Study: Antacids During Pregnancy Linked to Increase in Asthma in ChildrenNot only do they make your acid reflux problems worse, acid blockers actually sicken your unborn child. An analysis of eight different studies, including data from over 1.6 million patients, found that taking heartburn medication during pregnancy significantly increases the risk for asthma for the baby. The researchers found that proton pump inhibitors (such as Prilosec or Nexium) increase the risk of babies developing asthma by 30%; other acid blockers (like Pepcid and Tagamet) increased the risk by 46%. These are huge numbers. This is of course only the latest alarm bell to go off regarding Big Pharma’s wrong-headed answer to acid reflux and stomach problems. These drugs are the poster children of everything wrong with our current medical establishment and drug approval process.
