An Addison's disease diagnosis is life-changing but manageable. The medications are inexpensive, the medical aid obligations are clear, and the main risk — adrenal crisis — is largely preventable with the right preparation. Here is the practical guidance you need.
Does My Medical Aid Have to Cover This?
Yes. Addison's disease is a CDL condition. Your scheme must fund hydrocortisone and fludrocortisone indefinitely from the CDL benefit. Adrenal crisis requiring emergency care is covered under PMB. These obligations cannot be refused or limited by the state of your medical savings account.
Register for CDL Immediately
Contact your scheme's chronic benefits department. Required: - Endocrinologist's or physician's letter confirming Addison's disease (ICD-10: E27.1) - Confirming investigations: morning cortisol (typically undetectable), ACTH stimulation test result, and/or adrenal antibody result - CDL registration form
Until you are registered, medications may be processed through your MSA. Given that hydrocortisone and fludrocortisone are lifelong medications, early registration is important. Once registered, these are CDL-protected and cannot be withheld.
The Emergency Kit: Carry It Always
Every person with Addison's disease must carry an emergency IM hydrocortisone injection kit at all times. This kit contains hydrocortisone 100mg for injection, to be used when oral medication cannot be taken — during vomiting, loss of consciousness, or when emergency services are not immediately available.
Ask your endocrinologist to: 1. Prescribe the emergency IM hydrocortisone kit 2. Provide a written emergency action plan 3. Train you and a family member or close contact on IM injection technique
Ask your scheme whether the emergency kit is covered under CDL. Some schemes fund it as part of the CDL benefit; others may classify it differently. Either way — carry it. The safety imperative outweighs any administrative cost dispute.
Sick Day Rules: Share These With Your Family
During illness, fever, or physical stress, the body's requirement for cortisol increases sharply. Addison's disease patients cannot mount this response naturally — they must increase their dose manually. The rules:
- Mild illness (cold, low-grade fever < 38°C): Double your daily hydrocortisone dose until you have recovered for 24 hours.
- Significant illness (high fever ≥ 38.5°C, vomiting, flu, significant physical injury): Triple your dose. If you vomit and cannot absorb tablets, administer the IM injection immediately and go to hospital.
- Before any surgical procedure, anaesthesia, or invasive procedure: The anaesthesiologist and surgeon must be informed of your Addison's disease. IV or IM hydrocortisone cover is mandatory perioperatively.
Write these rules on a laminated card and keep it with your medication. Share them with a trusted family member or partner who can help if you become incapacitated.
Fludrocortisone: Monitor Supply
Fludrocortisone (Florinef) has experienced intermittent supply disruptions in South Africa. Maintain a buffer stock of 2–3 months wherever possible. If your pharmacy cannot source Florinef, contact your endocrinologist immediately — do not stop fludrocortisone abruptly without medical guidance. Some specialist pharmacies can access imported fludrocortisone when local supply is disrupted.
Monitoring: Annual but Important
Once stable, Addison's disease requires annual endocrinologist review: - Electrolytes (sodium, potassium) — fludrocortisone dosing adequacy - Blood pressure (postural measurements) - Weight and general wellbeing review - Bone density (DXA scan) every 2–3 years — long-term glucocorticoid use affects bone density - Thyroid function annually — autoimmune thyroid disease coexists in approximately 20% of Addison's patients
Most of these tests are covered under CDL or the scheme's chronic disease monitoring benefit. Confirm with your scheme before your annual review.
What Triggers an Adrenal Crisis?
Understanding the triggers helps prevent them. The most common precipitants are: - Gastroenteritis (vomiting and diarrhoea) — inability to absorb oral hydrocortisone is the classic trigger - Fever above 38.5°C — increased metabolic demand not met by standard replacement dose - Running out of medication — never allow this; get repeat prescriptions early - Surgery, dental procedures, or trauma — all require perioperative stress dosing - Extreme heat and dehydration — especially relevant in the SA climate
A patient who has had one adrenal crisis typically becomes very vigilant about sick day dosing. The first crisis, however, can occur before the diagnosis is established.
Practical Tips for Living with Addison's Disease
Always carry your medication. Never travel, even for a day, without your full hydrocortisone and fludrocortisone. Carry extra supplies in your hand luggage when flying — medication should never go in checked baggage.
Inform healthcare providers. Before any GP visit, dental procedure, vaccination, or minor procedure, tell the provider you have Addison's disease. Most procedures require at least a single dose doubling on the day.
Heat, exercise, and alcohol: All can exacerbate hypotension in Addison's disease. Take extra care in hot weather (SA summer). Competitive exercise may require dose adjustment — discuss with your endocrinologist.
Carry a written medical alert card alongside your MedicAlert bracelet. This card should list your diagnosis, your current medication doses, and the instruction to administer hydrocortisone 100mg IM in an emergency.
