A clinic nurse is teaching a group of teens taking tetracycline for acne. Which teaching points ...

Correct Answer: 1,2,3
Rationale 1: Food, especially milk or diary products, decreases the absorption of tetracycline.
Rationale 2: Tetracycline does cause photosensitivity that makes the skin more susceptible to sunburn.
Rationale 3: Women on oral contraceptives and tetracycline have a higher incidence of vaginal yeast infections.
Rationale 4: Tetracycline is contraindicated in pregnancy because it can cause brown stains on the baby's teeth.
Rationale 5: Tetracycline-induced diarrhea is common, but the possibility of pseudomembranous colitis must be promptly ruled out.
Global Rationale: Adverse effects of tetracycline include photosensitivity and a higher incidence of vaginal yeast infections when taken concurrently with oral contraceptives. Food decreases absorption. Diarrhea is a common adverse effect, but should be assessed for the presence of pseudomembranous colitis. Tetracycline is contraindicated in pregnancy because it can cause brown stains on the baby's teeth.
