Common Side Effects of Belumosudil

In clinical studies, some common side effects were reported in patients taking belumosudil. These included infections, fatigue or weakness, nausea, diarrhea, shortness of breath, and cough. Some patients may also experience swelling, bleeding, abdominal pain, muscle or bone pain, headache, and high blood pressure. This is not a complete list of possible side effects. If you experience any discomfort, especially if the above symptoms become severe or persistent, consult your doctor promptly. Depending on the severity of your side effects, your doctor may adjust your dosage, suspend treatment, or in rare cases, discontinue treatment permanently.

Use in Special Populations

Belumosudil may cause harm to an unborn baby, so strict contraceptive measures are essential during treatment. If you could become pregnant, your doctor will perform a pregnancy test before starting therapy. Women of childbearing potential must use effective contraception during treatment and for 1 week after the last dose. Similarly, men with female partners of childbearing potential should also use effective contraception during the same period. If you become pregnant or suspect you may be pregnant while taking this medication, inform your doctor immediately. In addition, as it is unknown whether belumosudil passes into breast milk, breastfeeding should be avoided during treatment and for 1 week after the last administration.

Effects on Fertility and Monitoring Requirements

Belumosudil may affect fertility in both males and females. If you have concerns about this, a detailed discussion with your healthcare provider prior to treatment is recommended. To ensure safe use, your doctor will conduct necessary monitoring throughout your treatment. Importantly, your healthcare provider will perform blood tests at least monthly to monitor your liver function. Regular monitoring helps detect potential problems early and intervene, ensuring safe and continuous treatment. Be sure to follow all monitoring instructions from your doctor and report any physical changes proactively.
