Interactions between your drugs

Moderate

lactulose sodium picosulfate

Applies to: lactulose and citric acid/magnesium oxide/sodium picosulfate

GENERALLY AVOID: In the treatment of portal-systemic encephalopathy, the loose stools produced by concomitant use of other laxatives may falsely suggest that adequate lactulose dosage has been achieved.

MANAGEMENT: The use of other laxatives should generally be avoided when lactulose is prescribed for portal-systemic encephalopathy, especially during the initial phase of therapy.

lactulose magnesium oxide

Applies to: lactulose and citric acid/magnesium oxide/sodium picosulfate

Preliminary data from studies in humans and rats suggest that nonabsorbable antacids given concurrently with lactulose may inhibit the reduction in colonic pH induced by lactulose. Theoretically, this may reduce the effectiveness of lactulose in the treatment of portal-systemic encephalopathy, which requires an acidic environment in the colon to promote extraction of ammonia from the blood as well as retention/elimination of ammonia as the ammonium ion. However, the clinical relevance of this interaction has not been fully elucidated.

Drug and food interactions

Moderate

sodium picosulfate food

Applies to: citric acid/magnesium oxide/sodium picosulfate

ADJUST DOSING INTERVAL: Bowel cleansing products can increase the gastrointestinal transit rate. Oral medications administered within one hour of the start of administration of the bowel cleansing solution may be flushed from the gastrointestinal tract and not properly absorbed.

MANAGEMENT: Patients should be advised that absorption of oral medications may be impaired during bowel cleansing treatment. Oral medications (e.g., anticonvulsants, oral contraceptives, antidiabetic agents, antibiotics) should not be administered during and within one hour of starting bowel cleansing treatment whenever possible. However, if concomitant use cannot be avoided, monitoring for reduced therapeutic effects may be advisable.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
