Pur-bloka contains propranolol
, which you must be taking for hypertension
Usually adverse drug reactions occur within a period of few days to 1-2 years. Still its occurrence after such a long duration cannot be ruled out just on the basis of long term ingestion.
If your doctor is suspecting pur-bloka as the culprit drug, then its better to get it substituted with some other group of antihypertensive. If you improve then later on the diagnosis can be confirmed by oral provocation test.
