triangle shape,peach color,G on one side and 25mg on other side ## Other than the fact that your pill is triangular, I did find a four-sided pill that fits your description to the 'T'. It has the letter "G" on one side and the "25mg" marking on the other. This pill is identified as Eplerenone (25 mg); which is primarily used to treat high blood pressure and chronic heart failure. Manufacturer: Greenstone Limited National Drug Code (NDC): 59762-1710 Learn More: Eplerenone Details Please post back if you have any more questions or information to add regarding that pill. I hope this helps!
