Drug Interactions between bisacodyl / sodium biphosphate / sodium phosphate and Chantix

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.

GENERALLY AVOID: Varenicline may enhance the effects of alcohol as well as alter the way an individual reacts to alcohol. During postmarketing use, some patients have reported experiencing increased intoxicating effects of alcohol while taking varenicline. In addition, some reported cases of neuropsychiatric events, including unusual and sometimes aggressive behavior directed toward oneself or others, may have been worsened by concomitant use of alcohol. These events were often accompanied by amnesia.

MANAGEMENT: Patients should be advised to limit their consumption of alcohol until they know whether varenicline affects their tolerance for alcohol, and to exercise caution driving or operating machinery until they know how quitting smoking and/or varenicline may affect them. Patients should immediately stop taking varenicline and contact their physician if they develop agitation, hostility, aggressive behavior, depressed mood, or changes in behavior or thinking that are not typical for them, or if they develop suicidal ideation or behavior.
