OBJECTIVE: To compare the effectiveness of two drugs, polyethylene glycol 4000 without electrolytes and magnesium hydroxide, in the treatment of chronic functional constipation in children. METHODS: Thirty-eight children were randomly assigned to either of two groups, polyethylene glycol 4000 without electrolytes or magnesium hydroxide. The children were followed through periodic appointments until they reached 6 months of treatment. In each medical appointment the following aspects were evaluated: stool consistency, frequency of bowel movements, fecal incontinence, abdominal pain, straining and acceptance of the drugs. RESULTS: Seventeen children made use of polyethylene glycol and twenty-one received magnesium hydroxide. All variables analyzed improved for both groups, with no statistically significant differences. All children accepted polyethylene glycol, while 42.9% refused magnesium hydroxide. CONCLUSION: The two laxatives showed no difference in effectiveness for the treatment of constipation. However, due to its better acceptance, because it is odorless and tasteless, polyethylene glycol proved to be a better option for treating chronic functional constipation.
