Amoxicillin, while generally safe, can cause several side effects. The most common include diarrhea, nausea, and vomiting. These are usually mild and resolve without treatment. However, severe diarrhea could indicate Clostridium difficile infection, so contact your doctor immediately if it occurs.
Less Common Side Effects
Less frequent, but still possible, side effects include skin rashes, itching, and hives. These allergic reactions can range in severity, from mild discomfort to a life-threatening condition called anaphylaxis. Anaphylaxis requires immediate medical attention. Seek help immediately if you experience difficulty breathing, swelling of the face, lips, or tongue, or a sudden drop in blood pressure following amoxicillin use.
Other potential side effects, though rare, include changes in blood cell counts (which your doctor will monitor through blood tests), yeast infections (particularly in women), and increased risk of seizures in individuals with certain predispositions. Your doctor should be informed of any pre-existing medical conditions before starting amoxicillin.
Medication Interactions
Amoxicillin can interact with other medications. For example, it can reduce the effectiveness of birth control pills. Always inform your doctor and pharmacist of all medications, supplements, and herbal remedies you’re taking before starting amoxicillin.
