Teen Depression Treatment: A Parent's Guide to Therapy and Medication

For a teenager with depression, the main treatments are psychotherapy (especially cognitive behavioral therapy), an antidepressant, or both. Mild depression is often handled first with close monitoring and support, while moderate to severe depression calls for evidence-based therapy, medication, or the combination. In the largest US trial of teens with depression, combining fluoxetine with CBT gave the best balance of benefit and risk.

Two antidepressants are FDA-approved for depression in adolescents: fluoxetine, approved from age 8, and escitalopram, approved from age 12. All antidepressants carry a boxed warning that they increased suicidal thoughts and behaviors in children, adolescents and young adults in short-term studies, which is why close monitoring in the first weeks matters. This guide explains each option, what the research shows, and what parents can do.

Is it depression or a hard stretch?

Teenagers have bad weeks, and moodiness alone is not depression. Signs that deserve a professional evaluation include:

• Sadness, emptiness or irritability most days for two weeks or more (in teens, irritability can be the main sign)
• Losing interest in friends, sports or activities they used to enjoy
• Big changes in sleep or appetite, constant fatigue
• Falling grades, skipped classes, trouble concentrating
• Withdrawing from family and friends, more time alone in their room
• Talk of hopelessness, worthlessness or being a burden; self-harm; any mention of death or suicide

A pediatrician is a good first stop: they can screen for depression, check for medical contributors such as thyroid problems, anemia or substance use, and refer. Guidelines for adolescent depression in primary care cover young people aged 10 to 21 and include screening, treatment and when to involve mental health specialists.

Teen depression treatments at a glance

What the TADS study found

The Treatment for Adolescents with Depression Study (TADS) randomly assigned 439 adolescents aged 12 to 17 with major depression to 12 weeks of fluoxetine, CBT, both, or placebo. At 12 weeks, response rates were about 71% with the combination, 61% with fluoxetine alone, 43% with CBT alone, and 35% with placebo. The authors concluded that fluoxetine plus CBT offered the most favorable trade-off between benefit and risk.

The longer follow-up adds two points parents should know. By week 36, response rates were similar across the three active treatments: 86% for the combination and 81% each for fluoxetine and CBT. Remission rates converged by week 24. In other words, CBT alone was slower but caught up. And suicidal events were more common with fluoxetine alone (14.7%) than with the combination (8.4%) or CBT (6.3%); the authors wrote that adding CBT to medication enhanced its safety.

What TADS does not tell you: it studied one medication, in teens with moderate to severe depression at academic and community clinics. Results may differ for milder depression, other medications, or teens with other conditions such as substance use or bipolar disorder.

Therapy for teen depression

CBT for adolescents teaches teens to notice and test negative thoughts, rebuild routines and activities that bring a sense of accomplishment or enjoyment, and solve problems in small steps. Behavioral activation, a component of CBT, is often where therapy starts when a teen has withdrawn from everything; see behavioral activation for depression. Interpersonal therapy focuses on conflicts, transitions and losses, and is a good fit when depression followed a breakup, a move or family strain.

Signs a therapy is a good fit:

• The therapist explains the approach in plain terms and sets goals with your teen.
• Sessions include practice between appointments, not only talking.
• Progress is measured, for example with a depression questionnaire such as the PHQ-9 adapted for adolescents; see PHQ-9 and GAD-7 scores explained.
• Parents have a defined role, such as a periodic family session, while your teen keeps a private space.

For teens with self-harm or intense emotional swings, dialectical behavior therapy adapted for adolescents may fit better; the site's article on DBT for teens explains it.

Antidepressants for teens: approvals, warnings and monitoring

Fluoxetine's label notes that safety and effectiveness have not been established in children under 8 with depression; it is approved for pediatric depression above that age. Escitalopram is approved for depression in adults and adolescents 12 and older. Other antidepressants, including sertraline, are used off-label for teen depression; sertraline's label says pediatric data were not sufficient to support its use for depression, though it is approved for OCD from age 6. For how the two most familiar options compare, see fluoxetine vs sertraline.

The boxed warning, in plain terms

Every antidepressant label carries a boxed warning that these drugs increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients in short-term studies. The label's data show the increase in patients under 18 and those aged 18 to 24, and a decrease in adults 25 and older. The warning tells clinicians to monitor all patients closely for clinical worsening and new suicidal thoughts and behaviors.

The warning does not mean antidepressants should be avoided in teens. Untreated depression carries its own serious risks, and in TADS, suicidal thinking improved in all treatment groups. It means the first weeks need a clear plan:

1. Agree on how often the prescriber will check in, and who to call between visits.
2. Watch for new or worse agitation, restlessness, irritability, insomnia, panic, impulsive behavior, or talk of suicide, and report them promptly.
3. Keep medications, including over-the-counter pain relievers, locked or under adult control.
4. Do not stop the medication suddenly or change the dose without the prescriber.

A prescriber should also screen for a personal or family history of bipolar disorder before starting an antidepressant, because antidepressants can trigger mania in people at risk.

What parents can do at home and at school

• Listen more than you fix. Ask open questions and reflect back what you hear before offering solutions.
• Protect the basics: regular sleep and wake times, meals, daylight and physical activity, with expectations scaled to how your teen is doing.
• Limit access to lethal means at home, including firearms, stockpiled medications and alcohol.
• Stay involved in treatment without taking it over: help with scheduling and transport, attend parent sessions, and respect the privacy of individual therapy.
• Talk to the school counselor about short-term adjustments, such as extended deadlines or a reduced load, and ask whether a formal plan makes sense; the guide to school plans explains the two main types, which can also apply to conditions other than ADHD.
• Look after yourself. Parent burnout makes everything harder; your own therapy or a support group can help.

