Should azithromycin dry suspension be mixed with boiling water?
Generally, azithromycin dry suspension should not be mixed with boiling water. It is recommended to use an appropriate amount of cool or lukewarm boiled water for preparation, as excessively high water temperature may affect the stability and efficacy of the medication. If in doubt, it is advisable to consult a healthcare professional beforehand. Detailed explanations are as follows:

Cool boiled water or lukewarm water (typically recommended at 20–40°C) can be used for mixing. This temperature range allows the drug powder to dissolve fully and form a uniform suspension without damaging the structure of the active ingredients, ensuring normal therapeutic effectiveness. Additionally, the resulting liquid will be at a comfortable temperature for immediate consumption, making it especially suitable for children, elderly individuals, and other sensitive populations.
Boiling water should not be used, as high temperatures (above 60°C) may cause decomposition or denaturation of the active components, reducing the drug's efficacy and potentially generating unknown degradation products that could increase the risk of adverse reactions. Furthermore, using boiling water may cause the powder to clump, making it difficult to dissolve completely. This could lead to inconsistent dosing, reduced treatment effectiveness, and irritation to the mouth and gastrointestinal tract.
When preparing azithromycin dry suspension, always check the water temperature first, add the specified amount of water according to the dosage instructions on the product label, shake thoroughly, and take immediately. If the reconstituted solution has an unusual odor or visible sediment before administration, discontinue use and consult a doctor promptly.
