Why does interferon make you feel so tired?

Interferon is known to cause fatigue as one of its side effects. This medication can lead to both physical and mental exhaustion, including body aches, drowsiness, reduced physical strength, and difficulty concentrating.

Fatigue from interferon can be challenging because it's sometimes difficult to separate whether the tiredness comes from the MPN itself, the medication, or a combination of both. The fatigue you're experiencing is a recognized side effect that many people on this treatment deal with.

If the fatigue from interferon is significantly affecting your quality of life, it's worth discussing with your hematologist. They may be able to adjust your dose or explore alternative treatment options that might cause less fatigue while still managing your MPN effectively.

In addition to medication adjustments, lifestyle approaches like good sleep habits, regular exercise, yoga, and maintaining a healthy diet may help improve your energy levels while on interferon therapy.
