What is Fluox?

Fluoxetine is the main active ingredient found in Fluox which is a medication used to treat behavioural issues in cats and dogs. It is a selective serotonin reuptake inhibitor (SSRI), working to increase the amount of serotonin, a neurotransmitter, in the brain. This can help regulate mood and behaviour, especially in cases of stress and anxiety in pets. Fluoxetine has been used in pet behaviour issues such as inappropriate urine marking, separation anxiety, obsessive chewing, circling, and self-mutilation, even aggression. It is vital to also treat behavioural problems with training and changes to the pets’ environment in addition to medication.

How does it work?

Fluox helps to prevent serotonin from being reabsorbed into the nervous system, resulting in an increased serotonin level between nerve cells. This can help in regulating mood and behaviour in pets, particularly useful in managing conditions like separation anxiety, inappropriate urination in cats, and certain obsessive-compulsive behaviours.

Dose and Administration

Your veterinarian will determine the correct dosage for your pet based on their specific needs. It's crucial to follow your vet's instructions closely. Generally, Fluox is administered orally, once or twice daily, and it may take up to 4-8 weeks for the full effect to be observed. If discontinuation the medication, gradually reduce the dose over 3-5 weeks, or as advised by your vet. Usually it is advised to give the medication with food.

Overdose:

In cases of a suspected overdose, immediate veterinary care is crucial. Overdose symptoms can include seizures, lethargy, agitation, incoordination, and excess drooling. For any concerns or emergencies related to Fluox ingestion in pets, contact the New Zealand National Poisons Centre (http://www.poisons.co.nz/animal-helpline/ or phone 0800 869 738).

Contraindications and Precautions

Fluox should be avoided in pets with diabetes or epilepsy. Fluox can interact with other medications so alway inform your vet of other medications or supplements your pet is being given.

Potential Side Effects

Some pets may experience the following side effects:

  • Vomiting and diarrhoea

Serotonin syndrome is uncommon but a potentially dangerous situation that happens when serotonin levels get too high. Signs include increased heart rate, shivering, dilated pupils, rapid breathing, and hyperactivity.

If you notice any of these symptoms, it is essential to consult your veterinarian.

Storage

Fluox should be stored at controlled room temperatures. Ensure the medication is kept in a light-resistant container and out of reach of children and pets.

Monitoring

Regular monitoring by your veterinarian is recommended to assess the effectiveness of the treatment. For behavioural problems, it is also important to implement training as part of a treatment plan.
