FamOTIDINE Transdermal Pen (9mL)
FamOTIDINE is a compounded formulation containing FamOTIDINE, 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.

Famotidine is an H2-receptor antagonist utilized extensively in veterinary medicine for its ability to manage gastric acid production. It is a prescription and over-the-counter medication available for use in dogs and cats, requiring professional guidance from a licensed veterinarian. It is frequently considered in the context of digestive health for patients presented with localized stomach irritation or ulcers.
Prescription only. Use only under the direction of a licensed veterinarian. This information is not a substitute for veterinary diagnosis, prescribing or monitoring. Compounded drugs are not approved by the FDA for safety or effectiveness.
Commonly observed effects include temporary digestive shifts such as a decrease in appetite or behavioral shifts like lethargy. Because famotidine blocks histamine receptors on the parietal cells of the stomach, it provides a method for managing the volume and acidity of gastric secretions. Your veterinarian will monitor for observational signs of sensitivity, particularly in pets with pre-existing renal or hepatic impairment. Owners should monitor their pet for any unusual behavioral changes and contact their veterinarian promptly with concerns.
While famotidine is available over-the-counter, Mixlab dispenses it upon receipt of a valid authorization from a licensed veterinarian to ensure the dose and management approach are appropriate for your pet.
Yes. Mixlab specializes in compounding famotidine into customized strengths and flavored oral formats, such as flavored oral liquids or treats, to support easier administration for your pet.
Veterinarians discuss famotidine because it manages the amount of acid produced by the stomach. This provides a method for managing localized irritation and supporting the recovery of the stomach lining.
Some human formulations contain additional ingredients that may not be suitable for pets. You should only use medications that have been specifically reviewed and authorized by your veterinarian for your pet's safety.
Your veterinarian will provide guidance on the necessary duration of use. They may recommend periodic check-ups to ensure the management approach remains suitable for your pet's digestive challenges.
