Can You Take Amoxicillin for a Cold?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
No, amoxicillin should not be used for a cold because colds are caused by viruses, not bacteria. Amoxicillin is an antibiotic that only fights bacterial infections and has no effect on viral illnesses. Taking antibiotics unnecessarily can lead to antibiotic resistance and unwanted side effects like nausea or diarrhea. The CDC reports that about 30% of antibiotic prescriptions are unnecessary, often for viral conditions like colds. Cold symptoms typically resolve on their own within 7-10 days with rest, fluids, and over-the-counter medications for symptom relief. If your cold symptoms worsen or persist beyond 10 days, consult a healthcare provider to rule out secondary bacterial infections.
