Dear Doctor, just before few days my grandfather foley catheter was removed and he was feeling burning effect while urinating so doctor advised him to take levofloxacin 750 mg tablet namely l-cin 750 for 5 days along with alkasol. During course of medication he was not having any problem but just 1 day after stopping L-Cin 750 he is facing difficulty in urination. What should he do now. Should he use medicine for next few more days.
