Cefadroxil, while generally well-tolerated, can cause side effects. These are usually mild and temporary, but you should contact your doctor if they persist or worsen.
- Gastrointestinal Issues: Expect some people to experience diarrhea, nausea, or vomiting. These are usually manageable and resolve on their own. Drink plenty of fluids to stay hydrated. Allergies: A rash, itching, or hives are possible allergic reactions. Stop taking Cefadroxil and seek immediate medical attention if you experience these symptoms. Severe allergic reactions are rare but require immediate treatment. Other Potential Side Effects: Less common side effects include headache, dizziness, vaginal yeast infection, and changes in your urine color (darker urine).
Drug interactions can occur. Always inform your doctor about all medications you are currently taking, including over-the-counter drugs, herbal supplements, and vitamins. Certain medications can affect how Cefadroxil works or increase the risk of side effects.
- Warfarin: Cefadroxil may interact with blood thinners like warfarin, potentially increasing bleeding risk. Close monitoring of your blood clotting time may be needed. Oral Contraceptives: Some studies suggest a potential interaction with oral contraceptives. Discuss this possibility with your doctor to ensure continued contraceptive efficacy. Antacids: Taking antacids may affect Cefadroxil’s absorption. Space the administration of antacids and Cefadroxil by several hours.
