Contact your doctor immediately if you experience a severe allergic reaction. Symptoms include difficulty breathing, swelling of your face, lips, tongue, or throat, and hives. These reactions require immediate medical attention.
Don’t delay seeking help if your symptoms worsen or don’t improve after a few days. Amoxicillin typically starts working within 24-48 hours. If you notice no improvement in your condition after this timeframe, it’s crucial to contact your physician. This includes persistent or worsening cough, fever, pain, or skin issues.
Signs of Serious Side Effects
Seek medical advice if you develop any of the following:
| Severe diarrhea | Watery stools, possibly containing blood or mucus, that persist for more than 24 hours. This could indicate Clostridium difficile infection. |
| Jaundice | Yellowing of the skin or whites of your eyes; sign of liver problems. |
| Dark urine | Unusual darkening of urine, potentially indicating liver or kidney issues. |
| Unusual bleeding or bruising | This may suggest a problem with blood clotting. |
When to Monitor for Specific Issues
Monitor for any new or worsening symptoms, particularly those not initially treated with amoxicillin. For instance, if you are taking amoxicillin for a respiratory infection and develop new abdominal pain, consult your doctor immediately. Always inform your physician of any pre-existing conditions before starting antibiotic treatment.
