Sertraline and Pets

Sertraline, commonly known by the brand name Zoloft, is a selective serotonin reuptake inhibitor (SSRI) used in humans to treat depression, anxiety, and related disorders. While it can be prescribed by veterinarians in very specific circumstances, accidental ingestion or overdose in dogs and cats is dangerous and can lead to serotonin syndrome, a potentially life-threatening condition. Pets are far more sensitive to these medications than humans, and even a small number of pills can cause serious toxicity.

Exposure usually happens when a pet chews through a medication bottle, finds a dropped pill on the floor, or is accidentally given a human dose. Dogs may be attracted to the smell or taste of coated tablets, while cats may ingest fragments left on countertops or bedding. Because sertraline is absorbed quickly, symptoms can appear within hours and may worsen rapidly without treatment.

If you suspect your dog or cat has eaten sertraline, seek veterinary help immediately. Do not wait for symptoms to appear, and do not try to induce vomiting unless a veterinarian or poison control professional specifically tells you to do so. Bring the medication packaging with you so your vet can determine the exact dose and formulation your pet may have consumed.

Prevention is the safest approach. Store all human medications, including antidepressants, in a secure cabinet or container that your pet cannot access. Take pills over a sink or closed area, and check the floor afterward for dropped tablets. Never give your pet any medication intended for humans without direct veterinary guidance.
