Ate, super importante talaga yan, please ask your OB or pharmacist directly about this bago mag-switch, ha? They know your situation best and can tell you kung okay lang ang TGP version para sa iyo specifically.
I know the price difference is real, and a few of us moms talk about this too, pero sa ganitong gamot, better safe than sorry talaga. Your doc can also help you find options na affordable but trusted. Rooting for you!
