First 40 weeks I took Ribasphere (Ribavirin Capsules) made by DSM Pharmaceuticals, Greenville, NC
The label indicates that each capsule contains Ribavirin
, USP - 200mg
For the last two weeks I started to take Ribavirin Tablets
, made by Sandoz, Princeton, NJ
Each film -coated tablet contains :Ribavirin 200 mg
Could it possibly be any difference between the two?
What does USP stand for?
Could this switch be the possible cause of my sudden drop in hemoglobin?
