Respiratory Infections – What to Know and How to Treat

If your chest feels tight or a cough won’t quit, chances are you’re dealing with a respiratory infection. These bugs range from the common cold to serious pneumonia, but they all share a few tell‑tale signs: sore throat, runny nose, fever, and shortness of breath.

Common Types and When to Worry

The most frequent culprits are viruses that cause colds and flu. They usually clear up on their own within a week or two. Bacterial infections like bronchitis or pneumonia show up when you have high fever, chest pain, or thick mucus that doesn’t improve.

If you notice wheezing, rapid breathing, or your symptoms linger past ten days, it’s time to get checked. People with asthma or COPD should be extra cautious because an infection can trigger a flare‑up.

Treatment Options That Work

Most viral infections just need rest, fluids, and over‑the‑counter meds for fever or aches. Antibiotics only help when bacteria are the problem. For example, Flagyl ER (metronidazole) is effective against certain bacterial lung infections but won’t touch a virus.

When asthma or COPD gets involved, inhalers become key. Switching from one inhaler to another—like moving from Symbicort to Advair—can improve control if your current device isn’t covering symptoms. Our step‑by‑step guide walks you through tapering doses and talking to your doctor about the change.

If you rely on a rescue inhaler like ProAir, knowing alternatives is handy. Options such as Accuneb or generic albuterol give similar relief with different dosing schedules, so you can pick what fits your lifestyle.

Beyond meds, simple habits cut down infection risk: wash hands often, avoid close contact when others are sick, and keep up with flu shots. Staying hydrated helps thin mucus, making it easier to clear.

Bottom line: recognize the signs early, use the right treatment—antibiotics for bacterial cases, inhalers for asthma flares—and don’t ignore persistent or worsening symptoms. Quick action keeps a nasty infection from turning into something serious.
