Stomach upset and mild diarrhea are common, manageable side effects of Cefixime, as antibiotics can temporarily disrupt your gut's natural bacteria. To manage these symptoms: 1. Hydrate: Drink plenty of water or oral rehydration solutions to replace lost fluids. 2. Eat Bland: Stick to plain foods like rice, toast, and bananas. 3. Probiotics: Taking a probiotic supplement can help restore healthy gut flora. 4. Finish the Course: Do not stop taking Cefixime without consulting your doctor. Avoid taking over-the-counter anti-diarrheal medicines like loperamide without medical advice.\n\nContact your doctor if your symptoms worsen, or if you develop severe, watery, or bloody stools.
