What is Rucaparib?

Rucaparib can be used to treat fallopian tube cancer or primary peritonitis. (cancer in the membrane that lines the organs within your abdomen). Rucaparib may be used to treat these conditions if the cancer is accompanied by a specific gene (an abnormal "BRCA"). You will be tested by your doctor for this gene. Rucaparib can also be used to treat prostatic cancer that has an abnormal BRCA genetic mutation. Rucaparib can be used to treat this condition if the cancer has spread and surgery or other cancer treatments have failed or stopped working. The FDA approved Rucaparib for prostate cancer on an "accelerated basis". Some people have responded to rucaparib in clinical studies. However, further research is needed. This medication guide does not list all possible uses of rucaparib.

How to take Rucaparib?

Read all instructions or guides that accompany your medication and follow their directions exactly. Even though your physician may alter its dosage, take all prescribed doses exactly. Rucaparib can be taken either with or without food once every 12 hours, as needed. When taking Rucaparib for prostate cancer treatment, another medicine known as gonadotropin-releasing hormone or GnRH may also be given in order to inhibit production of testosterone by your testicles. GnRH works to keep these testicles from producing excess amounts. If you experience vomiting shortly after taking Rucaparib, do not take another dose until after having taken your next scheduled dosage. Your cancer treatment could be delayed depending on the results of medical tests you undergo. Storage should occur away from heat and moisture at room temperature.
