Ice chips vs. mouth sores: simple trick may ease chemo side effect
NCT ID NCT07327476
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether sucking on ice chips during chemotherapy can prevent or reduce the severity of painful mouth sores (oral mucositis) in cancer patients. 102 adults receiving 5-fluorouracil or methotrexate will be randomly assigned to either get ice chips during infusion plus standard mouth care, or standard mouth care alone. The severity of mouth sores will be measured before and after treatment using a standard grading scale.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oral ice chips (oral cryotherapy)
- What this could lead to
- If it works, this simple, low-cost method could help prevent painful mouth sores during chemotherapy, improving comfort and quality of life.
- What could go wrong
- This is a small, early-stage trial (102 people) that hasn't started yet. The benefit may be modest or not better than standard mouth care, and results may not apply to all chemo types.
