My guess is it’s in the millions. I don’t know enough about asthma to recommend alternatives but it seems to make sense to do some research if you’re faced with being offered a prescription of these sorts of drugs.
The U.S. Food and Drug Administration on Friday requested that the makers of a class of asthma drugs called leukotriene receptor agonists place a “precaution” on the drugs’ labeling, warning of the potential for neuropsychiatric events.
The drugs in question include the blockbuster medication Singulair (montelukast), as well as Accolate (zafirlukast). Zyflo and Zyflo CR (zileuton), drugs in a class known as leukotriene synthesis inhibitors, are also included in the labeling change.
“The reported neuropsychiatric events include postmarket cases of agitation, aggression, anxiousness, dream abnormalities and hallucinations, depression, insomnia, irritability, restlessness, suicidal thinking and behavior [including suicide], and tremor,” the agency said in a statement posted on its Web site Friday.
