Outlook

Overall, antifungal shampoos, creams and tablets are effectivein killing the yeast that causes pityriasis versicolor. However, it can take several weeks or months for your skin to return to its normal colour and, in more persistent cases, treatment may need to be repeated.

Recurrences

It's common for pityriasis versicolor to come back after treatment, particularly during the summer or during holidays to warm and humid countries. However, you can reduce this likelihood by regularly using the antifungal shampoos mentioned above.

For example, continuing to use the shampoo once every two to four weeks after the initial treatment, or once a day for a few days before going on holiday, can help to prevent pityriasis versicolor recurring. As these shampoos are available to buy from pharmacies, you dont need to see your GP for a prescription if you run out.

If you develop pityriasis versicolor again after treatment, you can try treating it yourself with antifungal shampoo, or see your GP for advice and alternative treatments.

If you have frequent and severe episodes of pityriasis versicolor, your GP may consider prescribing antifungal tablets to take a few times a month to prevent the condition reoccurring.
