Assessment

• Assess skin lesions before starting and periodically during therapy.

• Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of Clostridioides difficile-associated diarrhea (CDAD). May begin up to several wk following cessation of therapy.

Implementation

• May cause yellow-brown discoloration and softening of teeth and bones if administered prenatally or during early childhood. Not recommended for children under 8 yr of age or during pregnancy or lactation unless used for the treatment of anthrax.
• PO Administer once daily without regard to food. Administer full glass of water to decrease risk of esophageal irritation and ulceration.

Patient/Family Teaching

• Instruct patient to take sarecycline as directed. Advise patient to read  Patient Information  before starting therapy and with each Rx refill in case of changes.
• May cause dizziness. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.

• Instruct patient to notify health care professional immediately if rash, diarrhea, abdominal cramping, fever, or bloody stools occur and not to treat with antidiarrheals without consulting health care professionals.

• Caution patient to use sunscreen and protective clothing and minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using sarecycline to prevent photosensitivity reactions.
• Advise patient to report the signs of superinfection (black, furry overgrowth on the tongue; vaginal itching or discharge; loose or foul-smelling stools) or intracranial hypertension (IH) (headache, blurred vision, diplopia, vision loss). Women who are overweight, of childbearing age or have a history of IH are at greater risk for developing IH.
• Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
• Rep:  May cause fetal harm. May permanently turn a baby or child's teeth yellow-gray-brown during tooth development during the second and third trimesters of pregnancy, and from birth to 8 years of age. May also slow bone growth in infants and children. Advise females of reproductive potential to use a nonhormonal method of contraception and avoid breastfeeding during therapy. Advise patient to notify health care professional promptly if pregnancy is suspected. May reduce fertility in males; avoid use in males attempting to conceive a child.

Evaluation/Desired Outcomes

Reduction in inflammatory skin lesions.
