However, the FDA has also approved it for the treatment of social anxiety disorder, a mental health condition marked by an irrational fear of being watched or judged, or of embarrassing or humiliating oneself. Zoloft for Anxiety Zoloft is a selective serotonin reuptake inhibitor (SSRI), which works to slow the reabsorption of the neurotransmitter serotonin, a chemical that helps regulate mood and control anxiety. Clinicians also use it to treat other mental health conditions, including major depressive, obsessive-compulsive, premenstrual dysphoric, panic, and post-traumatic stress disorders. Illustration by Alexandra Gordon, Verywell Precautions When Taking Zoloft for Anxiety Use Zoloft with caution if you: Are allergic to sertraline, the active ingredient in ZoloftAre being treated with medication for alcohol abuseAre breastfeedingAre pregnant (especially in the third trimester) or planning to become pregnantHave bipolar disorder or a family history of bipolar disorderHave impaired liver or kidney function, heart disease, diabetes, or a history of seizures The FDA has not approved Zoloft for the treatment of social anxiety disorder in people under 18 years of age. Evidence suggests an increased risk of suicidal thoughts and behaviors in children taking Zoloft. If you or your child are having suicidal thoughts, contact the National Suicide Prevention Lifeline at 988 for support and assistance from a trained counselor. If you or a loved one are in immediate danger, call 911. For more mental health resources, see our National Helpline Database. How Does Zoloft Make You Feel? Zoloft Dosage for Anxiety Zoloft is available in 25, 50, and 100 mg tablets and a 20 mg/ml oral solution. Check your prescription and consult your doctor to make sure you're taking the correct dose. For people with social anxiety disorder, a typical dosage of Zoloft starts at 25 mg, with an increase to 50 mg after one week. Weekly increases up to a maximum dose of 200 mg are permitted for patients who do not respond to lower doses. Modifications Certain populations may require an adjusted dosage and/or close monitoring by their healthcare provider. Children 6 to 17 years old may require closer monitoring and a subsequent dosage change if they experience significant weight loss and/or suicidal ideation during the first few months of taking Zoloft.People who are pregnant or nursing must discuss the risk and benefits of taking Zoloft, because it can pose a risk to the fetus during the third trimester and to the newborn while breastfeeding.Older patients begin with lower dosages so prescribers can monitor them for adverse reactions before increasing dosages if needed. How to Take and Store Generally, expect to take Zoloft once daily, with or without food, within the following guidelines. Swallow the tablets whole, not chewed or crushed. If you're taking the liquid form, combine the prescribed amount of medication with one-half cup of liquid (water, ginger ale, lemon-lime soda, lemonade, or orange juice). Prepare each dose immediately before you take it, not in advance. If you forget to take a daily dose, take it as soon as you remember. However, if it is close to the time of your next dose, skip the missed dose and take it at your regular time. Never take two doses of Zoloft at the same time. When traveling, store Zoloft in your carry-on baggage in case your luggage gets lost. It's important to continue taking Zoloft as long as your doctor instructs, even if you begin to feel better.
