hi hope to guide you in a better way you are taking more drugs than you need..more anti histamine drugs itself cause cause hypotension that leads to vertigo or dizziness. just take one tablnof stemetil 1+1 for three days. you should also take one iberet folic if you are anemic too for one month. plus have one visit of ENT if symptoms still persist. also add fresh juices in your diet. take good care.
