Hypoallergenic formulas are formulas designed especially for babies who have allergic reactions. They are different from regular formulas, and are not so many on the market. Similac Alimentum is one of these few wonder-working hypoallergenic formulas, which helps babies who are fussy due to colic or indigestion, or lactose intolerance. The benefits do not stop here; it also helps babies who are sensitive to protein.

But these praises are not without a few drawbacks. No product is actually without one. So, in this article, you will learn the 7 side effects of Alimentum that most people have no knowledge of. Read on!

How Long Does It Take For Similac Alimentum to Work?

Similac Alimentum is designed to ease crying in babies in a period of just twenty-four hours. This is probably some good news for parents who have colicky babies, as it makes Similac Alimentum worth the cash. And as a matter of fact, the side effects of Similac Alimentum are not all that critical.

It is just that there are cases where the formula fails to reduce crying in babies within the promised twenty four hours. But many mothers enjoy the results even if they do not surface until some days after.

Similac Alimentum Causing Gas

First off, there is a need to know that Similac Alimentum is a not a regular but hypoallergenic formula. What this means is that it comes with broken down proteins. This helps your baby’s system receive this food with little or no stress.

Similac Alimentum has a number of side effects, which can be managed provided you have the right information.

One of the side effects of Similac Alimentum is gas, but the occurrence is not usual and will disappear once your baby gets a hang of the formula.

Can Similac Alimentum Make Baby Worse?

It is almost true that all formulas can only be fully understood when you use them firsthand. But you do not necessarily need to wait, and that is why we are here.

Similac Alimentum is thin in texture, and this fact has been why a handful of parents say their babies got worse on it. Because it is thin, it rarely stays down. If you notice your baby’s condition is deteriorating

with Similac Alimentum, a reasonable solution is to switch to soy, and maybe try meds. In short, go for another formula, of course not without your doctor’s recommendation.

Similac Alimentum Making Baby Spit Up

Spitting up is another side effect of Similac Alimentum. It is something that most parents complain about. Supplementing with formula could have made all the sense, but it may not be as productive as expected. 

Switching to another formula makes sense too. But what if your baby is on Alimentum prescription? Here is an alternative: use a thickener called ‘Simply Thick’. This makes more sense because Similac Alimentum has a thin texture, and so your baby spitting up is not something strange.

But with the help of a thickener, everything will be well okay.

Similac Alimentum Not Making Baby Sleep

The connection of Similac Alimentum with sleeplessness in babies is not exactly defined, and can occur coherently with other unnoticed symptoms. For instance, if your baby has reflux, then it is reasonable that she is still so disturbed by it that lying down is not a soothing experience. 

Another thing to know is that formulas like Similac Alimentum are somehow thin in texture, and sometimes require a thickener to make things better.

If after trying out this alternative, the condition persists, please feel free to consult your pediatrician.

Is Alimentum Less Filling?

 Similac Alimentum comes with already broken down proteins, which makes for easy absorption and digestion by your baby. What happens is just that, this easy digestion makes the formula vanish from your baby’s system in a little time, and what is the point if a formula won’t at least keep your little one going for some time?

What you can do in this case is, add rice cereals to your daughter’s bottle of Similac Alimentum. The result will amaze you, as you will find that your little one is able to keep the formula down and full.

Similac Alimentum Not Making Baby Poop

It is possible that Similac Alimentum can prevent some babies from pooping for a particular period of time. However, you should note that this issue is not universal, but peculiar to the way different children, and their body systems work. 

If your baby stops having bowel movements on Similac Advanced, switching to Sensitive can be the sensible thing to do. It may take about one week, but her bowel movements will return back to regular, and she will be able to poop for 2-3 times each day. 

If this symptom persists, you should consult your doctor.

Similac Alimentum Making Baby Scream

If you find that your baby screams a lot on Similac Alimentum, the first to know is that the issue is not specific to you. Many parents have had and have a similar issue. 

Alimentum is actually thin, and this single fact is responsible for ninety percent of its side effects. It leaves babies throwing up most of the times. 

You can do two things about this: Mix it proportionately with breast milk, or switch to Alimentum Sensitive, if you were on Advanced, or consider another great formula, with the recommendation of your physician, of course!


Similac Alimentum is not only a fantastic formula, but also a top, if not the best hypoallergenic formula. For a long time, it has helped countless children with allergy issues, colic, and other food problems.

While it is okay to know that there is no product without a side effect or two, the side effects of Similac Alimentum do not necessarily discount the fact that it is amazing. This information is just to help you get familiar with all the details you need to know about Similac Alimentum. And we hope it helps you make an informed shopping choice.
