What do I do if Niaspan makes me dizzy?

Niaspan can cause you to become dizzy when getting up from sitting or lying down. If you experience dizziness, you should get up slowly and carefully to prevent a fall. Dizziness caused by Niaspan often gets better as your body adjusts to the medication over the course of several weeks. However, if dizziness becomes a persistent or troubling problem for you, you should discuss it with your doctor.
