Abstract:
We present the case of a 38-year-old woman with no previous history of coronary heart diseases, who suffered from cluster headaches and had undergone a subcutaneous sumatriptan treatment for two years. With no previous history of underlying ischaemic heart diseases or Prinzmetal's angina or any other significant coronary diseases supported by an angiographic exam, the patient suffered from an episode of coronary vasospasm following a subcutaneous administration of sumatriptan. Therefore particular care should be placed when subcutaneous sumatriptan is administered to patients who experienced chest pain or other related symptoms after the use of the drug.
