Generalized anxiety disorder is chronic, excessive worry lasting six months or more with physical symptoms such as tension, restlessness and poor sleep. It is treated with SSRIs or SNRIs, cognitive behavioral therapy, or both, with buspirone and hydroxyzine as alternatives. Most people improve substantially within 8 to 12 weeks, and treatment is available in person or by telehealth.
Stedfast Psychiatry treats GAD with a combination that the evidence supports: a careful diagnosis that rules out medical and substance causes, first-line medication when appropriate, and cognitive behavioral therapy that teaches you to change the relationship with worry itself. Most patients see meaningful relief within two to three months, and we follow you until the anxiety is managed rather than merely reduced.
Symptoms of GAD
- Excessive worry about several things most days for at least six months
- Difficulty controlling or stopping the worry
- Restlessness or feeling keyed up and on edge
- Muscle tension, headaches or jaw clenching
- Fatigue that is out of proportion to activity
- Trouble concentrating or mind going blank
- Irritability
- Trouble falling or staying asleep
- Stomach upset, nausea or frequent urge to use the bathroom
Causes and risk factors
GAD runs in families and about a third of the risk is inherited. The rest comes from temperament (a cautious, harm-avoidant style visible in childhood), early stress or adversity, and learned patterns of coping with uncertainty by worrying. Caffeine, stimulants, alcohol withdrawal and some medications (decongestants, asthma inhalers, thyroid hormone at high doses) can produce or worsen anxiety. Medical conditions such as hyperthyroidism, cardiac arrhythmia and low blood sugar can mimic it. In the brain, GAD involves an overactive threat system (the amygdala) and reduced top-down regulation from the prefrontal cortex, with serotonin, norepinephrine and GABA systems all playing a role. These are the same systems that SSRIs, SNRIs and therapy act on.

How we diagnose it at Stedfast Psychiatry
We diagnose GAD through a structured psychiatric interview that maps what you worry about, how long it has been going on, how much control you have over it, and the physical symptoms that come with it. We use the GAD-7 scale at the first visit and every follow-up to track severity. Because anxiety rarely travels alone, we screen for depression (PHQ-9), panic attacks, social anxiety, OCD, PTSD and ADHD, each of which changes the treatment plan. We review caffeine, alcohol, cannabis and stimulant use and all current medications. When indicated we order thyroid function tests, a complete blood count and a metabolic panel, and we may ask your primary care provider for an EKG if palpitations are a prominent symptom.
Treatment options
Medication management
SSRIs (escitalopram, sertraline, paroxetine) and SNRIs (venlafaxine XR, duloxetine) are first-line for GAD and are FDA-approved for it. We start low because people with anxiety are sensitive to early side effects, and increase over two to four weeks. Physical symptoms and sleep often improve first; the worry itself usually eases by week four to eight, with full effect by twelve weeks. Buspirone is a non-sedating option that can be used alone or added to an SSRI. Hydroxyzine helps with short-term relief and sleep without dependence. Benzodiazepines such as lorazepam or clonazepam work quickly but carry tolerance and dependence risk, so we use them sparingly, for short periods or for a bridge while an SSRI takes effect. We monitor blood pressure on SNRIs and check in on side effects at two and six weeks.
Psychotherapy
Cognitive behavioral therapy for GAD targets intolerance of uncertainty, worry as a (false) problem-solving strategy, and avoidance. Typical treatment is 12 to 16 weekly sessions. Techniques include worry scheduling, cognitive restructuring, applied relaxation, and exposure to uncertainty. Acceptance and commitment therapy and mindfulness-based approaches also have good evidence. For many patients, therapy alone is sufficient; for moderate to severe GAD, combining it with medication produces the best and most durable results.
What to expect
At your first appointment, in person or by video, you will complete the GAD-7 and PHQ-9, then spend 45 to 60 minutes with a psychiatric provider reviewing your history and symptoms. You leave with a diagnosis, a plan, and a prescription if medication is part of it. Follow-ups are at two to four weeks during dose adjustment, then every two to three months. Telehealth works well for GAD and most patients do the majority of their follow-ups by video from home or work anywhere in Florida or South Carolina.
When to seek help
Worry that has lasted months, that you cannot turn off, and that is costing you sleep, focus or relationships deserves an evaluation. Seek help sooner if you are using alcohol or cannabis to calm down, if you have started avoiding things you used to do, or if the anxiety is accompanied by depression. If you have thoughts of harming yourself, call or text 988 or go to your nearest emergency room.
How GAD differs from other anxiety disorders
Anxiety disorders share a core of fear and avoidance but differ in their focus. Panic disorder centers on sudden surges of physical fear and the dread of the next one. Social anxiety disorder is specific to being judged in social or performance situations. Specific phobias attach to one trigger. OCD involves intrusive thoughts and compulsive rituals. GAD is the broadest: the worry spreads across many domains and is more about what might go wrong in the future than about any one feared situation. Many people meet criteria for more than one, and about half of people with GAD have had a depressive episode. Getting the full picture matters because it changes which therapy techniques and sometimes which medication we choose.
