Bactrim is an antibiotic which is made up of two other antibiotics, namely sulfamethoxazole and trimethoprim. The first component belongs to a group of drugs called sulfonamides. The second is just as powerful but does not belong to any category of medicines.  It is a unique drug and has its own special properties.

Bactrim is used to treat bacterial infections of the respiratory system, ears, urinary tract and sinus. 

The two components of bactrim have special tasks which help to get rid of bacterial infection. They target the folic acid production of the bacterial cells. They target the different stages of folic acid production. Folic acid is needed for the synthesis of protein and development of DNA. Bacteria do not get folic acid from food like humans do. So, when the cells no longer get it, they will eventually be annihilated. 

Bactrim is very effective because the combination of sulfamethoxazole and trimethoprim will prevent the bacteria from getting immune to the effects of the drug. Mostly they can get resistance if there had been only one drug to deal with. This makes bactrim doubly effective. There is no way bacteria can survive with this drug in your system. 

This may give rise to the question of whether bactrim will suppress folic acid production in humans. The answer is a reassuring no. So, you can safely take this medication. It is the invading bacteria that will have to worry about the effects of bactrim. 

However, be sure to follow doctor’s instructions. Take only the prescribed amount, and only for the time duration prescribed by the doctor.
