Serotonin Syndrome In Dogs: Symptoms, Causes, & Treatments

2021-11-23  PetsCareTip

Serotonin syndrome in dogs is a potentially life-threatening condition caused by an increase of serotonin in the body from exposure to antidepressant medication. Serotonin is an important neurotransmitter in a dog’s brain that regulates heart and lung function, behavior, awareness of pain, appetite, body temperature, and movement.

When used appropriately, antidepressants elevate the levels of serotonin in the brain. However, there are several situations where an antidepressant might be mixed with other medications, react with certain foods, or be poorly tolerated by a dog and lead to serotonin syndrome.

This can cause illness, altered mental states, and even death if it goes untreated. If your dog is showing signs of serotonin syndrome after taking an antidepressant, then consult your veterinarian right away.

Furthermore, symptoms tend to come on quickly - within ten minutes to four hours of taking the drug.

Here’s what you should know about the symptoms, causes, and treatments for serotonin syndrome in dogs.

Symptoms Of Serotonin Syndrome In Dogs

Serotonin syndrome in dogs can cause symptoms throughout the body because serotonin is so important for regulating many of the body’s functions. It can affect the cardiovascular system, the nervous system, the gastrointestinal tract, metabolism, and the respiratory system. Treatment must begin quickly, or the condition may be fatal.

If you see the following symptoms in your dog after they’ve been exposed to an antidepressant, contact your vet immediately:

  • Vomiting
  • Diarrhea
  • High blood pressure
  • Trembling
  • Seizures
  • Difficulty walking
  • Rigid muscles
  • Confusion, depression, hyperactivity
  • Rapid breathing
  • Increased body temperature
  • Lethargy
  • Tachycardia (rapid heart rate)
  • Agitation or aggression
  • Behavioral abnormalities
  • Temporary blindness
  • Coma

Causes Of Serotonin Syndrome In Dogs

Exposure to antidepressant drugs causes serotonin syndrome in some dogs. Some of the most common antidepressants prescribed to dogs are busiprone, fluoxetine, and clomipramine.

When used correctly, these medications usually work properly. However, there are some circumstances where the drugs create an excess of serotonin, and serotonin syndrome is the result.

Here are some reasons these drugs might result in serotonin syndrome:

  • High sensitivity to drugs that affect serotonin
  • Dosage is too high
  • Mixing other drugs that affect serotonin, such as amphetamines, fentanyl, or lithium
  • Certain foods interact with the medication, such as for example cheese, turkey, red meat, bananas, peanut butter, or anything containing L-tryptophan

Treatments For Serotonin Syndrome In Dogs

Treatment for serotonin syndrome in dogs needs to begin quickly, or the problem may be fatal. If the condition is caught within a half hour, then activated charcoal can end up being ingested to reduce the amount of antidepressant that the dog’s system will absorb.

If the drug is still in the stomach, inducing vomiting or stomach pumping may be an option. Sometimes a vet may provide oxygen therapy or intubation. They may also prescribe medication to control seizures or tremors and give the dog a serotonin antagonist.

Additionally, affected dogs should not continue to use the drug that caused the serotonin syndrome, and they should stop consuming any foods or other drugs that affect serotonin. Once the dog recovers, the vet will determine if prohibited foods can be reintroduced to the diet.

Prevention goes a long way. Follow all instructions from your veterinarian when giving your dog antidepressants, and make sure they are aware of any other medications, even over-the-counter drugs, that your dog is taking.
