Final answer:
Aluminum hydroxide can cause constipation, while magnesium hydroxide may have a laxative effect. Antacids often combine both to balance these effects, but caution is advised for those with kidney stones or who need to monitor sodium levels.
Step-by-step explanation:
Side Effects of Aluminum Hydroxide and Magnesium Hydroxide Antacid
Antacids that contain aluminum hydroxide and magnesium hydroxide are used to treat symptoms associated with excess stomach acid. However, they can lead to side effects. Aluminum hydroxide, often under the brand names like Alu-Cap and Gaviscon, can cause constipation as it slows down gastrointestinal movements. Conversely, magnesium hydroxide, a common ingredient in products like milk of magnesia, can have a laxative effect due to its ability to attract water into the intestines.
Some formulations combine both aluminum hydroxide and magnesium hydroxide to balance their respective side effects. Nevertheless, users should be cautious, especially those prone to kidney stones or those who must monitor their sodium levels, as certain antacids can raise bodily sodium and pH levels, potentially causing other health issues.
