Antibiotics do not fight infections caused by viruses like colds, flu, most sore throats, bronchitis, and many sinus and ear infections. Instead, symptom relief might be the best treatment option for viral infections.
Get smart about when antibiotics are needed—to fight bacterial infections. When you use antibiotics appropriately, you do the best for your health, your family's health, and the health of those around you.
Taking antibiotics for viral infections, such as colds, flu, most sore throats, bronchitis, and many sinus or ear infections:
- Will not cure the infection
- Will not keep other people from getting sick
- Will not help you or your child feel better
- May cause unnecessary and harmful side effects
- May contribute to antibiotic resistance, which is when bacteria are able to resist the effects of an antibiotic and continue to cause harm
Rest, fluids, and over-the-counter products may be your or your child's best treatment option against viral infections.
Use Antibiotics Wisely
Remember–there are potential risks when taking any prescription drug. Unneeded antibiotics may lead to harmful side effects and future antibiotic-resistant infections.
