Will ibuprofen break a fast?

Let’s face it, fasting can be tough. We’re not used to eating less or going without food for long periods of time. It requires discipline, commitment and willpower of steel. But what happens when we need medication, like ibuprofen? Can we take it while fasting or will that break our fast? In this article, we’ll delve into the topic headfirst and get you the answers you need.

What is Fasting?

Before we dive deeper into our main subject, let’s quickly cover what fasting actually means.

Fasting refers to voluntarily abstaining from all or some kinds of foods (and sometimes liquids as well) for a specific period of time. People typically fast for religious reasons or for health benefits such as weight loss or improved mental clarity.

There are several types of fasting including time-restricted feeding, intermittent fasting (IF), alternate-day fasting (ADF), and extended water-only fasts.

Time-Restricted Feeding

Time-restricted feeding involves limiting your eating window to a set number hours each day – usually around 8-10 hours – with no food consumption during the remaining hours.

It’s like an “all-you-can-eat” buffet with restricted serving times!

Intermittent Fasting

Intermittent Fasting involves cycling between periods of normal eating and calorie restriction over a certain period – often 12-16 hours per day – extending up to days at times!

Basically; You say bye-bye calories today but come tomorrow….you’re BFFs again!.

Alternate-day Fasting

Alternate Day Fasting is defined as abstaining from food on alternative days which eliminates patient’s chances of insulin resistance significantly!

Doctors recommend it because…well who wouldn’t want shirker heart diseases in their history! except if you live under rocks…you know pineapples are always better than apples!

Extended Water-only Fasts

Finally, the most extreme form of fasting is extended water-only fasts which last for several days or even weeks at a time. These shouldn’t be undertaken without proper medical guidance and supervision.

Basically, You’ll eat when human history decides you will! C’mon we’re not that primitive…or are we??

What does Ibuprofen Do?

Ibuprofen belongs to the class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing inflammation and pain by blocking certain enzymes in your body – specifically cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2).

The role played by these two enzymes? Well, /Cyclooxygenase breaks down fatty acids into Prostaglandins/. Prostaglandins regulate important effects including blood pressure regulation smooth muscle contraction/relaxation. They also promote inflammation and fever in response to infection.

This makes ibuprofen particularly useful for treating conditions like headaches, migraines, menstrual cramps, toothaches, arthritis-related pain/inflammation.

In case you missed it – Ibu means reducing prostaglandins generation hence reduction of inflammation! Don’t ask me about prostaglac-diagram; aheem…I was dailydreaming during biology classes… blame public schools!!.

Does Taking Ibuprofen Break A Fast?

Let’s cut to the chase – Can taking ibuprofen break a fast? The short answer is No!

But the long answer requires us considering what type of fasting you’re adhering to. And So let’s take each one briefly:

Time-Restricted Feeding & Intermittent Fasting

If you’re following either time-restricted feeding or intermittent fasting routine whereby only drinks or meals with limited calories are consumed during the fasting intervals, then taking ibuprofen with such drinks or meals won’t break your fast.

Yay! Now you can finally go off all day without gnawing on that bullet. you got this – just add some salt!

Alternate-day Fasting

If alternate-day fasting is your thing, it’s best to time your ibuprofen consumption along with an allowed meal to avoid giving rise to any reverse effects like gastrointestinal irritation and inflammation commonly associated with NSAIDs and food deficiency respectively.

Ahem…we’ve heard its common sense enough times haven’t we? If some of us (looking at myself) had listened more carefully in prep school, we wouldn’t have been learning this now would we? Anyway let’s move on quickly before anyone else recognizes me…

Extended Water-only Fast

For extended water-only fasts lasting for several days up to several weeks even over a month: We want only light medication or minor pain relief measures taken combined alongside medical supervision as recommended- better yet consult your physician beforehand!

Benefits Of Taking Ibuprofen While Fasting?

Yes!! There are benefits of taking Ibuprofen while fasting when it is well managed medically since:

1) It reduces inflammation^

2) Relief migraine symptoms, cramps.and headaches due muscle relaxation impacts.^#

3) Promoting healing process whereby facilitating proper blood flow which eliminates toxins.#$

4) Using mild analgesics/anti-inflammatory medications like will prevent induction of inflammatory responses such as cytokine production and improves metabolic disease complications induced by long-term diet-induced obesity.$@%.

5) Lastly prevents ‘Insulin Resistance’,$$$ hence reducing chronic ailments problems.

Inflammation often increases after prolonged fasting but taking certain anti-inflammatory drugs helps counteract this effect.

$ Better immune response is maintained hence quicker recovery from illness.
@Obesity is known to cause chronic inflammation which leads to metabolic problems like diabetes and heart disease. Mild pain relief medication reduces such chances
%Talk about killing 2 birds with one stone…
$$ Insulin Resistance causes changes in blood sugar levels and can lead to several chronic diseases! not taking Ibuprofen during fasting can could be more trouble than its worth.

It’s important that you don’t rely too much on ibuprofen as a crutch, though – especially if weight loss is your goal. Taking too many NSAIDs has been linked with stomach ulcers, GI bleeding and poor cardiovascular health if taken in high doses over long periods of time.

Alternatives To Ibuprofen While Fasting

If ibuprofen isn’t an option for you while fasting due to certain reasons like history of allergy or contraindication … here are some alternatives:


Acetaminophen (Tylenol) is an over-the-counter medication used for pain relief which does little impact on the lining of the stomach wall when compared with other NSAIDs.

It’s basically that guy next door who constantly tells Auntie Martha she looks younger by day but doesn’t disclose any expectations/demands

Acetaminophen also works by blocking COX enzymes; specifically COX-3 although it’s still somewhat unclear how they work!

Side effects include limited effectiveness against inflammatory conditions like arthritis & liver damage at high doses/overuse 😲…so be careful out there guys!!!


Celecoxib (Celebrex) belongs to the same class of drugs as ibuprofen i.e., NSIADs however boasts fewer gastrointestinal-related side effects since it mainly blocks only COX-2 enzyme.

Basically he just sticks up for his immediate friend group aka Bowel/Gastric tract reducing collateral damage.

However, high dosages cause similar side effects as ibuprofen like increased risk of blood clots and are associated with higher cardiovascular risks hence not recommended for long-term use.


Capsaicin is the spicy compound found in chili peppers and has been known to help alleviate pain symptoms during chronic condition [arthritis] while reducing inflammation.

You may know it as the missing spice (we all have that one cousin who uses too much!) or temporary flavor king on your daily entrees but now serves an extra purpose!

It usually comes in topical creams/salves so it does not interfere with your fasting regimen and poses fewer GI tract-related problems than most NSAIDSs…talk about a win-win!!!ªª
(A little caveat though – watch out when frying chicken around this bad boy)


In summary, Ibuprofen won’t break a fast if consumed appropriately – however instead of relying solely on medication focus more on laying healthy foundations for improved medical conditions by adopting healthier lifestyle choices such as diet restrictions/exercises/regular visits to a medical professional!
