SK,
oic.. that anti-itch aka flu tablet very drowsy right, i remembered once i got "feng1 mo4" when bb ard 2mth old, whole body so itchy, then the doc prescribed me this also, v effective on me leh.. he also prescribed calamine lotion for me to apply on.. though i have some reservations on taking the med then coz i was breastfeeding, but she assured me it's ok to take so i just took... cant stand the itchiness..
i think calamine lotion can get off the rack, and shd be safe for pregnant ladies bah.. remember to shake well b4 apply.. and wear long pants after that, to minimise the scratching! hee
