Hydrocortisone and Adrenal Crisis in Dental Practice

Generic name: Hydrocortisone

German term: Hydrocortison

Drug class: Short-acting glucocorticoid corticosteroid with mineralocorticoid activity at stress doses

Dental role: Emergency replacement steroid for suspected adrenal crisis and stress-dose planning in patients with adrenal insufficiency or steroid-induced adrenal suppression

Key point: Hydrocortisone is not a routine dental anti-inflammatory. In dental practice it is mainly important because adrenal crisis can be life-threatening and requires urgent emergency treatment.

This article is for dental education only. Suspected adrenal crisis is a medical emergency. Dental teams should call emergency medical services, follow local emergency protocols, support airway, breathing and circulation, and administer or assist with emergency hydrocortisone only if trained and permitted by local rules. Do not delay emergency care while trying to complete dental treatment.

Adrenal crisis is an acute life-threatening cortisol deficiency. It can occur in patients with primary adrenal insufficiency, secondary adrenal insufficiency, congenital adrenal hyperplasia, pituitary disease, or adrenal suppression from long-term systemic corticosteroid therapy.

Dental stress, pain, infection, surgery, vomiting, missed steroid doses, or severe anxiety can increase cortisol demand. If the patient cannot produce or absorb enough cortisol, collapse, hypotension, hypoglycemia, vomiting, confusion, or shock may develop.

The key clinical principle is: identify risk before treatment, prevent stress where possible, and act immediately if adrenal crisis is suspected.

• Best dental use: emergency preparedness and stress-dose planning, not routine pain control
• High-risk patients: Addison disease, adrenal insufficiency, pituitary disease, congenital adrenal hyperplasia, previous adrenal crisis, or long-term systemic steroid use
• Main danger: adrenal crisis may look like syncope at first but can progress to shock
• Main drug: hydrocortisone is the preferred emergency glucocorticoid for adrenal crisis
• Clinical priority: check steroid card, emergency kit, usual steroid dose, procedure stress level, and medical plan before invasive care

Cortisol helps maintain blood pressure, glucose balance, vascular response, and the body response to stress. During surgery, infection, severe pain, trauma, or emotional stress, the body normally increases cortisol production.

• Primary adrenal insufficiency: adrenal glands cannot produce enough cortisol.
• Secondary adrenal insufficiency: pituitary or hypothalamic signaling is inadequate.
• Steroid-induced adrenal suppression: long-term systemic corticosteroids suppress the hypothalamic-pituitary-adrenal axis.
• Dental relevance: invasive procedures, infection, pain, and anxiety may increase steroid needs.
• Important: patients should not stop chronic steroids suddenly before dental treatment.

Adrenal crisis can present with non-specific symptoms. In the dental chair, do not assume every collapse is simple vasovagal syncope, especially in a known steroid-dependent patient.

• Severe weakness, dizziness, confusion, or collapse
• Low blood pressure, shock, pale or clammy appearance
• Nausea, vomiting, abdominal pain, or inability to keep oral steroids down
• Hypoglycemia symptoms: sweating, tremor, altered consciousness, seizure-like presentation
• Fever, infection, or recent illness in an adrenal-insufficient patient
• Severe dental infection or surgical stress with worsening systemic symptoms
• History of Addison disease, adrenal insufficiency, pituitary disease, or emergency steroid card

1. Stop dental treatment immediately.
2. Call emergency medical services.
3. Assess airway, breathing, circulation, consciousness, and vital signs.
4. Place the patient supine if tolerated and manage shock position according to local protocol.
5. Give high-flow oxygen if available and indicated.
6. Check blood glucose if equipment and training are available; treat hypoglycemia according to local emergency protocol.
7. Administer or assist with emergency hydrocortisone if trained, authorised, and available; many adult emergency protocols use 100 mg hydrocortisone IM or IV initially.
8. Continue monitoring until emergency services take over.
9. Document the event, symptoms, timing, medications, actions, and handover details.

• Ask specifically about Addison disease, adrenal insufficiency, pituitary disease, previous adrenal crisis, and long-term steroid use.
• Ask whether the patient carries a steroid emergency card, medical alert bracelet, or hydrocortisone injection kit.
• Confirm the usual steroid dose and whether the patient has taken it on the day of treatment.
• For invasive procedures, ask whether the patient has a written stress-dose plan from their physician or endocrinologist.
• Plan stressful procedures rather than doing unexpected invasive treatment without preparation.
• Use good local anesthesia and anxiety reduction to reduce physiologic stress.
• Consider morning appointments and shorter visits for anxious or medically complex patients.
• Postpone elective treatment if the patient is acutely unwell, vomiting, febrile, or unable to take oral steroids.

