Pediatrician Dr Saurabh Kapoor recently cautioned against using opened cough syrups beyond a month. “Once opened, don’t keep any cough syrup beyond a month. They have to be discarded after a month as their potency goes down. In this case, don’t go by the expiry date. Once opened, don’t follow the expiry date,” he said on a podcast with Harman Hardy, adding that the advice applies to children and adults.
To verify this, we reached out to other experts.
Dr Paritosh Baghel, senior consultant, internal medicine, S L Raheja Hospital—A Fortis Associate—said syrups of various kinds are used to treat multiple medical ailments, ranging from coughs and colds to constipation and other illnesses.
“It is advisable to consume medication that comes in syrup as per a doctor’s prescription. Patients often do not finish these bottles for syrup and keep them away for use later, if similar symptoms arise, as these bottles have lengthy expiry dates. However, we should be aware that using previously opened bottles of medicines later may be associated with many risks,” said Dr Baghel.

Dr Shrey Srivastav, MD (internal medicine), consultant physician, Sharda Hospital, Greater Noida, concurred and shared that opened syrups should not be used beyond a month due to contamination risk as the exposure to air and bacteria can lead to microbial growth. “Active ingredients may degrade, making the syrup less effective,” said Dr Srivastav, adding breakdown of components can create harmful byproducts.
What happens if you use such syrups?
Dr Baghel said that the effectiveness of these syrups may be diminished, they may not act well at a later date, and may not bring the intended relief. “You may also end up using large quantities of it since it will not work as prescribed,” said Dr Baghel.
According to Dr Baghel, they may be contaminated with bacteria or fungi, as most of these syrups are sugar-based and hence have a high chance of contamination if not stored in an airtight bottle. “The risk of getting a new infection or gastric upset because of the contamination is possible,” said Dr Baghel.
If you notice any changes in taste, colour, or mould or unusual growth inside the bottle, discard it immediately to avoid potential health risks.
“Lastly, and most importantly, strictly avoid self-medicating, especially with syrups or other prescription medicines, as it can lead to unintended side effects, misuse, or harmful interactions with other medications. Always consume medications after taking doctor’s advice,” said Dr Baghel.
