Is septra (sulfamethoxazole and trimethoprim) ds prescribed for strep throat?

Is septra (sulfamethoxazole and trimethoprim) ds prescribed for strep throat?

Sulfa for Strep: Sulfonamide drugs were frequently used for Strep throat in the 1930s but fell out of favor approximately 10 years later when it was felt that bacterial resistance has developed. However, at least one study has proven this to be false, and sulfonamide drugs may be useful for this infection in patients with allergies to more traditionally used antibiotics or with multiple infections. J Clin Microbiol. Dec 2012; 50(12): 4067–4072. ...Read more

Can i take Bactrim (sulfamethoxazole and trimethoprim) ds for tinea bacterial infection?

Kinda, sorta: Bactrim (sulfamethoxazole and trimethoprim) DS is brand name for sulfamethoxazole/trimethoprim, an antibiotic used to treat bacterial infections. As such, it is not used to treat tinea or fungal infections, which require antifungals, some of which are available over-the-counter (while no antibiotics are, at least not in the States). With that said, some fungal infections can become superinfected by bacteria & thus require Bactrim (sulfamethoxazole and trimethoprim) DS ...Read more

I was just diagnosed with ca-mrsa and i'm scared since it is often resistant to drugs. I just started bactrim ds tonight. What are the chances of it not responding to any drug? How can you know if it's caught early enough? Thank you!

I was just diagnosed with ca-mrsa and i'm scared since it is often resistant to drugs. I just started bactrim ds tonight. What are the chances of it not responding to any drug? How can you know if it's caught early enough? Thank you!

Partially resistant: Ca MRSA is not particularly worse than having regular staph infection. It is not related to the flesh eating bacteria scare. The choice of antibiotics is limited, but generally the infection is sensitive to at least a few of the mainstream antibiotics of which Bactrim (sulfamethoxazole and trimethoprim) is one. If your doctor thought you were at great risk you would not be at home. ...Read more

MRSA test came back negative, but may be false neg. How soon can someone retest if they were on Bactrim (sulfamethoxazole and trimethoprim) and topical antibiotics PRIOR to test/culture?

MRSA test came back negative, but may be false neg. How soon can someone retest if they were on Bactrim (sulfamethoxazole and trimethoprim) and topical antibiotics PRIOR to test/culture?

Negative MRSA: We usually hope after treatment with Bactrim (sulfamethoxazole and trimethoprim) / topical antibiotics that we have eliminated MRSA, so retesting 3-5 days after stopping antibiotics should yield a negative result. If one is a carrier you test the nasal swabbings for MRSA. That requires longer term -6 weeks for intranasal mupirocin as treatment . Also sometimes house pets can be carriers and repeatedly infect their owners. ...Read more

Is it normal that after toe surgerywith phenol toe became red and swollen. 10dys   Bactrim (sulfamethoxazole and trimethoprim) after MRSA was found after swabbing. But Toe is still red ?

No: No, not really normal. You have a "staph" infection. So the question is whether or not the bactrim (sulfamethoxazole and trimethoprim) will be sufficient to cure it. There is a blood test called Crp that usually is used to show how your infection is responding to the antibiotics. If any question, the expertise of an infectious disease specialist can be helpful. ...Read more
