How do medications treat mixed sleep apnea?

Medications are not usually given to treat mixed sleep apnea itself. But some cases of sleep apnea are caused by medical conditions that can be treated with drugs. For example, treating your allergies with medication might reduce your sleep apnea symptoms. Also, your doctor may tell you to avoid some medications, such as muscle relaxants, that can interfere with your central nervous system. Follow your doctor's recommendations about your treatment.
