Your cramping may be due to your increased water intake along with the Qvar™ Inhaler (beclomethasone dipropionate HFA).
Cramping is a possible steroid side effect. It is rare to have side effects with an inhaled steroid, like the Qvar™ Inhaler (beclomethasone dipropionate HFA). However side effects are more likely to occur with higher doses of an inhaled steroid. So it is possible that your ankle and foot cramping is due to the Qvar™ Inhaler (beclomethasone dipropionate HFA). Please check with your doctor to be sure. Also talk to your doctor about changing your Qvar™ Inhaler (beclomethasone dipropionate HFA) to the lowest dose that will control your asthma and emphysema.
God bless.
