Similac Alimentum Side Effects

Similac Alimentum Side Effects

Every medication we put into our bodies has at least one side effect. Not a single pill, capsule, ointment, cream, or powder is exempt. Unfortunately, that includes baby powder formulas like that of Similac Alimentum. Yes, it’s true. Similac Alimentum side effects are real and they can be happening or could futuristically happen to your little one.

That’s why it’s so important to know and understand the risks associated with everything you’re putting into your child’s body. If you are hesitant or have any questions at all, do not continue to feed him or her a certain powder or baby formula. Always check in with the pediatrician to see what’s right and what’s best for your baby, as they know details about powders and formulas that may not be in bold on the boxes or cans.

If you want a quick pick-me-up, handy-dandy guide on the side effects of Similac Alimentum, keep on reading and share it with your friends and family who have babies, too.

Diarrhea: The Most Popular Similac Alimentum Side Effect

Yes, Similac Alimentum does eliminate the colic your baby is experiencing about 24 hours after he or she consumes this popular formula. On the other hand, this meal plan you’re putting your baby on has other unwanted results a day or two after consumption.

We suggest that you keep a close eye on your baby’s diapers starting 24 hours after the formula switch. If there is constant diarrhea, your best next step would be to contact your pediatrician. Though this is common, it is still unwanted and may lead to additional side effects, like the ones listed below.

Weakness & Fatigue Are Close Follow Ups To Diarrhea

Diarrhea can naturally lead to weakness and fatigue in a baby, which is why we mentioned above that the watery stools can lead to additional side effects.

However, parents are also finding that weakness and fatigue can spring up out of nowhere even without excessive diarrhea – quite worrisome.

Oddly enough, even though babies are experiencing weakness and fatigue and parents are witnessing it, these side effects are not present on the side of the can. That’s why we urge you to again, keep a close eye and call the pediatrician if anything seems off.

Increased Thirst & Dehydration Are Also Bad Signs

Naturally, diarrhea leads to dehydration. Dehydration will then lead to increased thirst. The stinky part is that your baby doesn’t know how to tell you he or she is craving some extra fluids. So, what do you do? Watch out for these signs:

  • Dry mouth
  • Cracked lips
  • Sunken in eyes
  • Excessive thirst
  • Irritability
  • Sleepiness
  • Lack of tears

Remember, dehydration can be dangerous for anyone, especially a baby that can’t communicate. Keeping a watchful eye will allow you to prevent anything worse from happening. If you’re unsure, it’s always best to call the doctor on call to get an answer.


All in all, consider that you’re the person that knows your baby the best in this world.

If they have diarrhea once in a while and you find diarrhea in their diaper one time after switching formulas, there may not be a problem. More than once is cause for concern.

Babies are often tired for more than 50% of the day, so if he or she is sleeping regularly throughout the night and taking regular naps, don’t overthink it. If weakness appears and your baby cannot hold his or her head up like he or she did before, that’s something to consider calling the pediatrician on.

When it comes to increased thirst and dehydration, neither of these instances are a joke to pass by. Any of the above symptoms should be taken seriously and a pediatrician should be called or a visit to the emergency room may be in order.

One thing I didn’t realize before having kids of my own, though, is how much stuff babies need—and how complicated it can all get! With so many different options out there for things like car seats, strollers, and cribs, figuring out which ones are right for your family can feel confusing and anxiety-inducing, especially alongside all the other work you have to do to prepare your home for the new arrival.
