# Panic Disorder Maintenance Treatment > Panic disorder maintenance in NEET-PG Psychiatry: low-dose SSRI starts, 12-18 month treatment duration, interoceptive exposure and relapse management. - Canonical URL: https://prepelephant.com/topics/neet-pg/psychiatry/panic-maintenance - Exam / course: NEET-PG · Subject: Psychiatry - Publisher: PrepElephant (https://prepelephant.com) — Prepared and reviewed by the PrepElephant Academic Review Team - First published: 2026-10-02 - Last updated: 2026-10-02 - How to cite: "Panic Disorder Maintenance Treatment", PrepElephant, https://prepelephant.com/topics/neet-pg/psychiatry/panic-maintenance ## Direct answer The first ten days of an SSRI in panic disorder can make the patient worse before better — heightened jitteriness and more frequent spikes of autonomic arousal are why starting doses are halved: paroxetine 10 mg, sertraline 12.5-25 mg, escitalopram 5 mg, climbing later. A full trial needs 8-12 weeks at a therapeutic dose, and once panic attacks have stopped and agoraphobic avoidance has dissolved, maintenance continues for 12-18 months, since roughly a third to a half of patients relapse after early discontinuation in follow-up studies. CBT with interoceptive exposure — deliberately inducing feared bodily sensations — is the component that protects gains after the tablets stop, which is why the strongest maintenance plan pairs both from the beginning. ## What you must remember - **Start at half dose:** paroxetine 10 mg, sertraline 12.5-25 mg, escitalopram 5 mg; titrate every 1-2 weeks — early activation is otherwise read as worsening and the drug abandoned. - **Licensed SSRI choices:** paroxetine, sertraline, citalopram, escitalopram and fluoxetine all have panic evidence; clomipramine is the tricyclic alternative when SSRIs fail. - **Maintenance window:** 12-18 months after full remission (no attacks AND no anticipatory fear), longer with comorbid agoraphobia or depression. - **Relapse numbers:** with drug discontinuation, relapse in the region of 30-50% is reported across follow-up studies; CBT (particularly interoceptive exposure) lowers this figure. - **Interoceptive exposure protocol:** repeated spinning, straw-breathing, running stairs or CO2-inhalation to reproduce the feared sensations until they lose their alarm — the panic-specific form of exposure. - **Benzodiazepine caution:** alprazolam works fastest and causes the most trouble — if used at all, it is a short bridge with a fixed exit plan; avoid PRN dosing patterns that teach the patient panic is dangerous. - **Nocturnal panic:** sleep panic attacks occur in a substantial minority of patients and do NOT exclude the diagnosis — a favourite true/false discriminator. - **The maintenance aim:** end both the attacks and the fear of the attacks; residual agoraphobic avoidance at treatment's end predicts relapse better than attack frequency. ## The maintenance phase, week by week Envisage a 26-year-old woman with daily panic attacks for six months, now housebound after a supermarket episode. Weeks 1-2: sertraline 12.5 mg, psychoeducation that panic is adrenaline misread, not heart disease — the cardiac work-up she has already collected (three ECGs, two echo reports) is reviewed and closed. Weeks 3-8: dose rises to 50-100 mg while CBT begins with breathing retraining and interoceptive drills; her homework is deliberately over-breathing in the clinic until dizziness loses its meaning. Weeks 8-16: graded in-vivo exposure — the supermarket aisle by aisle, the bus stop, the cinema seat — each blocked safety behaviour (carrying water, checking pulse) removed, because safety behaviours quietly maintain the fear. Months 4-18 constitute maintenance: dose held, exposures converted from therapy tasks into ordinary life, follow-up thinned from fortnightly to quarterly. At month 12 a taper decision is made jointly: reduce by 25% steps monthly, with a pre-written plan for the first warning signs (avoided aisle, pulse-checking's return) and two rapid-review appointments reserved. Relapse, if it comes, resumes full-dose SSRI plus two refresher CBT sessions — framed to her as a flare of a tendency, not the failure of treatment. ## How the exam frames it The panic questions test start-dose arithmetic (half dose, to avoid early activation), duration arithmetic (12-18 months after remission), and the interoceptive concept itself: "which technique pairs deliberate hyperventilation with a patient who fears dizziness" is answered by interoceptive exposure, not relaxation training — relaxation appears in the options precisely as the decoy. Expect also the differential move: thyroid disease, arrhythmia, phaeochromocytoma and caffeine excess are excluded before the diagnosis, and a stem describing "fear of going crazy with paraesthesias and carpopedal spasm" is pointing toward panic with hyperventilation, not toward a neurological disease. ## Frequently asked questions ### Why do SSRIs for panic disorder start at half the usual dose? Because early activation — jitteriness, insomnia and increased anxiety in the first days — is common in panic disorder and causes patients to abandon treatment. ### How long is maintenance treatment continued in panic disorder? For 12-18 months after full remission, defined as absence of both panic attacks and anticipatory anxiety, with longer treatment for comorbid agoraphobia or depression. ### What is interoceptive exposure? Repeated deliberate induction of the feared bodily sensations — spinning, straw breathing, stair-running — until the sensations lose their catastrophic meaning; it is the panic-specific exposure modality. ### How does CBT affect relapse after SSRI discontinuation in panic disorder? Panic-focused CBT with interoceptive exposure substantially reduces post-discontinuation relapse compared with medication alone, because learned safety persists after treatment. ### Do nocturnal panic attacks suggest a different diagnosis? No — sleep (nocturnal) panic attacks occur in a substantial minority of panic disorder patients and are part of the same condition.
