Did you know that taking antibiotics when you or your child has a viral infection can do more harm than good?
According to the U.S. Centers for Disease Control and Prevention, when it comes to children, antibiotics are the most common reason for emergency room admissions due to drug side effects.
Bed rest, drinking plenty of fluids and using over-the-counter medications are the preferred treatment options for viral infections, says the CDC.
Colds and other upper respiratory tract infections, as well as some ear infections, can be caused by viruses, not bacteria. Antibiotics only work on bacteria, not viruses.
Antibiotics are the most important tool in the fight against life-threatening bacterial infections, yet resistance to these drugs is also one of the most pressing public health problems, the CDC says.
The agency urges people not to take antibiotics for viral infections.
For example, colds, sore throats, acute bronchitis, middle ear infections and sinus infections are mostly caused by viruses. Therefore, when taking antibiotics, what will most likely happen is that:
- Infections will not be cured.
- You or your child will not feel better.
- You or your child may experience harmful side effects.
Most cases of antibiotic resistance occur when patients are prescribed antibiotics for specific conditions and then start taking them inappropriately or incorrectly. So if you are prescribed antibiotics, you should not miss doses.
If you or your child has an upper respiratory infection, you should:
- Ask your doctor or pharmacist about over-the-counter medications that may provide relief.
- Drink plenty of fluids and get plenty of rest.
