- Adrenal insufficiency warning: Fluocinolone cream can cause adrenal insufficiency. With this condition, the adrenal glands don’t make enough steroid hormones. This typically occurs after you stop using this drug. Your risk of adrenal insufficiency increases if you use fluocinolone cream for a long period of time or over a large part of your body. Your doctor may stop your use of this medication if you have symptoms of this condition (see below).
- Cushing's syndrome warning: Fluocinolone cream is applied to your skin, but some of the medication can be absorbed through the skin into your bloodstream. This can cause too much steroid to collect in your body, resulting in a condition called Cushing’s syndrome. To help prevent this condition, don’t cover your skin with airtight bandages. Also, avoid long-term use of this drug, and avoid using it over large areas of skin unless directed by your doctor.
- Skin infections warning: Use of fluocinolone cream raises your risk of skin infection. If you have a current infection or develop a new bacterial or fungal infection, tell your doctor right away. Your doctor may prescribe an antibacterial or antifungal drug. If the infection does not go away, your doctor may stop your use of fluocinolone until the infection has healed.
- Skin problems warning: Long-term use of fluocinolone cream may cause thinning of the skin and nearby tissues. Ask your doctor how long it’s safe for you to use this drug.
Fluocinolone is a prescription drug. It comes in five forms: cream, ointment, solution, shampoo, and oil.
