Side Effects Of Milk Of Magnesia

Lightheadedness

Patients who take milk of magnesia on a long-term basis or at doses larger than the recommended levels could experience lightheadedness and dizziness. Patients who feel lightheaded could faint, and they are at a higher risk for falls and injuries. During an episode of lightheadedness, the patient should try to sit or lie down as soon as possible. Patients who experience this symptom while taking milk of magnesia should discontinue the use of the medicine immediately. It can be helpful for the patient to keep a journal of episodes of lightheadedness that have occurred so they can share this information with the doctor. To assess lightheadedness, doctors will perform a physical examination, and patients may need to have blood tests or imaging studies. This symptom may resolve on its own once milk of magnesia is stopped.
