Why does the swelling of the face appear after taking Lorazepam or Pregabalin, which does not go away after administration of Torasemide and disappears when the medicine stops working?

Swelling of the face after taking Lorazepam or Pregabalin may be associated with an allergic reaction to these medicines. If the swelling of the face does not disappear after administration of Torasemide, it means that the swelling does not result from excessive fluid retention, but has a different cause, e.g. allergic. It is difficult to judge on the basis of such a short description. I encourage you to make an appointment with the attending physician who will adjust the treatment accordingly to the current clinical condition of the patient. If you do not have the possibility of a stationary visit, I encourage you to use teleadvice, e.g. via the portal Gdziepolek.pl: https://www.gdziepolek.pl/telekonsultacja
