Managing breast cancer treatment side effects: CDK 4/6 inhibitors
When you have hormone receptor-positive, HER2-negative metastatic breast cancer (mBC), starting treatment with a CDK4/6 inhibitor can be daunting. Understanding potential side effects can help you manage them effectively. Common side effects from CDK 4/6 inhibitors include fatigue, low blood cell counts, nausea, vomiting, diarrhea, hair thinning or loss, and heart problems.
While these side effects can be challenging, there are strategies to help you and your care team manage them. As a starting point, the different CDK 4/6 inhibitors have different side effect profiles and you should discuss these options with your doctor.
Lifestyle adjustments: If you experience side effects from your cancer treatment, simple changes to your daily routine can make a big difference in managing side effects.
- Nausea and vomiting: Stay hydrated by sipping on clear fluids throughout the day. Eat small, frequent meals instead of large ones. Choose bland foods that are easy on your stomach. If nausea and vomiting are severe, your doctor may prescribe anti-nausea medication.
- Fatigue: While rest is important, light exercise such as walking or yoga can help combat fatigue and boost your energy levels. Prioritize sleep and listen to your body’s cues.
- Diarrhea: Stay hydrated and avoid foods that can worsen diarrhea, such as greasy or spicy foods. Your doctor may recommend over-the-counter anti-diarrheal medications as well as dietary changes.
- Hair thinning or loss: Use gentle hair care products and avoid harsh styling techniques. Consider wearing a hat or scarf to protect your scalp from the sun.
- Heart problems: Your care team will perform an EKG regularly to monitor your heart. If you experience changes in your EKG, your doctor may prescribe a different CDK 4/6 inhibitor.
Medical Interventions: If side effects become difficult to live with, your doctor may adjust your dose, switch medications, or prescribe additional medications to manage them.
- Low blood cell counts: Your doctor will monitor your blood cell counts regularly. If they become too low, you may need to temporarily pause treatment or receive medications to stimulate blood cell production.
- Other side effects: Depending on the specific side effects you experience, your doctor may recommend other interventions, such as physical therapy, dietary counseling, or psychological support. Also, since different CDK 4/6 inhibitors may have different side effect profiles, your doctor may switch the drug you’re taking.
Emotional and social support: Coping with the emotional and social impact of cancer treatment is important for your overall well-being.
- Support groups: Connecting with others who are going through similar experiences can provide emotional support, encouragement, and practical tips for managing treatment.
- Counseling: A therapist or counselor can help you cope with the emotional challenges of cancer treatment and develop healthy coping mechanisms.
- Open communication: Maintain open and honest communication with your healthcare team. Report any side effects promptly and don’t hesitate to ask for help or support.
Remember: You’re not alone in this journey. With the right support and proactive management, you can navigate the side effects of CDK 4/6 inhibitor treatment and maintain your quality of life.
