A panic attack itself is usually not physically harmful, even though it can feel intensely frightening. A racing heart, dizziness, shaking or breathlessness can make you fear that something dangerous is happening. However, symptoms alone cannot tell you whether the cause is panic or a physical health problem. New, severe or unusual symptoms need medical assessment; do not assume they are anxiety. The HSE explains why a GP may check for other possible causes.
Get urgent help when needed. In Ireland, call 112 or 999 for sudden chest pain with symptoms such as breathlessness, sweating or nausea, or pain spreading to the arms, back, neck or jaw. See the HSE chest-pain guidance. Elsewhere, use your local emergency number. This article cannot assess an emergency or rule out a medical cause.
What people mean by an anxiety attack
People use “anxiety attack” in different ways. A panic attack usually refers to a sudden surge of intense fear accompanied by physical symptoms. Having one does not, by itself, mean you have panic disorder. That diagnosis involves a pattern of recurring, unexpected attacks and needs professional assessment. The NHS overview of panic disorder explains the distinction.
If panic has already been assessed
When a clinician has assessed the symptoms as panic, follow the plan you have agreed together. The HSE suggests slow, steady breathing and reminding yourself that an attack will pass. Do not use a previous panic diagnosis to dismiss symptoms that are different, more severe or otherwise concerning.
For a practical next read, use the panic attack plan. It focuses on preparation and coping; it does not replace urgent medical assessment.
When attacks keep affecting your life
Speak with your GP if attacks recur, if you worry persistently about another one, or if fear is restricting everyday activities. Treatment can include talking therapy such as CBT. Medication decisions need to be discussed with a qualified prescriber. The HSE source above describes these options.
If medical needs have been assessed and you are looking for talking therapy, you can read about help with anxiety or the practical arrangements and fees. The appointment button below opens this site’s booking page.
