Antibiotics are powerful medications that fight bacterial infections: think strep throat, UTIs, and some skin issues. But in the U.S., most antibiotics require a prescription — and for good reason. Using the wrong one (or using it too often) can lead to antibiotic resistance, when bacteria learn to outsmart the medications meant to kill them.
Still, some over-the-counter (OTC) antibiotics exist, such as topical Neosporin in your local drugstore. But for anything beyond a surface-level treatment, it may be best to get an antibiotic prescription from a licensed healthcare provider.
Antibiotics are medications that help treat bacterial infections. They kill bacteria or make it difficult for the bacteria to multiply. You can take antibiotics orally via capsules, pills, or liquids — or apply them topically using sprays, ointments, or eye or ear drops. Severe infections are sometimes treated intravenously (by IV).
Antibiotics can treat things like:
However, antibiotics are not effective for treating viral infections like colds and the flu.
Over-the-counter antibiotics are medications you can purchase without a doctor’s prescription, either at a local drugstore or online.
While you can’t request prescription-strength oral antibiotics over the counter (this isn’t approved in the United States), there are some OTC topical antibiotics available for purchase without a prescription.
Examples of topical antibiotics available for purchase over the counter include:
However, oral antibiotics require a prescription by a licensed healthcare provider in the United States.
You can use over-the-counter topical antibiotics for things like:
OTC topical antibiotics help prevent or treat infections within the skin by inhibiting bacterial growth.
Prescribed antibiotics are oral or topical medicines that help treat infections. They’re prescribed by a licensed healthcare provider for various conditions and are a common type of prescription medication. Infect, healthcare practitioners in the U.S. wrote more than 211 million prescriptions for oral antibiotics for patients not staying in hospitals (outpatients).
Many types of antibiotics require a prescription, but not all. Oral antibiotics in the U.S. require a prescription, while some topical antibiotics do not.
Examples of commonly prescribed antibiotics include:
Penicillins are the most commonly prescribed antibiotics.
Use prescribed antibiotics anytime your healthcare provider suggests these medications to treat a bacterial infection. However, antibiotics aren’t always necessary. Sometimes the body can clear an infection on its own. Your provider determines which medicines are best for you.
According to the Centers for Disease Control and Prevention (CDC), at least one-third of antibiotic medications prescribed to pediatric patients (babies, children, and teenagers) aren’t necessary.
Here are some differences between OTC and prescription antibiotics
OTC | Prescription | |
Efficacy | Effective for topical skin concerns | Effective for most infections when used as prescribed |
Scope | Topical antibiotics only | Topical and oral medications available |
Side effects | Varies; typically minor | May be more severe (diarrhea, etc.) |
Convenience | Easily accessible at pharmacies and online | Requires a prescription from a licensed healthcare provider |
Monitoring | No medical appointment required | Requires evaluation and monitoring by a licensed healthcare professional |
Cost | Typically cheaper | May be cheap or free with health insurance |
Potency | Less potent | Usually more potent |
There’s no one-size-fits-all approach when choosing OTC vs prescription antibiotics, as individualized needs vary from person to person.
Signs of a bacterial infection that may warrant prescription antibiotics include:
See a healthcare provider anytime you develop new or unusual symptoms that don’t resolve on their own or are severe.
