You may take this medicine with or without food. Taking it with meals may lessen the chance the drug will upset your stomach. However, do not take zinc with foods high in calcium or phosphorus such as cola drinks, grain fortified breads or cereals, milk, yogurt, cheese, or ice cream. These products may keep your body from absorbing zinc properly. Ask your healthcare provider or pharmacist if you need to take other medicines at different times from when you take this supplement.

What if I overdose?

If you or anyone else has intentionally taken too much of this medicine, call 911 or go to the emergency room right away.

If you think that you or anyone else may have taken too much of this medicine, call the poison control center. Do this even if there are no signs of discomfort or poisoning.

Be careful about taking products that contain minerals while you are taking this medicine. Iron and calcium supplements may keep your body from absorbing zinc. Zinc reduces the amount of copper in your body, which may cause problems with nerves, muscles, and bones.
