1. What Is Hydrocortisone?

Hydrocortisone is a glucocorticoid steroid commonly used in veterinary medicine for its strong anti‑inflammatory and anti‑itch properties :contentReference[oaicite:3]{index=3}. Available in topical, injectable and oral forms, it's used to manage conditions ranging from skin irritation to adrenal crises.

2. Forms & Formulations

• Topical: creams, sprays, shampoos, ointments, ear drops—OTC versions <1%, prescription ≥1% :contentReference[oaicite:4]{index=4}.
• Injectable: used in emergencies like Addisonian (hypoadrenocorticism) crises :contentReference[oaicite:5]{index=5}.
• Oral: sometimes compounded for Addison’s disease, though not routinely used in dogs :contentReference[oaicite:6]{index=6}.

Note: compounded medications are tailored to your pet’s needs but are not FDA‑approved :contentReference[oaicite:7]{index=7}.

3. How It Works

Hydrocortisone dampens inflammatory pathways by inhibiting proteins that drive swelling and itching when applied topically :contentReference[oaicite:8]{index=8}. Systemic forms supplement cortisol quickly during an Addisonian crisis.

4. Common Use Cases

• Skin Irritation: solves itchiness and inflammation from allergies or contact dermatitis.
• Ear Infections: hydrocortisone ear drops (0.5–1%) help soothe itchy ears :contentReference[oaicite:9]{index=9}.
• Addisonian Crises: injectable forms provide urgent cortisol in adrenal failure :contentReference[oaicite:10]{index=10}.
• Hot Spots & minor wounds: enzymatic hydrocortisone creams can reduce inflammation :contentReference[oaicite:11]{index=11}.

5. Dosing & Administration Tips

Topical Applications

• Only apply to intact skin – avoid broken or ulcerated areas.
• Stop pets from licking—wait ≥30 minutes until dry :contentReference[oaicite:12]{index=12}.
• For ears, confirm no ruptured eardrum before use :contentReference[oaicite:13]{index=13}.

Oral & Injectable

• Injectables are administered only in clinics.
• Oral forms—usually home‑made—should be given with water; food helps prevent stomach upset :contentReference[oaicite:14]{index=14}.
• If stopping long-term therapy, taper off slowly under vet supervision to avoid adrenal insufficiency :contentReference[oaicite:15]{index=15}.

6. Risks & Side Effects

Even topical use can cause local irritation—redness, hives, peeling :contentReference[oaicite:16]{index=16}. Systemic exposure risks include:

• Thinning skin, increased thirst/urination/appetite, hair loss, muscle loss, pot-bellied appearance :contentReference[oaicite:17]{index=17}.
• Immune suppression—risk of infection or delayed healing :contentReference[oaicite:18]{index=18}.
• GI ulceration: avoid combining with NSAIDs like Rimadyl or Metacam → washout period ~5 days needed :contentReference[oaicite:19]{index=19}.

7. Common Mistakes

• Using human hydrocortisone OTC products—not FDA‑approved for pets :contentReference[oaicite:20]{index=20}.
• Administering without vet guidance—corticosteroids must be prescribed :contentReference[oaicite:21]{index=21}.
• Combining with NSAIDs—raises ulcer risk unless properly spaced :contentReference[oaicite:22]{index=22}.
• Applying to broken skin or puppies—some products contraindicated :contentReference[oaicite:23]{index=23}.

8. Breed‑Specific Notes

Certain breeds—Bulldogs, Boxers, Dalmatians—are prone to yeast infections or allergies and may benefit from tailored doses of topical hydrocortisone. Hydrocortisone may also thin skin faster in thin-coated breeds like Greyhounds or Whippets, so use the mildest effective concentration and shortest duration.

9. Partnering with Your Vet

Work closely with your veterinarian to:

• Choose the right formulation & strength
• Monitor for side effects with regular check-ins
• Co-manage with supportive care: medicated shampoos, fatty acids, allergy management

Tools like Ask A Vet™ consultation, Woopf™ itch sprays, and Purrz™ recovery balms complement hydrocortisone use with safe enrichment and skin barrier support.

10. Ask A Vet App & Services

💡 Ask A Vet offers telehealth support to guide safe corticosteroid use, dosage adjustments, and secondary care like diet or supplements.

Woopf products, available in the app store, provide itch-relief options your vet may recommend alongside topical steroids.

✅ Conclusion

Hydrocortisone remains a powerful ally for managing canine skin and ear inflammation—but like any medication, success hinges on correct use and veterinary partnership. Stay mindful of formulation types, interactions, side effects, and breed needs. With care, your dog can be comfortable, healthy, and thriving in 2025.
