A nurse is teaching a client who has been prescribed tetracycline, a tetracycline antibiotic, for acne vulgaris.
Which of these instructions should the nurse include in the teaching? (Select all that apply.)
Take the drug on an empty stomach.
Avoid dairy products while taking this drug.
Use sunscreen or avoid exposure to sunlight.
Drink plenty of fluids while taking this drug.
Report any vaginal itching or discharge.
Correct Answer : A,B,C,D
The nurse should include these instructions in the teaching because:
• Tetracycline should be taken on an empty stomach to avoid interference with absorption.
• Dairy products should be avoided while taking this drug because they contain calcium, which can form insoluble complexes with tetracycline and reduce its effectiveness.
• Sunscreen or sun avoidance should be used while taking this drug because it can cause photosensitivity, which increases the risk of sunburn and skin damage.
• Plenty of fluids should be drunk while taking this drug because it can cause nephrotoxicity, which is damage to the kidneys.
Choice E is wrong because vaginal itching or discharge is not a common side effect of tetracycline. It may indicate a superinfection, which is a secondary infection caused by the disruption of normal flora by antibiotics.
This should be reported to the health care provider as soon as possible.
