Prevents mast cells from degranulating — stopping the release of histamine, leukotrienes, and other inflammatory mediators before they trigger symptoms.
Blocks histamine H1 receptors directly at target tissues — a second line of action that manages symptoms even when some mediator release occurs.
Compounded fluoxetine chewable treats make daily behavioral medication practical for dogs — flavored in chicken or beef, with doses tailored to each dog's weight for anxiety, OCD, and aggression management.

Fluoxetine selectively inhibits serotonin reuptake, increasing serotonin availability in the synapse and reducing anxiety-driven behaviors.
Compounded flavored chewable formulations dramatically improve compliance versus commercial capsules, and allow dose adjustments not available in standard commercial strengths.
Fluoxetine is the most widely prescribed behavioral medication in dogs and is indicated for canine separation anxiety, generalized anxiety, obsessive-compulsive behaviors (tail chasing, lick granulomas, flank sucking), and aggression. The FDA-approved veterinary product is Reconcile (flavored chewable), but it is only available in 8mg, 16mg, 32mg, and 64mg sizes — limiting dose flexibility for very small dogs or those needing intermediate doses.
Compounded fluoxetine chewable treats allow precise weight-based dosing in any strength, with custom flavoring (chicken, beef, peanut butter) that makes daily administration feel like a treat rather than a medication, dramatically improving long-term compliance.
Fluoxetine is a selective serotonin reuptake inhibitor (SSRI). It blocks the serotonin transporter (SERT) protein on presynaptic neurons, preventing the reuptake of serotonin from the synapse. This increases the concentration of serotonin available to bind postsynaptic receptors, producing anxiolytic and mood-stabilizing effects over time.
The therapeutic effect of SSRIs typically takes 4–8 weeks to fully manifest, as receptor downregulation and neuroadaptation are required for full behavioral effects.
Compounded fluoxetine chewables are used in dogs for separation anxiety, generalized anxiety disorder, obsessive-compulsive disorder (excessive licking, tail chasing, pacing), fear-based aggression, and storm/noise phobias when used as part of a comprehensive behavior modification program.

⚠️ Dosing should be determined by your prescriber. The information below is general guidance only.
Common side effects include decreased appetite (usually transient), mild sedation, and GI upset during the first 1–2 weeks of therapy. Some dogs experience slight behavior changes early in treatment as serotonin levels adjust.
Serotonin syndrome (tremors, hyperthermia, agitation) is a rare but serious risk if fluoxetine is combined with other serotonergic medications such as tramadol or trazodone. Consult your veterinarian before combining with other drugs.
