Jakafi can cause serious side effects including low blood counts and infection. Some people who take Jakafi have developed certain types of non‐melanoma skin cancers. Increases in blood cholesterol levels can also occur. In patients who took another JAK inhibitor to treat rheumatoid arthritis, there was an increased risk of potentially fatal cardiovascular events like heart attack or stroke in patients with risk factors for these events who smoke now or smoked in the past, as well as an increased risk of blood clots in legs or lungs and new (secondary) cancers like lymphoma, especially in patients who smoke now or smoked in the past. The most common side effects of Jakafi for certain types of myelofibrosis and PV include: low platelet or red blood cell counts, bruising, dizziness, headache, and diarrhea. Call your doctor for medical advice about side effects.
