You should take magnesium oxide by mouth and drink a full glass of water with the dose. It is important to take it as directed on the label, or as directed by your doctor.

Most people tolerate this medicine very well. It can cause mild side effects like stomach cramps or diarrhea. Sometimes, it can have a laxative effect. These effects are normal if they are mild and should go away. If these or other side effects worry you, please talk to your doctor or pharmacist. 

You should store this medicine in the original container and keep it tightly closed. Also, keep it out of the reach of children.
