Antibiotic Stewardship: Guide to Using Antibiotics Correctly

Posted on November 9th, 2026

A sore throat, lingering cough, or uncomfortable infection can leave you wanting relief as quickly as possible. It is understandable to wonder whether an antibiotic would help. The answer depends on what is causing your symptoms—and which treatment fits that diagnosis.

At Washington Wellness in Phoenix, compassionate care and patient education go together. Understanding antibiotic stewardship can help you have a more informed conversation about your symptoms, treatment options, and recovery.

What Is Antibiotic Stewardship?

Antibiotic stewardship means improving how antibiotics are prescribed and used. The goal is to treat bacterial infections effectively while reducing avoidable side effects and antibiotic resistance.

The CDC’s antibiotic stewardship framework emphasizes appropriate prescribing to improve patient safety and outcomes. For patients, this means understanding whether an antibiotic is needed and, when it is, following the prescribed medication, dose, and treatment duration.

A prescription should have a clear purpose. Taking an antibiotic simply because it helped during a previous illness can expose you to risks without treating your current problem.

Why Evidence-Based Treatment Starts With an Exam

Evidence-based care combines research and clinical guidance with a clinician’s assessment of your individual needs. Before choosing treatment, your provider considers your symptoms, examination findings, medical history, and any relevant test results.

Different antibiotics work against different bacteria. When appropriate, a culture can help identify the organism causing an infection, while susceptibility testing helps determine which medication is likely to work. MedlinePlus explains how antibiotic sensitivity testing guides treatment.

Testing is not necessary for every illness. Its value depends on the suspected infection and the clinical situation. The aim is to gather the information needed for a treatment decision, rather than assume that similar symptoms always have the same cause.

Different Bacterial Infections Need Different Antibiotics

An antibiotic used for one infection may be unsuitable for another. The CDC’s outpatient treatment recommendations illustrate how treatment varies:

Diagnosed condition	Examples a clinician may consider	Important distinction
Confirmed group A strep throat	Penicillin or amoxicillin	Most sore throats are not strep; testing helps establish the diagnosis when indicated.
Acute bacterial sinusitis	Amoxicillin or amoxicillin/clavulanate	Many sinus infections are viral. Some uncomplicated cases can be monitored with reliable follow-up.
Uncomplicated bladder infection in otherwise healthy, nonpregnant premenopausal women	Nitrofurantoin or fosfomycin	These examples apply to a specific patient group, not every urinary infection.

These are educational examples, not instructions for choosing your own medication. Your clinician must assess whether an option is appropriate for you, including your allergy history and other health considerations.

Ask why a particular antibiotic was selected and how you should take it. Understanding the reason behind your prescription can make following the plan easier.

Why Antibiotics Do Not Treat Viruses

Antibiotics act on bacteria, killing them or interfering with their ability to grow. Viruses are different organisms, so antibacterial medicines do not treat viral infections.

As the FDA explains in its guide to appropriate antibiotic use, antibiotics do not treat the common cold, influenza, or COVID-19. Taking one for a viral illness will not address its cause.

If an antibiotic is not recommended, ask what can help with your symptoms, what recovery may look like, and when you should be reassessed. You should still leave the visit with a clear care plan and an opportunity to ask questions.

Antibiotic Overuse and C. diff: Understanding the Connection

Antibiotics can affect helpful bacteria in your gut as well as bacteria causing an infection. This disruption can allow Clostridioides difficile, commonly called C. diff, to grow and cause illness.

According to the CDC’s information about C. diff, the infection can cause diarrhea and inflammation of the colon. Symptoms may also include fever, abdominal pain, and nausea.

C. diff risk is not limited to antibiotic overuse: even a necessary course can increase risk. Avoiding unnecessary prescriptions reduces exposure that offers no medical benefit.

If you develop diarrhea during or after antibiotic treatment, contact a healthcare professional. Not all antibiotic-associated diarrhea is C. diff, but it deserves assessment. Tell your provider which antibiotic you took and when you took it.

How Unnecessary Antibiotics Contribute to Resistance

Antibiotic resistance develops when bacteria become able to withstand medicines intended to treat them. The bacteria become resistant; your body does not become “immune” to antibiotics.

The World Health Organization identifies misuse and overuse as major drivers of antimicrobial resistance. Resistant infections can be harder to treat and may leave fewer effective treatment options.

Using antibiotics appropriately helps protect their usefulness for you and others who may need them in the future.

Use Your Prescription Safely

When an antibiotic is appropriate, its benefits generally outweigh its risks. The CDC’s antibiotic safety guidance recommends taking it exactly as prescribed and discussing side effects with a healthcare professional.

Keep these habits in mind:

• Follow the instructions for your dose, timing, and treatment duration.

• Do not share antibiotics or take someone else’s prescription.

• Do not save leftover antibiotics to treat a future illness.

• Ask your prescriber or pharmacist about questions, side effects, or difficulty taking the medication.

Helpful questions at your appointment include: “Why is this medication right for my infection?” and “When should I contact you if I am not improving?”

When Treatment May Include a Small Procedure

Some infections require care beyond a prescription. For example, a skin abscess is a collection of pus that may need professional drainage. The Infectious Diseases Society of America’s skin infection guidelines recommend incision and drainage for appropriate abscesses; the clinician also assesses whether antibiotics are needed.

Washington Wellness’s Exams and Small Procedures service includes wound care and incision and drainage for abscesses. An assessment helps determine which approach is appropriate for your concern and whether further care is needed.
