Interactions between your drugs

Moderate

haloperidol bisacodyl

Applies to: haloperidol and HalfLytely and Bisacodyl (bisacodyl / polyethylene glycol 3350 / potassium chloride / sodium bicarbonate / sodium chloride)

Haloperidol can cause an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. The risk is increased if you have low blood levels of magnesium or potassium, which can occur with bowel cleansing preparations or excessive use of medications that have a laxative effect. Do not exceed the dose and duration of use of bisacodyl recommended on the product label or prescribed by your doctor. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications. In addition, you should let your doctor know if you experience signs and symptoms of low magnesium or potassium blood level such as weakness, tiredness, drowsiness, dizziness, confusion, tingling, numbness, muscle pain, cramps, nausea, or vomiting. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

haloperidol polyethylene glycol 3350

Applies to: haloperidol and HalfLytely and Bisacodyl (bisacodyl / polyethylene glycol 3350 / potassium chloride / sodium bicarbonate / sodium chloride)

Moderate

sodium bicarbonate bisacodyl

Applies to: HalfLytely and Bisacodyl (bisacodyl / polyethylene glycol 3350 / potassium chloride / sodium bicarbonate / sodium chloride) and HalfLytely and Bisacodyl (bisacodyl / polyethylene glycol 3350 / potassium chloride / sodium bicarbonate / sodium chloride)

Using bisacodyl together with sodium bicarbonate may alter the effects of bisacodyl. Bisacodyl and sodium bicarbonate should be separated by at least one hour. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

bisacodyl polyethylene glycol 3350

Applies to: HalfLytely and Bisacodyl (bisacodyl / polyethylene glycol 3350 / potassium chloride / sodium bicarbonate / sodium chloride) and HalfLytely and Bisacodyl (bisacodyl / polyethylene glycol 3350 / potassium chloride / sodium bicarbonate / sodium chloride)

Using polyethylene glycol 3350 together with bisacodyl may increase the risk of gastrointestinal side effects such as ulcerations in the colon and ischemic colitis (an inflammatory condition caused by reduced blood flow to the colon due to narrowed or blocked blood vessels). Although these side effects are relatively rare, they may be potentially serous and life-threatening, particularly ischemic colitis. Nonetheless, certain bowel cleansing regimens given prior to a colonoscopy may require the concurrent use of a stimulant laxative such as bisacodyl in order to be fully effective. You should avoid using these medications together unless specifically recommended or prescribed by your doctor. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Moderate

haloperidol food

Applies to: haloperidol

Alcohol can increase the nervous system side effects of haloperidol such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with haloperidol. Do not use more than the recommended dose of haloperidol, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Moderate

haloperidol food

Applies to: haloperidol

Consumer information for this interaction is not currently available.

MONITOR: Smoking cessation may lead to elevated plasma concentrations and enhanced pharmacologic effects of drugs that are substrates of CYP450 1A2 (and possibly CYP450 1A1) and/or certain drugs with a narrow therapeutic index (e.g., flecainide, pentazocine). One proposed mechanism is related to the loss of CYP450 1A2 and 1A1 induction by polycyclic aromatic hydrocarbons in tobacco smoke; when smoking cessation agents are initiated and smoking stops, the metabolism of certain drugs may decrease leading to increased plasma concentrations. The mechanism by which smoking cessation affects narrow therapeutic index drugs that are not known substrates of CYP450 1A2 or 1A1 is unknown. The clinical significance of this interaction is unknown as clinical data are lacking.

MANAGEMENT: Until more information is available, caution is advisable if smoking cessation agents are used concomitantly with drugs that are substrates of CYP450 1A2 or 1A1 and/or those with a narrow therapeutic range. Patients receiving smoking cessation agents may require periodic dose adjustments and closer clinical and laboratory monitoring of medications that are substrates of CYP450 1A2 or 1A1.

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.
