My Pulmonologist Increased My Prescribed Does Of Zenhale To 2

My pulmonologist increased my prescribed does of Zenhale to 2 puffs, four times a day for a period of two weeks. I have been experiencing muscle spasms in my legs , feet , lower back. Now that I am back to the regular dose of 2 puffs twice a day I am still experiencing muscle spasms, though to a lesser degree.
This concerns me. I would prefer not to be on this drug, yet my doctor insists I stick with the lower dose.
I am also on Coversyl Plus for Hypertension.
I would like to have your opinion on this situation. Karen Olscamp
