Buspirone HCL is a compounded formulation containing Buspirone HCL, 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:

  1. 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)
  2. Wear gloves – Always use a disposable glove or finger cot so the medication doesn’t absorb into your skin.
  3. 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
  4. Pick the spot – Apply to a hairless area, usually the inside of your cat’s ear. Make sure the area is clean and dry.
  5. Apply the gel – Dab the gel directly with the pen or use your gloved finger to rub it in gently. Avoid the ear canal.
  6. Let it dry – It usually dries in a minute or two. Try to keep your pet from rubbing it off.
  7. Recap the pen – This keeps the medication fresh.
  8. Wash your hands – Even if you wore gloves, wash thoroughly after.
  9. Reward your pet – A treat helps make it a stress-free routine!
  10. 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.

Buspirone utilizes an azapirone strategy to manage chronic anxiety. It is a prescription-authorized medication frequently considered for cats and dogs presented with behavioral challenges.

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 following the administration of buspirone hydrochloride include increased affection or "clinginess" in some cats, while others may exhibit localized digestive changes such as a decrease in appetite or vomiting. Some dogs may show behavioral shifts including increased agitation or restlessness. A notable and observation in multi-cat environments is that previously timid cats may become more assertive, which your veterinarian will consider when evaluating the household dynamic. Owners should watch for any sudden behavioral shifts or physical changes and contact their veterinarian promptly with any concerns.

This medication is typically used with extra caution or avoided in patients with known severe hepatic or renal impairment, as these organs are responsible for the metabolism and excretion of the prescription. Significant interactions can occur if buspirone is used concurrently with monoamine oxidase inhibitors (MAOIs) or other medications that influence serotonin levels, which could lead to a serious clinical event known as serotonin syndrome. Before starting a protocol, ensure your veterinarian has a complete history of all other medications and supplements your pet is receiving. Your veterinarian is the right person to provide guidance on the necessary duration of use and the most commonly considered monitoring schedule to ensure the management approach remains suitable for your pet's individual needs.

Do I need a prescription to get buspirone for my pet?

Yes. Buspirone hydrochloride is a prescription medication and can only be dispensed by a licensed pharmacy upon receipt of a valid authorization from a licensed veterinarian. Mixlab verifies all veterinarian-client-patient relationships before any medication is prepared or shipped to your home.

Can buspirone be compounded for my pet?

Yes. While buspirone is available in commercial human-strength tablets, Mixlab specializes in compounding the active ingredient into customized strengths and flavored dosage forms—such as flavored oral liquids, chewable may be considered in cases of or small capsules—to suit the specific needs of dogs and cats. The decision between a commercial and compounded product rests with the prescribing veterinarian.

How is buspirone different from Xanax for pets?

Veterinarians often discuss buspirone as a daily management tool for anxiety because it does not cause the sedation or muscle relaxation typically seen with medications like Xanax (alprazolam). Additionally, while alprazolam is used for situational events like thunderstorms, buspirone is generally utilized as a long-term approach to stabilize a pet's baseline anxiety levels.

How long does it take for buspirone to start working in pets?

Unlike some medications with a more immediate onset, buspirone typically requires consistent daily administration for several weeks before its full physiological influence is observed. Your veterinarian will discuss the expected onset timing and may recommend a management approach that includes environmental modifications while the medication builds up in your pet's system.
