Darolutamide can cause fluid retention, but the provided evidence does not specifically mention volume overload as a common side effect. However, as an androgen receptor inhibitor, darolutamide may affect sodium and water retention mechanisms in the body, potentially leading to fluid retention in some patients. The typical dosage is 600 mg (two 300 mg tablets) taken twice daily with food 1. Patients taking darolutamide should monitor for signs of fluid retention, including weight gain, swelling in the extremities, shortness of breath, and increased blood pressure. This is particularly important for patients with pre-existing cardiovascular conditions, kidney disease, or those taking medications that may cause fluid retention 2. If signs of fluid retention develop, patients should contact their healthcare provider promptly as dose adjustment or additional medications like diuretics may be necessary. Regular monitoring of weight, blood pressure, and electrolytes is recommended during darolutamide treatment. It's essential to note that the most recent and highest-quality study, the ARASENS trial 3, does not specifically mention volume overload as a common side effect, but it does report similar adverse event profiles between the darolutamide and placebo groups. Therefore, while darolutamide may cause fluid retention, the evidence does not strongly support a significant risk of volume overload. However, as with any medication, patients should be closely monitored for potential side effects, and healthcare providers should be vigilant in managing any adverse reactions that may occur. In the context of real-life clinical medicine, it's crucial to prioritize caution and carefully monitor patients for signs of fluid retention or volume overload, especially those with underlying health conditions that may increase their risk. By doing so, healthcare providers can minimize potential complications and ensure the best possible outcomes for patients taking darolutamide. Key points to consider when prescribing darolutamide include:
- Monitoring for signs of fluid retention, such as weight gain, swelling, and shortness of breath
- Regular monitoring of weight, blood pressure, and electrolytes
- Dose adjustment or additional medications may be necessary if signs of fluid retention develop
- Patients with pre-existing cardiovascular conditions, kidney disease, or those taking medications that may cause fluid retention should be particularly vigilant
- The ARASENS trial reports similar adverse event profiles between the darolutamide and placebo groups, but fluid retention is a potential side effect of androgen receptor inhibitors 3, 2.
