Oxazepam
Also known as: Serax
> **Important:** Oxazepam is a prescription medication used to stimulate appetite or reduce anxiety. It is a controlled substance. * **Timing for Appetite:** If using this medication to help your pet eat, give it approximately **30 minutes before feeding** for the best results. * **Do Not Stop Abruptly:** If your pet has been taking this for behavior issues, do not stop the medication or change the dose without consulting your veterinarian. Sudden withdrawal can cause a "rebound" effect, making anxiety or bad behaviors worse. * **Watch for Clumsiness:** The most common side effects are sleepiness and mild wobbliness (ataxia). Keep your pet away from stairs or high places until you know how the medication affects them. * **Unexpected Reactions:** Rarely, some pets may have a "paradoxical" reaction where they become hyperactive, vocal, or aggressive instead of calming down. Contact your vet immediately if this happens.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

- **Important Warnings & Precautions:** * **Hepatic Dysfunction:** Use with caution. While less susceptible to accumulation than other benzodiazepines, rare anecdotal reports link oxazepam to fulminant hepatic failure in cats. * **Myasthenia Gravis:** Benzodiazepines may exacerbate muscle weakness. * **Seizure Disorders:** Use with caution in susceptible patients; rarely, it has precipitated tonic-clonic seizures. * **Pregnancy & Nursing:** FDA Category D (teratogenic effects noted in animal models). Excreted in maternal milk; neonates metabolize the drug slowly, leading to potential toxic accumulation. Avoid in nursing mothers. * **Withdrawal:** Avoid abrupt discontinuation to prevent rebound behavioral effects.
