SIDE EFFECTS: Skin redness, dryness, itching, peeling, mild burning/stinging, or worsening of acne may occur during the first 2 to 4 weeks of using the medication. These effects usually decrease with continued use. A daytime moisturizer may be helpful for very dry skin (see Notes). If any of these effects persist or worsen, tell your doctor or pharmacist promptly. Your doctor may want you to decrease how often you use the medication or stop using it. Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if any of these unlikely but serious side effects occur: blistering, crusting, severe burning/swelling of the skin. This medication may be absorbed into your bloodstream and very rarely cause a severe intestinal condition due to a bacteria called C. difficile. This condition may occur during treatment or weeks to months after treatment has stopped. Tell your doctor right away if you develop: diarrhea that doesn't stop, abdominal or stomach pain/cramping, blood/mucus in your stool. If you have these symptoms, do not use anti-diarrhea or opioid products because they may make symptoms worse. A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Wash your hands before applying this medication. Gently clean the affected skin with a mild/soapless cleanser and pat dry. Use your fingertips to apply a small amount of medication (about the size of a pea) in a thin layer over the face, usually once daily at bedtime or as directed by your doctor. Be careful to avoid the eyes and lip area. Use this medication on the skin only. Do not apply to the inner lip area or inside the nose/mouth. Do not apply to cut, scraped, sunburned, or eczema-affected skin. Avoid getting this medication in your eyes. If this occurs, flush with large amounts of water. Call your doctor if eye irritation develops. Wash your hands after using the medication to avoid accidentally getting it in your eyes. During the first few weeks of using this product, your acne might appear worse because the medication is working on pimples forming inside the skin. It may take several weeks to notice results from this medication. Use it regularly in order to get the most benefit from it. To help you remember, use it at the same time each day. Do not use a larger amount or use it more frequently than recommended. Your skin will not improve any faster, but your risk of redness, peeling, and pain will increase. Tell your doctor if your condition persists or worsens.
