Corticosteroid use in neurology: how dogs are referrals to a neurology service?

Abstract

Corticosteroids are drugs widely used in veterinary neurology due to their recognized anti-inflammatory, immunosuppressive and analgesic effects. However, their use in high doses and for long term may result in undesirable side effects. This study describes the prevalence of dogs with neurologic diseases referred to a veterinary neurology service with previous prescriptions for corticosteroids. In this retrospective study 284 medical records of dogs were evaluated in the period between August 2017 and April 2019. Of these, 194 (68%) dogs had already received medical care from a clinician and 100 (52%) had previously been prescribed corticosteroids. After diagnosis at the reference service, the corticosteroid dose was suspended in 28% of the cases, adjusted in 41% and maintained in 31%. Dogs receiving immunosuppressive doses were the most affected and in 71% and 21% of the cases, their medication was adjusted or suspended, respectively. In conclusion, the therapy for neurological diseases is still strongly associated with the indiscriminate use of corticosteroids, without the dosage correlated to the desired effect.
