hi, as you are 67 yrs age ,at this age giddiness after getting up from bed most commonly because of orthostatic hypotension
. Urimax can cause orthostatic hypotension in elderly , other two medication does not have that type side effects. So you better consult a physician first and check b.p. Standing and lying down positions. Till that time avoid sudden standing from lying down position , first you sit in the bed for 5 mts and after you stand.
