Fluoxetine<\/span><\/a> is a well-known <\/span>antidepressant<\/span><\/a> commonly used in cats to treat behavior issues such as anxiety, aggression, obsessive-compulsive behavior, and spraying. Veterinarians may also use fluoxetine to treat <\/span>itchy skin in cats<\/span><\/a> when other drugs don\u2019t help, but that use is less common. Better known by the brand name Prozac, fluoxetine belongs to a group of antidepressants called selective serotonin reuptake inhibitors (<\/span>SSRIs<\/span><\/a>). These drugs work by increasing the serotonin levels in the brain, which aids in decreasing anxiety and impulsiveness. Fluoxetine is the most commonly prescribed SSRI in cats. However, the use of fluoxetine in cats is <\/span>off-label<\/span><\/a>, and there are some concerns about its efficacy.\u00a0\u00a0<\/span><\/p>\n

What is fluoxetine used for in cats?<\/span><\/h2>\n

Veterinarians use fluoxetine in cats to treat behavior issues, including anxiety, spraying, and aggression. A <\/span>2016 survey<\/span><\/a> found that the most common reason veterinarians use fluoxetine in cats is for urinary marking and undesired elimination behaviors. Sometimes, a veterinarian may turn to fluoxetine to treat other conditions, such as itchy skin.\u00a0<\/span><\/p>\n

Anxiety<\/span><\/h3>\n

Cats <\/span>display anxiety<\/span><\/a> through unusual or impulsive behaviors like running away, hiding, or making noise. The most common type of anxiety in cats is separation anxiety.\u00a0<\/span><\/p>\n

Drugs are not always the first or best choice<\/span><\/a> for feline anxiety. Typically, veterinarians will ask pet owners to change the way they act toward the cat, modify the cat\u2019s environment, and work to train the cat with reinforcement training techniques. Antidepressants like fluoxetine can support this process when behaviors are particularly stubborn or extreme.<\/span><\/p>\n

Spraying (urine marking)\u00a0<\/span><\/h3>\n

Most cats that have not been neutered or spayed regularly <\/span>mark surfaces with urine<\/span><\/a>, including walls, drapes, sofas, and other objects. Even spayed and neutered cats do it, but it\u2019s less likely. Urine marking <\/span>is a common reason<\/span><\/a> people give up their cats to shelters. Like anxiety, urine spraying is best treated with behavior modification and environmental changes. Adding fluoxetine or another antidepressant to reduce a cat\u2019s anxiety can help behavioral and environmental treatments succeed.\u00a0<\/span><\/p>\n

Aggression<\/span><\/h3>\n

Aggression is <\/span>a common problem in dogs<\/span><\/a>, but cats sometimes behave aggressively toward other cats, people, or pets. According to a recent study, <\/span>27% of cats<\/span><\/a> brought to shelters for behavior problems are being given up for aggressive behaviors. Behavior modification and environmental changes are the first-line treatments. <\/span>There are many reasons for a cat\u2019s aggressive behavior<\/span><\/a>, so many possible interventions exist. Drugs like fluoxetine can help with some of the more hazardous or stubborn aggressive behaviors when other natural treatments don\u2019t solve the problem.<\/span><\/p>\n

Other veterinary conditions<\/span><\/h3>\n

Veterinarians can prescribe human drugs like fluoxetine when they believe they might help. Some veterinarians may use fluoxetine in a cat to treat obsessive-compulsive disorders, excessive grooming, itchy skin, bladder inflammation, and abnormal behaviors like hyperactivity or inappropriate urination.\u00a0<\/span><\/p>\n

Is fluoxetine safe for cats?<\/span><\/h2>\n

The use of fluoxetine in cats has not been well researched. Still, fluoxetine is widely used in cats for behavioral conditions, often in combination with other therapies, and its <\/span>adverse effects are typically mild or manageable<\/span><\/a>. However, some cats may have problems with fluoxetine because of pre-existing conditions:<\/span><\/p>\n
