Hello thanks for asking from HCM Panic attacks are nothing but severe paroxysmal anxiety that occurs in episodes and cause sense of impending doom apart from other common features of anxiety. The disorder can be treated easily if proper medicines are given. For severe anxiety attacks medicines like Propranolol, Atenolol which are beta blocker drugs are used. Some psychiatrists prefer benzodiazepines like Etizolam, Clonazepam for such attacks. SSRIs like sertraline, escitalopram are drugs approved for proper treatment. Consult a psychiatrist for prescription of these drugs. Psychological methods of treatment in form of Relaxation Exercises, Progressive Muscle Relaxation Exercise etc have excellent results in anxiety and panic attacks. Thanks, hope this helps you.
