• Introduction: IFNβ products and glatiramer acetate are established treatment first-line options in long-term disease-modifying therapy of multiple sclerosis (MS). These self-injectable medications are used once weekly to once daily. Injection-related issues are common patient-cited reasons for nonadherence. Autoinjectors have been shown to support long-term adherence to injectable medications. The ability to self-inject in MS patients has been associated with a reduced risk of missed injections and drug discontinuation, and a beneficial effect on patient independence.Areas covered: The recently introduced easy-to-use prefilled once-weekly pen is a safe and effective device for intramuscular (IM) IFNβ-1a application and provides a convenient method for self-injection. We reviewed the available published evidence on the characteristics of this device. The once-weekly pen facilitates self-injection and was preferred over prefilled syringes by patients in a prospective open-label, multicenter Phase IIIb trial in MS patients who had been using IM IFNβ-1a in prefilled syringes.Expert opinion: The simple and safe handling, shielded short needle, single-use disposable design and virtually painless injection by the device may contribute to adherence, quality of life and independence in patients using IM IFNβ-1a.
