Anak, ito talaga ay something you need to ask your doctor about directly, lalo na kung ito para sa pregnancy or any health concern kasi prescribed medicine yan at may specific reasons bakit nire-recommend nila. A few of my mum friends na nag-take nito, lagi nilang sinasabi na importante na makuha yung exact brand na prescribed ng doctor nila, hindi lang basta any brand. Ang best approach talaga is mag-consult sa OB mo or sa pharmacist kung anong other brands available dito sa Pinas na safe at same quality, they'll know kung ano ang available sa inyong area din. Trust your doc on this one, mare!
