No Frank, pharmacies will not sell you meds to treat cold. I know quite well that common cold is caused by rhinovirus(es). But some nice "reliving" meds are good (I used to like Sinutab Te before it was pulled). They really help you, you feel better. Of course they do not treat the ailment, merely relieving you of its symptoms, but if I should chose between having a cold for a week and not doing anything, being miserable and congested all week long, and drinking te antigripal 4 times a day and being able to at least have some work done and feeling more-or-less reasonably fine (under the circumstances) *, I prefer the latter.
* I do admit that for many Dominicans (and other nationalities as well) being free of symptoms or with reduced symptoms may mean they think they are/have been "cured".
