Care management for individuals with Coffin-Lowry syndrome is symptomatic, supportive and based is  what is known of Coffin-Lowry syndrome.

Individuals with CLS should be monitored for progressive kyphoscoliosis (reported to occur in 80% of patients) and pectus carinatum/excavatum (in 80% of patients), and progressive kyphosis/scoliosis, which can become life-threatening if the cardiorespiratory system becomes compromised.

A sensorineural hearing defect is reported in 30% of the individuals. 

A cardiac evaluation, with attention to mitral valve dysfunction and cardiomyopathy, is recommended.

10 % suffer from a sudden loss of muscle tone induced by unexpected tactile or auditory stimuli. The events are usually not associated with impairment of consciousness.

Anti-epileptic medications, such as clonazepam, may be used to treat drop attacks, although little is known about the effect of such a treatment. Some persons with CLS suffer from epilepsy.
