Someone who’s taken too much Zoloft could have one or many symptoms ranging from mild to severe, but they’re rarely life-threatening. Some are common in most cases, whereas other, less common effects can be more consequential.

It’s also used to treatmajor depressive disorderandpremenstrual dysphoric disorder(PMDD).

Signs of an Antidepressant Overdose
Among the most serious risks of Zoloft overdose isserotonin syndrome, in which levels of serotonin reach a level that can cause symptoms such as:
Serotonin syndrome is most likely to happen in interaction with another drug.
How Much Zoloft Is Too Much?A person’s tolerance for a drug depends on many factors, such as age, body weight, overall health, and other substances ingested. For this reason, it’s difficult to know whether a particular dose of Zoloft might be harmful for a particular person. One dose may be exactly right for relieving symptoms for one person, whereas the same amount of medication could cause symptoms of overdose in another.

Getting Help for Zoloft Overdose
If you or someone you know has accidentally taken a higher dose of Zoloft than prescribed, it’s a good idea to get help right away, before the drug has a chance to cause unpleasant or dangerous symptoms.
If a trip to an emergency room isn’t possible, call the national toll-free Poison Control hotline at 1-800-222-1222 or visitPoisonHelp.org. The staff there is trained to assess your situation over the phone and give advice about what to do.
Information to Have Ready
When you go to the emergency room or call Poison Control, the more information you can provide, the more precise the treatment can be. Having the following information available will be helpful:
Treatment for Zoloft Overdose
If the overdose was fairly recent, healthcare providers might pump the person’s stomach to remove any of the drug that the body has not absorbed yet. Another option is to use activated charcoal to absorb any remaining medication in the stomach.
There’s no antidote for a Zoloft overdose. Healthcare providers will monitor the person’s vital signs—heart rate, breathing, and blood pressure—and treat any problems that might arise.
SSRIs like Zoloft rarely cause death, even with an overdose; most deaths occur because of co-ingestion with other drugs.
The next step is to make sure that an overdose does not happen again. To prevent accidental overdose:
If the overdose was intentional, short-term treatment might involve hospitalization until therisk of suicideis no longer imminent. Health professionals might advise switching to another type of antidepressant if sertraline has not been effective in reducing depressive symptoms.
Long-term treatments might involve further use of antidepressants,psychotherapy, andpsychosocial supportto address suicidal thoughts andsymptoms of depression.
