IF OUR MOTHER DIED FROM TAKING THE DRUG "DIGITEK", HOW MUCH CAN WE EXPECT IN COMPENSATION FROM OUR LAWSUIT?

ABOUT A YEAR AGO OUR MOTHER INGESTED SOME PILLS THAT WERE GIVEN TO HER WITH TWICE THE AMOUNT OF THE INTENDED DOSAGE. THE PILLS WERE ADULTERATED AND IT WAS DUE TO AN PHARMACEUTICAL ERROR. HER DEATH CERTIFICATE SAID SHE DIED FROM DIGITALIS TOXICITY. SHE THOUGHT SHE WAS TAKING A CERTAIN DOSAGE OF THE PILLS BUT THE WHOLE TIME SHE WAS POISONING HER BLOODSTREAM BECAUSE THE ALREADY POTENT PILLS WAS AT LEAST TWICE THE INTENDED SIZE. HOW MUCH CAN OUR LAWSUIT WIN US???????
