Hello I am Dr Ravinder Sharma. On the basis of the information provided it appears that your BP tablet is stuck up at the back of throat or nose. The common sites of lodgement can be tonsillar fossa, nasaopharynx and pyriform
sinus. This is a unusual situation and the discomfort because of the bitter tast of medication every time you swallow can be very disturbing. First thing that should be done is an endoscopic examination of nose and throat. It is a OPD procedure and if tablet can be seen stuck up at any point it can be removed. It is quite possible that this tablet will absorb with time but then if it gets displaced(due to shrinking size due to absorption) and relodged in your airway then it can be a cause of breathing difficulty or an infection in the lung because of foreign body. I hope this answers your concerns. Do let me know if you have any more concerns with regards Ravinder Sharma
