What Resprim is used for
Resprim contains the active ingredients sulfamethoxazole and trimethoprim, also known as co-trimoxazole.
Resprim is used to treat infections in different parts of the body caused by bacteria.
Resprim belongs to a group of medicines called antibiotics. There are many different types of medicines used to treat bacterial
infections. Sulfamethoxazole in Resprim belongs to a group of medicines known as sulfonamides. Trimethoprim belongs to a group
of medicines known as the benzylpyrimidines.
Resprim works by stopping the growth of the bacteria that is causing your infection.
Resprim will not work against infections caused by viruses, such as colds or flu. Resprim has been prescribed for your current
infection. Another infection later on may require a different medicine.
Your doctor may have prescribed Resprim for another reason.
Ask your doctor if you have any questions about why Resprim has been prescribed for you.
Resprim is available only with a doctor's prescription.
