Warning

You will be closely monitored (for example, by having blood tests) by your doctor while using this medication. Keep all medical and laboratory appointments.

Irinotecan may cause severe diarrhea, which can occur during or right after you receive this medication and/or more than 24 hours afterward. If the diarrhea starts right away, you may also have other side effects such as runny nose, increased saliva, watery eyes, sweating, stomach cramps, or flushing. If the diarrhea starts later, it could be a different type that may be persistent and can cause serious (possibly fatal) loss of too much body water (dehydration), mineral imbalance, or serious infection (sepsis).

Also tell your doctor if you have stomach/abdominal pain, extreme thirst, very dry mouth, muscle cramps/weakness, fast/slow/irregular heartbeat, fainting, dizziness, lightheadedness, or signs of infection (e.g., fever, persistent sore throat). Your doctor should prescribe other medications to treat the diarrhea and other symptoms.

Tell your doctor right away if you develop any of the following: signs of infection (fever, persistent sore throat), easy bruising/bleeding, unusual tiredness, fast/pounding heartbeat.
