Antibiotics have saved millions of lives since their discovery, helping people recover from bacterial infections that were once life-threatening. For older adults, antibiotics can be especially important because aging can bring changes to the immune system and an increased risk of certain infections. However, using antibiotics correctly is just as important as having access to them.

In recognition of U.S. Antibiotic Awareness Week,  FirstLantic Healthcare is sharing important information to help seniors and their families understand when antibiotics are necessary, how to use them safely, and why preventing antibiotic resistance matters.

1. Understanding What Antibiotics Can and Cannot Treat

Antibiotics are medications designed to fight bacterial infections. They may be prescribed for conditions such as bacterial pneumonia, certain urinary tract infections (UTIs), and some skin infections. However, antibiotics do not work against viruses. That means they will not help treat illnesses such as:

  • The common cold

  • Influenza (flu)

  • COVID-19

  • Most sore throats

  • Most cases of acute bronchitis

Taking antibiotics when they are not needed can cause unnecessary side effects and contribute to antibiotic resistance. Seniors should always consult their healthcare provider to determine whether an antibiotic is appropriate.

2. Why Antibiotic Awareness Is Especially Important for Seniors

As we age, our bodies undergo changes that can affect how we respond to infections and medications. Older adults may also have chronic health conditions, such as diabetes, heart disease, or kidney disease, that complicate treatment. Seniors may be more vulnerable to antibiotic-related complications because they often take multiple medications, increasing the possibility of drug interactions. Additionally, older adults are at greater risk of developing Clostridioides difficile (C. diff), a potentially serious infection that causes diarrhea and inflammation of the colon. Antibiotic use can increase this risk by disrupting healthy bacteria in the digestive system. Understanding these risks helps seniors and caregivers make informed healthcare decisions.

3. The Growing Concern About Antibiotic Resistance

Antibiotic resistance occurs when bacteria develop the ability to survive medications that once killed them. According to the Centers for Disease Control and Prevention (CDC), antimicrobial resistance is a major public health concern. When bacteria become resistant to antibiotics, infections may become harder to treat, requiring longer hospital stays, more expensive medications, or additional medical care. Older adults can help combat antibiotic resistance by using antibiotics only when medically necessary and following their healthcare provider’s instructions.

4. Five Tips for Using Antibiotics Safely

If a healthcare provider prescribes antibiotics, these five tips can help seniors use them responsibly.

1. Take antibiotics exactly as prescribed. Follow the recommended dosage, timing, and duration. Do not stop early or extend treatment without consulting your healthcare provider.

2. Never share antibiotics. A medication prescribed for one person may be inappropriate or dangerous for another.

3. Avoid saving leftover antibiotics. Do not keep unused antibiotics for future illnesses. Ask your pharmacist about safe disposal options.

4. Discuss potential interactions. Seniors taking medications for blood pressure, heart conditions, diabetes, or other health concerns should ask their doctor or pharmacist about possible interactions.

5. Watch for side effects. Common side effects can include nausea, diarrhea, and stomach discomfort. Severe diarrhea, allergic reactions, or unusual symptoms should be reported promptly. Difficulty breathing or swelling of the face or throat requires emergency medical attention.

5. Preventing Infections Before Antibiotics Are Needed

One of the best ways to reduce unnecessary antibiotic use is to prevent infections in the first place.

Seniors can lower their risk by practicing healthy habits, including:

  • Washing hands frequently: Proper handwashing helps prevent the spread of bacteria and viruses.

  • Staying current on vaccinations: Recommended flu, pneumonia, COVID-19, and other vaccinations can help protect older adults from serious illnesses.

  • Practicing good food safety: Proper food handling and storage reduce the risk of foodborne infections.

  • Maintaining good personal hygiene: Regular bathing, oral care, and appropriate wound care can help prevent infections.

  • Managing chronic conditions: Keeping diabetes and other health conditions under control may reduce infection-related complications.

  • Staying physically active and eating well: Healthy lifestyle habits support overall immune function.

6. Understanding Antibiotics and Urinary Tract Infections

Urinary tract infections are a common concern among older adults, but not every positive urine test means antibiotics are necessary. Some seniors have bacteria in their urine without experiencing symptoms. This condition, known as asymptomatic bacteriuria, generally does not require antibiotic treatment, except in certain circumstances.

Symptoms of a UTI may include burning during urination, frequent urination, pelvic discomfort, or fever. Sudden confusion in an older adult warrants medical evaluation, but confusion alone does not establish that a UTI is present. Caregivers should avoid assuming that every change in behavior or urine appearance indicates an infection. Proper medical evaluation can help prevent unnecessary antibiotic prescriptions.

7. How Family Members and Caregivers Can Help

Family caregivers and professional home health aides can play an important role in helping seniors manage medications safely. They can assist by reminding seniors when medications are due, observing possible side effects, keeping an updated medication list, and communicating concerns to healthcare professionals.

Caregivers can also encourage seniors to ask questions before starting a new antibiotic, including:

  • Is this infection bacterial or viral?

  • Do I definitely need an antibiotic?

  • What side effects should I watch for?

  • Will this antibiotic interact with my current medications?

  • When should I expect to feel better?

These simple conversations can help prevent medication errors and encourage safer treatment.
