About This Medication

# Pfizer Patient Assistance Program Patient Guide: How to Get CAMPTOSAR (irinotecan hydrochloride) at Low or No Cost CAMPTOSAR (irinotecan hydrochloride) is a chemotherapy medication used to treat certain types of cancer, such as colorectal cancer. The **Pfizer Patient Assistance Program** offers this drug at no cost to eligible uninsured or underinsured patients who meet income guidelines and other criteria.[1][5] ## About CAMPTOSAR (Irinotecan Hydrochloride) **CAMPTOSAR** is an injectable chemotherapy drug manufactured by Pfizer. It works by interfering with cancer cell growth, specifically targeting enzymes called topoisomerases that help DNA unwind during cell division. Doctors prescribe it for advanced colorectal cancer, often in combination with other treatments like 5-fluorouracil and leucovorin. It's administered in a hospital or clinic setting via intravenous infusion. Common side effects include diarrhea (which can be severe), nausea, vomiting, low blood cell counts, fatigue, and hair loss. Your doctor will monitor you closely and may prescribe supportive medications to manage these. Always follow your healthcare provider's instructions, as this guide does not replace medical advice.[5] ## Who Qualifies for the Program?
