A patient is prescribed Cholestyramine to lower their cholesterol levels. Which of the following instructions should the nurse provide to the patient regarding the timing of taking this medication?
Take Cholestyramine with other medications to improve absorption
Take the powder for oral suspension in dry form
Take after meals
Take other medications at least 1 hour before or 4 hours after taking Cholestyramine
The Correct Answer is D
A. Take Cholestyramine with other medications to improve absorption: Cholestyramine binds bile acids in the intestine but can also bind and interfere with the absorption of other oral medications. Taking it with other drugs reduces their effectiveness and is not recommended.
B. Take the powder for oral suspension in dry form: Cholestyramine powder should never be taken dry as it can irritate the mouth, throat, and gastrointestinal tract. It should always be mixed with water or a non-carbonated beverage before ingestion to prevent choking or esophageal irritation.
C. Take after meals: While taking it after meals can enhance its bile acid-binding effect, this alone does not prevent drug interactions. Timing with other medications is the more critical issue to address when instructing patients.
D. Take other medications at least 1 hour before or 4 hours after taking Cholestyramine: This instruction is essential to avoid interference with the absorption of other oral medications. Cholestyramine can bind many drugs, so proper spacing is required to ensure therapeutic efficacy of concurrent medications.
