Various types of bacterial infections can be treated with Sulfatrim. Uses of the antibiotic may include the treatment of ear infections, urinary tract infections, shigellosis, and a certain type of pneumonia. The medication has been approved for use in children as young as two months old. Off-label uses of the drug may also include the prevention and treatment of other types of infections.
What Is Sulfatrim Used For?Sulfatrim® (sulfamethoxazole/trimethoprim) is a combination antibiotic used to treat the following types of infections:
- Ear infections
- Urinary tract infections (UTIs), such as bladder infections
- Shigellosis (a form of dysentery)
- Traveler's diarrhea
- Acute worsening of chronic bronchitis
- A certain type of pneumonia known as Pneumocystis carinii pneumonia.
Sulfatrim is also approved to prevent Pneumocystis carinii pneumonia in people who have weakened immune systems and are at risk for the infection (such as people with HIV or AIDS).
Sulfatrim is approved for treating the infections listed above only when they are caused by certain types of bacteria. Not all bacteria will respond to Sulfatrim. Even among the types of bacteria that do respond to Sulfatrim, some strains may have become resistant and may have different resistance patterns in different regions of the country. This means that some bacteria may be susceptible to Sulfatrim in certain parts of the country, but not in others. It is important to remember that Sulfatrim is completely ineffective for treating viral illnesses (such as the common cold or the flu).
In some situations, your healthcare provider may perform certain tests to see if your particular infection is susceptible or resistant to Sulfatrim. In other situations, your healthcare provider may decide to try Sulfatrim without such tests.
