Will cephalexin treat a sore thoat?

Cephalexin is an antibiotic that can treat bacterial infections, but it is not typically the first choice for sore throats unless the cause is identified as a bacterial infection, such as strep throat. Most sore throats are viral in nature and do not require antibiotics. If a bacterial cause is suspected, it's important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
