Amoxicillin, while generally safe and effective, can cause side effects. These are usually mild but require attention. The most common are gastrointestinal issues.
Gastrointestinal Side Effects
- Diarrhea: This is frequently reported. If it’s severe or persistent, contact your doctor. Nausea: Some individuals experience nausea, which may improve with food intake or adjustments to medication timing. Vomiting: This is less common than diarrhea or nausea, but warrants attention if it becomes frequent or severe. Abdominal pain or cramps: These are occasionally reported and may respond to over-the-counter antacids.
Beyond digestive issues, other less frequent side effects can occur:
Other Potential Side Effects
Skin rash: A rash can be a sign of an allergic reaction. Stop taking amoxicillin immediately and contact your doctor if a rash develops. Yeast infections (thrush): Amoxicillin can disrupt the natural balance of bacteria in the body, leading to yeast overgrowth. This often manifests as oral thrush (white patches in the mouth) or vaginal yeast infections. Headache: Headaches are a possibility, typically mild and self-limiting. Dizziness: Though uncommon, dizziness can occur. Avoid driving or operating machinery if affected.
Serious side effects are rare, but seek immediate medical attention if you experience: severe allergic reactions (difficulty breathing, swelling of the face, lips, or tongue), seizures, or unusual bleeding or bruising.
Always discuss potential side effects with your doctor before starting any medication. They can provide personalized advice based on your medical history and condition.
