COPD
"I have been on this medication for approximately one month. When I first began taking this medication (500mcg) and was having numerous side effects. Changed regimen to taking 500 mcg every other day. Continued to have same side effects. For past two weeks, I have been taking one-half dosage (250mcg) once at night and once in the morning. This has virtually eliminated all the previous side effects. My breathing improvement has been much better and more consistent with this low dosage. The 500 mcg pills are so small that is is impossible to divide a tablet without a good pill cutter. I found one on Amazon that works great. Perfect split of 500 mcg pill each time."
