How come one gave me certain side effects and not other side effects. Hydrocodone can only be given orally. The duration of action is similar - about 5 hours. Hydrocodone has a slightly longer plasma half-life. From a practical point of view they are nearly equivalent.
Next time try any cough medicine with dextromethorphan.
It seems to act centrally to change the threshold of coughing and is equivalent to codeine in controlled studies. It generally has fewer side effects, especially sedation and constipation. About two weeks ago I developed a pretty bad cough. Lately I've found it difficult to breathe, especially in the morning and right after coughing. The phlegm that I bring up is clear and kind of thick.
