New insights into antidepressants' role in anxiety treatment and patient management

While often linked to depression, antidepressants like SSRIs and SNRIs are increasingly recognised as vital tools in managing persistent anxiety, with treatment plans emphasising patience, therapy, and careful monitoring of side effects.

Antidepressants are often associated with depression, but they are also commonly used to treat anxiety disorders, according to Lightfully’s explainer. For people whose worry, panic or physical tension has become persistent and hard to manage, medication may be one part of a wider treatment plan that also includes therapy, coping strategies and day-to-day support.

The company says antidepressants may be considered for conditions such as generalised anxiety disorder, panic disorder and social anxiety disorder. The medicines most often discussed are selective serotonin reuptake inhibitors, known as SSRIs, and serotonin-noradrenaline reuptake inhibitors, or SNRIs. Mayo Clinic explains that SSRIs work by increasing the amount of serotonin available between brain cells, while Healthline notes that commonly prescribed examples include escitalopram, fluoxetine and sertraline.

But the benefits are rarely immediate. Healthline says it may take 4 to 6 weeks before people notice meaningful change, and Mayo Clinic cautions that early side effects such as nausea, sleep disturbance or weight changes often ease after the first few weeks. Other possible adverse effects can include drowsiness, constipation, dizziness, dry mouth and sexual dysfunction, according to the National Center for Biotechnology Information, which adds that side effects vary by drug and class.

Lightfully also stresses that medication is rarely enough on its own. Anxiety often affects sleep, relationships, work and self-confidence, so therapy can be important for identifying thought patterns, reducing avoidance and building practical coping skills. Cleveland Clinic likewise says finding the right antidepressant can take time and patients should discuss benefits and side effects with a clinician before and during treatment.

The article warns against stopping antidepressants suddenly without medical advice, since that can trigger withdrawal-like symptoms and a return of anxiety, as Mayo Clinic notes. It also urges urgent help if anxiety is accompanied by suicidal thoughts, self-harm urges or feeling unsafe. In those cases, Lightfully advises contacting emergency services or a crisis line straight away.
