Hi.. thanks for writing us. Regarding your first querry.. Montek LC has specific indications like Allergic rhinitis, Asthma , should be taken under medical supervision, generally a safer drug not having interaction with B blocker or cholesterol lowering drugs. B.P is a very dynamic component of body having relation to many other organ systems that means many hormones and metabolic processes having affect on it. We can not say very casually that fluctuation of B.P is related or not to other sickness. I think you are satisfied by my answer .. If any other querry is there I will be happy to answer Take care
