Right now, the low neutrophils can be remedied with
filgrastim (Neupogen, Neulasta), but nothing
is prescribed
for low platelets (whites involved in clotting) except for reducing the interferon. There is a drug (eltrombopag) that stimulates platelet formation but the FDA has not approved it to go with the HCV treament drugs, so insurance may not cover it.
It is always better to use the rescue drugs instead of reducing the peginterferon or riba, especially if you have not cleared yet.
