Maropitant/PrednisoLONE Transdermal Pen (6mL)
Maropitant/PrednisoLONE is a compounded formulation containing Maropitant, PrednisoLONE, prepared by Mixlab for veterinary use. Available by prescription.
A transdermal pen is a simple way to give your pet medicine through their skin—usually used for cats by applying gel to the inside of their ear.
Step-by-Step:
- Get the pen ready – Twist the pen to dispense a small amount of gel. If it’s your first time, you will need to “prime” it first (the gel should be flush with the edge of the tip)
- Wear gloves – Always use a disposable glove or finger cot so the medication doesn’t absorb into your skin.
- Twist to dose – Follow the pen’s directions (like two full twists) to get the right amount of gel out. Always click in a clockwise direction, clicking counter-clockwise will stop you
- Pick the spot – Apply to a hairless area, usually the inside of your cat’s ear. Make sure the area is clean and dry.
- Apply the gel – Dab the gel directly with the pen or use your gloved finger to rub it in gently. Avoid the ear canal.
- Let it dry – It usually dries in a minute or two. Try to keep your pet from rubbing it off.
- Recap the pen – This keeps the medication fresh.
- Wash your hands – Even if you wore gloves, wash thoroughly after.
- Reward your pet – A treat helps make it a stress-free routine!
- Store properly – Keep at room temp, away from sunlight. Track doses so you know when it’s time to refill.
Important: Only apply where your vet has directed—usually hairless areas. Never apply over fur or broken skin. Keep other pets from licking the area until it’s dry.
This compounded formulation combines maropitant, an NK1-receptor antagonist antiemetic, with prednisolone, a corticosteroid — two different drug classes. In compounding practice, clinicians may consider a combination like this for a multi-targeted approach. Your veterinarian determines whether it is appropriate based on your animal's diagnostic findings.

At a pharmacological level, maropitant is considered for its role in managing the vomiting reflex while prednisolone is considered to influence the inflammatory response. Commonly observed effects include behavioral shifts such as increased thirst and urination (polyuria/polydipsia) and localized digestive changes like a temporary increase in appetite. Because the formulation contains a corticosteroid, your veterinarian will monitor for observational signs of steroid influence, especially with long-term use. Owners should monitor for significant behavioral changes and contact their veterinarian promptly with any concerns.

Veterinarians discuss this combination for pets whose inflammatory challenges may be accompanied by nausea or vomiting. This dual approach provides a method for addressing both the physical inflammation and the patient's gastrointestinal comfort.
Corticosteroids like prednisolone are typically tapered off gradually under professional guidance. Your veterinarian is the right person to provide a proper schedule to manage the risk of adrenal insufficiency.
Common observational signs include your pet seeking more water or needing more frequent outdoor breaks. If you notice unusual weakness or extreme behavioral shifts, contact your veterinarian for a clinical review.
