Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that helps manage anxiety and behavior-related problems in dogs by increasing the serotonin levels in their brain — a chemical which regulates emotions, mood, and well-being. Vets often prescribe it to improve a dog’s overall mood and manage behaviors associated with stress. 

Common symptoms that fluoxetine treats include:

• Whining or barking excessively
• Pacing and restlessness 
• Frequent yawning
• Destructive behavior (chewing and scratching furniture)
• Panting when not overheated 
• Hiding or avoiding interaction
• Trying to escape in stressful situations

Conditions that fluoxetine treats include:

• Separation anxiety
• Obsessive-compulsive disorders (repetitive behaviors like tail-chasing, excessive licking, etc.) 
• Impulsive, fear-based aggression

Fluoxetine capsules or tablets are given orally to cats and dogs, following the dosage instructions from your veterinarian. Administering it with food can prevent stomach upset.

Fluoxetine is prescribed for cats and dogs experiencing anxiety, compulsive behavior, or aggression. Vets may recommend it for pets in need of long-term support for managing stress-related issues. For example, it may be suitable for a dog with separation anxiety or a cat that’s excessively grooming itself.

The active ingredient in this medication is fluoxetine hydrochloride. It’s a selective serotonin reuptake inhibitor, which increases the serotonin levels in the brain to improve mood and reduce anxiety.

Fluoxetine hydrochloride is the generic form of Prozac, a well-known medication used for the management of behavioral issues in pets.

The biggest adverse effects of fluoxetine are associated with gastrointestinal upset, including lack of appetite, vomiting, diarrhea, and/or weight loss. Other signs, although infrequent, include tremors, restlessness, and excessive vocalization. To minimize side effects, we prefer to start at a lower dose for the first few weeks.

Be sure to tell your vet about any medications, vitamins, or supplements that your pet is taking.

Fluoxetine helps manage anxiety and behavior-related issues in both cats and dogs, helping them feel calmer and happier. Your veterinarian will provide instructions about how to administer it to your dog, including the exact dosage, which depends on the pet’s weight, age, and condition. 

Watch your pet for any changes in appetite, behavior, or energy levels once they start fluoxetine. If you notice they’re behaving unusually, contact their vet right away.

You should always keep fluoxetine in its original container at room temperature, away from moisture, direct sunlight, and heat, and out of reach of children and pets to avoid accidental ingestion. Proper storage ensures the medication remains effective and keeps pets and children in your home safe.

Fluoxetine can interact with other medications, increasing the risk of side effects or reduced effectiveness. This is why you should avoid giving it alongside other antidepressants, some pain medications, and any other medication that affects the serotonin levels in any way, without prior vet consultation. 

Report any meds, supplements, or herbal remedies that your dog is taking to the vet. They may adjust the doses or recommend safer alternatives to reduce the risk of possible interactions.

If you miss a dose of fluoxetine, give it as soon as you remember. However, if it’s almost time for the next scheduled dose, skip the missed one and continue with the regular dosing schedule. 

Never give a double dose to make up for a forgotten dose. If you’re not sure what to do or if your dog is exhibiting unusual behavior after a missed dose, consult your vet right away.
