What Zoloft is used for
Sertraline (brand name Zoloft) is a prescription SSRI that increases serotonin levels in the brain. In the United States, the FDA has approved it for several conditions. Doctors may also use it off-label for other disorders when appropriate.
FDA-approved indications:
- Obsessive-compulsive disorder (OCD) in adults and pediatric patients
- Major depressive disorder (MDD)
- Panic disorder
- Social anxiety disorder
- Post-traumatic stress disorder (PTSD)
- Premenstrual dysphoric disorder (PMDD)
Common off-label uses: generalized anxiety disorder, body dysmorphic disorder, and others at a clinician's discretion.
Some people begin to notice benefits in 1 to 2 weeks, but full effect can take 4 to 6 weeks or longer. If you are evaluating side effects or response, see Precautions and Side effects.
How to take Zoloft
Take sertraline once daily, at the same time each day, with or without food. Swallow tablets with water. If you use the oral concentrate, dilute it only as directed by the manufacturer before taking.
- Do not change your dose or stop suddenly unless your prescriber tells you to; a gradual taper is usually needed.
- Typical starting doses vary by condition and patient factors; your clinician will individualize the plan.
- If stomach upset occurs, taking with food may help.
- It can be taken in the morning or evening based on side effects such as drowsiness or insomnia.
Questions about other medicines you take at the same time should be checked against the Drug interactions section.
Key precautions
Before starting sertraline, tell your clinician about all health conditions, medicines, and allergies. Special care may be needed in the situations below.
- Suicidality warning: antidepressants can increase suicidal thoughts and behavior in children, adolescents, and young adults. Monitor closely, especially early in treatment or after dose changes.
- Mania or hypomania: use caution if you have bipolar disorder or a history of manic episodes.
- Bleeding risk: SSRIs may increase bleeding, especially with NSAIDs, aspirin, or anticoagulants.
- Low sodium (SIADH): older adults and those on diuretics are at higher risk.
- Glaucoma: may precipitate angle-closure in susceptible individuals.
- Seizure disorders: use carefully if you have a history of seizures.
- Liver impairment: dose adjustments may be required; liver disease can increase drug levels.
- Pregnancy and breastfeeding: use only if benefits outweigh risks. Late-pregnancy exposure may be associated with neonatal adaptation symptoms. Sertraline is often considered compatible with breastfeeding; discuss with your clinician.
Do not use sertraline if
- You are taking, or have recently taken, an MAO inhibitor such as phenelzine, tranylcypromine, isocarboxazid, selegiline, or linezolid, or you received IV methylene blue. Allow at least 14 days between sertraline and an MAOI in either direction.
- You take pimozide.
- You have had a serious allergic reaction to sertraline or any tablet components.
- You use disulfiram and plan to take the sertraline oral concentrate, which contains alcohol.
Possible side effects
Most side effects are mild and often improve with time. Contact your prescriber if symptoms are severe, persistent, or worrisome.
- Common: nausea, diarrhea, dry mouth, sweating, dizziness, fatigue, tremor, sexual dysfunction, insomnia or drowsiness, headache, decreased appetite.
- Less common but important: rash, easy bruising or bleeding, agitation, restlessness, hyponatremia symptoms such as confusion or weakness.
- Seek urgent care for: serotonin syndrome symptoms such as high fever, confusion, muscle rigidity, shivering, rapid heart rate; severe allergic reaction; fainting; seizures; eye pain with vision changes suggesting angle-closure glaucoma.
If you experience something not listed here, inform your healthcare professional. For full risk information, see the FDA Medication Guide and speak with your pharmacist.
Drug and supplement interactions
Always give your prescriber and pharmacist a complete list of medicines, vitamins, and herbs. Important interactions include:
- Serotonergic agents: tramadol, triptans, fentanyl, lithium, tryptophan, St Johns wort, and other SSRIs or SNRIs may increase risk of serotonin syndrome when combined.
- MAO inhibitors, linezolid, or IV methylene blue: combination is contraindicated due to severe serotonin syndrome risk.
