Treatment for Addison's disease involves replacing the missing cortisol (usually in the form of [[hydrocortisone]] tablets) in a dosing regimen that mimics the physiological concentrations of cortisol. Treatment must usually be continued for life. In addition, many patients require [[fludrocortisone]] as replacement for the missing aldosterone. Caution must be exercised when the person with Addison's disease becomes unwell, has [[surgery]] or becomes [[pregnant]]. Medication may need to be increased during times of stress, infection, or injury.
*Acute management ( Addison's crisis)
*Chronic management 
===Acute management ===
The main stay of treatment includes [[Corticosteroids|glucocorticosteroids]] and supportive therapy.
====Goals====
*Normalization of [[blood pressure]] and volume status.
*Supplementation of adequate [[glucocorticoids]] plus [[mineralocorticoid]].
*When [[arrhythmias]] occur, or when [[potassium]] levels exceed 6.5 mmol/l, emergency lowering of potassium levels is mandated. Several agents are used to lowering [[potassium]] levels. The choice depends on the degree and cause of the [[hyperkalemia]] and other aspects of the patient's condition.


===Addisonian crisis===
====Supportive therapy====
Treatment for an acute attack, an Addisonian crisis, usually involves intravenous (into blood veins) injections of:
*Maintain [[airway]], [[breathing]], and [[circulation]], and refer immediately to tertiary care center for intravenous [[corticosteroids]].
* Cortisone ([[cortisol]])
*If the patient has pre filled syringes (emergency kit) and presents with Addisonian crisis while far from a hospital, an [[intramuscular]] injection should be given and the patient transferred to the nearest emergency room for intravenous [[normal saline]] and [[Hydrocortisone|intravenous hydrocortisone]].
* Saline solution (basically a salt water, same clear [[Intravenous therapy#Infusion equipment|IV bag]] as used to treat dehydration)
*[[Normal saline]] 0.9% or 5% [[dextrose]] in [[normal saline]] should be administered to correct [[hypotension]] and [[dehydration]].
* [[Glucose]]
*It is usually necessary to administer 1 L rapidly and a further 2 to 4 L over the first 24 hours, to correct [[hypotension]].
*Careful monitoring of blood pressure, fluid status, and serum [[sodium]] and [[potassium]] levels should be maintained.


=== Pregnancy ===
===Pharmacotherapy===
Many women with Addison's have given birth successfully and without complication, both through natural labor and through cesarean delivery. Both of these methods will require different preventative measures relating to Addison's medications and dosages. Thorough communication with one's primary care physician is the best course of action. Occasionally, oral intake of medications will cause debilitating nausea and vomiting, and thus the woman may be switched to injected medications until delivery. <ref>{{cite web |url=http://www.seekwellness.com/conditions/addisons.htm#pregnancy |title=addison's disease |format= |work=}}</ref>
*[[Dexamethasone]] should be given to patients with suspected Addisonian crisis prior to any laboratory measurements.
Addison's treatments are generally considered safe for the baby during pregnancy.
*Intravenous [[hydrocortisone]] is used to treat Addisonian crisis following [[dexamethasone]].
*In addition, [[fludrocortisone]] is needed for [[mineralocorticoid]] replacement.
====Adult====
:*Preferred regimen (1): [[Dexamethasone]] IV 2-8 mg/dose q12h followed by an oral 0.5 mg maintenance dose.
:*Preferred regimen (1): [[Hydrocortisone]] 100 mg bolus immediately; followed by either 100 mg q8h '''(or)''' 300 mg q24 by continuous infusion for 2 to 3 days; then 100 to 150 mg q24h and taper to 75 mg/d before switching to oral [[maintenance dose]]
:**Note: [[Maintenance dose]] 10 mg in the morning, 5 mg around noon, and 5 mg in the afternoon '''(or)''' 10 to 15 mg in the morning and 5 to 10 mg in the afternoon.
====Pediatric====
:* Preferred regimen (1): [[Hydrocortisone]] 1 to 2 mg/kg/dose bolus immediately; followed by 25 to 150 mg/d, given in divided doses every 6 to 8 hours (in infants and young children)or150 to 250 mg/d given in divided doses every 6 to 8 hours (in older children).
===Management of Hyperkalemia===
* [[Calcium]] supplementation ([[calcium gluconate]] 10% (10ml), preferably through a [[central venous catheter]] as the [[calcium]] may cause [[phlebitis]]) does not lower [[potassium]] but decreases [[myocardium|myocardial]] excitability, protecting against life threatening [[arrhythmias]].
* [[Insulin]] (e.g. [[intravenous injection]] of 10-15u of (short acting) [[insulin]] (e.g. Actrapid) {along with 50ml of 50% dextrose to prevent [[hypoglycemia]]}) will lead to a shift of [[potassium]] ions into cells, secondary to increased activity of the [[sodium-potassium ATPase]].
* [[Bicarbonate]] therapy (e.g. 1 [[ampule]] (45mEq) infused over 5 minutes) is effective in cases of [[metabolic acidosis]].  The [[bicarbonate]] ion will stimulate an exchange of cellular H<sup>+</sup> for Na<sup>+</sup>, thus leading to stimulation of the [[sodium-potassium ATPase]].
* [[Salbutamol]] ([[albuterol]], [[Ventolin]]<sup>®</sup>) is a β<sub>2</sub>-selective [[catecholamine]] that is administered by [[nebulizer]] (e.g. 10-20 mg).  This [[drug]] promotes movement of [[potassium]] into [[cells]], lowering the blood levels.
* [[Polystyrene sulfonate]] (Calcium Resonium, [[Kayexalate]]) is a binding resin that binds [[potassium]] within the [[Intestines|intestine]] and removes it from the [[body]] by [[defecation]]. [[Calcium]] Resonium (15g three times a day in water) can be given by [[mouth]]. [[Kayexalate]] can be given by [[mouth]] or as an [[enema]]. In both cases, the resin absorbs [[potassium]] within the [[Intestines|intestine]] and carries it out of the body by [[defecation]]. This [[medication]] may cause [[diarrhea]].
* [[Refractory]] or severe cases may need [[dialysis]] to remove the [[potassium]] from the [[circulation]].
* Preventing recurrence of [[hyperkalemia]] typically involves reduction of [[dietary]] [[potassium]], removal of an offending [[medication]], and/or the addition of a [[diuretic]] (such as [[furosemide]] (Lasix<sup>®</sup>) or [[hydrochlorothiazide]]).
* [[Patiromer]] [[anion]] is a [[potassium]] binding ion cation exchange polymer that increases the [[gastrointestinal]] excretion of [[potassium]] (it is available in 8.4, 16.8, and 25.2 grams of powder in packets to be administered once daily).  [[Patiromer]] should not be used as an [[emergency]] treatment for life-threatening [[hyperkalemia]] because of its delayed onset of action.
 
