Why depression and anxiety may respond differently
Depression and anxiety are related but distinct conditions, with different neurobiological substrates. Some antidepressants have stronger antidepressant than anti-anxiety effects, particularly at lower doses. NICE NG222 and RANZCP both note that anxiety symptoms may take longer than mood symptoms to respond, and that higher doses are sometimes needed for full anxiety coverage. Continued improvement in anxiety is often seen at three to six months even when mood has already lifted.
What the evidence suggests as next steps
Dose adjustment is typically the first step — many anxiety symptoms respond to higher doses than depression symptoms. Time is the second factor — anxiety often takes longer to respond, with continued improvement documented well past the initial response window. Adding therapy, particularly CBT for anxiety, is documented in NICE guidance to improve outcomes for patients with persistent anxiety on antidepressants.
What to discuss with your prescriber
How much the mood improvement has held. Describe how long the mood change has been stable and how significant the improvement has been.
How much the anxiety is affecting daily life. Be specific — sleep, work, social function. This guides the urgency of adjustment.
Whether a dose adjustment is appropriate. Discuss whether a higher dose might close the gap between mood and anxiety response.
Whether therapy alongside medication would help. CBT for anxiety is supported by NICE guidance for exactly this partial-response situation.
Bringing a written summary of the past weeks to your appointment makes this conversation more productive and ensures the pattern is documented clearly.

Frequently asked questions
Why is my depression better but my anxiety the same?
Depression and anxiety can respond differently to the same medication. Anxiety often takes longer or higher doses to respond fully. This is a documented pattern, not a sign that treatment has failed.
Should I add another medication for anxiety?
Discuss with your prescriber. Dose adjustment of the existing medication is usually tried first. Augmentation strategies or adding therapy are considered if that is not sufficient.
Will my anxiety eventually respond to my antidepressant?
Often yes, with time or dose adjustment. Some patients need additional strategies — adding CBT for anxiety is well-documented to help in this situation.
