How long is chemo in your body?

Chemotherapy drugs remain in your body for varying amounts of time, depending on the specific drugs used. Some drugs are eliminated quickly, while others can remain in your body for several weeks or even months. The length of time that a chemotherapy drug remains in your body can affect the side effects you experience.

For example, drugs that are eliminated quickly may cause short-term side effects such as nausea, vomiting, and hair loss. Drugs that remain in your body for a longer period of time may cause long-term side effects such as fatigue, kidney damage, and heart damage.

Your doctor will closely monitor your blood levels of chemotherapy drugs to ensure that you are receiving the correct dose and to minimize the risk of side effects.
