The mainstay of treatment for TT is medical therapy.
*'''Phlebotomy''' is the backbone of therapy, treatment with [[phlebotomy]] alone associated with a longer median survival compared to the use of [[chlorambucil]] or [[radioactive]] [[phosphorous]] based on a trial conducted by [[PV study group]]. Repeated phlebotomies help in [[cytoreduction]] and reduce [[hyperviscosity]] in addition to induce a state of [[iron deficiency]] which can help retard [[red cell]] [[proliferation]]. Weekly sessions are conducted, by remove 500ml of blood until a target [[hematocrit]] of under 45% is obtained. This can lower rates of [[cardiovascular]] deaths and major [[thrombotic]] episodes in patients kept under this threshold based on a trial conducted in Italy.
 
*For [[secondary polycythemia]], [[phlebotomy]] is usually reserved for the following conditions:
**[[Chronic]] [[lung diseases]]
**[[Cyanotic]] [[heart diseases]]
**Post [[renal transplant]] patients with [[hypertension]] and [[erythrocytosis]], not responding to optimal doses of [[angiotensin-converting enzyme inhibitors]] ([[ACEIs]])/[[angiotensin receptor blockers]] ([[ARB]]) <ref name="pmid24120605">{{cite journal| author=Assi TB, Baz E| title=Current applications of therapeutic phlebotomy. | journal=Blood Transfus | year= 2014 | volume= 12 Suppl 1 | issue=  | pages= s75-83 | pmid=24120605 | doi=10.2450/2013.0299-12 | pmc=3934278 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24120605  }} </ref> <ref name="pmid30252337">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume=  | issue=  | pages=  | pmid=30252337 | doi= | pmc= | url= }} </ref>
