If you have Genotype 1, you should be taking 1000mg of Riba daily, based on your weight.
You're probably anemic, that's why you feel short of breath. The Riba causes anemia.
RBC means red blood cells. Hemoglobin is a protein in red blood cells that carries oxygen. Checking the hemoglobin will tell you if you're anemic.
You SHOULD definitely get a PCR test for you viral load. Preferably the morning of your 5th shot, but BEFORE you do your shot.
I would also insist to do a CBC, especially since you are on a super high dose of Ribavirin. You are taking 24mg of Riba per kilo, which is very high and are most like anemic. You need to check your hemoglobin and I would not wait with it.
