It works as a serotonin 5-HT3 receptor antagonist and is commonly prescribed for pets experiencing vomiting due to chemotherapy, gastrointestinal upset, or post-operative recovery.
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.
