Treatment of Illness Anxiety Disorder

Introduction to Treatment

The American College of Cardiology is not mentioned, however, the recommended first-line treatment for Illness Anxiety Disorder is Cognitive Behavioral Therapy (CBT) specifically designed for health anxiety, with SSRIs (particularly sertraline or escitalopram) as the primary pharmacotherapy option when medication is needed 1

Individual CBT sessions are preferred over group therapy due to superior clinical effectiveness in anxiety disorders, according to the guidelines from the medical community 2, 1
If face-to-face CBT is not feasible or desired by the patient, self-help CBT with professional support is a viable alternative, as suggested by the medical guidelines 2, 1

SSRIs are the primary pharmacological treatment, with sertraline and escitalopram preferred due to their favorable safety profiles and effectiveness, as stated in the medical guidelines 1
Sertraline or escitalopram should be initiated as first-choice SSRIs for their lower potential for drug interactions and superior tolerability, according to the medical community 1
SNRIs (particularly venlafaxine extended-release) are equally effective alternatives to SSRIs and can be used as first-line treatment, as suggested by the medical guidelines 1
Fluvoxamine is approved for anxiety disorders but may have more side effects than sertraline or escitalopram, according to the medical guidelines 1

Paroxetine and fluoxetine should be avoided, especially in older adults, due to higher rates of adverse effects, as stated in the medical guidelines 1
If benzodiazepines are absolutely necessary for very short-term use, use lower doses with shorter half-lives, according to the medical community 1

Medications should be continued for at least 6-12 months after symptom remission for a first episode, as suggested by the medical guidelines 1
For recurrent or chronic presentations, longer-term or indefinite treatment may be necessary, according to the medical community 1

Start with individual CBT specifically designed for health anxiety as the primary intervention, as stated in the medical guidelines 2, 1
Add an SSRI (sertraline or escitalopram) or SNRI (venlafaxine) if CBT alone is insufficient or if patient preference/severity warrants combined treatment, according to the medical community 1
If the first medication fails, switch to another SSRI or SNRI rather than adding additional agents, as suggested by the medical guidelines 1
Continue treatment for at least 6-12 months after remission, with longer duration for recurrent cases, according to the medical guidelines 1
