Hi,
UTI stands for urinary tract infection and is caused by growth of bacteria in the urinary tract.
This may be treated with antibiotics.
Clonazepam belongs to a class called as benzodiazepine and is prescribed for various disorders.
Clonazepam directly may not cause UTI's, however it may cause an increase in the frequency of urination,
and therefore may be an indirect cause of frequent infection, especially in case of other associated factors.
Hope this helped, let me know if you may need any more information.
Best regards