Medical conditions that mimic anxiety
Before committing to a diagnosis of GAD, we consider conditions that can produce the same symptoms. Hyperthyroidism causes nervousness, tremor, palpitations and insomnia. Cardiac arrhythmias produce episodes that feel like panic. Low blood sugar, asthma, chronic obstructive pulmonary disease, and withdrawal from alcohol or benzodiazepines all cause anxiety. High caffeine intake, energy drinks, decongestants and some ADHD stimulant doses can push an anxious person over the edge. A short set of labs and a careful medication and substance history usually settles the question.
Lifestyle changes that help
Reducing caffeine, especially after noon, is one of the simplest and most effective changes. Regular aerobic exercise lowers baseline anxiety in clinical trials. A consistent sleep schedule matters because sleep loss amplifies worry the next day. Alcohol provides short-term relief and rebound anxiety the next morning, so cutting back often reduces symptoms more than patients expect. Structured worry time, limiting news and social media consumption, and slow diaphragmatic breathing practiced daily (not only during anxiety) all have a place. None of these replace treatment, but they make treatment work faster.
Prognosis
GAD is a chronic condition for many people, but it is a manageable one. With treatment, most patients see their GAD-7 score drop from the moderate or severe range into the mild range within three months, and many reach full remission. Relapse is more common in people who stop treatment early or who face a major stressor, so we plan for maintenance and teach skills that outlast the course of therapy. Patients who learned CBT skills tend to hold their gains longer after medication is tapered, which is one reason we recommend both when the anxiety is more than mild.
Frequently asked questions
What is the best medication for generalized anxiety disorder?
There is no single best medication, but escitalopram, sertraline, venlafaxine XR and duloxetine are the most commonly used first-line options and have the strongest evidence. Buspirone is a good non-sedating alternative or add-on. Hydroxyzine can be used as needed. The right choice depends on your other symptoms, side-effect sensitivity, other medications and whether depression is also present. We expect to find the right fit within one or two trials.
Are benzodiazepines like Xanax a good treatment for GAD?
They relieve anxiety within an hour, which is why patients like them, but they lose effect with daily use, cause dependence, impair memory and driving, and are dangerous combined with alcohol or opioids. We use them for short-term relief, for a few weeks while an SSRI starts working, or occasionally for specific situations. They are not a long-term treatment for GAD, and telehealth prescribing of controlled substances has additional requirements.
Can anxiety be treated without medication?
Yes. CBT alone is an effective first-line treatment for mild to moderate GAD, and many patients prefer to start there. It takes 12 to 16 sessions and requires practice between visits. If symptoms are severe, if you are not functioning, or if therapy alone has not been enough after a fair trial, adding medication is reasonable. We will tell you honestly which approach fits your situation.
How long does GAD treatment take?
Most people feel noticeably better in 8 to 12 weeks. Medication is usually continued for at least 12 months after you are well, then tapered gradually. Therapy is typically 3 to 4 months of weekly sessions followed by occasional booster visits. GAD tends to be a long-term condition that waxes and wanes, so some patients stay on a low dose or return for brief refreshers during stressful periods.
Can I get anxiety treatment through telehealth in Florida or South Carolina?
Yes. Evaluation, SSRI and SNRI prescribing, buspirone, hydroxyzine, and therapy are all well suited to video visits, and we see patients across both states. Controlled substances such as benzodiazepines have additional prescribing rules and may require an in-person visit, which our staff will explain when you schedule. Many patients do their first visit in person and follow-ups by telehealth, which makes it easier to keep the regular contact that anxiety treatment depends on.
Does insurance cover anxiety treatment?
We accept most major commercial plans and Medicare, and visits are billed as specialist office visits with your usual copay. Our self-pay rate for a new-patient evaluation is $185, with follow-ups priced lower. Generic SSRIs, SNRIs, buspirone and hydroxyzine cost a few dollars a month at most pharmacies. Therapy is covered by most plans as outpatient mental health care, and our staff verifies your benefits before the first visit so there are no surprises.
What is the difference between GAD and normal stress?
Stress is tied to a specific demand and eases when the demand passes. GAD is free-floating: the worry moves from topic to topic, continues when things are going well, and lasts six months or more. People with GAD often worry about worrying. The physical component (tension, fatigue, sleep problems) and the loss of control over the worry are what separate it from ordinary stress.
Do you treat anxiety in children and teenagers?
Yes. Our child and adolescent providers treat GAD in young people, where it often shows up as perfectionism, constant reassurance-seeking, stomachaches, headaches and school avoidance rather than stated worry. CBT is first-line, and when medication is needed, sertraline and fluoxetine have the best evidence in this age group and are started at low doses. Parents are involved in the treatment plan, and we coordinate with schools on accommodations when anxiety is affecting attendance or performance.
