For example, a fairly standard course of narrowband UV light treatments for psoriasis could require three visits per week to a medical office for six to 12 weeks, while there are biologics that, once started, require as few as four injections per year. Other patients take pills one day a week for their psoriasis and psoriatic arthritis, while still others take a different treatment pill twice daily.
Other convenience factors could include that certain treatments are not compatible with consumption of alcohol; and that certain frequent travelers might find their schedules not compatible with certain treatment regimens.
