COMMON SIDE EFFECTS
Side effects that usually do not require medical attention (report to your doctor or healthcare professional if they continue or are bothersome):

To help avoid this side effect, make sure you drink a lot of water and eat foods with plenty of fiber. If you become constipated, talk to your doctor or pharmacist about constipation medication that is safe for you to use.
