If you are in the hospital, your healthcare team will provide Jakafi for you. If you’re at home, Jakafi will come to you from a specialty or mail order pharmacy. You will not be able to pick up Jakafi at a local pharmacy.
It is important to let your local pharmacist know that you are taking Jakafi and also to tell the specialty pharmacy about any other medicines, vitamins, and supplements you are taking. That way, your pharmacists can help you avoid any possible interactions between drugs.


Be sure to watch for any new or worsening signs and symptoms and discuss them with your Transplant Team right away.
