Zoloft For Anxiety: Effectiveness, Dosage, & More

What Is Zoloft (Sertraline)?

Zoloft (sertraline) is a medication that is used to treat depression and anxiety disorders. It is a selective serotonin reuptake inhibitor (SSRI) that works by inhibiting the reuptake of serotonin.¹ By increasing the amount of serotonin in the brain, Zoloft can help to improve mood and reduce anxiety symptoms.

Zoloft is typically used to treat adults with depression, anxiety disorders, and other mental health conditions. Zoloft may also be used for children over the age of six and adolescents with certain conditions, although its safety and effectiveness in these cases has not been established.² Zoloft has not been specifically studied in seniors, but it may be used in this population with caution.

Zoloft is generally considered to be safe for use during pregnancy, although it may cause side effects in some people.² It is important to talk to a healthcare provider about the potential risks and benefits of taking Zoloft during pregnancy, and to follow the recommended dosing and treatment plan.

Why Is Zoloft Used to Treat Anxiety Disorders?

While Zoloft does not cure anxiety, it can help to improve mood and reduce anxiety symptoms, making it easier for individuals to manage and carry out their daily activities. Zoloft is typically used as part of a comprehensive treatment plan for anxiety disorders, which may also include therapy, lifestyle changes, and other medications.

Zoloft may be especially helpful for certain types of anxiety disorders, such as panic disorder, generalized anxiety disorder, and social anxiety disorder. It may also be useful in preventing panic attacks and in the treatment of specific phobias. Zoloft is an on-label medication for anxiety, meaning that it has been specifically approved by the FDA for the treatment of anxiety disorders.

Some individuals may turn to Zoloft over other anxiety medications because it is generally considered to be safe and effective. Other anti-anxiety medications (benzodiazepines) work by reducing symptoms short-term, but do not work long-term. These medications also carry significant risk of addiction and are controlled by DEA.³

The exact mechanisms by which SSRIs help reduce anxiety symptoms are not fully understood, but it is thought that the increased availability of serotonin may help improve mood, reduce feelings of worry and stress, and improve overall well-being. SSRIs may also help improve sleep and reduce physical symptoms of anxiety, such as racing heart, rapid breathing, and trembling.

How to Take Zoloft for Anxiety

Zoloft is available in a number of forms, including tablets, capsules, and oral suspension (liquid). It is commonly prescribed in the tablet or capsule form and is taken once a day, either in the morning or evening. It is important to take Zoloft at the same time every day to maintain a consistent level of the medication in your body. The extended-release form of Zoloft, called Zoloft sustained-release (SR), is designed to be taken once a day, either in the morning or evening, and should not be crushed or chewed.

How Long Does it Take for Zoloft to Work For Anxiety?

It may take several weeks for Zoloft to start working. However, exactly how long it takes for Zoloft to work can vary depending on a number of factors, including the severity of your anxiety, your individual response to the medication, and any other treatment you may be receiving.

Zoloft Dosage For Anxiety

The effective dosage of Zoloft for treating anxiety symptoms varies based on a number of factors including age, the nature of the anxiety disorder, and the patient’s response to the medication. Doctors may start patients on a lower dosage and gradually increase it as needed to find the most effective dose. Similarly, doctors may start at different dosages depending on the mental health disorder that they are treating. For example, patients with obsessive compulsive disorder (OCD) are typically started at a higher dose.⁴ It is important to follow your doctor’s instructions and to report any side effects or concerns you may have about your medication.

Can You Overdose on Zoloft?

If you believe you have taken too much Zoloft or have overdosed on the medication, it is important to seek medical attention immediately. You can call 9-1-1 or your local emergency number for help. Symptoms of an overdose on Zoloft may include dizziness, drowsiness, tremors, agitation, sweating, vomiting, diarrhea, and rapid heartbeat. In severe cases, an overdose on Zoloft may cause seizures or coma.

While it is possible to overdose on Zoloft, it is not common and the risk of overdose is generally low when the medication is taken as directed by a doctor. However, taking Zoloft in combination with other medications or substances that affect serotonin levels (such as other antidepressants or recreational drugs) may increase the risk of serotonin syndrome, a potentially life-threatening condition characterized by high levels of serotonin in the body.

Side Effects of Zoloft While Treating Anxiety

Side effects of Zoloft that may be more noticeable when treating anxiety disorders include dizziness, drowsiness, and difficulty sleeping. These may become more prevalent when starting treatment with Zoloft or when the dosage is increased, but they usually go away after the body adjusts to the medication. If these side effects persist or are severe, it is important to speak with your doctor about adjusting your dosage or trying a different medication.
