According to the CDC, respiratory tract infections, particularly in outpatient settings, are the most common reason for antibiotic use. A significant issue, however, is that most of these infections are viral, meaning antibiotics are ineffective against them. This widespread, and often unnecessary, use contributes significantly to the global public health threat of antibiotic resistance.

Over 90% of upper respiratory infections (URIs) are caused by viruses, which antibiotics like cephalexin cannot treat. This makes knowing whether an infection is viral or bacterial crucial for proper treatment and avoiding antibiotic misuse, which is a major contributor to antibiotic resistance.

According to MedlinePlus, cephalexin is used to treat bacterial respiratory infections such as pneumonia. However, it is crucial to understand that antibiotics like cephalexin are ineffective against viral causes, which are responsible for most common chest infections.

According to the CDC, at least 28% of antibiotics prescribed in outpatient settings are unnecessary [1.6.1]. Understanding **what happens if you take antibiotics with a virus** is key to grasping why this is a major public health issue, as they are ineffective and cause harm [1.2.2, 1.2.5].

According to the CDC, antibiotics are ineffective against viruses and do not treat viral infections like the common cold or flu. This fundamental biological truth explains precisely why viruses have no reaction to antibiotics and underscores the critical importance of proper antimicrobial stewardship.

According to the CDC, about one-third of antibiotic use in people is not needed or appropriate [1.3.3]. This statistic highlights a critical question: how often is too much to take antibiotics, and what are the consequences of overuse? [1.3.3]

According to the CDC, at least 28% of antibiotics prescribed in outpatient settings are unnecessary [1.10.1]. This raises a common question: Is amoxicillin good for fever? While it can help if the fever is from a bacterial infection, it's ineffective against viruses [1.2.2, 1.2.3].

While many people search for **over the counter antiviral drugs**, the vast majority of effective antiviral treatments, including those for influenza and COVID-19, are only available with a prescription. However, a few specific topical antiviral options do exist for minor viral issues like cold sores. This guide explores which antiviral drugs are available over-the-counter and why others require a doctor's supervision.

While most potent antiviral medications require a prescription, a 2018 review noted that a topical cream containing docosanol can be a marginally more effective over the counter antiviral medication than a placebo for treating cold sores. This topical cream is the only FDA-approved, non-prescription product that directly inhibits viral replication. For other common viral infections like the flu or COVID-19, over-the-counter products are only available for symptom management, not for fighting the virus itself.

Unlike antibiotics, which can target a range of bacteria, each antiviral is specifically designed to combat only one or a few particular viruses. This selectivity defines what do antivirals do to your system to treat specific viral infections like flu, herpes, and HIV.
