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 your doctor has prescribed this medication because he or she 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 (Clostridium difficile-associated diarrhea) due to resistant bacteria. This condition may occur weeks after treatment has stopped. Do not use anti-diarrhea or opioid medications if you have the following symptoms because these products may make them worse. Stop using this medication and tell your doctor right away if any of these rare but very serious side effects occur: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.
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.
