Assessment Library Mood & Depression Medication Questions Antidepressants And Anxiety Symptoms

Worried the antidepressant may be increasing your child’s anxiety?

If your child or teen seemed more anxious after starting an antidepressant or after a dose change, you’re not overreacting. Some kids have a temporary increase in anxiety symptoms, and the next step depends on timing, severity, and what else you’re noticing.

Start with one key question about when the anxiety changed

Answer a few questions to get personalized guidance on whether the anxiety may be related to the medication, what patterns parents often notice early on, and when it may be time to contact the prescriber.

When anxiety gets worse after starting an antidepressant

Parents often search for answers when a child has anxiety after starting an antidepressant, or when a teen seems more on edge after a dose increase. In some cases, antidepressant side effects can include restlessness, agitation, trouble sleeping, or a short-term increase in anxiety symptoms. That does not automatically mean the medication is wrong, but it does mean the pattern deserves careful attention. The most helpful clues are when the symptoms began, whether they changed after a dose adjustment, and how intense they are compared with your child’s usual anxiety.

Signs the antidepressant may be contributing to anxiety

The timing lines up

Anxiety started soon after beginning the medication or became more noticeable after the dose was increased.

Your child seems activated, not just worried

You may notice pacing, jitteriness, irritability, feeling keyed up, or difficulty settling, especially if this feels different from their usual anxiety pattern.

Sleep and daily functioning changed quickly

New trouble falling asleep, more meltdowns, school avoidance, or a sudden spike in distress can be important clues to share with the prescriber.

What parents often want to know right away

Can antidepressants make anxiety worse?

Yes, for some children and teens, anxiety can feel worse at first or after a dose increase. This can happen with certain antidepressants, especially early in treatment.

How long does anxiety last after starting antidepressants?

A short-term increase may ease over days to a few weeks, but the timeline varies. Ongoing or worsening symptoms should be reviewed with the prescribing clinician.

What should I do if the antidepressant increases anxiety?

Track when symptoms started, what changed, and how severe they are. Contact the prescriber for guidance rather than making medication changes on your own.

When to reach out promptly

Anxiety is escalating fast

If your child’s distress is rising quickly, interfering with sleep, school, or daily functioning, it’s a good time to contact the prescriber soon.

You’re seeing unusual agitation or behavior changes

Marked restlessness, intense irritability, panic-like symptoms, or behavior that feels very unlike your child should be discussed promptly.

You’re unsure whether this is a side effect or the underlying condition

That uncertainty is common. A structured assessment can help you organize what changed and prepare for a more productive conversation with the clinician.

Frequently Asked Questions

Can antidepressants cause anxiety in a child or teen?

They can in some cases. A child or teen may seem more anxious, restless, activated, or irritable after starting an antidepressant or after a dose increase. The timing and type of symptoms matter when figuring out whether the medication may be playing a role.

How can I tell if the antidepressant is causing anxiety versus my child’s original anxiety getting worse?

Look for a clear change after the medication was started or adjusted, especially if the anxiety feels different from your child’s usual pattern. New jitteriness, agitation, sleep disruption, or a sudden increase in distress can be useful clues to discuss with the prescriber.

How long does anxiety after starting an antidepressant usually last?

For some kids, early anxiety symptoms improve within days to a few weeks. If symptoms are intense, keep getting worse, or are not settling, it’s important to check in with the prescribing clinician.

What should I do if my child’s antidepressant seems to be making anxiety worse?

Document when the symptoms began, whether there was a recent dose change, and what you’re seeing day to day. Then contact the prescriber for guidance. It’s best not to stop or change the medication without medical advice.
