Starting Jakafi is a big step, and it's completely natural to have questions! Here's a breakdown of what's known about side effects, how to take it, and what others have experienced.
Common Side Effects
In clinical studies, the most frequently reported side effects included:
- Low platelet count (thrombocytopenia)
- Low red blood cell count (anemia)
- Bruising
- Dizziness
- Headache
- Diarrhea
Weight gain and increased cholesterol or triglycerides have also been reported. Your doctor should check your lipid levels around 8–12 weeks after starting treatment. How To Take It
Jakafi is a tablet taken by mouth, usually twice daily. It can be taken with or without food. Your starting dose is typically based on your platelet count, and your doctor may adjust it over time based on how your body responds.
Never stop taking it suddenly without talking to your doctor first — stopping cold turkey can cause serious withdrawal-like effects. One myMPNteam member shared that stopping abruptly led to an emergency hospital visit due to a cytokine surge. How Is It Working for Others?
Many myMPNteam members report positive results, including:
- Reduced itching, sometimes within days or weeks
- Decreased spleen size and less abdominal discomfort
- More stable blood counts and fewer phlebotomies
That said, patience is key. One myMPNteam member noted it took six months for Jakafi to really kick in. Results vary from person to person. A Few Important Tips
- Keep up with regular blood work — it helps your care team catch any changes early
- Speak up about side effects as soon as they appear
- If cost is a concern, ask about the manufacturer's copay assistance program — one myMPNteam member ended up with zero out-of-pocket costs by combining it with their insurance
Staying in close contact with your hematologist throughout treatment makes a real difference. Wishing you all the best on this next chapter! 💙
