Antibiotics don’t always fix bacterial problems because misuse and overuse can lead to resistance, making infections harder to treat. Sometimes, the chosen antibiotic doesn’t target the specific bacteria causing illness, or the infection is viral, where antibiotics are ineffective. For example, cephalexin capsules are prescribed for certain bacterial infections, but they won’t work against viruses like the flu or common cold. Incomplete treatment courses can also leave behind resistant bacteria, leading to recurring infections. Proper diagnosis, correct dosage, and completing the prescribed course are essential to ensure antibiotics like cephalexin capsules distributors remain effective against harmful bacteria.
