Amoxicillin treats bacterial infections, not viruses. Therefore, antibiotics are only necessary for coughs caused by bacterial infections, a relatively uncommon cause of coughs. Most coughs result from viral infections like the common cold or influenza.
Identifying a Bacterial Cough
A cough lasting more than three weeks might indicate a bacterial infection. Look for additional symptoms such as: thick, discolored (yellow-green or brownish) mucus, high fever (101°F or higher), chest pain, and shortness of breath. These symptoms suggest a possible bacterial infection like bronchitis or pneumonia. However, a doctor’s diagnosis is crucial.
When to See a Doctor
Seek medical attention if your cough is severe, persistent (lasting longer than two weeks), accompanied by high fever, or if you experience difficulty breathing. A doctor will evaluate your symptoms, possibly conduct tests (like a chest X-ray), and determine the appropriate treatment. Amoxicillin might be prescribed if a bacterial infection is confirmed, but this isn’t always the case. Many coughs improve with rest and supportive care.
Treating Viral Coughs
Viral coughs usually resolve on their own within a few weeks. Focus on symptom management: drink plenty of fluids, get plenty of rest, and use over-the-counter cough suppressants or expectorants as needed, always following the instructions on the label. Avoid smoking and exposure to irritants like dust or smoke, as these can worsen cough symptoms.
