You should seek medical help for diarrhea if it lasts more than two days without improvement, is accompanied by a high fever, severe abdominal pain, or signs of dehydration such as dizziness, dry mouth, or reduced urination. Bloody or black stools also require urgent care. People with weakened immune systems, young children, or older adults should consult a doctor sooner. If diarrhea develops after starting antibiotics like cephalexin capsules, it may indicate a more serious condition such as Clostridium difficile infection. In such cases, contact your healthcare provider immediately or ask reputable cephalexin capsules distributors for medication guidance.
