Is it okay to use expired Dimetapp? 

It is not okay to use expired Dimetapp. It is one of the most trusted syrups to use in 6-12-year-old children for the management and treatment of the common cold and flu. 

Expired Dimetapp has no guarantee from the manufacturer regarding its safety and efficacy and you don’t want to take such a risk with your child. I would never recommend giving expired Dimetapp to a child. 

What are the possible dangers associated with the use of expired Dimetapp? 

Expired Dimetapp may or may not inevitably harm your child. Although medications are expected to lose their efficacy once they expire, other potential health risks could also be present. The storage conditions of Dimetapp can also make a huge difference. 

There is a reason why medications have expiry dates and it’s not even recommended for adults to use meds past the expiration date, let alone children. It’s best to not use expired Dimetapp (1). 

What to do if you have accidentally given your child an expired Dimetapp? 

If you have accidentally given your child expired Dimetapp and you notice some unusual symptoms, like sleepiness or any sign of an allergic reaction on your child’s skin, reach out to your healthcare provider immediately.

A dose or two of expired Dimetapp will most likely not harm your child, but some children are way more sensitive than others. Make sure you discard the expired medications according to the manufacturer’s directions and keep all the meds out of reach of your children.
