I have been salbutamol nebs for about 3 years now. Every time I end up in hospital my potassium levels are an issue. I have had to have central lines before so I can have IV potassium running at large volumes and even with that they force me to take it orally. I have not been to A&E since March and although I've recently been in hospital my potassium levels haven't been checked. Just recently I have been getting palpitations after so much as taking just a normal salbutamol inhaler I am worried this could be low potassium levels and wondering whether I should be pushing for a blood test to check this out. Is there anything else I should look out for? I know that palpitations after salbutamol are quite common but I use it alot and post sal palpitations disappeared years ago.
