NURSING CONSIDERATIONS
Assess:

• 
Renal studies: BUN, creatinine at least monthly during treatment, 3 mo after treatment

• 
Product blood level during treatment 12 hr after dose, toxic >400 ng/ml

• 
Hepatic studies: alk phos, AST, ALT, bilirubin; hepatotoxicity:
dark urine, jaundice, itching, light-colored stools; product should be discontinued

• 
Serum lipids, magnesium, potassium, cycloSPORINE blood concentrations

 
Encephalopathy:
impaired cognition, seizures, visual changes including blindness, loss of motor function, movement disorders and psychiatric changes; dosage reduction or discontinuation may be needed in severe cases

 
Nephrotoxicity:
6 wk after surgery, acute tubular necrosis, CyA trough level >200 ng/ml, gradual rise in creatinine (0.15 mg/dl/day), creatinine plateau <25% above baseline, intracapsular pressure <40 mm Hg

 
Signs/symptoms of encephalopathy, lymphoma

Evaluate:

• 
Therapeutic response: absence of rejection

Teach patient/family:

• 
To report fever, chills, sore throat, fatigue, since serious infections may occur; tremors, bleeding gums, increased B/P

• 
To use contraceptive measures during treatment, for 12 wk after ending therapy; to notify prescriber if pregnancy is planned or suspected

• 
To take at same time of day, every day; not to skip doses or double dose; not to use with grapefruit juice or receive vaccines; that there are many drug interactions; not to add new or discontinued products without approval of prescriber

 

Black Box Warning:

To limit UV exposure

• 
That treatment is lifelong to prevent rejection; to identify signs of rejection

• 
To report severe diarrhea because drug loss may result

• 
About the signs of nephrotoxicity: increased B/P, tremors of the hands, changes in gums, increased hair on body, face

• 
To continue with all lab work and follow-up appointments

• 
That types of products are not interchangeable

• 
Not to wash syringe/container with water, variation in dose may result
