What is Neo-Synalar?
Fluocinolone is a steroid. It reduces the actions of chemicals in the body that cause inflammation.
Neo-Synalar (for the skin) is a combination medicine used to treat infection, inflammation, and itching caused by a number of skin conditions such as allergic reactions, eczema, seborrhea, and psoriasis.
Neo-Synalar may also be used for purposes not listed in this medication guide.
Do not use Neo-Synalar in your ear canal if you have a ruptured (torn) ear drum.
Before taking this medicine
You should not use this medicine if you are allergic to fluocinolone or neomycin. Do not use this medicine in your ear canal if you have a ruptured (torn) ear drum.
To make sure Neo-Synalar is safe for you, tell your doctor if you have diabetes. Topical steroid medicines absorbed through the skin may increase the glucose (sugar) levels in your blood or urine.
FDA pregnancy category C. It is not known whether fluocinolone and neomycin will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medicine.

Children can absorb larger amounts of this medicine through the skin and may be more likely to have side effects.
How should I use Neo-Synalar?
Follow all directions on your prescription label. Do not use Neo-Synalar in larger amounts or for longer than recommended. Topical steroid medicine can be absorbed through the skin, which may cause steroid side effects throughout the body.
Do not cover treated skin areas with a bandage or other covering unless your doctor has told you to. If you are treating the diaper area of a baby, do not use plastic pants or tight-fitting diapers.
Covering the skin that is treated with fluocinolone topical can increase the amount of medicine your skin absorbs, which may lead to unwanted side effects. However, plastic film covering (such as plastic wrap or a shower cap) is sometimes used when treating psoriasis. Follow your doctor's instructions.
Wash your hands before and after using Neo-Synalar, unless you are using the medication to treat the skin on your hands.
Apply a small amount of the medicine to the affected area and rub it gently into the skin. Do not apply this medicine over a large area of skin.
Call your doctor if your symptoms do not improve, if they get worse while using this medicine.
If you use fluocinolone and neomycin long-term, you may need frequent medical tests at your doctor's office.
Store at room temperature away from moisture and heat. Keep the tube tightly closed when not in use.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
An overdose of fluocinolone and neomycin is not expected to produce life threatening symptoms. However, long term use of high steroid doses can lead to symptoms such as thinning skin, easy bruising, changes in the shape or location of body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.

If Neo-Synalar gets in your eyes, rinse with water. Do not use Neo-Synalar on broken or infected skin, or in an open wound.
