How to Manage Addison's Stress Dosing for Procedures?

For people with Addison’s disease (primary adrenal insufficiency), preparing for a planned medical procedure like surgery, a colonoscopy, or dental work requires careful planning. During physical stress, a healthy body naturally produces extra cortisol. Because your adrenal glands cannot do this, you must artificially mimic this response through a process called stress dosing ^[1]. Without appropriate supplemental glucocorticoids, the physical stress of surgery or illness can precipitate a life-threatening adrenal crisis ^[2].

Because everyone’s baseline medication is different—some take hydrocortisone, others prednisone, and many take fludrocortisone for mineralocorticoid replacement—there is no single universal dose for every procedure. You must work with your endocrinologist and surgical team to create a specific, individualized written plan ^[3].

Dental Work

The level of stress dosing needed for dental procedures depends on the complexity of the work, the duration, and the type of anesthesia used.

• Minor Dental Work (Local Anesthesia): For routine procedures like cleanings or simple fillings using only local numbing, your endocrinologist may instruct you to take your normal oral dose, or take a small supplemental oral dose beforehand. Always confirm your plan with your doctor, as studies showing extra steroids aren’t needed for minor dental work often exclude patients with primary adrenal insufficiency ^[4][1].
• Major Dental Work (Extractions and Sedation): Extensive oral surgery, multiple extractions, or procedures involving deeper sedation cause greater physical stress ^[5]. These situations require a customized plan; depending on the extent of the surgery and sedation, you may need a higher oral dose or IV hydrocortisone ^[6].

Colonoscopies and Bowel Preparation

Procedures that require fasting (taking nothing by mouth or “NPO”) and bowel preparation present unique risks. Fasting alone does not mean you cannot absorb pills—often, you will be instructed to take your essential morning steroids with a small sip of clear water. However, the bowel prep requires special attention:

• Fluid and Electrolyte Shifts: The laxatives used for a colonoscopy cause significant diarrhea, which can lead to dehydration and electrolyte imbalances. This physical stress can trigger an adrenal crisis ^[7][8].
• Medication Absorption Risks: If you experience severe diarrhea or vomiting during the prep, your body may not absorb your oral medications reliably ^[9].
• The Action Plan: Your team should provide a clear plan for your glucocorticoids and fludrocortisone. If you cannot keep your oral medication down, or if you become dehydrated or hypotensive, you will need parenteral (intravenous or intramuscular) hydrocortisone and IV fluids to safely complete the prep and procedure ^[7][10].

Surgeries and Anesthesia

The required steroid regimen during surgery depends on the procedure’s invasiveness, duration, blood loss, and your hospital’s local protocols.

• Major Surgical Stress: For major surgeries, medical teams typically administer continuous or frequent IV hydrocortisone. Protocols often recommend an initial bolus (a large, fast dose) of 50 to 100 mg of IV hydrocortisone before the procedure begins ^[11].
• Continuous IV Coverage: Following the initial dose, the surgical team may administer continuous IV hydrocortisone (such as 200 mg over 24 hours) or intermittent doses (such as 50 mg every 6 hours) while severe surgical stress continues ^[12].
• Medication Coordination: The IV stress doses are meant to cover your body’s total steroid requirements during that period. You must explicitly follow your anesthesiologist’s or endocrinologist’s instructions about whether to hold or resume your normal oral pills while receiving IV steroids, so you do not accidentally over-medicate ^[1].

Recovery and Post-Procedure Care

After the procedure is over and your clinical condition has stabilized, your steroid dose will be adjusted based on your recovery.

• Transitioning and Tapering: After a brief or minor procedure, you may be able to return to your usual daily maintenance dose immediately once you can safely eat and drink ^[13]. For major surgeries, your endocrinologist will provide a step-down tapering schedule over several days ^[14]. Never alter or stop your lifelong replacement doses on your own.
• Emergency Action Plan: In the days following any procedure, you are still at risk. If you vomit, cannot keep your oral medication down, experience severe weakness, confusion, or feel faint, administer your emergency hydrocortisone injection immediately and seek urgent emergency medical care ^[15][16]. Do not wait for a routine callback from your doctor.
