Hi.. Thanks for contacting practo for health query. I am Dr,Shanmugavadivu answering your question. Your complaint is dizziness which is not getting corrected after one week of multivitamins. May be you need to look into the problem. Dizziness in this age of female could be (1) Anaemia (2) Benign positional paroxysmal vertigo which is nothing but a 8 nerve weakness. (3) hyper or hypo tension,diabetes and high cholesterol. You need to meet a physician to have a check. Hope this helps.
