Pharmacy and Medication


Know your medicine and arm yourself with information about your prescription therapy to ensure effective treatment, keep you safe, and help you to be aware of potential problems.  Your Pharmacist is also an excellent medication consultant, if you have questions your Pharmacist is only a phone call away.

Antibiotics are a type of medication that fight bacteria. They work either by killing bacteria or by stopping it from reproducing.

These drugs often cause gastrointestinal side effects, such as:

These side effects may be uncomfortable, but they tend to pass quickly.

Eating the right foods can help to prevent bothersome side effects and encourage healing. In this article, learn which foods to eat and which to avoid while taking antibiotics.

What to eat during and after taking antibiotics

Certain foods or drinks may affect antibiotics.

A person has trillions of bacteria and other microorganisms living in their gut. The medical community refers to these organisms, collectively, as the gut microbiome.

Antibiotics fight bacteria, and they can upset the balance of bacteria in the microbiome.

The gut microbiome keeps the digestive system functioning and helps the immune system to defend against viral infection.

When antibiotics upset the bacterial balance, a person may experience side effects, such as nausea or diarrhea. Consuming probiotics and prebiotics during and after a course of antibiotics can help to restore the balance of bacteria in the gut.

Probiotics

Probiotics are live microorganisms commonly known as “healthy bacteria.”

They can help to reduce some of the side effects of antibiotics, such as bloating and diarrhea.

While research about probiotics and antibiotics is still inconclusive, studies suggest that taking probiotics is a safe way to prevent antibiotic-related diarrhea.

Antibiotics can kill the beneficial bacteria in probiotics, so it is advisable to take the two a few hours apart.

After finishing a course of antibiotics, taking a mixture of probiotics can also help to restore balance in the microbiome.

Prebiotics

Prebiotics are food for the beneficial bacteria that live in the gut microbiome.

Feeding the beneficial bacteria before and after taking antibiotics can help to bring balance back to the gut.

Some foods contain low levels of prebiotics, such as:

Manufacturers sometimes add prebiotics to foods, such as:

  • yogurt
  • infant formula
  • cereals
  • bread

Prebiotics may appear on food labels as:

  • galactooligosaccharides, or GOS
  • fructooligosaccharides, or FOS
  • oligofructose, or OF
  • chicory fiber
  • inulin

Most prebiotics are dietary fibers. If a person consumes large quantities, they may experience gas or bloating.

Anyone who is considering adding prebiotics to their diet should do so slowly to allow their gut to adapt.

Fermented foods

Fermented foods are good sources of beneficial bacteria. All fermented foods contain microorganisms, but some heat or filtration processes can kill the beneficial bacteria.

Fermented vegetables, such as sauerkraut or pickles in jars and stored at room temperature, do not contain live cultures.

Microorganisms do not survive any baking processes, so they will not be present in foods such as sourdough bread.

Foods that contain these organisms often have “live and active cultures” on their labels.

Fermented foods include:

  • miso
  • tempeh
  • kimchi
  • yogurt
  • traditional salami
  • some cheeses
  • fresh, sour dill pickles

Vitamin K

Kale is high in vitamin K.

Antibiotics fight all kinds of bacteria, even those that help the body. Some bacteria produce vitamin K, which the body needs to make the blood clot.

To reduce the impact of antibiotics on vitamin K levels, people can eat:

  • kale
  • spinach
  • turnip greens
  • collards
  • Swiss chard
  • parsley
  • mustard greens
  • Brussels sprouts

Fiber

Fiber may stimulate the growth of beneficial bacteria in the gut.

People should avoid high-fiber foods while taking antibiotics, as they may affect how the stomach absorbs the medicine.

However, once a person finishes the full course of antibiotics, eating fiber can help to restore the beneficial bacteria and promote proper digestion.

Foods that are rich in fiber include:

  • artichokes
  • bananas
  • berries
  • beans
  • broccoli
  • lentils
  • nuts
  • peas
  • whole grains

Foods to avoid while taking antibiotics

Some foods interfere with the effectiveness of antibiotics.

These include grapefruits and grapefruit juice, which can stop the body from breaking down and correctly absorbing the medication.

Also, some research indicates that foods fortified with high doses of calcium, such as some orange juices, can interfere with the absorption of certain antibiotics.

Alcohol and antibiotics

Alcohol can interfere with medication.

It is sensible to avoid alcohol while taking any medication. In most cases, moderate drinking will not interfere with antibiotics, but it may make the side effects worse.

A doctor will advise a person not to drink any alcohol if they are taking one of the following antibiotics:

  • Metronidazole, which can treat dental infections, vaginal infections, infected leg ulcers, and pressure sores.
  • Tinidazole, which also treats dental infections, vaginal infections, infected leg ulcers, and pressure sores, and clears bacteria called Helicobacter pylori from the gut.

Drinking alcohol while on one of these antibiotics can cause a serious reaction and the following symptoms:

  • nausea
  • abdominal pain
  • hot flashes
  • a fast or irregular heartbeat
  • headaches
  • dizziness
  • drowsiness

People should avoid alcohol for a further 48 hours after finishing a course of metronidazole and for 72 hours after finishing a course of tinidazole.

Outlook

It is vital to restore a healthful balance in the gut microbiome after taking a course of antibiotics. People can do this by eating probiotics, prebiotics, fermented foods, and fiber.

Probiotics and prebiotics can also help to reduce the side effects of antibiotics.

Some foods can interact with antibiotics, making them less effective. These include grapefruit and foods fortified with high doses of calcium, such as some orange juices.
