Metronidazole + Tetracycline

Uses of Metronidazole + Tetracycline

Metronidazole + Tetracycline is a combination antibiotic used to treat bacterial infections.

This combination is commonly used for:

• Helicobacter pylori infection: Helps eradicate the bacteria linked to stomach ulcers, often alongside other medicines.
• Periodontal infections: Treats susceptible bacterial infections affecting the gums and supporting structures of the teeth.
• Mixed bacterial infections: Treats infections caused by susceptible anaerobic and other bacteria.

Side effects of Metronidazole + Tetracycline

  • Nausea

  • Vomiting

  • Diarrhoea

  • Abdominal pain

  • Skin rash

How Metronidazole + Tetracycline works

Metronidazole + Tetracycline works through two separate mechanisms that stop bacteria from growing and multiplying.

Metronidazole enters bacterial cells, where its breakdown products damage bacterial DNA and lead to bacterial cell death.

Tetracycline enters bacterial cells and binds to the 30S ribosomal subunit, blocking protein synthesis. This prevents a broad range of bacteria from growing and multiplying.

Together, the two antibiotics provide broader coverage against susceptible bacteria than either antibiotic when used alone.
