Pharmacological and Parenteral Therapies QID 1060

A client is prescribed oral tetracycline. What should the nurse include in the client's education about this medication?

A:
Avoid taking tetracycline with dairy products or antacids as they can interfere with absorption.
B:
Sunscreen is not necessary while taking tetracycline.
C:
Take the medication with a glass of milk to reduce stomach upset.
D:
It is safe to take tetracycline with antacids for heartburn relief.

Explanation

Tetracycline absorption can be significantly reduced by the presence of calcium in dairy products or by antacids containing magnesium, aluminum, or calcium. Clients should be advised to take tetracycline with a full glass of water on an empty stomach and to use sunscreen as tetracycline can increase photosensitivity.
