Take the syrup for half an hour and then drink water.

After taking cough syrup, the syrup covers the surface of the mucous membrane in the throat, utilizing the viscosity of the syrup agent to localize the therapeutic effect in the throat. For example, the syrup contains menthol, which has the effect of contracting the blood vessels of the oral mucosa, reducing inflammation, edema and pain; peppermint oil has the effect of cooling and relieving itching, anti-inflammatory and analgesic, and expectorant and phlegm; licorice infusion has the effect of protecting the mucous membranes of the pharynx and suppressing cough.

If you drink a lot of water immediately after taking cough syrup, it will reduce the concentration of the drug in the pharynx, thus affecting the effectiveness of the drug. Therefore, the general recommendation is that you can drink water normally half an hour after drinking the syrup.
