You are taking levothyroxine tablets -- Levoxyl®, Synthroid®, Unithroid®, or generic levothyroxine -- and you also take a proton pump inhibitor drug or antacid, and you're not at optimal levels, and still don’t feel well.



Proton pump inhibitors (PPIs) like Prilosec, Prevacid, and Nexium and antacids that contain calcium, aluminum hydroxide and/or magnesium -- such as Tums, Gaviscon, Maalox, and Mylanta -- can interfere with absorption of your levothyroxine tablets.



If you are taking any of these medications, be sure to take them at least 4 hours apart from your levothyroxine.

You can also switch to Tirosint® or Tirosint®-SOL, which are formulated to be resistant to the negative effects of these medications.
