Topical treatment of bacterial infections affecting the mouth, gums, and oral mucosa, including gingivitis, stomatitis, and mouth ulcers where susceptible bacteria are involved.
Chlortetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing amino acid incorporation into growing peptide chains and thereby stopping bacterial growth and replication.
For topical/oral mucosal use only; avoid systemic absorption. Not recommended for use in children under 12 or during pregnancy. May cause local irritation or allergic reactions in sensitive individuals. Complete the full course as prescribed to prevent antibiotic resistance.
