When do you need antibiotics?

Why Antibiotics Aren’t Always the Answer

When you’re sick, it’s natural to want a quick fix, and many people assume antibiotics are the solution. While antibiotics can be lifesaving when used appropriately, they don’t work for every illness. In fact, using them when they aren’t needed can sometimes do more harm than good.

Antibiotics only treat infections caused by bacteria. Many common illnesses seen in urgent care—such as colds, flu, most sore throats, bronchitis, and early sinus infections—are caused by viruses. Taking antibiotics for a viral infection won’t shorten how long you’re sick or make symptoms resolve faster.

Using antibiotics unnecessarily can lead to side effects like stomach upset, diarrhea, allergic reactions, and yeast infections. Over time, repeated or inappropriate use also contributes to antibiotic resistance, making future bacterial infections harder to treat—not just for you, but for the community as a whole.

There are situations where antibiotics are absolutely the right choice. Certain ear infections, bacterial pneumonia, strep throat, urinary tract infections, and prolonged or worsening sinus infections may require antibiotic treatment. The challenge is that symptoms can overlap, which is why a medical evaluation is important before deciding on treatment.

At our clinic, the goal is always to treat you effectively and safely. That sometimes means prescribing antibiotics—and other times it means focusing on symptom relief, close follow-up, and letting your body do what it’s designed to do. When antibiotics aren’t recommended, it’s not because your illness isn’t taken seriously—it’s because the safest and best care is being prioritized.
