Potential Side Effects and Interactions of Over-the-Counter Lactulose

While generally safe, lactulose can cause some side effects. The most common is increased gas and bloating, often experienced in the first few days of use. These typically subside as your body adjusts. More severe, though less frequent, side effects include diarrhea and abdominal cramping. If you experience persistent or severe diarrhea, discontinue use and consult a doctor.

Medication Interactions

Lactulose may interact with certain medications. It can affect the absorption of some drugs, potentially reducing their effectiveness. This is particularly true for medications that require a specific pH in the gut for proper absorption. Examples include some antibiotics and certain minerals. Always inform your doctor or pharmacist about all medications, including over-the-counter drugs and supplements, you are taking before starting lactulose.

Other Considerations

Individuals with lactose intolerance may experience additional digestive discomfort when using lactulose. People with kidney problems should use caution and consult a physician before using lactulose, as it can increase blood ammonia levels. Pregnant and breastfeeding women should also seek professional advice prior to use. If you have any underlying health conditions, discuss lactulose use with your doctor.
