Beta Blockers, also known as beta-adrenergic blocking agents, work by blocking the neurotransmitter epinephrine (adrenaline). Blocking adrenaline slows down and reduces the force of heart muscle contraction resulting in decreased blood pressure. Beta blockers also increase the diameter of blood vessels resulting in increased blood flow. Historically, beta blockers have been prescribed to treat the somatic symptoms of anxiety (heart rate and tremors) but they are not very effective at treating the generalized anxiety, panic attacks or phobias. Lopressor and Inderal are some of the brand names with which you might be familiar.
People generally can overcome panic attacks faster if they seek help after the first one or two, says psychologist Cheryl Carmin, PhD, director of clinical psychology training at the Wexner Medical Center and a professor at Ohio State University in Columbus. When you do seek help, your doctor or therapist will ask about your symptoms and the situations in which they arise, and might also recommend additional medical testing to rule out other health concerns.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
