Panic disorder involves recurrent unexpected panic attacks, sudden surges of intense fear with physical symptoms, followed by persistent worry about future attacks or avoidance. It is treated with SSRIs or SNRIs and cognitive behavioral therapy that includes interoceptive exposure, with most people seeing major improvement within 12 weeks. Panic attacks are not medically dangerous. Stedfast Psychiatry treats panic disorder at 120 Brookside Parkway in Lexington and by video across South Carolina; new patients call (561) 234-4467.

How we diagnose it
A panic disorder evaluation at Stedfast Psychiatry includes a detailed description of your attacks (onset, peak, duration, symptoms, triggers), what you fear during them, how you have changed your life to avoid them, and whether agoraphobia has developed. We use the Panic Disorder Severity Scale, the GAD-7 and the PHQ-9 to measure baseline and progress. We review your caffeine, alcohol, cannabis and medication use, and your medical history. If you have not already had a medical workup, we coordinate with your primary care provider on an EKG, thyroid tests and a basic metabolic panel to rule out cardiac and endocrine causes. We also screen for depression, PTSD, social anxiety and substance use, which commonly accompany panic.

Treatment for panic disorder in Lexington
Medication management
SSRIs are first-line: sertraline, paroxetine and fluoxetine are FDA-approved for panic disorder, and escitalopram and the SNRI venlafaxine XR are well supported. People with panic are unusually sensitive to activation in the first days of an SSRI, so we start at half the usual dose or lower and increase slowly over four to six weeks. Attacks usually decrease in frequency by week four to six, with full benefit at 8 to 12 weeks. A benzodiazepine such as clonazepam may be used briefly as a bridge during the first few weeks or for rare severe attacks, but we avoid daily long-term use because of tolerance, dependence and interference with therapy. Propranolol can help with physical symptoms in performance situations. Medication is continued for at least 12 months after remission and tapered slowly.
Psychotherapy
CBT for panic disorder is highly effective, often in 8 to 12 sessions. It includes education about the fight-or-flight response, correcting catastrophic interpretations of body sensations, slow breathing retraining, and interoceptive exposure: deliberately producing the feared sensations (spinning, running in place, breathing through a straw) until the brain learns they are harmless. When agoraphobia has developed, graded exposure to avoided places follows. CBT produces results comparable to medication and has lower relapse rates after treatment ends. Many patients combine both.
What to expect
Your first visit is a 45 to 60 minute evaluation, in person or by video. You leave with a clear explanation of what is happening in your body during an attack, a plan, and a prescription if medication is appropriate. Follow-ups are every two to three weeks while the SSRI is being titrated, then monthly, then every two to three months. CBT sessions are weekly for two to three months. Telehealth works well for panic disorder, and for patients with agoraphobia it removes the barrier of leaving home to get help.

Frequently asked questions
Who provides panic disorder treatment at the Lexington office?
The Lexington team includes psychiatrist Dr. Eric R. Williams and psychiatric nurse practitioner Samantha Harlow. Every provider works under psychiatrist oversight and the same evaluation standard: about an hour for a first visit, validated screening scales, and a written plan.
Can I be seen by video instead of coming to Lexington?
Yes. Stedfast Psychiatry providers are licensed in South Carolina and offer video visits for evaluations and follow-ups. Some situations, including certain controlled-substance prescriptions and first visits for young children, require an in-person appointment at 120 Brookside Parkway.
Does the Lexington office take my insurance?
We accept most major commercial plans and Medicare. Call (561) 234-4467 with your member ID and we will verify benefits before the visit. Self-pay new-patient evaluations are $185.
How soon can a new patient be seen in Lexington?
Most new patients are scheduled within one to two weeks. If you need to be seen sooner, ask about a video visit; those often open up within days. If you are in crisis, call or text 988 or go to the nearest emergency room rather than waiting.
Can I get Deep TMS or Spravato as a Lexington patient?
Yes. Stedfast Psychiatry is licensed for both. Your Lexington provider does the evaluation and the prior authorization; treatment sessions are scheduled at our Palm Beach Gardens TMS center and the Palm Beach Gardens Spravato rooms.
Is a panic attack dangerous? Could it be a heart attack?
A panic attack is not dangerous, although it feels like it. The racing heart, chest tightness and shortness of breath are the normal fight-or-flight response firing at the wrong time. A first episode of chest pain deserves a medical evaluation, including an EKG, to rule out cardiac causes. Once that is normal, further attacks with the same pattern are panic, and treating the panic ends the cycle of ER visits.
What is the best medication for panic attacks?
SSRIs such as sertraline, paroxetine and escitalopram are first-line and prevent attacks over 8 to 12 weeks. Benzodiazepines stop an attack within 20 to 30 minutes but are not a good long-term solution because of dependence and because they prevent the brain from learning the attack is harmless. We often start a low SSRI dose and use a benzodiazepine only briefly as a bridge, if at all.
