Sayang, soalan pasal ubat ni kena tanya doctor or pharmacist kamu langsung ya, dorang je boleh bagitahu cara makan yang betul untuk kamu specifically, esp since ubat iron ni ada rules sendiri depending on your condition. Tapi I understand, nausea dari ubat iron memang common kan, a few of my mum friends complained pasal yang same! Definitely mention to your doctor that you couldn't tolerate the zincofer, so they boleh adjust either the timing, the type, or maybe suggest taking with food (though ada ubat iron yang kena on empty stomach). Jangan self-adjust the timing yourself, okay? Doctor will sort you out.
