1. What Is Tresaderm® & How It Works?

Tresaderm® combines three active components:

• Neomycin sulfate: broad-spectrum antibiotic targeting Staph, Pseudomonas, Proteus :contentReference[oaicite:2]{index=2}.
• Thiabendazole: antifungal (yeast, dermatophytes) and acaricide—may help control ear mites :contentReference[oaicite:3]{index=3}.
• Dexamethasone: corticosteroid reduces redness, itching, and inflammation :contentReference[oaicite:4]{index=4}.

It's FDA-approved for treating bacterial, fungal, and inflammatory skin and ear infections in dogs and cats; also used off-label in ferrets :contentReference[oaicite:5]{index=5}.

2. Indications

• Acute or chronic otitis externa (ear infection) with bacterial/fungal components :contentReference[oaicite:6]{index=6}.
• Dermatitis (skin infections/inflammation) caused by bacteria or yeast :contentReference[oaicite:7]{index=7}.
• Ear mite infestations—thiabendazole helps prevent eggs from hatching :contentReference[oaicite:8]{index=8}.

3. Dosage & Administration

🐾 Otic Use (Ear)

Instill 5–15 drops into the ear canal twice daily. Clean the ear of debris first :contentReference[oaicite:9]{index=9}.

🐾 Topical Use (Skin)

Apply 2–4 drops per square inch of lesion twice daily, spreading gently over the area :contentReference[oaicite:10]{index=10}.

Do not exceed a one-week treatment duration unless directed by your vet—extended use may increase risks :contentReference[oaicite:11]{index=11}.

4. Onset & Duration

Topical relief often begins within 1–2 hours of application; noticeable signs improve after 1–2 days, with resolution typically by the end of the week :contentReference[oaicite:12]{index=12}.

5. Possible Side Effects

• Local irritation—redness, itching, swelling :contentReference[oaicite:13]{index=13}.
• Neomycin allergy—erythema at application site, rare :contentReference[oaicite:14]{index=14}.
• Transient discomfort—burning sensation for a few minutes, more in fissured areas :contentReference[oaicite:15]{index=15}.
• Systemic corticosteroid effects (rare with topical use) like increased thirst, urination if over‑used :contentReference[oaicite:16]{index=16}.
• Severe reactions—facial swelling, breathing difficulty: stop use immediately :contentReference[oaicite:17]{index=17}.

6. Contraindications & Precautions

• Do not use if eardrum perforation is suspected—inner ear damage risk :contentReference[oaicite:18]{index=18}.
• Avoid contact with eyes/mouth; rinse with water if accidental exposure occurs :contentReference[oaicite:19]{index=19}.
• Avoid use longer than a week—can suppress the immune system and promote resistant microbes :contentReference[oaicite:20]{index=20}.
• Keep refrigerated (36–46 °F/2–8 °C); discard if left unrefrigerated beyond one week :contentReference[oaicite:21]{index=21}.
• Contraindicated in pregnant animals; use only with vet advice :contentReference[oaicite:22]{index=22}.

7. Monitoring & Follow-Up

• Watch for resolution of symptoms—decreased itching, discharge, redness.
• Check for persistent signs: hearing loss, head tilt, continued irritation—may suggest worsened infection or eardrum issues :contentReference[oaicite:23]{index=23}.
• If no improvement within a week, return to your vet for re-evaluation.

8. Handling & Storage

• Store refrigerated, away from heat and light :contentReference[oaicite:24]{index=24}.
• Wear gloves during application and wash hands after use.
• Dispose of any unused solution after one week unrefrigerated or past expiry date.

9. Role of Ask A Vet, Woopf & Purrz

• Ask A Vet: Expert advice on dosage, conflicting medications, and when to call your vet.
• Woopf: Set reminders for twice‑daily dosing and track progress.
• Purrz: Log symptoms—discharge, itching, swelling—to monitor healing and aid vet decision‑making.

10. Pet Parent Insights

Owners often see ears and skin visibly improve in 3–5 days. One cat guardian shared: “After three days, the red, itchy spots were gone—ear canal looked much clearer!”

11. FAQs

🐾 Can I extend use beyond a week?

No—topical steroids can lead to systemic effects and resistance. Recheck with your vet for ongoing issues.

🐾 What if my pet shakes their head right after application?

Wait 5–10 minutes before allowing water or wiping to ensure medication stays in place.

🐾 What if ears smell faintly after treatment?

Some odor improvement is normal. Persisting or worsening odor may indicate failed treatment or deeper infection—contact your vet.

🐾 Can Tresaderm treat ear mites?

Yes—the antifungal component also inhibits mite eggs. However, adult mites may need additional treatment :contentReference[oaicite:25]{index=25}.
