Olaparib (olaparib) — Uses, Dosage, Side Effects & Safety

Drug class: PARP inhibitor (Poly (ADP-ribose) polymerase inhibitor)

Overview

Olaparib is a targeted cancer medicine used to treat certain types of cancers, including ovarian, breast, pancreatic, and prostate cancers that have specific genetic mutations (such as BRCA mutations). It is most often prescribed for patients whose cancer has returned or progressed after other treatments, or as maintenance therapy to help prevent cancer from coming back. Olaparib works by blocking an enzyme called PARP (poly (ADP-ribose) polymerase), which helps repair damaged DNA in cells. By inhibiting PARP, olaparib prevents cancer cells—especially those with BRCA mutations—from repairing themselves, leading to cell death and slowing the growth of tumors. Key points for patients: Olaparib is taken by mouth, usually twice daily. It is important to take the medication exactly as prescribed and not to skip doses. Regular blood tests are needed to monitor for side effects. Always inform your healthcare provider about all other medicines you are taking.
