A possible treatment for recurrent UTIs that involves a single dose after intercourse is?

The treatment for recurrent urinary tract infections (UTIs) that involves a single dose after intercourse is typically Nitrofurantoin. This antibiotic is effective against the bacteria commonly responsible for UTIs and has been shown in studies to help prevent infections when taken as a prophylactic measure immediately after sexual activity.

Nitrofurantoin’s mechanism effectively targets the uropathogens causing the infection while also minimizing the risk of developing antibiotic resistance due to its short-term and limited use.

Other options like Trimethoprim, Cephalexin, and Ceflacor may be used to treat UTIs but are not usually prescribed as a single-dose preventative measure post-intercourse. Trimethoprim is more commonly used in longer-term prophylaxis rather than for acute preventative dosing, while Cephalexin and Ceflacor are broader-spectrum antibiotics that may not be tailored specifically for the prevention of recurrent UTIs in the same way Nitrofurantoin does.
