Generic name: fluocinolone topical [ floo-oh-SIN-oh-lone-TOP-i-kal ]
Brand names: Capex, Synalar
Drug class: Topical steroids
What is Synalar?
Synalar is a corticosteroid. It reduces the actions of chemicals in the body that cause inflammation.
Synalar is used to treat the inflammation and itching caused by a number of skin conditions such as allergic reactions, eczema, seborrhea, and psoriasis.
Synalar is available as a cream, ointment, or topical solution (liquid).
Do not use 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 skin areas treated with Synalar with a bandage or other covering unless your doctor has told you to.
Plastic film covering (such as plastic wrap) is sometimes used when treating psoriasis. Follow your doctor's instructions.
Children can absorb larger amounts of Synalar through the skin and may be more likely to have side effects. If you are treating the diaper area of a baby, do not use plastic pants or tight-fitting diapers.
Call your doctor if your symptoms do not improve, if they get worse, or if you develop signs of a skin infection.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
