Can you use bactrim for gastritis?

Bactrim, which contains sulfamethoxazole and trimethoprim, is an antibiotic primarily used to treat bacterial infections, not gastrointestinal conditions like gastritis. Gastritis is often caused by factors such as stress, alcohol, or infections like Helicobacter pylori, which may require different treatments, such as proton pump inhibitors or specific antibiotics for H. pylori. It's important to consult a healthcare professional for an appropriate diagnosis and treatment plan for gastritis.
