The nurse is preparing instructions for a client with a new prescription for colesevelam [Welchol]. Which of the following will the nurse include in medication teaching?
Correct answer
D
Rationale
The correct answer is D: Take at least 4 hours after other medications. Colesevelam is a bile acid sequestrant used to lower cholesterol. It can bind to other medications and interfere with their absorption. Taking it at least 4 hours after other medications ensures proper absorption of both drugs. Choice A is incorrect because diarrhea is not a common side effect of colesevelam. Choice B is incorrect because colesevelam should not be taken with a multivitamin as it can interfere with its absorption. Choice C is incorrect because the dosage of colesevelam should not be repeated every 2 to 4 hours, as it is usually taken once or twice daily with meals.
