Can allergy med stop bone pain in stem cell transplants?
NCT ID NCT05421416
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether the allergy drug loratadine can prevent bone pain caused by G-CSF, a medicine used to collect stem cells for transplant. About 78 adults with lymphoma or multiple myeloma will receive either loratadine or a placebo. The goal is to see if loratadine reduces pain severity and daily-life interference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Loratadine
- What this could lead to
- If it works, this could offer a simple, over-the-counter way to prevent bone pain during stem cell collection.
- What could go wrong
- This is a small, early-phase trial with only 78 participants, so results may not apply widely. Loratadine may not reduce pain better than a placebo.
