COPD medications are one of three classes: Long acting muscarinic agent (LAMA); long acting beta agonist (LABA) or inhaled corticosteroid (ICS). It's generally recommended that you take only one of each. Over-medicating can cause problems in COPD, just as it can in other conditions. Check with your pharmacist if you're not sure which class your meds fall in.
