Can Aleve block Syntroid absorption

[ando35]

Aleve's first inactive ingredient is magnesium and magnesium blocks the absorption of synthroid. So why isn't alleve on the interaction list with Synthroid?

Something that blocks absorption is not the same as something that interacts with Synthroid...  Ingredients that block absorption just need to be taken several hours away from the Synthroid, whereas ingredients that interact may need to be avoided completely.
