Bactrim Ds Mrsa Dosage
My doctor prescribed me bactrim (sulfamethoxazole and trimethoprim) ds for mrsa. The directions are 2 twice a day. Is that a normal dose?
Yes, it can be: For MRSA (methicillin resistant staph aureus) infections, 2 ds (double strength) tabs 2x per day are often an appropriate dose. This dose is used in adults and is typically based on weight and size of the patient. Mrsa is not an infection to take lightly and properly treating this is very important. ...Read moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
I was told I had MRSA and put on bactrim ds for 10 days, twice a day. After wanting to confirm dx, the dermo did a culture and it showed nothiing! dermo thinks its just back acne. He told me to finish bactrim then he will start me on doxycycline. Is that
Sounds good: Mrsa is a scary bug but there a great many different strains and many folks harbor them on their skin with no harm. A physician seeing someone with one or more pimples may feel obligated to biopsy for MRSA and treat it as such since it's by far more serious even if it's not really present. It sounds like your dermatologist made the right move. ...Read moreSee 1 more doctor answer

My dermatologist did a swab test from the flakes on my skin since it was peeling and they said I have MRSA. They gave me Bactrim. Is it Effective?
For what?: It is effective for various things. Growing MRSA from flakes of skin is NOT a diagnosis. Such a culture will grow mrsa from many normal people. ASK THE DERMATOLOGIST TO EXPLAIN THE DIAGNOSIS and for details about exactly what you should expect. ...Read more

Dermatologist prescribed bactrim (sulfamethoxazole and trimethoprim) for mrsa. It cleared for two months, now it came back. On bactrim (sulfamethoxazole and trimethoprim) again, little to no improvement halfway through.
Go to the doctor: I hear you. If a treatment is not working, especially with a potentially deadly infection, one must change the treatment or add to the treatment. Please. It is time to get help in person for this serious problem. ...Read more

I've been taking bactrim for a MRSA infection, which is now under control. Can I take cipro (ciprofloxacin) at the same tI me for traveler's diarrhea?
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
UTI first treated with Cipro, (ciprofloxacin) 1 week later diagnosed with MRSA infection in groin area treated with Bactrim. UTI is back, could it be MRSA related?
It certainly could: be MRSA, though Bactrim (sulfamethoxazole and trimethoprim) if it worked for the groin cellulitis should also have worked well for the UTI. Go get a urine culture done at the MD office and get targeted therapy instead of just empiric antibiotics. You need a culture result. ...Read more
