What is Ketoconazole?
Ketoconazole is an antifungal cream that helps treat infections like angular cheilitis, an inflammatory condition that causes painful blisters and sores on the corners of your mouth. It’s commonly caused by an overgrowth of Candida, a type of yeast that lives on your skin. While angular cheilitis can heal on its own, using antifungals can speed up recovery.
Ketoconazole is prescribed off-label for angular cheilitis, meaning it hasn’t been approved yet by the FDA for this condition. But there’s enough clinical data to show it’s safe and effective for it.
How does Ketoconazole work?
Ketoconazole works by blocking the action of an enzyme called cytochrome P450 14α-demethylase. This enzyme helps the fungi make important components it needs to grow and survive, like ergosterol This helps your immune system clear the infection more easily.<sup>[1]</sup>
Will I get side effects with Ketoconazole?
You might get side effects with Ketoconazole, but it’s not guaranteed. It’s common to experience itchiness, redness, or a burning sensation where the cream is applied. This is usually a mild reaction that goes away pretty quickly. Other side effects may include eczema or urticaria (commonly known as hives), but these are uncommon. If any of the side effects worsen or persist, let your doctor know.
What forms of Ketoconazole are there?
Ketoconazole comes in many forms, including cream, tablets, and shampoo. For angular cheilitis, the cream is typically prescribed. The other forms help treat different conditions, such as psoriasis (off-label).
What concentration does Ketoconazole cream come in?
Ketoconazole is available as a 2% cream. It’s typically applied twice a day for up to six weeks. After this, use as needed.
