It is possible that you are overusing the inhaler and raised pulse rate (tachycardia
), pins & needles like sensation are a common side effect of excess use of bronchodilators (beta2 agonists).
If you are needing to use the abuterol >3 times a day then you need to be on streoid inhalers and use this only when required.
Combination inhalers (steroids
+ long-acting beta agonists) are to be used only when the steroid inhaler on its own is insufficient to control your asthma
The ther good combination is a steroid inhaler plus montelukast
which will require lesser use of abuterol.
Hope this helps.