Routine examinations and simple hygiene visits often do not require extra steroid cover for many patients, but anxiety, infection, surgical stress, local anesthesia procedures, extractions, sedation, or general anesthesia can change the plan.

For dental surgery, guidance varies between countries and institutions. Some plans involve an extra oral steroid dose before minor procedures, while major surgery or anesthesia may require parenteral hydrocortisone cover.

The safest dental approach is not to invent a dose in the chair. Use the patient emergency plan, endocrinology advice, local dental medical-emergency policy, and emergency services when crisis is suspected.

• Hydrocortisone: preferred for adrenal replacement and emergency stress dosing because it resembles cortisol and has mineralocorticoid activity at higher doses.
• Prednisolone: common long-term systemic steroid; patients taking it chronically may have adrenal suppression.
• Dexamethasone: potent anti-inflammatory steroid but not ideal as emergency adrenal replacement because it has little mineralocorticoid activity.
• Key difference: postoperative anti-inflammatory steroid use and adrenal-crisis steroid replacement are different clinical problems.

• Patient has symptoms suggesting adrenal crisis or circulatory collapse.
• Patient is vomiting and cannot keep oral steroid medication down.
• Patient is acutely febrile or systemically unwell before elective dental treatment.
• Patient reports missed steroid doses and feels weak, dizzy, or unwell.
• Patient has severe dental infection with systemic involvement.
• Planned invasive procedure has no stress-dose plan for a known adrenal-insufficient patient.
• Patient has severe anxiety or dental phobia that may require additional planning.
• Emergency kit, medication history, or medical advice is unclear for a high-risk procedure.

• Diabetes: stress-dose steroids can raise blood glucose; monitor and coordinate care when needed.
• Infection: steroids do not treat infection; source control and antibiotics when indicated are separate decisions.
• NSAIDs: combined steroid and NSAID exposure may increase gastric irritation risk in susceptible patients.
• Anticoagulants: surgical bleeding management still requires normal dental anticoagulant assessment.
• Immunosuppression: long-term steroid users may have infection risk, delayed healing, osteoporosis, and fragile tissues.
• Drug history: inhaled, topical, injected, and oral steroid exposure should all be recorded, but systemic long-term use is especially relevant.

• Do not stop your prescribed steroid medication before dental treatment unless your doctor tells you to.
• Bring your steroid card, medical alert information, and emergency hydrocortisone kit if you have one.
• Tell the dental team if you have Addison disease, adrenal insufficiency, pituitary disease, previous adrenal crisis, or long-term steroid use.
• Plan extractions or surgery in advance so steroid dosing can be arranged safely.
• Tell the dentist if you are unwell, vomiting, feverish, or unable to take your steroid tablets.
• Seek urgent medical help after dental care if you develop severe weakness, vomiting, collapse, confusion, fever, or worsening infection.
• For children or complex patients, caregivers should bring the written emergency plan to the appointment.

For adrenal-insufficient patients, the safest dental appointment is planned, pain-free, low-stress, well-isolated, and supported by a clear steroid plan. Prevention is better than emergency hydrocortisone in the middle of a crisis.

• Collapse, confusion, severe weakness, or altered consciousness
• Low blood pressure, shock, pale clammy skin, or persistent dizziness
• Vomiting, abdominal pain, or inability to take oral steroids
• Hypoglycemia signs: sweating, tremor, seizure-like episode, or reduced consciousness
• Fever or systemic illness in a patient with adrenal insufficiency
• Rapidly spreading dental infection, facial swelling, trismus, dysphagia, or breathing difficulty
• Known adrenal insufficiency with missed steroid doses before or after dental surgery
• Severe postoperative deterioration after extraction or oral surgery

• Prednisolone / Prednisone
• Dexamethasone
• Adrenal Insufficiency
• Addison Disease
• Stress Dose Steroids
• Dental Medical Emergencies
• Syncope vs Adrenal Crisis
• Diabetes and Steroids
• Infection and Immunosuppression
• Medically Complex Dental Patients

Hydrocortisone is central to adrenal crisis management in dentistry. Patients with adrenal insufficiency or steroid-induced adrenal suppression may not produce enough cortisol during dental stress, surgery, infection, vomiting, anxiety, or acute illness. Dental teams should identify risk before invasive treatment, confirm the patient has taken their usual steroid dose, ask about steroid cards and emergency kits, plan stressful procedures, reduce pain and anxiety, and follow medical or endocrinology stress-dose advice. Suspected adrenal crisis requires immediate cessation of dental treatment, emergency medical services, ABC assessment, oxygen and monitoring when available, glucose management if indicated, and emergency hydrocortisone according to training and local protocol. Hydrocortisone stress dosing is different from using dexamethasone for postoperative swelling. The safest approach is prevention, preparation, early recognition, and urgent escalation.
