RETEVMO may cause serious side effects, including:
Liver problems: Liver problems (higher levels of liver enzymes) are common with RETEVMO and may sometimes be serious. Your doctor will do blood tests before and during treatment with RETEVMO to check for liver problems. Tell your doctor right away if you get any of the following symptoms of liver problems during treatment:
- yellowing of your skin or the white part of your eyes (jaundice)
- dark, “tea-colored” urine
- sleepiness
- bleeding or bruising
- loss of appetite
- nausea or vomiting
- pain on the upper right side of your stomach area
If you develop liver problems while taking RETEVMO, your doctor may lower your dose, stop treatment for a while, or stop treatment permanently.
High blood pressure (hypertension): High blood pressure is common with RETEVMO. It may sometimes be serious. You should check your blood pressure regularly during treatment with RETEVMO. Tell your doctor if you get any of the following symptoms during treatment:
- confusion
- headaches

Heart rhythm changes (QT prolongation) can happen. These may be serious. RETEVMO may cause very slow, very fast, or irregular heartbeats. Tell your doctor right away if you get any of the following symptoms during treatment:
- loss of consciousness
- fainting
- dizziness
- a change in the way your heart beats (heart palpitations)
Bleeding problems: RETEVMO can cause bleeding, which can be serious and may lead to death. Tell your doctor if you have any signs of bleeding during treatment, including:

Tumor lysis syndrome (TLS): TLS is caused by a fast breakdown of cancer cells. TLS can cause you to have kidney failure and the need for dialysis treatment, an abnormal heartbeat, and may sometimes lead to hospitalization. Your healthcare provider may do blood tests to check you for TLS. You should stay well hydrated during treatment with RETEVMO. Call your healthcare provider or get emergency medical help right away if you develop any of these symptoms during treatment with RETEVMO:
