Can You Workout on Antibiotics?

Can you workout on antibiotics? You might be surprised to know that you can, but there are a few things you need to take into consideration before hitting the gym.


Before you start working out while taking antibiotics, it is important to understand why antibiotics are prescribed and how they might affect your workout routine. Antibiotics are powerful medications used to treat bacterial infections such as urinary tract infections (UTIs) and respiratory infections. They work by killing or inhibiting the growth of bacteria, which can help relieve symptoms. While it may be tempting to continue with your regular exercise routine while taking antibiotics, it’s important to talk with your doctor first before doing so as there may be risks depending on the type of antibiotic and type of exercise you plan on doing. This guide will provide an overview of some considerations to keep in mind when deciding if it’s safe for you to workout while taking antibiotics.

The Risks of Working Out While on Antibiotics

Working out while on antibiotics can come with a few risks that should be taken into consideration. Antibiotics can interfere with the body’s natural processes and can hamper the progress of a workout. Additionally, there may be a greater risk of developing a side-effect from the drug while exercising. In this article, we will dive into the risks of working out while on antibiotics.

Potential Side Effects

It is important to know the potential side effects of taking antibiotics and working out. Taking antibiotics can cause a decrease in physical endurance, so it may be best to avoid any intensive activities until you have finished your course of medication. If you do choose to exercise while taking antibiotics, it’s important to be aware of the following potential side effects.

Lack of Energy – Antibiotics can make you feel fatigued due to the reduced nutrient absorption, which may make it difficult for you to sustain your workout intensity or duration. To try and counteract this effect, aim for short bouts of low intensity exercises such as walking or light resistance training.

Dehydration – Since antibiotics can reduce water absorption in your body and leave you feeling dehydrated, it may be a good idea to drink more than the recommended amount before, during and after workouts. Try to drink plenty of fluids between sets or throughout your workout routine if sweating is extensive.

Stomach Irritation – Working out on an empty stomach while on antibiotics can cause further stomach upset due to movement and shifting stomach contents around that could irritate your digestive system. Depending on the strength of antibiotic being taken, it might be best to wait a few hours before exercising or opt for lighter activities that still challenge your muscles without too much stress placed on your digestive system such as yoga or Pilates classes.

Reduced Strength and Stamina – Since antibiotics can affect physical endurance levels when working out on them, ensure that you give yourself enough rest periods between sets and increase weights slowly overtime in order not overstretch yourself. If symptoms such as dizziness, nausea or headaches occur whilst impaired with medication please stop exercising and rest off until symptoms have gone entirely before attempting further exercise routines again.

Increased Risk of Injury

Exercising while on antibiotics may put you at an increased risk for injury. Many types of antibiotics can weaken the strength and endurance in your muscles, leaving you shaky and with decreased stability when performing certain exercises. This dramatically increases your risk of falling or otherwise injuring yourself while exercising. Additionally, it can be harder to accurately gauge the intensity level of certain exercises when on such medications, as they can dull pain receptors and make it difficult to perceive how hard you are working your body. It’s important to follow a doctor’s instructions regarding activity levels when taking antibiotics, and obtain permission before returning to a challenging exercise routine or lifting heavy weights.

Alternatives to Working Out

While antibiotics are a necessary part of treating certain infections, they can also take a toll on your energy levels, making it difficult or even dangerous to attempt certain physical activities. There are several alternatives for those who are wanting to stay active while taking antibiotics. Here, we will look at some of these alternatives in depth.

Low Impact Exercises

Working out, particularly physical activity that is at or above a moderate intensity level, is not recommended for those currently taking antibiotics. As an alternative, people can focus on low impact exercises, or activities that are much gentler on the body. Low impact exercise creates minimal, if any, strain on the muscles and joints while allowing you to effectively keep active. Some of the options available include swimming laps in a pool, walking briskly around your neighborhood or hopping on a stationary bike. Other forms of low impact exercise you can explore include Pilates, light weight training and tai chi.

At-home workout DVDs are also an option as they typically feature instructors demonstrating exercises at different levels so that participants can choose options that are suitable for their current fitness level and health needs. For example there may be one video focused more on stretching and yoga positions while another video may emphasize strength building exercises with weights. Having these types of alternatives allow individuals to stay active without overexerting themselves when following doctor prescribed antibiotics treatments.

Relaxation Techniques

It’s certainly true that taking antibiotics can take its toll on both physical and mental health. That said, it’s important to remember that there are some activities you can engage in to help reduce stress, improve your mood, and promote calm throughout your body — even while on antibiotics. Relaxation techniques such as yoga, mindfulness meditation, progressive relaxation, deep breathing exercises and guided imagery can all be helpful in providing relief from the physical and emotional effects of antibiotics.

Yoga is a particularly popular relaxation activity because it promotes flexibility and strength while also encouraging inner reflection. Mindfulness meditation involves focusing on the present moment without judgement or expectation. Progressive relaxation is a great way to reduce muscle tension by consciously tensing and relaxing each body part in sequence. Deep breathing exercises provide an opportunity to connect with your breath in a conscious way that helps facilitate relaxation more quickly. And last but not least, guided imagery encourages visualization of calming images or fantasies in order to relax both the body and mind together.

None of these activities require significant movement or energy expenditure so they are perfect options for someone looking for alternatives to working out while on antibiotics. With regular practice they can also help support recovery after antibiotics by reducing stress levels which may speed up healing time considerably!


Ultimately, the safety of working out while on antibiotics depends on your overall health situation and the complexity of your antibiotics. Working out while on antibiotics can be risky if there are further complications involved, so it’s best to consult your doctor before doing so. If you aren’t experiencing severe side effects and your doctor gives you clearance, then you should be able to work out in moderation while on antibiotics. As always, it’s important to stay hydrated and listen to your body during exercise – especially when taking medication.
