Background: Previous studies have shown that several antibiotics have significant side effects in addition to their antibacterial ones, which are indirectly mediated by altering and controlling the mediators of the immune system. The synthetic antibiotics known as fluoroquinolones (FQs) were discovered that fluoroquinolones (FQs) have an impact on humoral and cellular immunity. Typically, FQs only have their moderating effects when combined with another stimulant. Conclusion: This review presented the suitability of fluoroquinolones for potential use in medicine in order to manage several infectious diseases. These FQs are highly effective antibiotics against the bacterial infections. They are therefore prone to misuse, which can result in patients experiencing unwanted side effects and the continued development of antibiotic resistance. Even though quinolones can be used empirically to treat patients in an outpatient setting, doctors still need to follow up with patients to make sure the course of antibiotics is completed and to confirm the success of the treatment. When culture and sensitivity data are available, patients should be switched to more focused antibiotics so that quinolones can be stopped. It is advisable for clinicians to use another antibiotic if a patient is at high risk for serious side effects. In order to discuss alternate antibiotics, confirm dosage, and find any drug-drug interactions, a pharmaceutical consultation may be beneficial. In order to prevent serious side effects from occurring when using quinolones, the patient and their healthcare providers should be informed by the pharmacist and the doctor. Physicians should exercise caution while treating life-threatening gram-positive infections with quinolone antibiotics, even if the more recent fluoroquinolones have demonstrated encouraging in vitro activity against gram-positive bacteria based on MIC data. Future quinolone efficacy is likely to be constrained by the ongoing abuse of these antibiotics in clinical care and agricultural feed, which will encourage gram-positive and gram-negative resistance. Overuse of one agent will eventually cause the class as a whole to become resistant.
