Chemotherapy is not used to treat secondary polycythemia; however, it may be used to treat the primary form.
Unlike secondary polycythemia, primary polycythemia cannot be traced to an underlying condition such as smoking, high altitude, or chronic lung disease.
For example, antihistamines can alleviate itching, and aspirin can soothe burning sensations and bone pain.

 eMedicine - Polycythemia, Secondary : Article by Emmanuel C Besa, MD
In contrast to most patients with secondary polycythemia, patients with polycythemia vera must be phlebotomized and/or treated with myelosuppressive therapy to maintain their hematocrit values at no higher than 45-47%.
In contrast, polycythemia vera is characterized by bone marrow with an inherent increased proliferative activity.
Patients with familial hemoglobinopathies with increased oxygen affinity usually have a family history of similar problems in several family members, although significant numbers of patients with congenital polycythemia have no family history of similar disorders.

Primary polycythemia, also called erythremia, or polycythemia vera, is a chronic, progressive disease, most common in middle-aged men.
In secondary polycythemia, or erythrocytosis, the proliferation of red blood cells results from the body's attempt to compensate for other conditions, such as prolonged lack of oxygen at high altitudes or chronic lung or heart insufficiency.

 Polycythemia Vera
Polycythemia vera is a rare, chronic disorder involving an overproduction of blood cells in the bone marrow (myeloproliferative).
In some cases, individuals with polycythemia vera experience itching (pruritis), especially after a hot bath.
In some cases, affected individuals may have associated conditions including high blood pressure (hypertension), the formation of blood clots (thrombosis), rupturing of and loss of blood (hemorrhaging) from certain blood vessels, and/or Budd-Chiari syndrome, a rare disorder characterized by obstruction (occlusion) of veins of the liver (hepatic veins).

 Polycythemia
The increase of relative viscosity by more than twofold has a porportionate effect on the resistance to blood flow.
Anemia, the opposite of polycythemia, is a low RBC count which drops blood viscosity and increases flow rate while putting less stress on the heart.
A rise in viscosity decreases the flow rate of the blood and forces the heart to work harder to circulate the blood through the periphery.
