How Long Should You Take Antidepressants?

Written by the Lyte Psychiatry clinical team. Clinically reviewed by Ana G., LPC, and medically reviewed by Dr. Akinwande Akintola, MD, supervising physician. Last reviewed: November 4, 2026.

How long to take antidepressants depends on why you started, how many episodes you have had and how well you are doing now. MedlinePlus says the typical course is 6 to 12 months, though some people stay on them much longer. Most people are not on them forever, and any decision to stop should be made with your prescriber.

This article is for adults who have started an antidepressant, are thinking about starting one, or feel better and are wondering whether they still need it. This article is general information, not a medical recommendation. Do not start, stop or change any medication without talking to your prescriber.

What are antidepressants?

Antidepressants are prescription medicines used to treat depression and several other conditions, including some anxiety disorders. The National Institute of Mental Health (NIMH) describes several classes of mental health medications and notes that early side effects are common and often fade over time.

Antidepressants are not "happy pills," and they do not change your personality. When they work, people often describe feeling more like themselves: able to sleep, eat, focus and respond to life's ups and downs with less heaviness. They are often used alongside therapy rather than instead of it.

How long do antidepressants take to work?

Antidepressants usually take several weeks to work fully. As of October 2026, MedlinePlus, the National Library of Medicine's consumer health site, says they usually take 4 to 8 weeks, and that sleep and appetite may improve before mood does.

That timeline matters because many people give up too early. If you have been taking a medicine for only a week or two, it is usually too soon to judge. Keep notes on sleep, energy, appetite and mood, and share them at your follow-up visit. MedlinePlus also notes that some people need to try two or more medicines before finding one that works.

How long do most people stay on antidepressants?

Most people take antidepressants for several months after they start feeling better, not just until the first good week. As of October 2026, MedlinePlus states that "the typical length of treatment is 6 to 12 months, but some people may stay on antidepressants for much longer," and that you decide the length with your provider.

When people ask how long to take antidepressants, they are often really asking why they should continue once they feel fine. The reason for continuing after you feel better is to lower the chance that symptoms come back. MedlinePlus warns that stopping too fast may make depression return. Feeling well is a sign the treatment is working, not necessarily a sign that you no longer need it.

Why might someone take antidepressants long term?

Some people take antidepressants for years because their history suggests a higher risk of symptoms returning. The MedlinePlus Medical Encyclopedia notes that depression or anxiety may come back in the future after you stop medicine, which is why the decision is made carefully.

Factors a prescriber may weigh include:

• How many episodes of depression you have had.
• How severe past episodes were, including any suicidal thoughts or hospital stays.
• How long it took to feel well this time.
• Whether other conditions, like anxiety, are part of the picture.
• What is happening in your life right now, such as a major move, a new baby or a job change.
• Your own preferences about side effects and long-term treatment.

There is no single answer to how long to take antidepressants. Long-term treatment is a choice, not a failure. For some people, staying on a medicine that works is the most stable option.

What are the common side effects?

Side effects are common, especially at the start, and are usually mild. As of October 2026, MedlinePlus lists nausea and vomiting, weight gain, diarrhea, sleepiness and sexual problems among the most common side effects of antidepressants, and says they may ease over time.

Tell your prescriber about any side effect that bothers you. There are often ways to help, and you should not have to quietly put up with something that makes you want to quit. NIMH notes that all medications can have side effects and that finding the best treatment can take some trial and error.

The U.S. Food and Drug Administration (FDA) requires a boxed warning about increased suicidal thinking in some children, teens and young adults taking antidepressants, and advises contacting the prescriber about new or worsening symptoms such as agitation. Families should watch closely, especially in the first weeks.

How to stop antidepressants safely, step by step

The safe way to stop is gradually, with your prescriber's guidance. MedlinePlus states that "the safe way to stop taking this medicine is to lower the dose over time," and warns against stopping suddenly.

1. Talk first. Bring up stopping at a regular visit instead of deciding on your own.
2. Pick a stable time. Avoid stopping during a crisis, a move, a breakup or a stressful season at work.
3. Agree on a plan. Your prescriber will explain how to lower the dose over time and how long that will take.
4. Know the possible withdrawal symptoms. MedlinePlus lists flu-like feelings, sleep problems, dizziness and headache among symptoms that can follow stopping too quickly.
5. Track how you feel. Note mood, sleep, energy and irritability each week during and after the taper.
6. Keep follow-up visits. Stay in contact for months afterward so early signs of relapse can be caught.
7. Have a return plan. Agree in advance on what you will do if symptoms come back.

Never change your dose or quit on your own, even if you feel fine. Our article on what happens at a medication management visit explains what these check-ins look like.

Can therapy help you stay well after stopping?

Therapy can be an important part of staying well, during and after medication. NIMH explains that psychotherapy can help people work on self-defeating thoughts and behaviors, even when they are also taking medication.

Research supports this. A UK randomized trial published on the NIH National Library of Medicine's Bookshelf in 2015 found that mindfulness-based cognitive therapy, combined with support to taper off medication, was about as effective as staying on maintenance antidepressants for preventing a return of depression in people with recurrent depression. That does not mean therapy replaces medicine for everyone, but it is a real option to discuss.

Questions to ask your prescriber

A short list of questions can make the conversation about how long to take antidepressants easier. MedlinePlus notes that the length of treatment is something you and your provider decide together once the medicine starts working.

• "How will we know when I've been well long enough to consider stopping?"
• "Based on my history, what is my risk of symptoms coming back?"
• "What would a taper plan look like for my medicine?"
• "What withdrawal symptoms should I watch for, and when should I call?"
• "What are the signs of relapse I should watch for?"
• "Should I start or restart therapy before we change anything?"

When to get help sooner

Get help right away if your mood changes quickly or you feel unsafe, whether you are starting, continuing or stopping a medicine. MedlinePlus lists returning symptoms and, for some people, increased suicide risk among the reasons not to stop medicine suddenly.

Contact your prescriber promptly, or seek urgent care, if you notice:

• Thoughts of suicide, self-harm or feeling that others would be better off without you.
• New agitation, restlessness or intense anxiety after starting or changing a medicine.
• Very high energy, much less need for sleep, racing thoughts or unusually risky behavior.
• Low mood that returns and lasts more than a couple of weeks after stopping.
• Withdrawal symptoms that are severe or keep you from functioning.

If your medicine has never fully helped, ask about other options. NIMH notes that when two different antidepressants have not helped, the condition may be called treatment-resistant depression, and other approaches are available. Our guide to treatment-resistant depression explains more.

Staying on track with treatment in Texas

For Texans, telehealth can make it easier to keep regular medication follow-ups, especially during busy seasons or long commutes. The U.S. Department of Health and Human Services (HHS) notes that, as of October 2026, the ability to deliver care across state lines varies based on state regulations, so tell your clinician if you will be outside Texas during a scheduled visit.

If you are moving out of state or switching clinicians, plan ahead so you do not run out of medicine or stop abruptly. Our article on switching psychiatrists without interrupting treatment covers how to keep care continuous.
