How does this medication work? What will it do for me?
This combination product contains two medications, tretinoin and erythromycin, and is used to treat certain types of acne. Tretinoin helps acne by exfoliating the skin's outer layer, which helps to reduce the formation of blackheads, whiteheads, and other acne lesions. Erythromycin belongs to the family of medications known as antibiotics. It works by killing bacteria that cause acne. You may see improvement in your acne after 2 to 3 weeks of using this medication, with full effect after 8 to 10 weeks of treatment.

How should I use this medication?
Tretinoin - erythromycin topical should be applied once daily (preferably at bedtime) to lightly cover the areas being treated. Your doctor may suggest that you apply this medication every other day for the first few weeks of treatment. Wash your hands thoroughly before and after applying this medication.
The area of application should be thoroughly cleansed with a mild soap and water and patted dry with a soft towel. Apply a small amount on your fingertip and spread it on the skin where acne lesions appear. Use only enough medication to cover the affected areas lightly. You may feel a warm or stinging sensation briefly after applying. In the morning wash your face using a mild soap.
Keep the medication away from the corners of the nose, mouth, eyes, and mucous membranes. Avoid applying excess amounts as the medication may run into the eyes and other areas that should be avoided. Avoid areas of the skin where you have other problems such as eczema, severely inflamed skin, or open skin lesions. After you wash your skin in the morning, it is recommended that you apply a moisturizer or a moisturizer with sunscreen that will not aggravate your acne. If you experience severe inflammation you should stop using the product.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Application: Avoid contact with the eyes, eyelids, angles of the nose, mouth, easily irritated areas, or other areas where treatment is not intended. Do not apply tretinoin - erythromycin topical to severely inflamed skin or to open lesions. Do not use more of this medication than recommended by your doctor. Doing so will not speed up treatment and will irritate your skin.
Skin care: Cosmetics may be used, but thoroughly cleanse the areas to be treated before applying the medication. Try to avoid products applied to the skin that have high concentrations of alcohol, spices, or lime as they cause stinging and burning on treated skin. If possible, avoid using harsh abrasives and other skin treatments, including sunlamps, while using this medication.
Hair removal is permitted (e.g., plucking, electrolysis, depilatories), but avoid these procedures at night before applying tretinoin - erythromycin topical as they may result in skin irritation.
Permanent wave solutions, waxing preparations, and medicated soaps and shampoos can sometimes irritate skin that is not being treated with this medication. Use caution so that these products do not come into contact with skin treated with tretinoin.
Skin irritation: Some people may experience temporary skin irritation, especially in early weeks of treatment. Should excessive reactions occur and the skin becomes extremely red, swollen, and crusted, the medication should be stopped and you should contact your doctor.
An apparent worsening may develop due to the medication's effect on existing deep lesions. This is a normal part of the treatment effect. Treatment should be continued.
Sunlight exposure: Exposure to sunlight, including ultraviolet sunlamps, may cause more irritation. Therefore, avoid or minimize this type of exposure during the use of tretinoin. If you cannot avoid exposure to sunlight, use sunscreen products (minimum SPF 15) and wear protective clothing over treated areas. If you get a sunburn, stop using this medication until skin redness and peeling resolves.
Pregnancy: This medication is not recommended for use during pregnancy. Women who may become pregnant should use an effective method of birth control while they are using this medication. If you become pregnant while using this medication, stop using it and contact your doctor.
Breast-feeding: Erythromycin passes into breast milk. It is not known if tretinoin passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
