Hydrocortisone for Dogs and Cats: Uses, Dosage and Side Effects

Hydrocortisone for dogs and cats is a corticosteroid in the class of drugs called glucocorticoids. It is a synthetic version of cortisol, a hormone produced by the body's adrenal glands. Hydrocortisone is commonly used for skin allergies, inflammatory conditions, adrenal insufficiency, and certain immune-mediated diseases.

Hydrocortisone for dogs works by suppressing the body's inflammatory response and calming overactive immune activity. When applied topically, it blocks the activation of skin proteins that trigger inflammation, reducing redness, swelling, and itching at the site of application. When given as an injection or an oral tablet, it has a broader systemic effect, reducing inflammation across multiple organ systems and, in dogs with Addison's disease, replacing cortisol that the adrenal glands can no longer produce.

Hydrocortisone for cats works the same way, reducing localised or systemic inflammation depending on the form used.

Topical Hydrocortisone is sometimes used off-label in cats (used outside its originally approved indication), which is common in veterinary medicine.

The Hydrocortisone dosage for dogs depends on the form prescribed and the condition being treated. For topical preparations, apply a thin layer to the affected area every 6 to 12 hours, as directed by the vet. Dogs should be prevented from licking the application site for at least 20 to 30 minutes after each application.

For oral anti-inflammatory use, the general dose is 0.5 mg/kg given every 12 hours. For maintenance management of Addison's disease, the oral dose is typically 0.125 mg/kg every 12 hours. Oral Hydrocortisone should be given with food to reduce the risk of stomach upset and gastric ulcers.

Large breeds with Addison's disease may need higher absolute oral doses. In an acute Addisonian crisis, injectable Hydrocortisone is administered in a hospital.

The Hydrocortisone dosage for cats in topical form is similar to that for dogs. A thin layer is applied to the affected skin every 6 to 12 hours.

Cats with ear inflammation receiving Hydrocortisone-containing ear drops should first be examined by a cat doctor to confirm the eardrum is intact. This is because applying drops into an ear with a ruptured eardrum can cause serious complications, including hearing loss.

Most side effects depend on the form used and the duration of treatment.

Hydrocortisone is a useful corticosteroid medication that helps manage inflammation, allergies, and certain hormone deficiencies in dogs and cats. However, because steroids affect multiple body systems, they should always be used carefully and under veterinary supervision.
