Why would an immunologist put me on bactrim (sulfamethoxazole and trimethoprim) for a whole year? should i take probiotic with them? i am 53 years old and have low beta globulin.

Bactrim (sulfamethoxazole and trimethoprim) : Bactrim (sulfamethoxazole and trimethoprim) has been used for prevention of urinary tract infections. This approach is being used less these days for several reasons. Treatment for a whole year seems surprising even if your immunoglobulins (gamma globulin) are low. If you have had lots of certain infections maybe he want to prevent more. But the likelihood of getting resistance is high with chronic use of most antibiotics. Bactrim (sulfamethoxazole and trimethoprim) has been used and proven beneficial for prevention of pneumocystis pneumonia. Many immunologists might use antibiotic at the first sign of infection. Ask him/her what the evidence is for this therapy, its pros and cons. Nothing wrong with taking a probiotic with this.
