What are the side effects of pityriasis versicolor treatment?
Like all medications, pityriasis versicolor treatment can cause side effects in some people. However, most people don’t experience any side effects, or their side effects are mild and go away within a few days.
If your side effects are bothering you, getting worse or not going away, speak to your GP.
Always take your medication exactly as directed by a doctor, read the patient information leaflet carefully before starting your medication, and ask your doctor or pharmacist if you have any questions.