Include your teen in treatment decisions as much as their age and condition allow. Teens who understand why a therapy or medication was chosen, what side effects to watch for, and how progress will be judged may find it easier to stick with. Ask the clinician to explain options to your teen directly, and let your teen ask questions without you answering for them.

Consent and privacy in New York

Under New York Mental Hygiene Law section 33.21, a minor is generally someone under 18, with exceptions such as minors who are married, emancipated or parents themselves. The law lets a practitioner provide outpatient mental health services to a minor without parental consent in narrow circumstances, for example when a parent is not reasonably available or involvement would harm treatment, but this provision applies to outpatient programs licensed or operated under Office of Mental Health rules. Outside that setting, the provision does not apply, so ask any practice how it handles consent, what it shares with parents, and what stays between the clinician and your teen. Ask too how safety concerns are handled.

If the first treatment is not working

Primary care guidelines for adolescent depression include specific steps when a teen has only partly improved or not improved after starting treatment, and recommend tracking outcomes over time rather than relying on impressions. In practice, a clinician will usually work through these questions:

• Is the diagnosis right? Anxiety, ADHD, trauma, an eating disorder, substance use, or the early signs of bipolar disorder can sit alongside depression or mimic it.
• Has the treatment had a fair trial? That means enough therapy sessions with real practice between them, or a medication taken consistently for long enough at a suitable dose.
• Is something maintaining the depression? Bullying, conflict at home, sleep loss from late-night screens, or a learning problem that makes school a daily struggle may need direct attention.
• Would adding the other treatment help? In TADS, combining CBT and fluoxetine gave the strongest early response.

Next steps can include adding or changing therapy, adjusting the dose, switching medication, involving a child and adolescent psychiatrist, or a more intensive program. Partial improvement deserves attention: in TADS, residual symptoms at the end of acute treatment predicted failure to reach remission later. If your teen seems better but not well, say so. The article on signs treatment isn't working covers what to ask for.

Choosing who treats your teen

A pediatrician can screen, start treatment for mild to moderate depression, and coordinate with specialists, as primary care guidelines describe. A child and adolescent psychiatrist is especially helpful when depression is moderate to severe, when there are suicidal thoughts, when a first medication has not worked, or when ADHD, anxiety, an eating disorder, substance use or possible bipolar disorder complicate the picture. See choosing a child and adolescent psychiatrist for what training to look for.

Questions to ask at the first appointment:

1. How severe do you think the depression is, and what do you recommend first?
2. If medication is suggested, why this one, and how will you monitor for side effects and suicidal thoughts?
3. Who provides therapy, and how will the therapist and prescriber communicate?
4. How will we measure progress, and when would we change the plan?
5. What do you share with parents, and what stays private?

When to get help right away

Go to an emergency room if your teen talks about a plan to end their life, has tried to hurt themselves, cannot stay safe, or shows signs of psychosis. The guide to psychiatric emergency vs urgent care in NYC explains options, and safety planning for suicidal thoughts shows how to build a written plan with your teen.

If you are thinking about suicide or are in crisis, call or text 988 (the 988 Suicide & Crisis Lifeline) or go to the nearest emergency room.

How the practice can help

Dr. Lewis is board certified in adult psychiatry, child and adolescent psychiatry, and integrative medicine, and trained at Columbia University and the NYU Child Study Center. The practice's team includes psychiatrists, psychiatric nurse practitioners and psychotherapists, and care can combine psychiatric evaluation and medication management with psychotherapy including CBT and DBT, coaching, and nutrition and lifestyle psychiatry. The child and adolescent psychiatry page and the article on treating adolescents with depression describe the approach. Individual care starts with the Patient Interest Form. If you need care that is in network with your plan, ask the team on the discovery call about options. For more starting points, see the Choosing Psychiatric Care guide.

Frequently asked questions

Should my teen start with therapy or medication?

For mild depression, monitoring and support or therapy is a common first step. For moderate to severe depression, guidelines support therapy, medication or both; in TADS, the combination gave the best balance of benefit and risk. Decide with your teen's clinician.

Does the boxed warning mean antidepressants are dangerous for teens?

It means antidepressants increased suicidal thoughts and behaviors in short-term studies of young people, so close monitoring is needed, especially early on. Untreated depression also carries serious risks, which is why the decision is made with a clinician.

How long will my teen need treatment?

It varies. In TADS, most teens in all active treatment groups had responded by 36 weeks. If medication helps, how long to continue it, and how to stop it, is planned with the prescriber.

Can my teen get therapy without me knowing?

New York law lets some minors receive outpatient mental health care without parental consent in limited circumstances, but only in outpatient programs licensed or operated under Office of Mental Health regulations, and the clinician must document the reasons. Ask the practice about its policy.

What if my teen refuses to go?

Start with a low-pressure conversation, offer choices (video or in person, which clinician), and consider a parent-only consultation first. If there is any safety risk, seek urgent help regardless.

Can my teen's school help?

Yes. A school counselor can arrange short-term adjustments, and a formal plan may be appropriate if depression is affecting learning. Share only what your teen is comfortable with where possible.
