Ampicillin + Lactobacillus is used to treat bacterial infections while supporting gut health. It combines a penicillin antibiotic with a probiotic.
This combination is commonly used for:
• Bacterial infections: Treats infections caused by susceptible gram-positive and gram-negative bacteria.
• Respiratory and urinary tract infections: Treats bacterial infections affecting the respiratory and urinary systems.
• Antibiotic-associated diarrhoea: Lactobacillus may help reduce the risk of digestive upset commonly caused by antibiotic treatment.
• Gut flora balance: Supports the natural balance of beneficial bacteria in the digestive system.

Ampicillin + Lactobacillus works through two complementary actions to treat infection while supporting gut health.
Ampicillin is a penicillin antibiotic. It works by blocking the formation of bacterial cell walls, which leads to the destruction of the bacteria and clears the infection. It is effective against susceptible gram-positive and gram-negative bacteria.
Lactobacillus is a beneficial bacterium naturally found in the digestive system. It helps maintain a healthy balance of gut flora, which can be disrupted by antibiotics, stress, or diet.
Together, these components treat bacterial infection while supporting gut microbiota during antibiotic treatment.
