Diagnosed around 11 months ago, currently on daily Aspirin and Interferon Alpha 4 times a week. My consultant has confirmed my counts are slow to stabilize but they were going in the correct direction. Had a blood test this week and some of the counts are creeping up again, I just managed to avoid a venasection (Yay!) but they have now started talking about increasing my dosage again if result don’t improve next time. After diagnoses of PV/ET, how long did it take for blood counts to stabilize?
