Common medicines that affect gut bacteria

You may be surprised to learn that some prescription drugs affect the balance of your gut microbiome. These medicines can have an effect on the balance of your gut bacteria, but do you know the dangers associated with them? Listed below are some of the most common drugs that can affect your gut bacteria. They can affect your overall health and even cure disease. Some of the side effects of these medicines may be harmful, but they are rarely known by the doctors.


There are several reasons why common medicines can affect the gut microbiome. These interactions occur through biotransformation, in which the body changes the available form of a drug to one that affects the gut. In the past, researchers have focused on antibiotics as one of the most common drugs that can alter the gut microbiome. Today, however, we are learning more about a variety of drugs and their effects on the gut microbiome.


Several studies have found that common drugs can alter the gut microbiome. Some of these drugs can increase antimicrobial resistance, increase the risk of gut disorders and bacterial infections, and may even cause obesity. Other common medicines affect the gut bacteria, including proton pump inhibitors, laxatives, and metformin. Here are the major effects of common medications. Learn more about the effects of these medications on your gut microbiome.


If you’re taking corticosteroids to treat an inflammatory disease, it’s important to know that these drugs can have some adverse side effects. Corticosteroids are common medicines that alter gut bacteria. These medications suppress the immune system and can reduce inflammation. They can also be used to prevent organ rejection in people undergoing organ transplants. They are also used to relieve pain and inflammation associated with chronic conditions, such as asthma or croup. They’re also commonly used to prevent pain and inflammation following eye surgery.

H2 blockers

H2 blockers, also known as aprotinin inhibitors, are common medicines that affect gut bacteria. They can be purchased over-the-counter at pharmacies and are marketed as relief for heartburn, indigestion, and excess stomach acid. Although H2 blockers are generally considered safe, they should be taken under the guidance of a health care provider. Some patients may need to take them regularly, while others should only take them when necessary.

ACE inhibitors

Researchers have found that ACE inhibitors weaken the immune system and increase the risk of infection. While they are commonly used to treat high blood pressure and heart failure, they can also affect the gut bacteria. They found that ACE inhibitors decreased the activity of an enzyme that is needed to fight bacteria. These enzymes are made by neutrophils. The study looked at mice that had damaged heart valves and were more likely to get an infection with MRSA. The researchers found that losartan did not weaken the neutrophil’s ability to fight bacteria.


Among the many commonly prescribed medicines, clindamycin has a reputation for disrupting the gut microbiome. Though this antibiotic is generally used to treat recurrent strep infections, it can also affect the gut bacteria. Studies have shown that this medication can lead to colonization of C. difficile, even in small amounts. This is potentially harmful and can lead to excessive diarrhea and colitis.


Cipro is a type of antibiotic, which means that it affects the balance of the gut bacteria. It has a number of side effects, ranging from mild to severe. It should not be used by people who are pregnant or breastfeeding. In some cases, it may cause nausea and vomiting, or it may increase the risk of heart disease. It is important to speak to your doctor about your risk of developing these side effects.
