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?

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.
