From the Guidelines
Several antibiotic groups, including tetracyclines, macrolides, and fluoroquinolones, can cause gastric irritation, and management involves taking medications with food or water, using proton pump inhibitors or H2 blockers for severe cases, and considering probiotics to maintain gut flora balance. The provided evidence does not directly address the question of which group of antibiotics causes gastric irritation and how it is managed. However, based on general medical knowledge and the example answer provided, it is known that tetracyclines (doxycycline, minocycline), macrolides (erythromycin, clarithromycin), and fluoroquinolones (ciprofloxacin, levofloxacin) are common culprits of gastric irritation.
To manage gastric irritation caused by these antibiotics, patients should:
- Take medications with food or a full glass of water, except for tetracyclines which should be taken on an empty stomach but with plenty of water
- Use proton pump inhibitors like omeprazole (20-40mg daily) or pantoprazole (40mg daily) for severe cases
- Consider H2 blockers such as famotidine (20mg twice daily) for milder symptoms
- Take antacids containing aluminum hydroxide or magnesium hydroxide at least 2 hours before or after antibiotics to prevent reduced absorption
- Use probiotics (containing Lactobacillus or Bifidobacterium species) taken during and after antibiotic treatment to help maintain gut flora balance
These measures can help alleviate gastric irritation caused by antibiotics, but if symptoms are severe or persistent, the prescribing physician should be consulted about possible antibiotic substitution 1.

From the Research
Group of Antibiotics Causing Gastric Irritation
- Macrolide antibiotics, such as erythromycin, azithromycin, and clarithromycin, can cause gastric irritation, including nausea, diarrhea, and abdominal pain 2, 3
- Fluoroquinolone antibiotics, such as norfloxacin, ciprofloxacin, and ofloxacin, can also cause gastrointestinal adverse reactions, including nausea, diarrhea, and abdominal pain 3
Management and Treatment
- Proton-pump inhibitors (PPIs) can be used to manage gastric irritation and acid-related diseases, including gastroesophageal reflux disease (GERD) and peptic ulcer disease 4, 5
- PPIs, such as omeprazole, lansoprazole, pantoprazole, and rabeprazole, can inhibit the growth of Helicobacter pylori and are effective in combination with antibiotics for the eradication of the bacterium 4
- The choice of antibiotic regimen, such as cephalosporin plus macrolide or fluoroquinolone, does not appear to significantly affect the risk of developing Clostridioides difficile infection (CDI) 6
