Trimoksazol® should only be used where, in the judgment of the physician, the benefits of treatment outweigh any possible risks; consideration should be given to the use of a single effective antibacterial agent. The in vitro susceptibility of bacteria to antibiotics varies geographically and with time; the local situation should always be considered when selecting antibiotic therapy.

2) Treatment and prophylaxis of toxoplasmosis, treatment of nocardiosis.
3) Treatment of urinary tract infections and acute exacerbations of chronic bronchitis, where there is bacterial evidence of sensitivity to Co-trimoxazole and a good reason to prefer this combination to a single antibiotic.
