Halometasone cream is not generally used to treat otitis externa. Halometasone cream is a corticosteroid with good anti-inflammatory, anti-allergic, and vasoconstrictor properties. It is effective for non-infectious inflammatory skin conditions for which corticosteroid therapy is effective, such as seborrheic dermatitis and contact dermatitis. Otitis externa is a diffuse inflammation of the skin of the external auditory canal, mostly caused by bacterial infection. The common causative organisms are Staphylococcus aureus, hemolytic streptococcus and so on. Therefore, Halometasone cream is generally not used in the treatment of otitis externa. If you suspect that you have otitis externa infection, you should go to the hospital in time to clarify the cause of the disease, and then follow the doctor’s instructions to use the medication.
