Cheratussin AC (also known as Robitussin AC) is a combination ingredient cough syrup that contains codeine and guaifenesin. It is typically prescribed to control cough for those suffering from bronchitis and upper respiratory tract infections. As Cheratussin AC contains codeine, a CNS (central nervous system depressant), it is not recommended to take with other CNS depressants like Xanax (alprazolam).
The use of codeine (from Cheratussin AC) and alprazolam together has the potential to cause additive side effects including:
While the small amount of codeine contained in Cheratussin AC most likely won't cause serious effects (such as respiratory depression) when used with alprazolam, their use together is nevertheless not recommended. If they must be used together, it is important to use the lowest effective dose of Cheratussin AC and limit the duration of therapy as necessary.
The two drugs can be used in the same day if they are separated from one other by an appropriate amount of time. The effects of Cheratussin AC generally last 4 to 6 hours, while the effects of alprazolam can last between 8 to 12 hours. If necessary, try to separate doses as far apart as possible.
