Possible Side Effects and Risks of Milk of Magnesia
Side effects are not common in people who take milk of magnesia. These may include vomiting, nausea, chalky taste, stomach cramps, and diarrhea. In some cases, more severe side effects may occur. Stop taking the medication and visit your doctor immediately when you have one of the following problems: lightheadedness, slower heartbeat, severe vomiting or nausea, no bowel movements, or rectal bleeding. In fact, these signs tend to happen in those who take more than the recommended dosage or longer than needed. [5]
It is important to drink a lot of water when you take milk of magnesia. This medication may draw water from other body parts and increase the risk of dehydration. In case you have diarrhea after taking a single dose, it is better to avoid this product. Some people may overdose on milk of magnesia. This would lead to some symptoms, such as no or little urination, irregular or slow heartbeat, mood change, muscle weakness, or serious diarrhea. Allergies may also happen, so make sure to check the ingredient list. Lastly, avoid the medication if you have kidney issues. [6]
