What You Should Eat During and After Antibiotics

Taking probiotics before, during, and after antibiotic treatment may support your digestive system and lessen adverse effects, such as diarrhoea. Consuming prebiotic and high-fibre meals may also be beneficial.

Antibiotics are an effective first line of treatment for bacterial illnesses.

However, they occasionally result in adverse reactions like diarrhoea and liver injury.

While some meals may help to mitigate these adverse effects, others might exacerbate them.

What you should and shouldn't consume before, during, and after taking antibiotics is covered in this essay.


What Are Antibiotics?

A class of medications called antibiotics is used to address bacterial infections. They function by halting the illness or halting its growth.

Antibiotics come in many various varieties.

Some are broad-spectrum, which means they work against a variety of germs that cause illness. Others are made to eradicate specific bacterial species.

When managing severe infections, antibiotics are crucial and highly efficient. However, they might also have some undesirable adverse effects.

For instance, taking too many antibiotics can harm your liver. According to one research, antibiotics are the most frequently prescribed drug to harm the liver.

The numerous billions of bacteria and other microbes that reside in your gut may also be adversely affected by antibiotics. The intestinal microbiota is the term used to describe all of these microorganisms.

Antibiotics may also destroy healthy bacteria in addition to bacteria that cause illness.

Too many drugs, particularly early in life, can significantly alter the numbers and varieties of microbes in the gut microbiota.

In reality, taking antibiotics for just one week can alter the composition of the gut microbiome for up to a year.

According to some research, early-life antibiotic overuse may even alter the gut flora, increasing the risk of weight growth and obesity.

drug resistance can develop as a result of drug overuse, rendering them useless for eradicating disease-causing germs.

Finally, antibiotics may result in intestinal adverse effects, such as diarrhoea, by altering the types of bacteria that reside in the bowels.


Infections must be treated with antibiotics. Overuse, however, can harm the liver and result in long-term alterations to the beneficial intestinal flora.

Take Probiotics During and After Treatment

Antibiotic-associated diarrhoea, particularly in infants, can result from antibiotic use because it changes the gut flora.

Fortunately, several studies have demonstrated that consuming probiotics or live healthy bacteria, can lower the chance of diarrhoea brought on by antibiotics.

Taking probiotics alongside antibiotics can cut the chance of diarrhoea by more than 50%, according to a review of 23 trials with nearly 400 children.

Similar findings in both adults and children were discovered in a broader evaluation of 82 trials with over 11,000 participants.

These trials demonstrated the superior efficacy of probiotics containing Lactobacilli and Saccharomyces.

Probiotics, which are typically bacteria themselves, can, however, also be killed by drugs if consumed concurrently. As a result, it's crucial to take vitamins and medications at least a few hours apart.

Additionally, probiotics should be taken after a run of antibiotics to replenish any beneficial flora that may have been killed in the intestines.

According to one research, consuming probiotics can help the microbiota recover from a disruptive incident like taking antibiotics.

It might be preferable to take a probiotic supplement that includes a variety of probiotic organisms rather than just one if you take antibiotics first.


Probiotics should be taken a few hours apart from antibiotics to decrease the chance of diarrhoea while taking antibiotics. After taking antibiotics, probiotics can aid in restoring the balance of the intestinal flora.

Eat Fermented Foods

After drugs have harmed the gut flora, certain nutrients can aid in its restoration.

Yoghurt, cheese, sauerkraut, kombucha, and kimchi are just a few examples of foods that are created by microorganisms during the fermentation process.

They contain a variety of beneficial bacterial species, including Lactobacilli, which can aid in the recovery of the gut microbiome following the use of drugs.

According to studies, individuals who consume yoghurt or fermented milk have greater levels of Lactobacilli and reduced levels of pathogenic bacteria like Enterobacter and Bilophila Wadsworth in their intestines.

Fermented soy milk and kimchi both have health benefits and can support the growth of Bifidobacteria and other helpful gut bacteria.

Therefore, consuming fermented foods may assist after taking antibiotics to enhance gut health.

The benefits of fermented meals during antibiotic therapy have been discovered in other research as well.

Some of them have demonstrated that consuming yoghurt with or without probiotics can lessen diarrhoea in individuals taking medicines.


