Despite its importance, medication tracking can be challenging. One major obstacle is the complexity of cancer treatment regimens, which can involve multiple drugs with different schedules. Patients may struggle with side effects that make it difficult to maintain their tracking routines. Cognitive impairments, whether from the cancer itself or as a side effect of treatment, can also hinder effective tracking. Additionally, older adults or those with limited technological skills may find digital tools challenging to use. Overcoming these challenges requires tailored solutions and support from healthcare providers.
