What antibiotic is good for stomach infection?

Published in Antibiotic Treatment 2 mins read

Several antibiotics are used to treat bacterial stomach infections. According to Verywell Health, common antibiotics include:

  • Azithromycin (brand name Zithromax)
  • Ciprofloxacin (brand name Cipro)
  • Tetracycline



It's important to note that not all stomach infections are caused by bacteria. Some are caused by parasites, which require different medications.

Treating Bacterial Stomach Infections

If a bacterial infection is suspected, doctors may prescribe one of the antibiotics listed above. These medications work by killing or inhibiting the growth of bacteria.


Example Antibiotics and their Usage:

Antibiotic Brand Name How it works
Azithromycin Zithromax Inhibits bacterial protein synthesis, stopping bacterial growth
Ciprofloxacin Cipro Inhibits bacterial DNA replication, preventing bacteria from multiplying
Tetracycline Various Inhibits bacterial protein synthesis, preventing bacterial growth


Treating Parasitic Stomach Infections

If parasites are the cause, the following antiparasitic drugs may be used:

  • Metronidazole
  • Praziquantel
  • Albendazole


Important Considerations:

  • Diagnosis is key: It's crucial to have the infection diagnosed by a doctor before taking any medication. This ensures the correct treatment is prescribed.
  • Antibiotics are not effective against viruses: Antibiotics only treat bacterial infections, and will not help with viral infections.
  • Complete the course: It’s important to finish the entire course of antibiotics even if you start feeling better, this is to ensure the infection is completely eradicated and to avoid antibiotic resistance.
  • Side effects: Be aware of the potential side effects of antibiotics or antiparasitic drugs and discuss any concerns with your doctor.
  • Self-medicating is dangerous: Do not use antibiotics without a prescription as this can lead to antibiotic resistance and other health problems.



Always consult a healthcare professional for proper diagnosis and treatment of a stomach infection.
