Steroid boost for headache nerve blocks? new study checks
NCT ID NCT05732532
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding a steroid called dexamethasone to a standard occipital nerve block (using numbing medicines) provides extra headache relief. 120 adults with various headache types received injections at the back of the head. Researchers tracked changes in headache days and severity over four weeks to see if the steroid made a difference.

- Active substance
- bupivacaine, lidocaine, dexamethasone
- What this could lead to
- If adding dexamethasone works better, it could offer longer-lasting headache relief from nerve blocks without major side effects.
- What could go wrong
- This is a small, completed trial, so results may not apply to everyone. Steroids can have side effects, and the benefit may be small or none.
