The best medicine for an intestinal infection depends on the severity of the infection and the antibiotic resistance profile of the bacteria causing it.
Most mild intestinal infections will resolve without the need for antibiotics. However, moderate to severe cases often require antibiotic treatment. According to current guidelines (Sept-2024):
-
Ampicillin: Is the preferred antibiotic for drug-sensitive strains of bacteria causing the infection.
-
Trimethoprim-sulfamethoxazole: Is recommended for ampicillin-resistant strains or in individuals with a penicillin allergy. However, resistance to this drug is also possible.
| Severity | Preferred Treatment | Alternative Treatment (if resistant/allergic) |
|---|---|---|
| Mild | Supportive care (hydration, rest) | N/A |
| Moderate/Severe | Ampicillin (if the strain is drug-sensitive) | Trimethoprim-sulfamethoxazole |
It's crucial to consult a healthcare professional for diagnosis and appropriate antibiotic selection, as antibiotic resistance patterns can vary geographically and over time. Self-treating can lead to complications and contribute to antibiotic resistance.
