I Started Taking Triamferene HCTZ Two Days Ago For Problems

I started taking Triamferene HCTZ two days ago for problems that I'm having with vertigo. Since then I have had some muscle cramps and persistance hiccups that last for hours. It seems like if I lay down for 30-40 minutes the hiccups go away but tend to return if I am active. I'm also on one diazepam pill every eight hour for the vertigo when needed
