Warning: FDA Flags Psychiatric Effects of Asthma Drugs
{{#rendered}} {{/rendered}}Federal health officials are requiring new labels on popular asthma drugs like Merck's Singulair that highlight language about suicidal behavior, depression and anxiousness seen in a small number of patients.
After 15 months of investigation, the FDA is asking Merck, AstraZeneca and Critical Therapeutics to raise warnings about psychiatric problems reported by a handful of patients taking their drugs.
A spokeswoman for Merck says the language already appears in Singulair's label, but will be raised to the "precautions" section. It's now listed in a section about various side effects reported by patients.
