Injection Augmentation for Chronic Cough

This publication examines the results of an investigational injection augmentation treatment of six patients, with chronic cough resistant to all other treatments. The rationale for the treatment is that certain cases of chronic cough, thought to result from sensory nerve damage, might respond to a treatment typically used for motor nerve damage. In this highly selective group of patients, the treatment yielded relief. Whether the treatment is useful in a broader group of patients with cough remains to be established.
