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.
There are dozens of drugs that can be prescribed to treat anxiety. Since each person responds to medication differently, there's no one drug that works perfectly for everyone. You may have to work a little with a psychiatrist to find the right medication, or the right combination of medicines, that’s most beneficial to you. The drugs that are used to treat anxiety over a long period of time are antidepressants, which affect serotonin, norepinephrine, and other neurotransmitters in the brain.
SSRIs and SNRIs are commonly used to treat depression, but they are also helpful for the symptoms of panic disorder. They may take several weeks to start working. These medications may also cause side-effects, such as headaches, nausea, or difficulty sleeping. These side effects are usually not severe for most people, especially if the dose starts off low and is increased slowly over time. Talk to your doctor about any side effects that you have.
Almost everyone has something they fear – maybe it's spiders, enclosed spaces, or heights. When we encounter these "threats," our hearts might begin to race, or our hands may become sweaty. Many fear-related disorders are treated using exposure therapy. This helps people "unlearn" a threat fear response by breaking the association between the "trigger." Imagination allows patients to immerse themselves with a triggering stimulus in a controlled way, at their own pace, which is why it could be a promising new form of treatment.
Many people experience their first panic attack due a build up of chronic stress. Anxious personalities often then become afraid of them, which further stresses the body. As fear and stress increase, so does the likelihood of a subsequent panic attack. This scenario is a common catalyst into Panic Attack Disorder: becoming afraid of the feelings and symptoms of a panic attack, which causes further panic attacks.
