Managing Mouth Sores During Leukemia Treatment

Mouth sores (also called oral mucositis) are a common side effect of leukemia treatment. Here's what you should know about managing them:

Why Mouth Sores Happen

Chemotherapy and other systemic therapies (drugs that work throughout your body) can damage the delicate lining of your mouth, causing painful sores. This is a normal part of treatment for many leukemia patients, though not everyone experiences them.

General Management Strategies

Oral Care:

Brush your teeth gently with a soft-bristled toothbrush
Use a mild, alcohol-free mouthwash
Rinse your mouth frequently with salt water or prescribed rinses
Avoid hot foods and beverages—stick to cool or room-temperature options
Avoid spicy, acidic, or rough foods that can irritate sores

Nutrition & Hydration:

Eat soft, easy-to-swallow foods (yogurt, smoothies, applesauce, pudding, soup)
Stay well-hydrated by drinking plenty of fluids
Consider nutritional supplements if eating is difficult
A registered dietitian can help you maintain proper nutrition during treatment

Pain Management:

Ask your care team about topical numbing agents or pain medications
Avoid tobacco and alcohol, which can worsen sores
Use a straw when drinking to bypass mouth sores

When to Contact Your Care Team

Tell your healthcare team about mouth sores because they can:

Assess severity and recommend specific treatments
Prescribe medications to help with pain or healing
Monitor for infection (a serious concern with mouth sores)
Adjust your treatment plan if needed

According to the NCCN Guidelines for Patients, difficulty eating due to treatment side effects is common, and your care team can connect you with support services and specialists like a registered dietitian to help manage this challenge.
