What Synalar is and what it is used for

Synalar is a cortisone preparation. It counteracts certain skin inflammations and itching.

Cortisone preparations for external use are divided into four classes depending on the strength: I – mild action, II – medium action, III – strong action, and IV – extra strong action. Synals belong to class III.

Synalar ointment and cream are used for the treatment of various skin diseases, eg eczema, psoriasis , and inflammation of the external auditory canal. Synalar gel is particularly suitable for use on the scalp or other hairy areas.

Fluocinolone acetonide found in Synalar may also be approved to treat other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

Warnings and precautions

Talk to your doctor before using Synalar.

Synalar should not normally be used on the face, armpits, or groin. Avoid getting Synalar in or around the eyes.

Tight dressings ( occlusion dressings ) should not be used on children or infected eczema only on adults and according to a doctor’s prescription.

Do not use more Synalar than prescribed by your doctor or for longer than prescribed. Excessive use can cause streaks in the skin or thin skin. Getting used to it can happen after a long time of use. Synalar is not normally used for the treatment of widespread psoriasis as this may worsen or side effects may occur.

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. When treating large areas of the body for a long time or when treating with cover dressings, the risk of side effects increases.

Uncommon (may affect up to 1 in 100 people): Irritation where Synalar has been applied. Long-term use or too high a dosage can cause streaks in the skin, fragile blood vessels, or thin skin. Acne- and rosacea-like rashes.

Rare (may affect up to 1 in 1,000 users): Allergic reaction to Synalar (increased itching, redness, skin irritation). Increased hair growth. Inhibition of adrenal cortex function.

During long and vigorous treatment, some of the active substances can be absorbed by the body, and side effects such as the swollen face, muscle atrophy, and edema can occur. In such cases, your doctor may decide to stop the treatment.
