Antibiotics are medications used to treat bacterial infections. Although antibiotics can be very effective in treating infections, their use has caused some major problems. When bacteria are treated with an antibiotic, the bacteria may become resistant to that antibiotic. This means that a small number of organisms that are not killed by the antibiotic survive and make more organisms. The chance of bacteria becoming resistant is greater if the antibiotic is used when it is not necessary, or when it is not taken for the proper length of time. Because of resistance, some common infections must be treated with newer, more expensive antibiotics. More and more common infections are becoming almost untreatable.

Many common infections, especially colds and other upper respiratory infections, are caused by viruses. These infections should not be treated with antibiotics! If your health care provider does not feel you need an antibiotic, don't pressure your provider to prescribe one.

In general, antibiotics are very safe and effective if taken properly. Make sure you tell your provider and pharmacist what medications you are allergic to, and what side effects you have had in the past. Make sure that you understand the directions for the antibiotic. Taking the antibiotic the right way not only improves the chance of your infection going away, it reduces the chance that bacteria will become resistant. Make sure you finish all the medication, even if you are feeling better. Don't take antibiotics unless prescribed for you by a healthcare provider. Don't use leftover or someone else's antibiotics!

There are many different types of antibiotics, and there can be different types of side effects. The most common include upset stomach, diarrhea and skin rashes. If you develop an upset stomach or diarrhea, ask your pharmacist if you can take the antibiotic with food. If you develop diarrhea or a skin rash, call your provider. If you do develop a side effect, don't just stop taking the antibiotic. Call your provider to see what alternatives are available to treat your infection.

If you have questions about these medications, do not wait! Ask your healthcare provider or pharmacist.
