A nurse caring for a client receiving doxycycline for the treatment of Lyme's Disease. Which statement below should be included in the client's teaching plan?
Regular sun exposure is needed to maximize drug efficacy
Avoid water while taking this medication
Take this medication with antacids to relieve gastrointestinal symptoms
Avoid dairy products when taking this medication
The Correct Answer is D
A. Regular sun exposure is needed to maximize drug efficacy: This is incorrect; in fact, doxycycline can cause photosensitivity, and sun exposure should be minimized.
B. Avoid water while taking this medication: Water should be taken with doxycycline to help prevent esophageal irritation.
C. Take this medication with antacids to relieve gastrointestinal symptoms: Antacids can also interfere with doxycycline absorption, so they should be avoided.
D. Avoid dairy products when taking this medication: Dairy products can bind to doxycycline and reduce its absorption in the gastrointestinal tract, which decreases its effectiveness. The client should avoid dairy when taking the medication.
