult to interpret, including :

• Haematology
  • Decreased packed cell volume (PCV)
  • Decreased neutrophil count
  • Decreased platelet count
  • Increased clotting time
• Blood Chemistry
  • Increased urea
  • Increased creatinine

Clinicians should be aware of these possible changes when interpreting laboratory results from samples taken from animals being treated with phenylbutazone
