Is Bactrim DS 800-160 the proper antibiotic for a postop incision infection? (Photo)

You do not say how long it was since the discharge and treatment.  This is something that should be closely followed by in-person care from your surgeon.  Looking at the images, the red streak may be related to a dressing and the tissue doesn't look necrotic.  There is cellulitis.  Continue taking the antibiotics you have been prescribed and follow all other instructions from your doctor.  Best to you.

Thank you for your question and I am sorry to hear of your ob/gyn surgery issues. I do hope that you get better quickly.  Though Bactrim DS can cover many of the organisms responsible for a skin infection, it would be best that you see your surgeon for an in-person examination.  Though red and irritated, much of your central skin appears to have a large component of irritation, possibly with a super-imposed infection. Evaluate and record what adhesives, dressings, ointments, creams, etc where applied to your middle incision that was not placed to your others, this may lead you in the right direction.  Best wishes!

I appreciate your question.You need to discuss this with your operating surgeon.  Please follow up with your operating surgeon so he/she can examine you and recommend the most appropriate treatment plan at this time.

The best way to assess and give
true advice would be an in-person exam.

Please see a board-certified

Best to see your operating surgeon in person so he can better assess the need for additional, stronger antibiotics. Remember that infections can grow in severity very quickly so you need to follow up with your operating surgeon on a frequent basis to stay on top of it. Good luck!

Make sure you follow all the instructions of your surgeon.  The area has some characteristics of a fungal infection.
