Zoloft (sertraline) is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs). Sertraline affects chemicals in the brain that may become unbalanced and cause depression, panic, anxiety, or obsessive-compulsive symptoms.
Zoloft is used to treat depression, obsessive-compulsive disorder, panic disorder, anxiety disorders, post-traumatic stress disorder (PTSD), and premenstrual dysphoric disorder (PMDD).
Zoloft may also be used for purposes not listed in this medication guide.
Important information
You should not use Zoloft if you also take pimozide, or if you are being treated with methylene blue injection.
Do not use Zoloft if you have taken an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, and tranylcypromine.
Some young people have thoughts about suicide when first taking an antidepressant. Your doctor will need to check your progress at regular visits while you are using Zoloft. Your family or other caregivers should also be alert to changes in your mood or symptoms.
Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.
Do not give Zoloft to anyone younger than 18 years old without the advice of a doctor. Zoloft is FDA-approved for children with obsessive-compulsive disorder (OCD). It is not approved for treating depression in children.
