NURSING CONSIDERATIONS
Assess:

 
Pseudomembranous colitis:
diarrhea, abdominal cramps, fever; may start up to 2 mo after treatment ends

• 
I&O ratio

• 
Age and tooth development

• 
Blood tests: PT, CBC, AST, ALT, BUN, creatinine

• 
Signs of anemia: Hct, Hgb, fatigue

 
Allergic reactions:
rash, itching, pruritus, angioedema

• 
Nausea, vomiting, diarrhea; administer antiemetic, antacids as ordered

 
Overgrowth of infection:
fever, malaise, redness, pain, swelling, drainage, perineal itching, diarrhea; changes in cough or sputum; black, furry tongue

Perform/provide:

• 
Storage in airtight, light-resistant container at room temp

Evaluate:

• 
Therapeutic response: decreased temp, absence of lesions, negative C&S

Teach patient/family:

• 
To avoid sunlight, wear protective clothing; sunscreen does not seem to decrease photosensitivity

• 
That all prescribed medication must be taken to prevent superinfection; not to use outdated product because Fanconi’s syndrome may occur

• 
To avoid taking antacids, iron, cimetidine; use 2 hr before, 6 hr after this product; absorption may be decreased

• 
That teeth discoloration, joint or muscle pain may occur
