Effective treatments for bacterial infections depend on the infection type and severity. Antibiotics like amoxicillin, doxycycline, or azithromycin are commonly prescribed for mild to moderate cases, targeting specific bacteria. For severe infections, ceftriaxone injection is highly effective, particularly for conditions like meningitis, gonorrhea, or complicated urinary tract infections, as it delivers potent, broad-spectrum coverage directly into the bloodstream. Treatment success requires completing the full course to prevent resistance. Probiotics may support gut health during therapy. Always consult a doctor for accurate diagnosis and tailored prescriptions, as misuse can lead to complications or resistant strains.
