Numerous off-label prescriptions have been getting used, together with frequent anti-anxiety and anti-depressant medication like benzodiazepines and SSRIs.

Mirtazapine, a typical antidepressant, was one of many varieties of medication being prescribed. Case sequence and early research confirmed it had potential. Nonetheless, on this worldwide trial, the primary large-scale research to be carried out, researchers discovered that mirtazapine doesn’t enhance breathlessness in sufferers with respiratory illness in contrast with placebo.