===Chronic management===
The main stay of treatment includes [[Glucocorticosteroid|glucocorticosteroids]] and [[mineralocorticoid]]<nowiki/>s.
====Goals====
*Adequate daily supplementation of [[glucocorticoid]] and [[mineralocorticoid]] to mimic normal physiology. This should aim to maintain normal [[blood pressure]], [[blood glucose]], and fluid volume, and instill a sense of well-being in the patient
*Advise patients on [[medication]] for minor illness (febrile illness or emesis) to double or triple their usual dose of [[glucocorticoid]]. In case of severe illness, they should inject themselves with a large dose of [[glucocorticoid]] and seek immediate medical attention
*If patients are monitored to normalize [[Adrenocorticotropic hormone|ACTH]] level, they are almost invariably overtreated with [[glucocorticoid]] resulting in iatrogenic [[Cushing's syndrome|Cushing syndrome]]. Treatment monitoring is primarily based on clinical features.
*Ensure that patients are aware that they must be vigilant in maintaining their therapeutic regimen.
====Precautions====
*All patients with known Addison disease should have an emergency plan in place for [[Corticosteroid medications|corticosteroid supplementation]] (oral or intramuscular), to be implemented if significant illness occurs.
*Immediate action is needed for the signs of Addisonian crisis in a known Addison disease patient
*If the patient has pre filled syringes (emergency kit) and presents with Addisonian crisis while far from a hospital, an intramuscular injection should be given and the patient transferred to the nearest emergency room for intravenous [[normal saline]] and [[Hydrocortisone|intravenous hydrocortisone]].
*In an undiagnosed patient who requires immediate [[corticosteroid]] treatment, [[dexamethasone]] may be given as it does not interfere with [[Adrenocorticotropic hormone|ACTH]] stimulation testing.
====Pharmacotherapy====
'''Glucocorticosteroid'''
:*Preferred regimen (1): [[Cortisone]] 10 to 37.5 mg q12h [[Orally ingested|orally]] given in 2 divided [[doses]] with two-thirds of the total [[dose]] given in the morning (around 8 a.m.) and one third in the afternoon (noon to 4 p.m.)
:*Preferred regimen (2): [[Hydrocortisone]] : 15-30 mg/day orally given in 2 divided [[doses]] with two-thirds of the total [[dose]] given in the morning (around 8 a.m.) and one third in the afternoon (noon to 4 p.m.)
:*Preferred regimen (3): [[Dexamethasone]] : 0.25 to 0.75 mg orally once daily
:*Preferred regimen (4): [[Prednisone]] : 2.5 to 5 mg orally once daily
'''Mineralocorticosteroid''''
:*Preferred regimen (1): [[Fludrocortisone]] : 0.1 to 0.2 mg orally once daily
mild-to-moderate stress:
:*Alternative regimen (1): [[Cortisone]]  50-100 mg/day [[Orally ingested|orally]] given in 2 divided [[doses]] with two-thirds of the total [[dose]] given in the morning (around 8 a.m.) and one third in the afternoon (noon to 4 p.m.) for 3 days
:*Alternative regimen (2): [[Hydrocortisone]] 30-90 mg/day [[Orally ingested|orally]] given in 2 divided [[doses]] with two-thirds of the total [[dose]] given in the morning (around 8 a.m.) and one third in the afternoon (noon to 4 p.m.) for 3 days
:*Alternative regimen (3): [[Dexamethasone]] 0.50 to 2.25 mg [[Orally ingested|orally]] once daily for 3 days
:*Alternative regimen (4): [[Prednisone]]  5-15 mg [[Orally ingested|orally]] once daily for 3 days
'''Severe stress'''
:*Alternative regimen (5): [[Hydrocortisone]] sodium succinate 100 mg [[intravenously]] every 6-8 hours
===Women with decreased libido===
====Androgen replacement====
*The [[ovaries]] and the [[Adrenal gland|adrenals]] are the main source of [[androgens]] in women.
*[[Dehydroepiandrosterone|The adrenals produce dehydroepiandrosterone (DHEA) and its sulfate, which are converted peripherally to androstenedione and testosterone.]]
*Women with complaints of decreased libido or sexual well-being may be treated with [[Dehydroepiandrosterone|DHEA]] replacement.
*[[Dehydroepiandrosterone|DHEA]] should be discontinued periodically to assess these symptoms.
:*Preferred regimen (1): [[Dehydroepiandrosterone|DHEA]] 50 mg orally once daily

