What is Bactrim used for?
Bactrim (sulfamethoxazole/trimethoprim or TMP/SMX) is an antibiotic drug that combines sulfamethoxazole and trimethoprim. It is indicated to treat several infections, including urinary tract, respiratory tract, and gastrointestinal tract.
This medication consists of two drugs that effectively work together to eliminate bacteria and prevent their growth. This medication also inhibits the formation of folic acid, which is essential for bacterial growth.
Sulfamethoxazole, a sulfonamide drug, works by inhibiting the multiplication of bacteria. However, trimethoprim is an antibiotic that kills bacteria that causes infection. As a result, it improves drugs’ effectiveness.
The dosage and frequency of this medication differ from person to person, depending on your health condition, age, and tolerance. This drug is available in 400/80 mg per tablet.
The suggested dose for children suffering from UTI, acute otitis media, and shigellosis is based on their weight and should be administered twice daily at 12-hour intervals for 5 to 10 days.
The dose of Bactrim for ear infection, UTI, and chronic bronchitis is an 800/160 mg tablet twice daily for 10 to 14 days. A similar dose is given in treating shigellosis and traveler’s diarrhea for five days.
For immunocompromised adults with Pneumonia, 800/160 mg is given every six hours for 14 to 20 days; nevertheless, in terms of preventing impending infection, Bactrim should be administered once daily.
