Pedialyte is generally safe to use even after 48 hours of opening. However, its effectiveness at treating dehydration decreases over time. After 48 hours, Pedialyte may start to lose some of its electrolyte content and become less optimal for rehydration. But it likely won’t cause any harm if consumed. The main risk is that it may not hydrate as quickly or fully as a fresh bottle would. As long as it has been stored properly and the bottle is not damaged, expired Pedialyte can still help provide hydration, electrolytes, and nutrients when you are sick. But it’s always best to use Pedialyte as soon as possible after opening.
What is Pedialyte?
Pedialyte is an oral electrolyte solution that is used to treat dehydration caused by vomiting, diarrhea, fever, and sweating in infants, children, and adults. It helps replenish vital electrolytes, nutrients, and fluids lost through dehydration.
- Water – to rehydrate the body
- Electrolytes – sodium, potassium, chloride – to replenish electrolyte loss
- Dextrose – provides carbohydrates for energy
- Citrate – to prevent excess acidity
- Zinc – supports immune system function
It comes in ready-to-drink bottles as well as powder packets that can be mixed with water. It is available in several flavors and types – original, unflavored, and with added zinc.
Why is it important to use Pedialyte promptly?
Pedialyte is formulated to provide optimal rehydration when used shortly after opening or mixing. Here are some reasons it’s best to use it within 48 hours or according to package directions:
- Preserves electrolyte content – Levels of sodium, potassium, chloride, and other electrolytes start to diminish over time after mixing.
- Avoids degradation of ingredients – Vitamins, zinc, and other nutrients can degrade in quality.
- Prevents bacterial growth – Once opened, Pedialyte is more susceptible to mold, bacteria, and general spoilage.
- Provides peak efficacy – Using Pedialyte promptly ensures you get its full rehydration and electrolyte replenishment benefits.
- Follows manufacturer guidelines – Instructions on the packaging indicate best use within a certain timeframe, usually 24-48 hours.
So while Pedialyte won’t immediately go “bad” after 48 hours, its quality slowly decreases meaning it may not provide the same level of hydration and nutrient replenishment.
What happens if you drink Pedialyte after 48 hours?
Here’s what happens if you use Pedialyte past the recommended 48 hour window after opening:
- Reduced electrolyte levels – Some electrolytes like sodium and potassium may start degrading, lowering their concentrations.
- Possible less absorption – Your body may not be able to fully absorb and utilize the degraded electrolyte content.
- Weaker rehydration effects – Lower electrolyte levels can make rehydration less effective if dehydration is severe.
- Changed taste – Pedialyte may start tasting flat or unpleasant due to chemical changes.
- Nutrient loss – Vitamins and nutrients may break down over time, reducing nutritional value.
- Possible GI issues – Degraded Pedialyte may cause temporary nausea, bloating, diarrhea if spoilage occurs.
However, even after 48 hours, Pedialyte likely won’t become hazardous provided it was stored properly in a cool, dry place. Its ingredients don’t become toxic or dangerous. The risk is more that it just becomes less effective and tasty.
Safety tips if using old Pedialyte
If you need to use Pedialyte that is past 48 hours, keep these safety tips in mind:
- Check for changes – Discard if you see changes in color, consistency, or smell.
- Avoid in severely dehydrated – May not fully hydrate if electrolyte content has dropped.
- Store properly after opening – Keep refrigerated and sealed.
- Watch children closely – Make sure they are tolerating it well.
- Supplement if needed – Combine with fresh fruits or hydration drinks if worried about efficacy.
- Limit volume – Stick to smaller amounts to reduce potential GI upset.
While not ideal, consuming Pedialyte past its prime is unlikely to have major consequences in otherwise healthy individuals. But replacing electrolytes from alternate beverages may be more effective.
How long does Pedialyte last once opened?
The exact shelf life of Pedialyte depends on the specific product, but in general Pedialyte lasts:
- Powder packets – 12 months unopened, 24 hours once mixed.
- Ready-to-drink bottles – 24-48 hours once opened.
- Generic/store brand – 24 hours once opened.
Proper storage extends Pedialyte’s shelf life. Keeping it refrigerated and sealed limits degradation. The timeframe is shorter for ready-to-drink versions versus powder because the mixing process compromises sterility.
