Hello the cause of most panic attacks is not clear, so treatment may be different for each person. Medication is used for prevention and/or immediate alleviation of symptoms and is usually the main line of treatment. In addition, psychotherapy such as cognitive-behavioral therapy, relaxation, and/or meditation are often used to help relax the body and relieve anxiety. If you're in the middle of a panic attack, immediate relief of anxiety symptoms can come from taking a sedative type anti-anxiety medication .These drugs are provided at least in the beginning of medical therapy, but are not for long-term use. Certain antidepressants can help prevent anxiety and reduce the frequency and severity of panic attacks, but are not used for immediate relief during an attack. Frequently used antidepressants are the selective serotonin reuptake inhibitors (SSRIs) .This group of medications is often considered the first line of treatment for panic disorders. Consult psychiatrist for further evaluation and treatment.
