Symptoms to watch for

Watch for: unusual nausea, vomiting, diarrhea (especially watery or bloody), stomach cramps, skin rash, dizziness, or signs the other medication is working differently than usual. When to seek emergency help: Severe allergic reaction (difficulty breathing, swelling of face/throat, hives), severe or persistent diarrhea (possible C. difficile infection), yellowing of skin or eyes, dark urine, or irregular heartbeat. Complete the full antibiotic course as prescribed.
