Is a hematocrit level of 53% safe for therapeutic phlebotomy?
No, a hematocrit level of 53% is above the recommended safe threshold. The goal of phlebotomy treatment in PV is to maintain hematocrit levels below 45%. At 53%, phlebotomy treatment would likely be recommended to reduce this elevated level. When hematocrit levels are high (typically 55-60% or higher), doctors usually begin phlebotomy treatment.

• Dizziness
• Ringing in the ears
The procedure is considered safe with minimal side effects and is the standard first-line treatment for managing PV.
