What is an adverse reaction associated with aluminum hydroxide?

Aluminum hydroxide is commonly used as an antacid to relieve symptoms of heartburn and indigestion by neutralizing stomach acid. One of the notable adverse reactions associated with aluminum hydroxide is constipation. This occurs because aluminum compounds can disrupt normal bowel function by slowing down peristalsis, leading to reduced stool frequency and harder stools. The effect of aluminum hydroxide on bowel movements can be particularly significant if used frequently or in high doses, making constipation a prominent concern for patients undergoing treatment with this medication.

Other gastrointestinal side effects exist with different antacids; however, the primary adverse effect linked specifically to aluminum hydroxide is its propensity to cause constipation, which healthcare professionals monitor when prescribing this medication.
