I doubt they'd be required to initially insert adrenal warning onto label given it has subsequently been debunked.

Nevertheless here is the benchmark blockbuster drug label warning - Humira.

Warnings

Humira affects your immune system. Adalimumab can lower the ability of your immune system to fight infections and you may get infections more easily. Serious infections caused by viruses, fungi or bacteria have happened in people taking this medicine. Some people have died from these infections. Serious infections include tuberculosis (TB). Your doctor should test you for TB before starting and during treatment with Humira.

Tell your doctor if you have ever had:

• tuberculosis (or if anyone in your household has tuberculosis);
• a chronic infection;
• cancer;
• hepatitis B (adalimumab can cause hepatitis B to come back or get worse);
• diabetes;
• heart failure;
• any numbness or tingling, or a nerve-muscle disorder such as multiple sclerosis or Guillain-Barre syndrome;
• an allergy to latex rubber;
• if you are scheduled to have major surgery; or
• if you have recently received or are scheduled to receive any vaccine.

• Tell your doctor where you live and if you have recently traveled or plan to travel. You may be exposed to infections that are common to certain areas of the world. Humira may cause a rare type of lymphoma (cancer) of the liver, spleen, and bone marrow that can be fatal. This has occurred mainly in teenagers and young men with Crohn's disease or ulcerative colitis. However, anyone with an inflammatory autoimmune disorder may have a higher risk of lymphoma. Talk with your doctor about your own risk.
