Antibiotics are used to treat a variety of bacterial infections. Examples of bacterial infections include ear infections, skin infections, sinus infections, urinary tract infections, and some respiratory infections. Since antibiotics are frequently prescribed medications for infections, you may be wondering: can you buy antibiotics over the counter? The answer is no. Under federal law, all antibiotics require a prescription from a health care provider.

Why do antibiotics require a prescription?

Antibiotics require a prescription for three main reasons. First, each time an antibiotic is used, there is a risk of developing antibiotic resistance for future infections. Second, antibiotics require a prescription due to the risk of potential side effects. Third, if you take the wrong antibiotic or take one when it’s not needed, an infection may worsen or you could experience an allergic reaction.

What is antibiotic resistance?

Antibiotic resistance refers to a situation where bacteria do not respond to the drugs that are designed to kill them. Bacteria can and do evolve. If antibiotic resistance takes root, simple infections can become potentially life-threatening. Antibiotic stewardship, or the way the drugs are prescribed or used, is critical to ensure that antibiotic resistance doesn’t develop.

The potential for overusing or misusing antibiotics, if they were available over the counter, could lead to the evolution of superbugs, which could be challenging to treat.

Can you buy antibiotics over the counter?

No, you cannot buy antibiotics over the counter. Your health care provider must write you a prescription to get filled at the pharmacy. Be sure you shop around for the price of your antibiotic, before filling and paying for it.

Commonly Prescribed Antibiotics

There are more than 100 types of antibiotics. Each antibiotic is designed to be effective against specific bacteria. Your health care provider will determine the most likely type of bacteria causing your infection and prescribe the appropriate antibiotic to stop the growth of the bacteria.

Some antibiotics may be effective against all of the potential types of bacteria responsible for your infection, which is why some antibiotics are prescribed more frequently than others. The 10 most commonly prescribed antibiotics can fight a variety of bacterial infections.
