Your experience of side effect having to take Amias medication for your High Blood Pressure is common. I am on the same medication and the side effect is itching, tiredness and light headed as though a dark cloud is hanging over me. I have been on this medication for 3 years and I find it at times my alertness is just not there. I am trying to find an alternative, maybe Beetroot juice and Cellery juice everyday could help to control HBP.
Good luck and hope you find a medication with less side effect.
