Patients' Knowledge and Information Needs about Isotretinoin Therapy Use in Jordan.

Background: Despite being the first-line treatment for severe or moderate acne, isotretinoin has several serious side effects that necessitate the evaluation of patients' knowledge about isotretinoin side effects and its proper use. Objective: The current study aim was to explore information needs about isotretinoin by evaluating patients' knowledge about the appropriate use of isotretinoin and its associated side effects. Methods: In addition to the sociodemographic variables, a validated online questionnaire was adopted from the literature to evaluate patients' knowledge about isotretinoin use and its potential side effects. Independent Results: The most recognized side effect of isotretinoin therapy was dryness (98.1%). The study patients showed good knowledge about isotretinoin use with a mean knowledge score of 8.1 (SD = 0.7). However, more than half of them (61.0%) mistakenly thought that isotretinoin therapy should be taken continuously for more than 6 months without stop, and some of them did not know that isotretinoin is recommended to be taken with fatty meal (24%) and sunblock (24.6%). Female gender (8.2 (SD = 0.8)) and using isotretinoin for more than 6 months (8.3 (SD = 1.2)) were significantly associated with a higher knowledge score of isotretinoin use ( Conclusions: The lack of patients' information about the potential side effects, duration of therapy, and some instructions on isotretinoin use, such as taking the medication with fatty meal and sunblock, shed the light on the necessity to prepare leaflets, educational brochures, and educational posts via social media in order to improve patients' knowledge about isotretinoin therapy and its optimal use.
