Interactions between your drugs

Moderate

telithromycin sodium picosulfate

Applies to: telithromycin and Prepopik (citric acid/magnesium oxide/sodium picosulfate)

GENERALLY AVOID: Theoretically, use of sodium picosulfate during or following antibiotic treatment may result in a reduced laxative effect of sodium picosulfate. The proposed mechanism involves antibiotic-induced reduction of colonic bacteria that hydrolyze sodium picosulfate, a prodrug, to its active metabolite bis-(p-hydroxyphenyl)-pyridyl-2-methane (BHPM), a compound that stimulates colonic peristalsis. The clinical significance of this effect remains unknown.

MONITOR: Bowel cleansing as well as overuse of certain laxatives may cause electrolyte loss and increase the risk of torsade de pointes ventricular arrhythmia in patients treated with drugs that prolong the QT interval. Electrolyte disturbances including hypokalemia and hypomagnesemia have been reported with laxative abuse and are known risk factors for torsade de pointes associated with QT interval prolongation.

MANAGEMENT: Consider use of an alternate laxative in patients who have recently taken or are currently taking an antibiotic. If concomitant use is required, additional bowel cleansing and colonoscopy may be required. The recommended dosage and duration of treatment with sodium picosulfate should not be exceeded. In addition, patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Drug and food interactions

Moderate

sodium picosulfate food

Applies to: Prepopik (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.
