Amoxicillin, while generally safe, can cause side effects. The most common include diarrhea, nausea, and vomiting. These are usually mild and resolve without treatment. However, severe diarrhea, especially if bloody or watery, requires immediate medical attention, as it could indicate a serious intestinal infection like *Clostridium difficile*.
Skin rashes are another possibility. Most are mild, but a serious allergic reaction (anaphylaxis) is a rare but life-threatening complication. This involves swelling of the face, lips, tongue, or throat, difficulty breathing, and a rapid heartbeat. Call emergency services immediately if you experience these symptoms.
Less common side effects include thrush (a fungal infection of the mouth), changes in urine color, and headache. Persistent or worsening symptoms warrant a call to your doctor. If you develop any new or concerning symptoms while taking amoxicillin, contact your healthcare provider for guidance.
Remember to always follow your doctor’s instructions regarding dosage and duration of treatment. Don’t stop taking amoxicillin without consulting your doctor, even if you feel better.
