FamOTIDINE/Ondansetron is a compounded formulation containing FamOTIDINE, Ondansetron, prepared by Mixlab for veterinary use. Available by prescription.

Chew treats are flavored, soft treats that contain your pet’s medication—making giving meds as easy as offering a snack!

Use as directed by your veterinarian.

This compounded formulation combines famotidine, an H2-receptor antagonist, with ondansetron, a 5-HT3-receptor antagonist antiemetic — two different drug classes. In compounding practice, clinicians may consider a combination like this for a multi-targeted approach. Your veterinarian determines whether it is appropriate based on your animal's diagnostic findings.

At a pharmacological level, famotidine manages gastric acid while ondansetron manages the vomiting reflex by blocking serotonin receptors in the peripheral and central nervous systems. Commonly observed effects include temporary digestive shifts such as constipation or behavioral shifts like lethargy. Because it influences serotonin pathways, your veterinarian will monitor for observational signs of sensitivity if used with other serotonergic medications. Owners should monitor for significant behavioral changes and contact their veterinarian promptly with concerns regarding the patient's response.

Do I need a prescription for this combination?

Yes. This combination of famotidine and ondansetron is a prescription medication and requires a valid authorization from a licensed veterinarian. Mixlab verifies all legal requirements before preparing any medication.

Can this combination be compounded for my pet?

Yes. Mixlab specializes in compounding famotidine and ondansetron into customized strengths and flavored oral formats, such as flavored liquids or treats, to support easier administration. The decision rests with your prescribing veterinarian.

Why are these two medications combined?

Veterinarians discuss this combination for pets presented with excess stomach acid and persistent nausea. This dual approach provides a method for managing digestive comfort during the recovery from various illnesses.

How long can my pet take this?

Your veterinarian will determine the appropriate duration of the management approach. They will provide a professional schedule to ensure the protocol remains suitable for your pet's digestive recovery.

Will this medication cause constipation?

Mild constipation is a commonly observed effect of ondansetron in some pets. Your veterinarian will provide guidance on monitoring your pet's stool consistency during the course of management.