- Antiplatelets, anticoagulants, and NSAIDs: aspirin, clopidogrel, warfarin, rivaroxaban, ibuprofen, and others may heighten bleeding risk.
- CYP interactions: sertraline can inhibit CYP2D6. This may affect drugs like tricyclic antidepressants, certain antipsychotics, metoprolol, and the activation of codeine or tramadol. Cimetidine may raise sertraline levels.
- Tamoxifen: sertraline may reduce formation of active metabolites; oncology teams often prefer alternatives with less CYP2D6 inhibition.
- Pimozide and other QT-prolonging drugs: avoid pimozide; use caution with other QT-prolonging agents.
- Diuretics or medications that lower sodium: additive risk of hyponatremia.
- Alcohol: can worsen sedation or judgment; avoidance is generally advised.
When in doubt, consult your pharmacist before starting or stopping any medicine.
If you miss a dose
Take the missed dose as soon as you remember unless it is close to your next dose. If it is nearly time for the next scheduled dose, skip the missed dose and resume your usual schedule. Do not double the dose.
Overdose and emergency help
Too much sertraline can cause nausea, vomiting, tremor, rapid or irregular heartbeat, dizziness, fainting, confusion, or seizures. Seek emergency care immediately.
In the United States, you can also contact Poison Control at 1-800-222-1222 or use poisonhelp.org for guidance.
Storage and handling
- Store at 20-25 C (68-77 F) in a dry place away from moisture and light.
- Keep out of bathrooms and away from heat sources.
- Always secure medicines away from children and pets.
- Dispose of unused medicine according to local guidance or pharmacy take-back programs.
Alternatives and similar medications
If sertraline is not suitable or not effective, clinicians may consider switching within the SSRI class or to a different mechanism. A few commonly discussed options include:
- Escitalopram (Lexapro) - SSRI often well tolerated; may be chosen for generalized anxiety or depression.
- Bupropion (Wellbutrin) - norepinephrine-dopamine reuptake inhibitor; tends to be activating and has a lower rate of sexual side effects; not ideal for prominent anxiety or seizure risk.
- Fluoxetine (Prozac) - SSRI with long half-life; can be helpful for depression and OCD; slower washout may be beneficial for tapering.
- Venlafaxine XR (Effexor XR) - SNRI that can be effective for anxiety disorders; monitor blood pressure at higher doses.
- Mirtazapine (Remeron) - noradrenergic and serotonergic agent; can improve sleep and appetite; sedation and weight gain are common.
- Duloxetine (Cymbalta) - SNRI that may help when chronic pain coexists with depression or anxiety.
- Paroxetine, citalopram, fluvoxamine, desvenlafaxine, vortioxetine, and vilazodone - other options a prescriber may consider based on symptoms, side effects, and interactions.
Non-medicine options like cognitive behavioral therapy, sleep hygiene, exercise, and mindfulness can be used alone or combined with medication. Discuss with your clinician which approach is best for you.

Legal and access considerations in the USA
- Prescription status: sertraline/Zoloft is a prescription-only medication (legend drug). It is not a controlled substance under the federal Controlled Substances Act.
- Prescribing: e-prescriptions are accepted in all states. A valid patient-prescriber relationship is required, including via telehealth when permitted by state law.
- Refills: state rules vary. Many states allow refills of non-controlled prescriptions for up to 12 months from the date written if authorized by the prescriber. Your label shows the authorized number of refills.
- Generic substitution: most states allow or require pharmacy substitution of a therapeutically equivalent generic unless the prescriber writes "dispense as written".
- Importation: personal importation of prescription drugs from abroad is generally prohibited by federal law except for narrow exceptions. Use licensed U.S. pharmacies.
- Insurance and prior authorization: most plans cover generic sertraline with low copays; brand Zoloft may require higher copays or prior authorization.
- Driving and work: if you feel dizzy or drowsy when starting or changing dose, avoid driving or operating machinery until you know how sertraline affects you.
- Minors: parental or guardian consent is typically required for treatment of minors, subject to state-specific exceptions for mental health services.
