Question: Hi,the query is related to my mother who is 55 years old .From past one year she had been facing trembling hands ,oversweating and weakness before lunch.This is more common when its a late lunch and some physical activity like house hold work.Once she takes food she will relax and next day she will be fine.Today afternoon it was late lunch and same symptoms of trembling and weak hands ,oversweating .After food and few hours of relaxation she complained of pricking sensation in heart .She has no heart complaints history but due to stress she used to get chest pain so few years back cardiologist had advised to give sorbitarte 5mg whenever she feels discomfort in chest.From years we have been giving her sorbitrate 5mg whenever she feels some discomfort and she used to be fine .2 years back we got her ECG done and it was normal and recent blood test cholestrol,sugar levels also are normal.Today evening I gave sorbitrate 5mg and after 2 hours of taking that she still complains about the pricking sensation in heart.How frequently can sorbitrate 5mg can be taken?In case if the pricking sensation is there till tomorrow morning can I give her sorbitrate 5mg in morning before we visit hospital ?she had never got the need to take sorbitrate consecutively for more than 3 days with one tab per day.
