What to do for a cold (cough, runny nose, sore throat) in Nha Trang — where to get medicine?

For a dry cough, ask a pharmacy about Dextro Boston; it is not recommended for a cough that produces phlegm.

Colds often come from air conditioning in hotel rooms or buses — the sharp temperature drop triggers a runny nose and sore throat, so avoid sitting directly under the cold air stream.

For a sore throat and runny nose, locals recommend just walking into the nearest pharmacy (nhà thuốc) — they're everywhere in the city and sell medicine without a prescription.

For a productive cough (with phlegm), people ask the pharmacist for an expectorant syrup, explaining symptoms with gestures or a phone translator — staff usually pick the right medicine.

For a runny nose, pharmacies offer decongestant nasal drops or spray — relief comes quickly, but they're not meant to be used for more than 3-5 days.
