The Vet’s 2025 Guide to Selegiline 🧠🐶: Uses, Dosage & Pet Care by Dr Duncan Houston BVSc

👋 Hello, pet parents! I’m Dr. Duncan Houston BVSc, here to walk you through one of the most important medications helping our senior pets thrive in 2025: Selegiline (aka Anipryl®) 💊🐕‍🦺.

🔍 What is Selegiline?

Selegiline hydrochloride is a powerful 💡 MAOI (monoamine oxidase inhibitor) that’s FDA-approved for treating Canine Cognitive Dysfunction Syndrome (CCD), often called "doggy dementia." 🧠🐶

It’s also used off-label for pets with Cushing’s disease and for feline cognitive issues 🐱💭.

📋 What Does Selegiline Treat?

• 🧠 Canine Cognitive Dysfunction (similar to Alzheimer’s in humans)
• 🕰️ Pituitary-dependent Cushing’s disease (in some cases)
• 🐱 Off-label for feline cognitive dysfunction

🐶 Signs Your Dog Might Need Selegiline:

• Confusion or disorientation 😕
• Disrupted sleep 💤
• Indoor accidents 🚽
• Less interest in family life or play 😢

🧪 How It Works

Selegiline helps preserve brain chemicals like dopamine and serotonin, which are vital for memory, mood, and behavior 🧬✨. It reduces oxidative stress and enhances mental clarity 🧠💥.

💉 Selegiline Dosage Guidelines

Always follow your vet’s instructions—but here’s a general guide:

• 🐶 Dogs with CCD: 0.5–1.0 mg/kg once daily, preferably in the morning ☀️
• 🐕 Cushing’s Disease: 1.0 mg/kg per day (max 6 weeks without improvement)
• 🐱 Cats (off-label): 0.25–1.0 mg/kg, often at night 🌙

💊 How to Give It

• Give with or without food 🥩
• Morning dosing helps avoid restlessness at night 🌄
• Try wrapping the tablet in soft treats or Purrz Pill Pockets 😋

⏱️ When to Expect Results

You may notice a brighter, more alert pet within 3 to 7 days 🎉. Full cognitive benefits often take 4 to 6 weeks.

⚠️ Selegiline Side Effects

While many pets tolerate Selegiline well, be alert for:

• 🤢 Nausea or vomiting
• 😴 Lethargy
• 😠 Agitation or restlessness
• 🚫 Appetite loss
• 😳 Rare: aggression, tremors, or serotonin syndrome (if mixed with other drugs)

Always tell your vet if your pet is on any of these:

• 💊 SSRIs (like fluoxetine)
• 💊 Tramadol, MAOIs, or tricyclics
• 🍖 Tyramine-rich foods (aged cheese, cured meats)

🔄 Drug Interactions

❗ Combining Selegiline with certain drugs can be dangerous. Avoid:

• Opioids (e.g., tramadol)
• Antidepressants (e.g., fluoxetine, clomipramine)
• Other MAOIs or herbal supplements without vet approval

Wait at least 14 days when switching between these drug types 🕑💊.
