My husband is on day 3 of taking Dexamethasone 2mg. tabs, age 65, and the 2nd dose for today is supposed to be at 8:30pm. He has been taking 2 tabs at breakfast and 2 tabs at dinner for the last 2 days. He started experiencing hiccups yesterday, and we re taking care of that. But in the last half hour he is having chest pains. It may have elevated his BP, and he s taken more magnesium supplements, and potassium supplements...We do have a BP machine that we can take his BP with...
