alt Hacker NewsIn my subjective experience, Dextromethorphan (DXM, as the robo-trippers call it) does almost nothing for me, in the 1-5% range
The only cold and cough medicine that really truly works is the over-the-counter stuff, pseudoephedrine, works amazing for me. I usually pick up a box of the stuff when school starts in the fall and I go through half a box of it by the following summer.
Pseudoephedrine is a decongestant to relieve the nasal/sinus congestion.
If it helps with your coughing, it’s because it’s stopping the postnasal drip, not suppressing the cough as DXM would by shutting down the cough reflex.
Two different, but very similar use cases. DXM is a god-send in the appropriate time.
