I have been on Singulair for approx 20 years. We moved and my asthma has significantly improved! I would like to taper off the drug but want to do so safely. Can you tell me how to do this.....do i take a half pill for a few days....one pill every few days for a few weeks...? So far I took 3/4 pills for two nights and then stopped cold turkey for the next two nights. But worried this might not be safe. Please advise. Thank you!
