Thank you for asking your query at HCM. There is no interaction among the medicines she is taking at present and she can continue them Her low pulse rate can also be explained due to hypothyroidism
and she should get her thyroid function tests
repeated again. She should also follow the orders of the cardiologist and have the holter/ stress
tests done. Sometimes anginal pain can manifest in the form of pain associated with gastritis
and it is important that her cardiac status is evaluated.
Hoping for the best.
