The side effect referred to above is indicated in the Patient Leaflets pertaining to the medications. Additionally I read on another patient information sheet that Amlodopine can sometimes interfere with some LFT readings notably those for bilirubin and i think the other was AST.
I have encountered outcomes with my own medical condition that seem to have some correlation with those referred to in both scenarios mentioned above and I shall be discussing it with my doctor when I can get an appointment in due course . Meantime would be glad to hear if anyone has had similar personal adverse side effect experieneces when taking these medications together?
