Before taking Cephalexin Capsules, consult your doctor if you have allergies, especially to penicillin or other antibiotics, as reactions may occur. Inform them about kidney disease, stomach issues, or pregnancy/breastfeeding, as these can affect usage. Take cephalexin capsules exactly as prescribed typically every 6-12 hours with food or water to ensure effectiveness and avoid resistance. Don’t skip doses or stop early, even if symptoms improve. Watch for side effects like diarrhea, nausea, or rash; severe reactions (e.g., breathing difficulty) need immediate care. Avoid alcohol, as it may worsen side effects. Store Cephalexin Capsules at room temperature, away from moisture.
