Uses of Codistar DX in details

This medication is used to treat itching and pain caused by minor burns/cuts/scrapes, sunburn, insect bites, minor skin irritations, or rashes from poison ivy, poison oak, or poison sumac.

Diphenhydramine belongs to a class of drugs known as antihistamines. It works by preventing the effects of a certain natural substance (histamine) that causes itching. Calamine helps to dry the oozing and weeping caused by irritation from poisonous plants.

Use of this medication is not recommended in children younger than 2 years unless directed by the doctor.

How to use Codistar DX topical

Use this medication on the skin only. Some products may need to be shaken well before use. Follow all directions on the product package, or use as directed by your doctor. Before applying, clean the affected area with soap and water. Gently pat dry. Apply to the affected area as directed, usually 3 to 4 times a day. Wash hands immediately after use, unless the area being treated includes the hands.

Do not use on large areas of the body or apply more often than directed. Do not use on chickenpox or measles. Do not use with other products that contain diphenhydramine (e.g., allergy medication taken by mouth). Your condition will not clear faster, but side effects may be increased.

Avoid getting the product in your eyes, nose, ears, or mouth. If the medication gets in these areas, rinse the area right away with clean water.

Tell your doctor if your condition persists or worsens after 7 days of treatment. If you think you may have a serious medical problem, seek immediate medical attention.
