Compounded Fluoxetine (Prozac)

Fluoxetine is a medication used in animal and humans. In animals, it is often used to treat behavioral problems such as aggression, obsessive-compulsive disorder, and anxiety in dogs, cats, and birds. It has also been shown useful in treating cats that have inappropriate urination or spraying. It has been FDA approved to treat separation anxiety in dogs. This medication takes several doses before you see any effect. It often takes several weeks before you see the full effect of the medication. While it can be frustrating, it is important to dose the patients consistently during this refractory period. Sometimes it can take upwards of 3 weeks in order to see a change in behavior. Fluoxetine does require a prescription from your veterinarian/doctor in order to be dispensed. You and your doctor should discuss if this is the best treatment option.
