Why Can’T You Take Antibiotics With Steroid Injection

Antibiotics are a vital part of modern medicine, and they’re often prescribed to people who are sick. But what many people don’t know is that antibiotics can also be taken together with steroid injections. This combination is often used to treat sports injuries and other complaints that don’t respond to other treatments. But there are a few reasons why this combination can be risky—particularly for those who take antibiotics regularly. In this blog post, we’ll explore the risks of taking antibiotics and steroid injections together, and provide some tips on how to minimize the potential harm.

What are Antibiotics?

Antibiotics are medicines that fight infections. They are effective against bacteria, viruses, and some protozoa. Antibiotics can be taken by mouth, injection, or IV.

Many people think you can’t take antibiotics with steroid injections because of the potential for antibiotic resistance. However, this is not always true. There are specific antibiotics that can be taken together with steroid injections with no risk of resistance. In fact, taking these antibiotics before and after a steroid injection may even help to treat the inflammation caused by the injection!

Types of Antibiotics

There are a few different types of antibiotics, each with its own purpose and side effects. Penicillin is the most common antibiotic and is effective against a wide range of bacteria. However, it can cause serious side effects if taken incorrectly, including kidney failure.

Cephalosporins are another type of antibiotic that is widely used. They are more resistant to bacterial resistance than penicillin, but can also have serious side effects, such as heart failure and seizures.

Vancomycin is a last resort antibiotic and is only effective against a few types of bacteria. It can be dangerous if taken incorrectly, leading to diarrhea, liver damage, and even death.

How Do Antibiotics Work?

Antibiotics work by killing the bacteria. They do this by breaking down the cell walls of the bacteria. This destroys the bacteria and makes it unable to reproduce.

When Should You Not Take Antibiotics?

There are various reasons why antibiotics may not be effective when taken with steroid injections. For example, the antibiotic could bind to the steroid and not reach its target. Additionally, the antibiotic could speed up the breakdown of the steroid, leading to a decrease in its effectiveness. If you’re taking antibiotics along with a steroid injection, be sure to speak with your doctor about what steps should be taken to ensure optimal results.

Side Effects of Taking Antibiotics with Steroid Injection

There are a few potential side effects of taking antibiotics with steroid injection, including infection and allergic reactions. If you experience any side effects from taking antibiotics and steroid injection, stop taking the medication and consult with your doctor. In addition, be sure to tell your healthcare provider if you are taking any other medications or supplements, as they may interact with antibiotic treatment.


If you are scheduled to receive an injection of steroids, it is important to understand that antibiotics may not be a good idea. Antibiotics can interfere with the effectiveness of the steroid injection, and this could lead to a number of unwanted side effects. If you are unsure whether or not antibiotics will interfere with your steroid injection, please consult with your doctor before proceeding.
