What Is Bactrim Tablet?
Bactrim is an antibiotic combination medicine that contains two active ingredients: trimethoprim and sulfamethoxazole. Together, these two medicines stop the growth of bacteria and help the body fight infections. This combination is also known as co-trimoxazole.
It is important to understand that Bactrim tablet works only for bacterial infections. It does not work for viral infections like common cold, flu, or viral fever.
How Does Bactrim Tablet Work?
Bacteria need folic acid to survive and multiply. Bactrim blocks this process in two steps. Sulfamethoxazole blocks the first step, and trimethoprim blocks the next step. Because of this double action, bacteria cannot grow and slowly die, and the infection comes under control.
Bactrim Tablet Uses
Doctors prescribe Bactrim tablet for many types of bacterial infections. Some of the most common uses of Bactrim tablet are:
