Apply small amount to cover affected area completely. Avoid the use of occlusive wrappings or dressings unless directed by physician or other health care professional.
Patient/Family Teaching⬆⬇
Instruct patient to apply medication as directed for full course of therapy, even if feeling better. Emphasize the importance of avoiding the eyes.
Caution patient that some products may stain fabric, skin, or hair. Check label information. Fabrics stained from cream or lotion can usually be cleaned by handwashing with soap and warm water.
Patients with athlete’s foot should be taught to wear well-fitting, ventilated shoes, to wash affected areas thoroughly, and to change shoes and socks at least once a day.
Advise patient to report increased skin irritation or lack of response to therapy to health care professional.
