Anak, this is really something you need to ask your doctor or pharmacist directly, hindi kami dapat mag-advise on mixing medicines like that, kahit gaano kadaling tanong. Please check with your OB or doctor (or even the pharmacist sa pharmacy) bago mo i-combine yan sa gabi, okay? They'll know your full situation and can tell you what's safe for you. Better safe than sorry talaga pag dating sa meds!