Here are some signs that opened Pedialyte may be spoiled and should be discarded:
- Change in color or cloudiness
- Change in smell or taste
- Fizzing, bubbling, or mold
- Bottle damage like leaks or cracks
- Passed expiration date
If your symptoms worsen after drinking expired Pedialyte, seek medical attention, as bacteria growth is possible. Otherwise, replace it with a fresh, sealed bottle.
Does expired Pedialyte still work?
Pedialyte that has passed its expiration date can still provide hydration, but may not be as effective at rehydrating and replacing electrolytes compared to fresh Pedialyte.
Here’s the effect of expired Pedialyte:
- Reduced electrolytes – Sodium and glucose degrade over time lowering electrolyte content.
- Less absorption – Your body won’t properly absorb the lower electrolyte levels.
- Poor taste – Flavor and chemical composition starts changing.
- Upset stomach – Potential nausea or diarrhea from altered formula.
While drinking expired Pedialyte isn’t recommended, it likely won’t make you sick if you follow proper storage and the product shows no outward signs of spoilage. Its electrolyte profile just may not be as strong.
If signs of dehydration persist after drinking expired Pedialyte, you may need an alternate source of electrolyte replenishment and should contact your doctor. Drink plenty of water in the meantime.
Tips for using expired Pedialyte
If faced with only having expired Pedialyte, here are some tips:
- Smell and inspect it before use.
- Test a small amount to check for tolerance.
- Drink in smaller quantities spaced out.
- Combine with fresh water or hydrating drinks.
- Monitor for side effects like GI distress.
- Avoid in severe dehydration scenarios.
- Check expiration date and don’t use if more than 3-6 months past.
While not ideal, expired Pedialyte can offer some degree of hydration in a pinch provided it hasn’t gone bad. But replacing it with a non-expired product is recommended when possible.
Does Pedialyte need to be refrigerated after opening?
It’s recommended to refrigerate Pedialyte after opening to maintain quality and shelf life. The cold temperature helps:
- Preserve electrolyte content – Slows degradation of sodium, potassium, etc.
- Prevent bacterial growth – Refrigeration inhibits microbial growth.
- Maintain flavor – Keeps original taste by slowing chemical changes.
- Extend shelf life – Doubles shelf life from 24 to 48 hours when chilled.
- Follow guidelines – Manufacturer labels recommend refrigeration after opening.
However, refrigeration is not absolutely mandatory. An unopened bottle of Pedialyte has a long shelf life at room temperature. Once opened, its shelf life decreases but room temperature storage won’t instantly spoil it.
If keeping Pedialyte refrigerated after opening isn’t possible, here are some tips:
- Store in cool, dry place away from sunlight.
- Keep tightly sealed between uses.
- Limit time at room temperature to less than 24 hours.
- Avoid extreme heat over 90°F (32°C).
- Inspect carefully before use if stored at room temperature.
- Discard after 24 hours if any changes in taste or odor.
Refrigeration isn’t essential but optimizes Pedialyte’s shelf life. As long as you follow proper storage guidelines, room temperature is acceptable for short periods. Monitor closely for any changes if not refrigerated.
Can you freeze Pedialyte?
You can safely freeze Pedialyte to extend its shelf life beyond the standard 24-48 hours once opened. Freezing stops chemical changes that degrade the electrolyte content.
Here are some freezing tips:
- Store in air-tight container to prevent freezer burn.
- Lay bottles on side to avoid cracking from expansion.
- Thaw completely in refrigerator before use.
- Avoid refreezing once thawed.
- Inspect for separation or color change after thawing.
- Use within 24 hours after thawing.
- Don’t store for more than 3-6 months in freezer.
Freezing ready-to-drink Pedialyte works best. The powder form doesn’t freeze as well. Letting the bottles fully thaw preserves the formula.
The main downside is Pedialyte may absorb some freezer odors. But freezing allows you to store Pedialyte safely for future use in a pinch when someone is dehydrated or sick.

The Bottom Line
Pedialyte is still generally safe to consume even after 48 hours, especially if properly stored. However, its quality begins decreasing so it may not provide the same rehydration and electrolyte benefits compared to fresh Pedialyte. While not ideal, it likely won’t cause major issues if consumed past 48 hours as long as it was refrigerated and the bottle remains sealed. Check for changes in taste, smell, or appearance before use. Discard bottles more than 3-6 months past expiration. When possible, try to replace expired Pedialyte with a fresh, unopened bottle for the best results.
