I was perscribed orange lactulose about a month ago to use as needed, so i put it in the refrigerator to keep it cold. I opened the bottle tonight to take a dose and found that the color had completely changed. It is now a really dark green color, is that normal and is it ok to take?
Is it normal for orange lactulose to change from the orange to a dark green?

I wouldn't throw it away, I would use it;
Under recommended storage conditions, a normal darkening of color may occur. Such darkening is characteristic of sugar solutions and does not affect therapeutic action. Prolonged exposure to temperatures above 86°F (30°C) or to direct light may cause extreme darkening and turbidity which may be pharmaceutically objectionable. If this condition develops, do not use.
Prolonged exposure to freezing temperatures may cause change to a semi-solid, too viscous to pour. Viscosity will return to normal upon warming to room temperature.
