Some research suggests that your body's natural fight-or-flight response to danger is involved in panic attacks. For example, if a grizzly bear came after you, your body would react instinctively. Your heart rate and breathing would speed up as your body prepared for a life-threatening situation. Many of the same reactions occur in a panic attack. But it's unknown why a panic attack occurs when there's no obvious danger present.
Once the panic attack is over and the person has returned to a calm state, encourage them to seek help from a mental health professional at their earliest convenience, if they haven’t already. You can help them further by assisting with the search for a licensed professional, researching coping techniques online, and looking for self-help books that might be useful.
Antidepressants called selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly used as first-line treatments for anxiety. Less-commonly used — but effective — treatments for anxiety disorders are older classes of antidepressants, such as tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs).
The combination of good self-help information and working with an experienced anxiety disorder coach, counselor, or therapist is the most effective way to address anxiety disorder and its many symptoms. Until the core causes of anxiety are addressed - the underlying factors that motivate apprehensive behavior - a struggle with anxiety disorder can return again and again. Identifying and successfully addressing anxiety's underlying factors is the best way to overcome problematic anxiety.
People who have had a panic attack in certain situations may develop irrational fears, called phobias, of these situations and begin to avoid them. Eventually, the pattern of avoidance and level of anxiety about another attack may reach the point where individuals with panic disorder are unable to drive or even step out of the house. At this stage, the person is said to have panic disorder with agoraphobia.
Medication can be used to temporarily control or reduce some of the symptoms of panic disorder. However, it doesn’t treat or resolve the problem. Medication can be useful in severe cases, but it should not be the only treatment pursued. Medication is most effective when combined with other treatments, such as therapy and lifestyle changes, that address the underlying causes of panic disorder.
If medications are prescribed, several options are available. Selective serotonin reuptake inhibitors (SSRIs), selective serotonin and norepinephrine reuptake inhibitors (SSNRIs), and the benzodiazepine families of medications are considered to be effective treatment of panic disorder. SSRIs include sertraline (Zoloft), fluoxetine (Prozac), paroxetine (Paxil), citalopram (Celexa), escitalopram (Lexapro), and fluvoxamine (Luvox). SSNRIs include duloxetine (Cymbalta) and venlafaxine (Effexor). Clinical trials have shown SSRIs reduce the frequency of panic attack up to 75%-85%. SSRIs must be taken three to six weeks before they are effective in reducing panic attacks and are taken once daily.
