What IRINOTECAN ALPHAPHARM is used for
IRINOTECAN ALPHAPHARM contains the active ingredient, irinotecan hydrochloride.
It is used to treat bowel cancer which has spread to other parts of the body. Cancer, which has spread, cannot be treated by surgery alone and one of the options in this situation is treatment with an anticancer medicine, known as chemotherapy.

Alternatively, IRINOTECAN ALPHAPHARM is used alone when the cancer has not responded or has returned after initial treatment.
Your doctor may have prescribed IRINOTECAN ALPHAPHARM for another reason.
