Singapore: Opzelura® 15 mg/g cream (ruxolitinib phosphate): Important information regarding presence of particles in Opzelura® cream
 
Health Sciences Authority (HSA) announces that a Dear Healthcare Professional Letter has been issued by Rxilient Pte Ltd to inform healthcare professionals that small, visible crystal-like particles have been reported in Opzelura® (ruxolitinib) cream. The particles might form out of the active ingredient (ruxolitinib, as the dihydrate).

While these crystal-like particles may cause some discomfort to patients, they do not pose any significant safety risk to patients. The continued usage of the product, with the crystals like particles, over a short period of time is not expected to result in significant loss of efficacy of the treatment based on the available data. Healthcare professionals are advised to inform their patients of the possible presence of the particles and should they be present, to return the tube for a replacement.

The product is indicated for the topical short-term and non-continuous chronic treatment of mild to moderate atopic dermatitis in non-immunocompromised adult and pediatric patients 12 years of age and older whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable. It is also indicated for the topical treatment of nonsegmental vitiligo in adult and pediatric patients 12 years of age and older.
