Why wouldn’t a medication with both an expectorant and a cough suppressant cancel each other out?

In: 1

Answer 1

Expectorants are intended to make mucus thinner and easier to cough up.

Cough suppressants are intended to stop you coughing, be causing coughing can be irritating.

Cough suppressants are a bad idea generally, as coughing is an essential part of keeping the lungs clear especially when there is an infection.

That said, it doesn’t really matter. There are no readily available Expectorants and cough suppressants which actually work.

Expectorants as a general rule don’t work at all. Cough suppressants like morphine and heroin are avaialable but generally only used for terminal cases.
