It is not a pill. It is an injection every two weeks. It cleared the 3rd trial in May of this year with good results. Google Dupixent & COPD and read all about it. My husband has been on it since about 2018 for eczema and it has worked wonders. It is also used to treat asthma. I hope it will get final approval soon for COPD. Biologics are a new class of drugs now and seems to be working well. Husband has no side effects from it and if there are any, they seem to be minimal. I hope they can be used soon for my COPD.
