Ixazomib — Uses, Dosage, Side Effects & Safety

Drug class: Proteasome inhibitor (antineoplastic agent)

Overview

Ixazomib is a prescription medicine used to treat adults with multiple myeloma, a type of blood cancer, in combination with other medications such as lenalidomide and dexamethasone. It is typically used in patients who have received at least one prior therapy. Ixazomib works by blocking the activity of proteasomes, which are cellular complexes that break down proteins. By inhibiting proteasomes, ixazomib causes cancer cells to accumulate damaged proteins, leading to cell death and slowing the progression of multiple myeloma. Key points for patients: Ixazomib is taken by mouth, usually once a week. It is important to follow your doctor’s instructions carefully, as the medication can cause side effects and requires regular monitoring. Always inform your healthcare provider about all medicines and supplements you are taking.
