A member asked:
Can patients with polycythemia vera take folic acid and vitamin b12 supplements when deficient or will it cause clots?

Won't cause clots: I don't think that it will cause clots, but the blood count is high and B12 is usually elevated. Why take the folate (folic acid) or b12?

Yes, no clot risk: If you are deficient in Folic Acid or vitamin b12, replacement is appropriate therapy. The level of hematocrit (>55%) or hemoglobin (>17gm/dl) is correlated with clotting risk, not specific vitamins. Treatment often involves phlebotomy (removing a unit of blood) which can cause iron deficiency. If one treats with iron, it is possible to stimulate a rapid rise in these counts and cause a clot.

B12/Folate: If i understand your question correctly if a patient with pcv polycythemia vera have documented Folic Acid or B12 deficiency, then those could be replaced. However, if the levels of B12 and folate (folic acid) are normal in blood, then i would not recommend it. Thanks.

Not a problem: These won't put the person at any increased risk.