Healthy bacteria found in fermented foods, such as Lactobacilli, can help repair antibiotic-induced harm to the microbiome. Yoghurt may also lessen the chance of diarrhoea brought on by antibiotics.

Eat High-Fiber Foods

Although fibre cannot be metabolised by the human body, it can be by gut bacteria, which encourages the development of those bacteria.

fibre may therefore aid in the recovery of healthy intestinal flora following a drug regimen.

Foods high in fibre include:

  • Broccoli
  • Nuts
  • Artichokes
  • Lentils
  • Whole grains (porridge, whole grain bread, brown rice)
  • Berries
  • Seeds
  • Peas
  • Bananas
  • Beans

Studies have demonstrated that dietary fibre-rich foods can both promote the development of beneficial bacteria in the intestines and possibly inhibit the growth of some harmful bacteria.

However, dietary fibre can reduce the rate of gastric emptying. The rate at which medications are metabolised may then be slowed as a result.

Therefore, it is best to briefly avoid consuming high-fibre foods while receiving antibiotics and instead concentrate on doing so once the therapy is over.


Whole grains, legumes, fruits, and veggies are examples of high-fibre meals that can promote the development of good gut flora. They should be consumed after taking antibiotics, not while taking them, as fibre may inhibit the uptake of the medication.

Eat Prebiotic Foods

Prebiotics are foods that nourish the beneficial bacteria in your stomach, as opposed to probiotics, which are living organisms.

Many meals rich in fibre are prebiotic. Healthy intestinal microbes metabolise and ferment the fibre, which helps them develop.

Other meals, though low in fibre, serve as prebiotics by promoting the development of beneficial microbes like Bifidobacteria.

For instance, antioxidant polyphenols found in red wine are metabolised by intestinal microbes rather than human cells.

According to one research, drinking red wine polyphenol extracts for four weeks increased the number of beneficial Bifidobacteria in the gut while also lowering blood pressure and cholesterol levels.

Similar prebiotic effects on intestinal flora can be obtained from antioxidant flavonoids found in chocolate.

According to a few studies, cocoa polyphenols also boost beneficial Bifidobacteria and Lactobacillus in the intestines while decreasing harmful bacteria like Clostridia.

Prebiotic foods can therefore aid in the development of good gut microbes that have been harmed by drugs.


Prebiotics are foods that promote the development of good bacteria in the stomach and may aid in the recovery of the gut flora following antibiotic use.

Avoid Certain Foods That Reduce Antibiotic Effectiveness

Although many meals are advantageous both during and after antibiotic use, others need to be shunned.

For instance, research has shown that consuming grapefruit and grapefruit juice while taking certain medicines, such as antibiotics, can be harmful.

This is because cytochrome P450 is an enzyme that breaks down both citrus juice and many medicines.

While taking antibiotics, eating grapefruit can hinder the body from correctly metabolising the medicine. Your health may suffer as a result.

According to research done on six healthy males, drinking grapefruit juice while taking the antibiotic erythromycin led to higher blood levels of the drug than those who took it with water.

Calcium-fortified foods may also have an impact on how well antibiotics are absorbed.

Studies have demonstrated that meals with calcium supplements can lessen the uptake of different antibiotics, such as ciprofloxacin (Cipro) and gatifloxacin.

Yoghurt, for example, contains calcium, but other research has found that it doesn't have the same inhibiting impact.

The only meals to stay away from when taking antibiotics may be those that have high calcium supplements.


Foods enriched with calcium and grapefruit can both influence how well drugs are absorbed by the body. When taking antibiotics, it is recommended to avoid consuming these foods.

The Bottom Line

The use of antibiotics is crucial if you have a viral illness.

However, they occasionally result in adverse reactions, such as diarrhoea, liver illness, and modifications to the intestinal flora.

Taking probiotics before, during, and after antibiotic treatment can help lower the risk of diarrhoea and improve the health of your intestinal flora.

A healthy gut flora may also be restored by consuming high-fibre foods, fermented foods, and prebiotic foods after taking antibiotics.

However, since these foods can interfere with the uptake of antibiotics, it is best to avoid citrus and foods fortified with calcium while taking antibiotics.
