Antidepressants and Pets: An Increasingly Common Accidental Poisoning

As antidepressant medications have become more commonly prescribed, accidental pet ingestion has become one of the more frequent human-medication poisonings vets see. Different classes (SSRIs, SNRIs, tricyclics, and others) have somewhat different effects, but there's enough overlap in the general danger picture that any accidental ingestion is worth taking seriously regardless of the specific medication name.

Cats, interestingly, sometimes seek out certain antidepressants that have been reported to have a mildly attractive taste or smell to them, which is a less common but real access pathway beyond the usual dropped-pill scenario.

Symptoms to watch for: agitation, vocalization, dilated pupils, tremors, an elevated heart rate, and in more serious cases, seizures — a set of symptoms sometimes referred to as serotonin-related toxicity when severe. Some sedating types can instead cause lethargy and wobbliness rather than agitation, depending on the specific medication.

What to do right now: any known or suspected ingestion of any antidepressant medication should be assessed the same day at minimum, and treated as an emergency if any agitation, tremors, or significant behavior change appears.

When it's an emergency: any tremors, seizures, or significant agitation/vocalization following ingestion.