Overview

The mainstay of treatment for Addison disease is corticosteroid replacement, if there is persistent mineralocorticoid deficiency, it should be combined with fludrocortisone.

Medical therapy

The mainstay of treatment for Addison's disease is pharmacotherapy which is replacement of deficient hormones. Medical management of Addison's disease can be discussed under two categories:[1][2][3][4][5][6][7]

  • Acute management ( Addison's crisis)
  • Chronic management

Acute management

The main stay of treatment includes glucocorticosteroids and supportive therapy.

Goals

Supportive therapy

Pharmacotherapy

Adult

  • Preferred regimen (1): Dexamethasone IV 2-8 mg/dose q12h followed by an oral 0.5 mg maintenance dose.
  • Preferred regimen (1): Hydrocortisone 100 mg bolus immediately; followed by either 100 mg q8h (or) 300 mg q24 by continuous infusion for 2 to 3 days; then 100 to 150 mg q24h and taper to 75 mg/d before switching to oral maintenance dose
    • Note: Maintenance dose 10 mg in the morning, 5 mg around noon, and 5 mg in the afternoon (or) 10 to 15 mg in the morning and 5 to 10 mg in the afternoon.

Pediatric

  • Preferred regimen (1): Hydrocortisone 1 to 2 mg/kg/dose bolus immediately; followed by 25 to 150 mg/d, given in divided doses every 6 to 8 hours (in infants and young children)or150 to 250 mg/d given in divided doses every 6 to 8 hours (in older children).

Management of Hyperkalemia

Chronic management

The main stay of treatment includes glucocorticosteroids and mineralocorticoids.

Goals

  • Adequate daily supplementation of glucocorticoid and mineralocorticoid to mimic normal physiology. This should aim to maintain normal blood pressure, blood glucose, and fluid volume, and instill a sense of well-being in the patient
  • Advise patients on medication for minor illness (febrile illness or emesis) to double or triple their usual dose of glucocorticoid. In case of severe illness, they should inject themselves with a large dose of glucocorticoid and seek immediate medical attention
  • If patients are monitored to normalize ACTH level, they are almost invariably overtreated with glucocorticoid resulting in iatrogenic Cushing syndrome. Treatment monitoring is primarily based on clinical features.
  • Ensure that patients are aware that they must be vigilant in maintaining their therapeutic regimen.

Precautions

  • All patients with known Addison disease should have an emergency plan in place for corticosteroid supplementation (oral or intramuscular), to be implemented if significant illness occurs.
  • Immediate action is needed for the signs of Addisonian crisis in a known Addison disease patient
  • If the patient has pre filled syringes (emergency kit) and presents with Addisonian crisis while far from a hospital, an intramuscular injection should be given and the patient transferred to the nearest emergency room for intravenous normal saline and intravenous hydrocortisone.
  • In an undiagnosed patient who requires immediate corticosteroid treatment, dexamethasone may be given as it does not interfere with ACTH stimulation testing.

Pharmacotherapy

Glucocorticosteroid

  • Preferred regimen (1): Cortisone 10 to 37.5 mg q12h orally given in 2 divided doses with two-thirds of the total dose given in the morning (around 8 a.m.) and one third in the afternoon (noon to 4 p.m.)
  • Preferred regimen (2): Hydrocortisone : 15-30 mg/day orally given in 2 divided doses with two-thirds of the total dose given in the morning (around 8 a.m.) and one third in the afternoon (noon to 4 p.m.)
