I had a pretty annoying dry cough a while ago following a cold. In the list of incredients for a cough syrup that I used, it said:
Each 5 mL or 1 teaspoonful (tsp.) contains:
- DM | Cough Suppressant: Dextromethorphan Hydrobromide (15 mg): Controls dry cough.
- E | Expectorant: Guaifenesin (200 mg): Relieves chest congestion.
- Analgesic: Menthol (15 mg): Relieves sore throat pain.
Okay, seems straightforward enough.
Note that part of the article says:
It's important to understand that these studies have not proven that cough medicines don’t work. Rather, they’ve just found no proof that they do. It’s always possible that further studies could show that they help.
The comments in the reddit thread didn't seem to have any clear consensus about the validity of the article's claims, so I thought I'd ask here. I was wondering specifically about the Dextromethorphan. Is there any evidence that DM suppresses coughing?
