Rubraca dosage: Form, strengths, how to use, and more

Rubraca (rucaparib) is a prescription drug that’s used to treat certain types of ovarian and prostate cancers. The drug comes as an oral tablet that you usually take twice daily.

Rubraca is used to treat certain types of recurrent (returning) ovarian cancer in adults with a BRCA gene mutation. (A mutation is a change.) Specifically:

  • Rubraca treats certain types of epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer. (The peritoneum lines the walls of the abdomen.)
  • For these uses, Rubraca is prescribed as maintenance (ongoing) treatment after the cancer has partially or completely responded to platinum-based chemotherapy.

Note: Fallopian tube and peritoneal cancers are similar to ovarian cancer. Because their treatments also are similar, this article will refer to all of these cancers as ovarian cancer.

Rubraca is also used to treat certain types of cancer de la prostate in adults who have a BRCA gene mutation. Specifically:

The active ingredient in Rubraca is rucaparib. (An active ingredient is what makes a drug work.) Rubraca belongs to a group of drugs called poly ADP-ribose polymerase inhibitors (PARP inhibitors).
