Dosage & Administration

Standard regimens per Canadian guidelines

Arimidex, known generically as anastrozole, is primarily prescribed at a standard dosage of 1 mg once daily. Patients can take it either with or without food, but it’s best to maintain consistent timing daily to maximize effectiveness. This routine can help establish a habit and ensure that the medication works optimally for treating hormone-positive breast cancer.

Adjustments by patient type

Dosage adjustments may be necessary for various populations. For example, while elderly patients typically do not require dosage modifications, they should be monitored for a higher incidence of osteoporosis and ischemic heart disease. In patients with liver impairment, no dosage change is needed for mild cases, but severe impairment necessitates additional caution. Similarly, individuals with kidney issues usually do not need dosage adjustments unless their condition is severe.

Arimidex is often prescribed as part of a treatment plan for approximately five years in early breast cancer cases. The plan may be adjusted based on individual response, with ongoing therapy continuing as long as the medication remains beneficial.
