Pharmacological Index |
|
Corticosteroid, Oral |
|
|
Use |
|
Partial replacement therapy for primary and secondary adrenocortical
insufficiency in Addison's disease; treatment of salt-losing adrenogenital
syndrome |
|
|
Pregnancy Risk
Factor |
|
C |
|
|
Contraindications |
|
Known hypersensitivity to fludrocortisone; systemic fungal
infections |
|
|
Warnings/Precautions |
|
Taper dose gradually when therapy is discontinued; use with caution with
Addison's disease, sodium retention and potassium loss |
|
|
Adverse
Reactions |
|
1% to 10%:
Central nervous system: Convulsions, headache, dizziness
Dermatologic: Acne, rash, bruising
Endocrine & metabolic: Hypokalemic alkalosis, suppression of growth,
hyperglycemia, HPA suppression
Gastrointestinal: Peptic ulcer
Neuromuscular & skeletal: Muscle weakness
Ocular: Cataracts
Miscellaneous: Diaphoresis |
|
|
Overdosage/Toxicology |
|
Symptoms of overdose include hypertension, edema, hypokalemia, excessive
weight gain. When consumed in excessive quantities, systemic hypercorticism and
adrenal suppression may occur; in those cases, discontinuation and withdrawal of
the corticosteroid should be done judiciously. |
|
|
Drug
Interactions |
|
Decreased effect:
Decreased corticosteroid effects by rifampin, barbiturates, and hydantoins
Decreased salicylate levels |
|
|
Mechanism of
Action |
|
Promotes increased reabsorption of sodium and loss of potassium from renal
distal tubules |
|
|
Pharmacodynamics/Kinetics |
|
Absorption: Rapid and complete from GI tract, partially absorbed through skin
Protein binding: 42%
Metabolism: In the liver
Half-life: Plasma: 30-35 minutes; Biological: 18-36 hours
Time to peak serum concentration: Within 1.7 hours |
|
|
Usual Dosage |
|
Oral:
Adults: 0.1-0.2 mg/day with ranges of 0.1 mg 3 times/week to 0.2 mg/day
Addison's disease: Initial: 0.1 mg/day; if transient hypertension develops,
reduce the dose to 0.05 mg/day. Preferred administration with cortisone (10-37.5
mg/day) or hydrocortisone (10-30 mg/day).
Salt-losing adrenogenital syndrome: 0.1-0.2 mg/day |
|
|
Dietary
Considerations |
|
Systemic use of mineralocorticoids/corticosteroids may require a diet with
increased potassium, vitamins A, B6, C, D, folate, calcium, zinc, and
phosphorus, and decreased sodium. With fludrocortisone a decrease in dietary
sodium is often not required as the increased retention of sodium is usually the
desired therapeutic effect. |
|
|
Monitoring
Parameters |
|
Monitor blood pressure and signs of edema when patient is on chronic therapy;
very potent mineralocorticoid with high glucocorticoid activity; monitor serum
electrolytes, serum renin activity, and blood pressure; monitor for evidence of
infection |
|
|
Mental Health: Effects
on Mental Status |
|
May cause dizziness |
|
|
Mental Health:
Effects on Psychiatric
Treatment |
|
Barbiturates and carbamazepine may decrease corticosteroid effects; useful in
the management of psychotropic-induced hypotension |
|
|
Dental Health: Local
Anesthetic/Vasoconstrictor
Precautions |
|
No information available to require special precautions |

Patient
Information |
|
Take exactly as directed. Do not take more than prescribed dose and do not
discontinue abruptly; consult prescriber. Take with or after meals. Take
once-a-day dose with food in the morning. Limit intake of caffeine or
stimulants. Maintain adequate nutrition; consult prescriber for possibility of
special dietary recommendations. If diabetic, monitor serum glucose closely and
notify prescriber of changes; this medication can alter hypoglycemic
requirements. Notify prescriber if you are experiencing higher than normal
levels of stress; medication may need adjustment. Periodic ophthalmic
examinations will be necessary with long-term use. You will be susceptible to
infection; avoid crowds or infected persons or persons with contagious diseases.
You may experience insomnia or nervousness; use caution when driving or engaging
in tasks requiring alertness until response to drug is known. Report weakness,
change in menstrual pattern, vision changes, signs of hyperglycemia, signs of
infection (eg, fever, chills, mouth sores, perianal itching, vaginal discharge),
other persistent side effects, or worsening of condition.
Pregnancy/breast-feeding precautions: Inform prescriber if you are or intend
to be pregnant. Consult prescriber if breast-feeding. |

Nursing
Implications |
|
Monitor blood pressure and signs of edema when patient is on chronic therapy;
very potent mineralocorticoid with high glucocorticoid activity; monitor serum
electrolytes, serum renin activity, and blood pressure; monitor evidence of
infection; closely monitor patients with Addison's disease and stop treatment if
a significant increase in weight or blood pressure, edema or cardiac enlargement
occurs |
