How to Give Anhydrous Oral Suspension
Oral Suspension (Anhydrous) is a liquid medication that does not contain water in its base. This might be an oil-based or other special base to help stabilize the medicine. It will look like a regular liquid medication, but often needs a good shake because the drug can settle. Here's how to give it:
- Shake well each time to mix the medication (5-10 seconds).
- Measure the dose using the syringe/dropper provided or one recommended by your vet. Insert the top of the oral syringe into the bottle adapter. Turn the bottle upside down and pull the plunger until the medicine reaches the volume required
- Hold your pet steady: a towel or helper can assist with squirmy pets.
- Administer the dose slowly into the side of the mouth. Allow small pauses if needed for swallowing.
- Raise the head slightly to help the medication go down and clean any spills with a little water or tissue.
- Praise your pet and offer a treat or water (unless advised against feeding right after).
- Clean the syringe with water immediately after use. Store the bottle as directed, out of sunlight.
- Consistency is key: Shake each time, measure accurately, and contact your vet if any issues arise.

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.
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.
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.
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.
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.
