What should you know about olaparib and ovarian cancer?

Olaparib belongs to a group called PARP inhibitors. It interferes with a cancer cell’s ability to repair certain types of DNA damage. A specialist considers the cancer’s stage, previous treatment, response to platinum chemotherapy and genetic or tumour-test results before recommending it. Olaparib can be used alone or alongside another treatment in selected situations; the exact plan depends on the individual diagnosis and local prescribing guidance.

Treatment is taken by mouth on a schedule set by the oncology team. Common problems can include tiredness, nausea, reduced appetite, diarrhoea, headache and changes in blood counts. Blood tests help the team check bone marrow function and organ function while treatment continues. Tell the team about medicines, supplements and pregnancy plans because interactions and safety considerations can affect the decision.

Ask whether your ovarian cancer has had BRCA genetic testing and genomic tumour profiling, and what those results mean for olaparib. Keep a written list of medicines and report new symptoms early rather than changing the dose yourself. Take each dose exactly as prescribed; if vomiting occurs after a dose, ask the oncology team what to do instead of taking an extra dose. Ovarian cancer care may also involve chemotherapy, surgery or supportive care, each with a different purpose.

Contact your oncology team promptly for fever, chills, signs of infection, unusual bruising or bleeding, marked weakness, breathlessness, persistent vomiting or diarrhoea, or inability to keep fluids down. Seek urgent help for severe breathing difficulty, fainting, confusion, chest pain or bleeding that does not settle. These symptoms can have several causes, but treatment-related blood-count changes or dehydration need timely assessment.

Which test result makes olaparib suitable for me? How will you monitor my blood counts and kidneys? What should I do if I miss a dose or cannot swallow a tablet? Which symptoms should be reported the same day? How will you judge whether the treatment is helping, and what alternatives are available if it is not tolerated?
