For a severe, persistent dry cough, prescription-strength suppressants like codeine or benzonatate are highly effective. These medications typically begin working within 30 to 60 minutes of the first dose. However, because his cough is not responding to standard syrups, it is important to identify the underlying cause rather than just suppressing it. Persistent dry coughs can sometimes be side effects of certain blood pressure medications (like ACE inhibitors) or caused by acid reflux or asthma. Please consult his prescribing doctor to review his medications and find the root cause, which will lead to the most effective, lasting relief.
