Liquid Paraffin, milk of magnesia (Laxative) is a commonly used laxative combination that helps relieve constipation by both softening and easing the passage of stools. Liquid paraffin acts as a lubricant, coating the stool and intestinal walls, while milk of magnesia (magnesium hydroxide) works by drawing water into the intestines, increasing stool volume and promoting bowel movement. It is usually taken orally, preferably at bedtime, as advised by the doctor. 

This medicine is effective for short-term relief of constipation, hard stools, and painful bowel movements. Common side effects include mild diarrhea, stomach cramps, nausea, and occasionally oily leakage. It should be used cautiously in pregnant women, elderly patients, and those with kidney problems, and avoided in cases of intestinal blockage. Long-term use is not recommended as it may lead to dependence or electrolyte imbalance. Drinking plenty of water and eating fiber-rich foods can improve its effectiveness and support regular bowel habits.
