Many cirrhotics live for years with platelet
counts in the 40,000 - 50,000 range
As I said above, Interferon NOT Ribavirin causes the platelet count to drop. By reducing the dosage of Interferon your platelet count will rise.
It is important to realize each doctor is different in what they consider a dangerous platelet count. Some are not comfortable under 30,000, other are fine until getting close to 20,000.
