Acid-Reducing Drugs Linked to Higher Migraine Risk, Study Finds
People taking acid-reducing meds face a higher risk of migraines and severe headaches compared to those who don’t, a new study warns. Published in Neurology® Clinical Practice, this research shines a spotlight on common heartburn drugs and their hidden side effects.
The Acid-Reflux Meds Under the Microscope
The study zoomed in on three major types of acid-reducing treatments:
- Proton Pump Inhibitors (PPIs) – including popular drugs like omeprazole and esomeprazole.
- Histamine H2-Receptor Antagonists (H2 Blockers) – such as cimetidine and famotidine.
- Antacid Supplements – often taken for quick relief from acid reflux symptoms.
Key Findings: Migraines Spike Among Users
Researchers surveyed 11,818 people about their use of these medications and their experience with migraines or severe headaches over the past three months. The results:
- PPI Users: 25% suffered migraines, vs 19% non-users.
- H2 Blocker Users: 25% reported severe headaches, compared to 20% who didn’t take these drugs.
- Antacid Users: 22% experienced severe headaches, slightly above the 20% rate in non-users.
Adjusting for age, sex, caffeine, and alcohol, the risk jumped further:
- PPI users face a 70% higher chance of migraines.
- H2 blocker users have a 40% increased risk.
- Antacid users see a 30% higher risk.
Experts Urge Caution, Further Research Needed
Lead researcher Dr Margaret Slavin from the University of Maryland warned, “While this study shows an association, it doesn’t prove acid-reducing drugs directly cause migraines.”
She added that previous research links long-term PPI use to dementia risks.
If you suffer migraines and regularly take these medications, it’s crucial to speak with your GP to weigh the benefits and risks.
