Extina is a prescription medication that is commonly used to treat fungal infections of the skin, such as tinea versicolor and seborrheic dermatitis. It contains the active ingredient ketoconazole, which works by inhibiting the growth of fungi that cause these infections.

When using Extina, it is important to follow the instructions provided by your healthcare provider carefully. This medication is typically applied to the affected area once daily for a specified period of time. It is important to continue using Extina for the full course of treatment, even if symptoms improve before the medication is finished.

Like all medications, Extina may cause side effects in some individuals. Common side effects may include itching, redness, or irritation at the application site. If you experience any severe or persistent side effects while using Extina, it is important to contact your healthcare provider right away.

It is also important to inform your healthcare provider of any other medications or supplements you are taking before starting Extina, as it may interact with certain medications. Additionally, if you are pregnant, nursing, or have any underlying medical conditions, it is important to discuss the use of Extina with your healthcare provider before starting treatment.

Overall, Extina can be an effective treatment option for fungal skin infections when used as directed by a healthcare provider. If you have any questions or concerns about Extina or its use, do not hesitate to reach out to your healthcare provider for more information.
