Hello, My mom was prescribed Pur-Bloka and would like to know the following: 1) What ailments is this tablet directed at? 2) Can the use of this medication affect her sense of smell if she had bronchitis a couple of months before starting the medication. 3) She has always suffered from low blood pressure - is this the correct medication or do you think her blood pressure may have gone up at the time of it being prescribed? 4) She shakes quite a bit and was told that this medication would help - it seems to have got worse? 5) She wants to stop this medication - can this be done gradually?
